In this blog I will explain how to join a Windows 11 computer into an Active-Directory domain.
You can add any Windows machine to an Active Directory domain. In this article you can find the activation to create your own domain join.
If you host servers, applications, printers and software in Microsoft Azure, integrated with Azure AD then you may no longer need an Active-Directory environment. In a previous blog I also wrote how you can add devices without an Active-Directory environment. Before you can add your Windows computer to the domain, it is necessary that this computer has a direct connection to the domain controllers.
It is also necessary that the computer can ‘resolve’ the DNS name of the domain. Enter credentials from a domain administrator to add the Windows 11 computer to the Active-Directory domain. Now click on System and Security and then click on System. Finally, click on Advanced system settings.
Now click on the Computer Name tab and click on the Change button at the bottom:. Now click on the Domain radio button and type in the name of the domain name that you want to join this computer to. Note that on my computer, the Domain and the Network ID buttons are grayed out!
Why so? Kind of annoying, but what can you do! The Professional edition also gives you BitLocker and the ability to backup to a home or business network.

And how cold and slimy the water had been! And a fellow had once seen a big rat jump plop into the scum. The cold slime of the ditch covered his whole body; and, when the bell rang for study and the lines filed out of the playrooms, he felt the cold air of the corridor and staircase inside his clothes. He still tried to think what was the right answer. Was it right to kiss his mother or wrong to kiss his mother?
What did that mean, to kiss? You put your face up like that to say goodnight and then his mother put her face down. That was to kiss. His mother put her lips on his cheek; her lips were soft and they wetted his cheek; and they made a tiny little noise: kiss. Why did people do that with their two faces? Sitting in the study hall he opened the lid of his desk and changed the number pasted up inside from seventyseven to seventysix. But the Christmas vacation was very far away: but one time it would come because the earth moved round always.
There was a picture of the earth on the first page of his geography: a big ball in the middle of clouds. Fleming had a box of crayons and one night during free study he had coloured the earth green and the clouds maroon.
But he had not told Fleming to colour them those colours. Fleming had done it himself. He opened the geography to study the lesson; but he could not learn the names of places in America. Still they were all different places that had different names.
They were all in different countries and the countries were in continents and the continents were in the world and the world was in the universe. He turned to the flyleaf of the geography and read what he had written there: himself, his name and where he was.
Stephen Dedalus is my name, Ireland is my nation. Clongowes is my dwellingplace And heaven my expectation. He read the verses backwards but then they were not poetry. Then he read the flyleaf from the bottom to the top till he came to his own name.
That was he: and he read down the page again. What was after the universe? But was there anything round the universe to show where it stopped before the nothing place began? It could not be a wall but there could be a thin thin line there all round everything. It was very big to think about everything and everywhere. Only God could do that. He tried to think what a big thought that must be but he could only think of God. It made him very tired to think that way. It made him feel his head very big.
He turned over the flyleaf and looked wearily at the green round earth in the middle of the maroon clouds. He wondered which was right, to be for the green or for the maroon, because Dante had ripped the green velvet back off the brush that was for Parnell one day with her scissors and had told him that Parnell was a bad man.
He wondered if they were arguing at home about that. That was called politics. There were two sides in it: Dante was on one side and his father and Mr Casey were on the other side but his mother and uncle Charles were on no side. Every day there was something in the paper about it. It pained him that he did not know well what politics meant and that he did not know where the universe ended.
He felt small and weak. When would he be like the fellows in poetry and rhetoric? They had big voices and big boots and they studied trigonometry. That was very far away. First came the vacation and then the next term and then vacation again and then again another term and then again the vacation. It was like a train going in and out of tunnels and that was like the noise of the boys eating in the refectory when you opened and closed the flaps of the ears.
Term, vacation; tunnel, out; noise, stop. How far away it was! It was better to go to bed to sleep. Only prayers in the chapel and then bed. He shivered and yawned. It would be lovely in bed after the sheets got a bit hot. First they were so cold to get into. He shivered to think how cold they were first. But then they got hot and then he could sleep. It was lovely to be tired. He yawned again. Night prayers and then bed: he shivered and wanted to yawn.
It would be lovely in a few minutes. He felt a warm glow creeping up from the cold shivering sheets, warmer and warmer till he felt warm all over, ever so warm and yet he shivered a little and still wanted to yawn. The bell rang for night prayers and he filed out of the study hall after the others and down the staircase and along the corridors to the chapel.
The corridors were darkly lit and the chapel was darkly lit. Soon all would be dark and sleeping. There was cold night air in the chapel and the marbles were the colour the sea was at night. The sea was cold day and night: but it was colder at night.
But the kettle would be on the hob to make punch. O Lord, open our lips And our mouths shall announce Thy praise. Incline unto our aid, O God! O Lord, make haste to help us! There was a cold night smell in the chapel.
But it was a holy smell. It was not like the smell of the old peasants who knelt at the back of the chapel at Sunday mass. That was a smell of air and rain and turf and corduroy. But they were very holy peasants. They breathed behind him on his neck and sighed as they prayed. They lived in Clane, a fellow said: there were little cottages there and he had seen a woman standing at the halfdoor of a cottage with a child in her arms, as the cars had come past from Sallins.
It would be lovely to sleep for one night in that cottage before the fire of smoking turf, in the dark lit by the fire, in the warm dark, breathing the smell of the peasants, air and rain and turf and corduroy.
But, O, the road there between the trees was dark! You would be lost in the dark. It made him afraid to think of how it was. He heard the voice of the prefect of the chapel saying the last prayer. He prayed it too against the dark outside under the trees. Visit, we beseech Thee, O Lord, this habitation and drive away from it all the snares of the enemy. May Thy holy angels dwell herein to preserve us in peace and may Thy blessing be always upon us through Christ our Lord. His fingers trembled as he undressed himself in the dormitory.
He told his fingers to hurry up. He had to undress and then kneel and say his own prayers and be in bed before the gas was lowered so that he might not go to hell when he died. He rolled his stockings off and put on his nightshirt quickly and knelt trembling at his bedside and repeated his prayers quickly, fearing that the gas would go down.
He felt his shoulders shaking as he murmured:. God bless my father and my mother and spare them to me! God bless my little brothers and sisters and spare them to me! God bless Dante and uncle Charles and spare them to me! He blessed himself and climbed quickly into bed and, tucking the end of the nightshirt under his feet, curled himself together under the cold white sheets, shaking and trembling.
But he would not go to hell when he died; and the shaking would stop. A voice bade the boys in the dormitory goodnight. He peered out for an instant over the coverlet and saw the yellow curtains round and before his bed that shut him off on all sides. The light was lowered quietly. Down the staircase and along the corridors or to his room at the end? He saw the dark. Was it true about the black dog that walked there at night with eyes as big as carriagelamps?
They said it was the ghost of a murderer. A long shiver of fear flowed over his body. He saw the dark entrance hall of the castle. Old servants in old dress were in the ironingroom above the staircase. It was long ago. The old servants were quiet. There was a fire there but the hall was still dark.
A figure came up the staircase from the hall. He wore the white cloak of a marshal; his face was pale and strange; he held his hand pressed to his side. He looked out of strange eyes at the old servants. But only the dark was where they looked: only dark silent air. Their master had received his deathwound on the battlefield of Prague far away over the sea. He was standing on the field; his hand was pressed to his side; his face was pale and strange and he wore the white cloak of a marshal.
O how cold and strange it was to think of that! All the dark was cold and strange. There were pale strange faces there, great eyes like carriagelamps. They were the ghosts of murderers, the figures of marshals who had received their deathwound on battlefields far away over the sea. What did they wish to say that their faces were so strange? Going home for the holidays! That would be lovely: the fellows had told him. Getting up on the cars in the early wintry morning outside the door of the castle.
The cars were rolling on the gravel. Cheers for the rector! The cars drove past the chapel and all caps were raised. They drove merrily along the country roads. The drivers pointed with their whips to Bodenstown. The fellows cheered. They passed the farmhouse of the Jolly Farmer.
Cheer after cheer after cheer. Through Clane they drove, cheering and cheered. The peasant women stood at the halfdoors, the men stood here and there. The lovely smell there was in the wintry air: the smell of Clane: rain and wintry air and turf smouldering and corduroy.
The train was full of fellows: a long long chocolate train with cream facings. The guards went to and fro opening, closing, locking, unlocking the doors. They were men in dark blue and silver; they had silvery whistles and their keys made a quick music: click, click: click, click.
And the train raced on over the flat lands and past the Hill of Allen. The telegraph poles were passing, passing. The train went on and on. It knew. There were holly and ivy round the pierglass and holly and ivy, green and red, twined round the chandeliers. There were red holly and green ivy round the old portraits on the walls. Holly and ivy for him and for Christmas. All the people. Welcome home, Stephen! Noises of welcome. His mother kissed him.
Was that right? His father was a marshal now: higher than a magistrate. There was a noise of curtainrings running back along the rods, of water being splashed in the basins. There was a noise of rising and dressing and washing in the dormitory: a noise of clapping of hands as the prefect went up and down telling the fellows to look sharp.
A pale sunlight showed the yellow curtains drawn back, the tossed beds. His bed was very hot and his face and body were very hot. He got up and sat on the side of his bed. He was weak. He tried to pull on his stocking. It had a horrid rough feel. The sunlight was queer and cold. A fellow held his arms while he loosened the stocking clinging to his foot and climbed back into the hot bed.
He crouched down between the sheets, glad of their tepid glow. He heard the fellows talk among themselves about him as they dressed for mass. It was a mean thing to do, to shoulder him into the square ditch, they were saying.
His father had told him, whatever he did, never to peach on a fellow. He shook his head and answered no and felt glad. The face and the voice went away. Sorry because he was afraid. Afraid that it was some disease. Canker was a disease of plants and cancer one of animals: or another different. That was a long time ago then out on the playgrounds in the evening light, creeping from point to point on the fringe of his line, a heavy bird flying low through the grey light.
Leicester Abbey lit up. Wolsey died there. The abbots buried him themselves. He was not foxing. No, no: he was sick really. That was the way a rat felt, slimy and damp and cold.
Every rat had two eyes to look out of. Sleek slimy coats, little little feet tucked up to jump, black slimy eyes to look out of. They could understand how to jump. But the minds of rats could not understand trigonometry. When they were dead they lay on their sides.
Their coats dried then. They were only dead things. The prefect was there again and it was his voice that was saying that he was to get up, that Father Minister had said he was to get up and dress and go to the infirmary. And while he was dressing himself as quickly as he could the prefect said:. He was very decent to say that. That was all to make him laugh. But he could not laugh because his cheeks and lips were all shivery: and then the prefect had to laugh by himself.
They went together down the staircase and along the corridor and past the bath. As he passed the door he remembered with a vague fear the warm turfcoloured bogwater, the warm moist air, the noise of plunges, the smell of the towels, like medicine.
Brother Michael was standing at the door of the infirmary and from the door of the dark cabinet on his right came a smell like medicine. That came from the bottles on the shelves.
The prefect spoke to Brother Michael and Brother Michael answered and called the prefect sir. He had reddish hair mixed with grey and a queer look. It was queer that he would always be a brother. It was queer too that you could not call him sir because he was a brother and had a different kind of look.
Was he not holy enough or why could he not catch up on the others? There were two beds in the room and in one bed there was a fellow: and when they went in he called out:. He was a fellow out of the third of grammar and, while Stephen was undressing, he asked Brother Michael to bring him a round of buttered toast. He bent down to rake the fire.
He had a long back like the long back of a tramhorse. He shook the poker gravely and nodded his head at the fellow out of third of grammar. Then Brother Michael went away and after a while the fellow out of third of grammar turned in towards the wall and fell asleep. That was the infirmary.
He was sick then. Had they written home to tell his mother and father? But it would be quicker for one of the priests to go himself to tell them. Or he would write a letter for the priest to bring. Dear Mother, I am sick. I want to go home. Please come and take me home. I am in the infirmary. Your fond son, Stephen. How far away they were! There was cold sunlight outside the window.
He wondered if he would die. You could die just the same on a sunny day. He might die before his mother came. Then he would have a dead mass in the chapel like the way the fellows had told him it was when Little had died. All the fellows would be at the mass, dressed in black, all with sad faces.
Wells too would be there but no fellow would look at him. The rector would be there in a cope of black and gold and there would be tall yellow candles on the altar and round the catafalque. And they would carry the coffin out of the chapel slowly and he would be buried in the little graveyard of the community off the main avenue of limes. And Wells would be sorry then for what he had done. And the bell would toll slowly. The castle bell! Farewell, my mother! Bury me in the old churchyard Beside my eldest brother.
My coffin shall be black, Six angels at my back, Two to sing and two to pray And two to carry my soul away.
How beautiful and sad that was! How beautiful the words were where they said Bury me in the old churchyard! A tremor passed over his body. How sad and how beautiful! He wanted to cry quietly but not for himself: for the words, so beautiful and sad, like music. The bell! O farewell! The cold sunlight was weaker and Brother Michael was standing at his bedside with a bowl of beeftea. He was glad for his mouth was hot and dry. He could hear them playing in the playgrounds. And the day was going on in the college just as if he were there.
Then Brother Michael was going away and the fellow out of the third of grammar told him to be sure and come back and tell him all the news in the paper. He told Stephen that his name was Athy and that his father kept a lot of racehorses that were spiffing jumpers and that his father would give a good tip to Brother Michael any time he wanted it because Brother Michael was very decent and always told him the news out of the paper they got every day up in the castle.
There was every kind of news in the paper: accidents, shipwrecks, sports and politics. Do your people talk about that too? My name is the name of a town. Your name is like Latin. Do you see the joke? Athy is the town in the county Kildare and a thigh is the other thigh.
He looked at Stephen over the bedclothes as he spoke. Then he lay back on the pillow and said:. Why did he not tell it? Then why was he sent to that place with them? But his father had told him that he would be no stranger there because his granduncle had presented an address to the Liberator there fifty years before.
You could know the people of that time by their old dress. It seemed to him a solemn time: and he wondered if that was the time when the fellows in Clongowes wore blue coats with brass buttons and yellow waistcoats and caps of rabbitskin and drank beer like grownup people and kept greyhounds of their own to course the hares with.
He looked at the window and saw that the daylight had grown weaker. There would be cloudy grey light over the playgrounds. There was no noise on the playgrounds. The class must be doing the themes or perhaps Father Arnall was reading out of the book. It was queer that they had not given him any medicine. Perhaps Brother Michael would bring it back when he came. They said you got stinking stuff to drink when you were in the infirmary.
But he felt better now than before. It would be nice getting better slowly. You could get a book then. There was a book in the library about Holland. There were lovely foreign names in it and pictures of strangelooking cities and ships. It made you feel so happy. How pale the light was at the window! But that was nice. The fire rose and fell on the wall. It was like waves. Someone had put coal on and he heard voices.
They were talking. It was the noise of the waves. Or the waves were talking among themselves as they rose and fell. He saw the sea of waves, long dark waves rising and falling, dark under the moonless night.
A tall man stood on the deck, looking out towards the flat dark land: and by the light at the pierhead he saw his face, the sorrowful face of Brother Michael. He saw him lift his hand towards the people and heard him say in a loud voice of sorrow over the waters:. We saw him lying upon the catafalque. A wail of sorrow went up from the people. A great fire, banked high and red, flamed in the grate and under the ivytwined branches of the chandelier the Christmas table was spread.
They had come home a little late and still dinner was not ready: but it would be ready in a jiffy, his mother had said. They were waiting for the door to open and for the servants to come in, holding the big dishes covered with their heavy metal covers.
All were waiting: uncle Charles, who sat far away in the shadow of the window, Dante and Mr Casey, who sat in the easychairs at either side of the hearth, Stephen, seated on a chair between them, his feet resting on the toasted boss. Mr Dedalus looked at himself in the pierglass above the mantelpiece, waxed out his moustache ends and then, parting his coat tails, stood with his back to the glowing fire: and still from time to time he withdrew a hand from his coat tail to wax out one of his moustache ends.
Mr Casey leaned his head to one side and, smiling, tapped the gland of his neck with his fingers. And Stephen smiled too for he knew now that it was not true that Mr Casey had a purse of silver in his throat.
He smiled to think how the silvery noise which Mr Casey used to make had deceived him. Mr Casey tapped the gland of his neck and smiled at Stephen with sleepy eyes: and Mr Dedalus said to him:.
O, well now, we got a good breath of ozone round the Head today. Ay, bedad. Mr Dedalus dropped his coat tails and went over to the sideboard. He brought forth a great stone jar of whisky from the locker and filled the decanter slowly, bending now and then to see how much he had poured in.
Then replacing the jar in the locker he poured a little of the whisky into two glasses, added a little water and came back with them to the fireplace. He inclined his head, closed his eyes, and, licking his lips profusely, began to speak with the voice of the hotel keeper. Mr Casey was still struggling through his fit of coughing and laughter.
The servants entered and placed the dishes on the table. Mrs Dedalus followed and the places were arranged. When all had taken their seats he laid his hand on the cover and then said quickly, withdrawing it:. All blessed themselves and Mr Dedalus with a sigh of pleasure lifted from the dish the heavy cover pearled around the edge with glistening drops. Stephen looked at the plump turkey which had lain, trussed and skewered, on the kitchen table. Why did Mr Barrett in Clongowes call his pandybat a turkey?
But Clongowes was far away: and the warm heavy smell of turkey and ham and celery rose from the plates and dishes and the great fire was banked high and red in the grate and the green ivy and red holly made you feel so happy and when dinner was ended the big plum pudding would be carried in, studded with peeled almonds and sprigs of holly, with bluish fire running around it and a little green flag flying from the top.
It was his first Christmas dinner and he thought of his little brothers and sisters who were waiting in the nursery, as he had often waited, till the pudding came. The deep low collar and the Eton jacket made him feel queer and oldish: and that morning when his mother had brought him down to the parlour, dressed for mass, his father had cried.
That was because he was thinking of his own father. And uncle Charles had said so too. Then he asked uncle Charles was it tender. Uncle Charles could not speak because his mouth was full but he nodded that it was. It is a question of public morality. A priest would not be a priest if he did not tell his flock what is right and what is wrong.
Not another word now. It would be better for him that a millstone were tied about his neck and that he were cast into the depths of the sea rather than that he should scandalise one of these, my least little ones. That is the language of the Holy Ghost. I meant about the I was thinking about the bad language of the railway porter. Here, Stephen, show me your plate, old chap. Eat away now. Mrs Dedalus was eating little and Dante sat with her hands in her lap.
She was red in the face. Mr Dedalus rooted with the carvers at the end of the dish and said:. If any lady or gentleman He held a piece of fowl up on the prong of the carvingfork. Nobody spoke. He put it on his own plate, saying:. He looked round at the others whose faces were bent towards their plates and, receiving no reply, waited for a moment and said bitterly:.
Is it for Billy with the lip or for the tub of guts up in Armagh? He has a handsome face, mind you, in repose. O Johnny! He twisted his features into a grimace of heavy bestiality and made a lapping noise with his lips.
Let him remember that too when he grows up. When he was down they turned on him to betray him and rend him like rats in a sewer. Lowlived dogs! And they look it! Choosing the upgrade path using the “Get Windows 10” app over the clean install will also help users to install the right edition of the operating system. A clean installation requires to manually download the correct version of Windows 10 that will upgrade your system.
Technically, upgrading through Windows Update should be the easiest and safest way to make the move to Windows However, performing an upgrade can also be problematic. You can stumble upon errors caused by pre-existing issues in your system. After the upgrade, there are chances that applications and peripherals may not work correctly, and it could result on additional time trying to troubleshoot and fix the problems. Quick tip: If you’re planning to upgrade, make sure to uninstall any security software, such as antivirus, and software you don’t need.
Take the time and check online to verify your hardware and software are compatible with Windows Also, make sure to disconnect any peripherals, such as printers, scanners, and USB devices to avoid possible errors. Another advantage worth to point out is that performing an upgrade will also allow you to roll back to Windows 7 or Windows 8.
You can’t do this if you perform a clean install by booting from the Windows 10 installation media. If you have a custom computer or you want to start from scratch with a clean installation of Windows 10, you can opt to format the hard drive and start with a clean install of Windows There are many advantages performing a clean install of Windows For example, a clean install is an opportunity to start fresh from scratch without any bloatware and trial software that might have come pre-installed with your system.
You will also regain control over your apps, as you can now install only the applications you need, and you’ll also start with a brand new and clean Windows Registry. Also, your chances of running into errors and other issues will significantly be reduced. If your PC had any software or hardware issues, doing a clean install likely resolves any problems.
While a clean install is always the way to go for many technical users, upgrading to Windows 10 can be tricky. Microsoft is allowing users to perform a clean install of the operating system when upgrading from Windows 7 or Windows 8. However, it requires users to upgrade before the product keys can work on a clean install of Windows Otherwise, chances are, your installation won’t activate correctly.
Starting from scratch also takes longer than doing a plain in-place upgrade because you’ll need to reinstall and reconfigure any software you previously had. It also requires that you have the applications installation files and products keys.
If the Windows setup can’t recognize different hardware in your computer, you’ll have to manually find and install all the necessary drivers. Sometimes, it’s not an easy task.
Besides deleting all your applications and settings, performing a clean installation of Windows will delete all your files. Make sure you backup all your data before using the upgrade path. Microsoft doesn’t offer an option to do a clean install if you’re upgrading using Windows Update. The only way to perform a clean install is by manually downloading the Windows 10 installation files.
Choosing the “Upgrade this PC now” will give you the choice to keep all of your files and apps. If you choose to keep your files and apps, you will be doing an in-place upgrade. Choosing not to keep your files and apps can be considered as the option to do a clean install.
Personally, I like to create an installation media. This way I can have a better control on how Windows 10 will install, as I can reorganize the hard drive partitions as well. It’s worth noting that doing a clean install will prompt users to enter their product key. It’s not a big deal, but it’s something to keep in mind.
Also, performing a clean install with a bootable media won’t offer the option to roll back. In practice, it’s always better to start fresh with a clean install of Windows, even more if you’ve been running the same installation for quite some time. While there are multiple methods to upgrade to Windows 10, both in-place upgrade and clean install have their benefits and disadvantages.
Microsoft has been making various improvements in the upgrade process to the point that an in-place upgrade looks like a true solution for most users, but it all comes down to what you feel more comfortable doing. Microsoft wants and recommends users to upgrade to Windows 10 by reserving their copies using the “Get Windows 10” app, which only offers the option of an in-place upgrade. This way allows users to keep their files and apps, which is a great choice for regular users.
I like to do a clean install of the operating system even though it takes more time and more work. Also, knowing that Microsoft is offering Windows as a Service, I will probably be avoiding some upgrade issues in the early days. Mauro Huculak is technical writer for WindowsCentral. His primary focus is to write comprehensive how-tos to help users get the most out of Windows 10 and its many related technologies. Windows Central Windows Central.
Mauro Huculak. Topics Windows. See all comments I made an upgrade and choose to keep nothing. It was almost the same thing to me as a clean one, Windows 10 started as a pretty new OS installed.
How did you manage to put an emoji in your comment? Too Windows XPish lol I definitely gonna miss that all night formating and installing Windows through a CD drive, installing a million of drivers and programs and one month later do it all over again lol good old times. But seriously this upgrade option works perfectly, practically removes everything. I did the upgrade and keep everything. I do installs every day! So I was lazy and did the upgrade, glad I did.
I second to that! I did my upgrade to win 10, it’s great. Why it’s so huge in size, 57Gb? If i have to do a clean upgrade, how can i do it without entering the product key as i don’t have it. My pc came preinstalled with the windows 7 and an image back-up on my HDD.
You need to run disk cleanup to remove the windows. Hi Arthur, I dont know if you are still interested in dooing a clean install of windows 10 or not but if you still want to do it here is the solution to your lost windows key, this helped me to get my lenovo preinstalled windows key from the hard drive before I did a clean install. Download a third party app that can find and view your windows, office, etc product keys, it basically dig these info from inside the system files.
Copy the key s you need, preferably email a copy to yourself, this way you can do a fresh install without fear of being stuck with an unactivated windows or the need to buy a new windows licnese, BUT you need to know that before freshly install windows 10, you need to upgrade first and when that is done which you already did then and only then you can do a clean install and Microsoft will accept your old windows Key for the clean install of windows 10, otherwise it will force you to buy a new license key.
There are many third party key finder apps: 1. Yeah using the download tool and choosing to upgrade now BUT delete all files and programs option seems pretty legit. No need to go thru the trouble of burning the boot media.
You can even choose to just keep your files and only delete programs. Just be sure once you’re activated and everything’s good, run disk cleaner and delete old windows install and temp windows install files. There is a third option. Use disk clean up on c drive. It will remove the Windows old folder and give you at least 50 gb of space. How about Reset option in Settings, doesn’t it works as reset works in phone and can replaces the need for doing clean installation of Windows Where can I find that?
Alternatively, is there any reason not to do the upgrade, keeping everything, but if there’s an issue just use the refresh or reset option?
Many ppl did not notice this but doing a clean install gave windows a mb reserve drive, upgrade doesnt change the size of the drive. There must be a reason they increase the size from win7-win8-win Icyasd in fact there are two now, and i’ve noticed them since the first install of the technical p. The mb is still there and they made another mb which i find kind of funny, i like to have full control over my stuff and this new added mb reserve i don’t like.
But there’s a windows. That cannot be gotten rid of easily. Although it will be deleted by itself within 30 days. I’ve never seen an. One of the main things I hate about windows is the object security settings. More often than not, when you get an error saying that you do not have the priviledges to delete a file, you actually do have full control and cant delete it anyways.
Use Unlocker to delete folder, fastest and easiest way to do it. You don’t have to worry about the windows. Windows 10 will automatically remove the windows.
Pls do help me.. So it erases your user files kept under ‘Users’ etc. At least I did that and it worked that way disclaimer – that isn’t documented well so recheck for yourself.
But I didn’t have much to worry about Always backup things, or test on something not important. Other drives should be fine also but I didn’t have that to check, I presume since my C wasn’t touched either except for the above. If you have a ssd is a clean better since windows old folder is like huge! The upgrade worked for me on my XPS I upgraded my SP3, my moms laptop, and an older dell laptop with no problems. I upgraded my older dell xps pc and my sound card is really low on the volume, I’ve checked all available settings, updates and even went to the dell website for newer drivers and such.
I did a clean install of my dell vostro domain PC at work with no problems. Upgrade is way better. No one likes to take the full job of backing up or reinstalling everything. I’d rather just keep my w8. That’s why I just upgraded and kept everything. It runs perfectly. You should already have backups going With no back up, one would be temporarily hosed. Men dont back up.
Men cry! Been backing up ever since. So I’ll be making a clean install. Clean install just to be safe I’ve always done a clean install but this time I tried upgrade as I didn’t have too much junk on my machine and so far all seems sweet so I’ll probably keep it this way.
I did both, upgrade is better, but had to clean install for Cortana to work on my domain PC so it depends. Hmmm interesting. Clean or not i dont mind, my pc gets faster after getting windows I would’ve done an in-place upgrade if I got the GWX notification.
Wanted to do a clean install to “start fresh” from the insider program and now my windows won’t activate haha. I’ve read that it’s an issue on MS’s side, but after my SP3 still not being activated after 5 days, I’m skeptical. Do your updates and you’ll get it. Too late lol. I’ve been upgraded since the first day. Point is, it’s not activated. Also, not true, because it didn’t show up. Even spent two hours total with MS tech support on getting the update through, but they couldn’t figure it out either.
You don’t need to wait for that gwx whatever is this, you could download the Media tool from MS and perform a upgrade from there. After that you could make a clean. Thats what I did lol.
Have you upgraded from 8. Worked just fine for me, it is the bugs that are bothering me, sometimes the icon highlighting disappears and it is hard to know whether I have selected or not. Edge doesn’t render some sites perfectly. All in all it’s been good. And so much for keeping anti virus off, fortunately Norton didn’t cause any major upsets. Yes, i have 5 machines who are upgraded with a legit product key, however i have 1 laptop which came with Windows Vista, so no free upgrade, just install Windows 8.
It’ll get activated.. But after the upgrade and activation, if I want to do the clean, will it work with the same key? Once it gets activated then. And if you have doubt.. I’ve 2 Systems running with it.. Doing a rollback failed depending on the position of the sun, it thought I have Windows 7, 8 or 8. Atleast the system did register onto my MS account, so a clean install activated fine. Another 7 ultimate to 8.
I have 1 more pc that is a 7 ultimate upgraded to 8. I may hold off on the last machine, as I may have to upgrade the Motherboard. My point? Better upgrade Windows 7 to 10 directly then, so you have another copy of Windows 10 with the 8 product key. Wow, very well thought ; I didn’t think of this. Makes a difference ;-. I just had to reset my surface because that upgrade caused so many issues. I don’t even know where to begin with them.
I like clean install so for now, I will wait till I can save up to buy Windows I like to buy it anyway. I did the upgrade and just reset my PC Figured that was the same as a clean install Same here. Can’t see why it wouldn’t be the same other than you end up with that Windows.
This gave me a BSOD loop :. I upgraded, and the OS was painfully slow I’d had the preview for months on a partition and never had any issues, but the upgrade didn’t get along with something or other. So I went with the clean install Windows 10 is humming along almost perfectly Clean, windows 8 carries over bugs :. When I did a clean install of Windows 10 on my Dell , Bluetooth wasn’t working and there was no way to install the right driver.
So, I had to reinstall Windows 8. Same thing happened with my Sony vaio. Clean install, no Bluetooth. Not even detecting it. Then I rolled back to windows 7 and upgraded from there. Now everything works like a charm! I have a somewhat generic notebook, that doesn’t have bluetooth on it, and I use a BT Adaptor, so he plugged my adaptor and connected a phone and, when he disconnected my adaptor BANGHO’s bluetooth started working and he hasn’t had any other problem with it.
Force upgraded my Dell venue 8 pro and I’m thinking that a clean install would have freshened up my little companion as either it’s bored down with legacy stuff or Windows 10 is in need of some immediate work and optimization.
Not sure how a clean install might fix hardware issues This is no when you better clean install. I chose to clean install on here becuase I wanted just to have fun getting on recovery thing and doing command promt stuff but Windows installation moves everything to windows.
No man, just no. I’ve done tens of thousands of both over the years and never liked upgrades. With the 40 plus upgrades under my best so far, not one has been an issue and has already saved hundreds of hours. Clean installs I can’t say the same. Clean is always better. I choose to upgrade and keep the files. And I’ll wait for some bugs fixes before I made a real clean install. Maybe a clean install just at the end of this year, I don’t know.
Lets see. For the free dvd app that would be another reason to upgrade not much else unless you bought from an OEM that has slic product key. Ah, that shot. Windows 10 is such a beautiful OS. And I prefer Clean Install. I heard a few ‘legacy’ machines could run Win10 relatively smooth, so it gives me confidence in an immediate upgrade process We installed it on some really low-end HP netbooks and runs slightly better then 7 Starter Edition.
List of available tasks will be presented. This time there is no need to select server configuration because Business Central keeps track of recently selected configuration on different screens. At the same time you have created your first business process and made successful integration between your business application and Business Central.
You will enhance your business application with business assets that execute custom business logic and monitors execution via event listeners. Implement the executeWorkItemHandler by simply printing out work item and complete the work item. To be able to monitor execution of our business assets such as business process an event listener can be implemented.
In this tutorial we focus on ProcessEventListener but there are other types such as:. Create class MyProcessEventListener that implements org. At this point all development effort is done, the last remaining thing is to pull back the business assets project into the business-application-kjar project. You should see two of them. Looking into the application logs console you should see that both the handler has been executed and event listener was notified about various events.
With this knowledge you can start doing more advanced service tasks that will integrate your application with the outside world. You will enhance your business application with JPA entity that will be used both by your business application service and business assets.
Add new marshalling strategy with following value new org. This illustrates that an instance has been created, it has one user task assigned the owner is wbadmin and it has two process variables. With the power of business automation and JPA you learned how to externalise data managed by automated by business processes.
You will build business application that pushes out information about your business automation processes, cases, tasks directly to an ElasticSearch server. To get quickly up and running with ElasticSearch, make use of docker images provided by ElasticSearch. To get started with business applications the easiest way is to generate it. There are several configuration parameters that define how business application will connect to ElasticSearch server.
You should see just one. When you complete a task or abort a process instance data in ElasticSearch will be immediately updated. Now you can take advantage of all the good things ElasticSearch provides you with such as full text search by process variables, task assignees, case participants and more. You will build business application that uses JMS to send information between your business processes. It combines process logic and messaging to provide comprehensive solution to common problems such as – how to notify other participants of particular event.
Download and unzip Apache Artemis distribution. Once downloaded, navigate to the location where you want to store your broker data and create new broker. Sample business process should be a single script task and end signal event.
Signal event should use external scope and define a signal IamDone. Process should define single process variable input that is then mapped as data output of the end event.
Sample business process should be a signal catch event and single user task assigned to wbadmin. The catch signal event should use the signal same as throwing one and that is IamDone. Process should define single process variable data that is then mapped as data input of the catch event. There are several configuration parameters that define how business application will connect to Apache Artemis. Then create a new class that will be responsible for sending signals over JMS.
This will be really small extension to out of the box JMS work item handler. Last but not least, annotate the class with Component annotation so it will be automatically registered as work item handler. Below is the complete source code of the handler implementation. Last development activity is to create the message receiver. This is even easier than sender as there is out of the box receiver from jBPM – org. You should see two processes:.
Verify that there is a user task assigned to wbadmin user with information coming from second process instance – hello. Next, go to process definitions in Manage section of the Home screen and select server configuration top right corner – again it should be business-application-service-dev the list of available process definition will be loaded and you should see your single process definitions from the project business-application-kjar.
First start process instance that will wait for a signal catchsignalprocess , then start process instance that will throw send signal via JMS throwsignalprocess. When starting second process specify the input you want to send together with signal. Go to Task inbox from home screen to see that task is created with input provided on the second process instance.
Moreover, you made business processes to talk to each other over signals. This allows you to build more advanced interactions based on your business logic. You will enhance your business application with some dynamic assets that allow more adaptive approach to business logic compared with structured business processes. You will see your newly imported project named business-application-kjar.
You can now create your dynamic case definition that does not have to have connected process activities. Sample case definition could be a two user tasks that will be assigned to user wbadmin and not connected to anything else.
Both of them are assigned to wbadmin user although only one second will be created automatically when case instance is created.
This is because it is marked as autostart and thus will be directly created. To do so, edit standalone. Next, go to process definitions in Manage section of the Home screen and select server configuration top right corner – again it should be business-application-service-dev the list of available process definition will be loaded and you should see your single case definition from the project business-application-kjar. Examine details of that case definition by clicking on the row in the table.
Switch to Diagram tab to see the visual representation of your case definition. Business Central does not allow to start case instances and thus you need to switch to Case Management showcase application. It is accessible from the Apps launcher icon top right corner next to logout button. Launch the application and login with wbadmin.
Once logged in you can start a new case instance. From there you can start a new instance of Dynamic User Task as the other one is already there. This script assumes you have Java JDK 1. To check whether Java and Ant are installed correctly, type the following commands inside a command prompt:. First of all, you need to download the installer and unzip it on your local file system. There are two versions. In general, it is probably best to download the full installer: jBPM You can also download the latest build only for the minimal installer.
The easiest way to get started is to simply run the installation script to install the demo setup. The demo install will setup all the web tooling on top of WildFly and Eclipse tooling in a pre-configured setup. Go into the jbpm-installer folder where you unzipped the installer and from a command prompt run:. Running this command could take a while REALLY, not kidding, we are for example downloading an Eclipse installation, even if you downloaded the full installer, specifically for your operating system.
If you want to avoid downloading specific components because you will not be using them or you already have them installed somewhere else , check below for running only specific parts of the demo or directing the installer to an already installed component. Once the demo setup has finished, you can start playing with the various components by starting the demo setup:. It could take a minute to start up the application server and web application. Once everything is started, you can start playing with the Eclipse and web tooling, as explained in the following sections.
If you only want to try out the web tooling and do not wish to download and install the Eclipse tooling, you can use these alternative commands:. Similarly, if you only want to try out the Eclipse tooling and do not wish to download and install the web tooling, you can use these alternative commands:. Now continue with the minute tutorials.
Using a prebuilt Evaluation example, the following screencast gives an overview of how to manage your process instances. It shows you:. Business Central supports the entire life cycle of your business processes: authoring, deployment, process management, tasks and dashboards. The project authoring page allows you to look at existing repositories, where each project can contain business processes but also business rules, data models, forms, etc.
It allows you to create your own project, or you could import an existing example to take a look at. To make a process available for execution, you need to successfully build and deploy it first. To manage your process definitions and instances, click the “Process Management” menu option at the top menu bar and select one of the available options depending on you interest:.
Process Instances – lists all active process instances allows to show completed, aborted as well by changing filter criteria.
The process definitions view allows you to start a new process instance by clicking on the Start button. The process form as defined in the project will be shown, where you need to fill in the necessary information to start the process.
In this case, you need to fill the user you want to start an evaluation for for example use “krisv” and a reason for the request, after which you can complete the form.
Some details about the process instance that was just started will be shown in the process instance details panel. From there you can access additional details:. The process instance that you just started is first requiring a self-evaluation of the user and is waiting until the user has completed this task. To see the tasks that have been assigned to you, choose the “Tasks” menu option on the top bar.
By default, it will show all active tasks, and a “Performance Evaluation” that was created by the process instance you just started should be available for you.
When you click a task, the task details will be shown, including the task form related to this task. After starting the task, you can fill in the necessary information and complete the task.
After completing the task, you could check the “Process Instances” once more to check the progress of your process instance. You should be able to see that the process is now waiting for your HR manager and project manager to also perform an evaluation. This is a set of predefined charts that allow users to spot what is going on in the system.
Charts can be fully customized as well, as explained in the Business Activity Monitoring chapter. The following screencast gives an overview of how to use the Eclipse tooling. You can open up the evaluation process and the ProcessTest class. The console should show how the process was started and how the different actors in the process completed the tasks assigned to them, to complete the process instance. You could also create a new project using the jBPM project wizard.
The sample projects contain a process and an associated Java file to start the process. Select to create a project with some example files to get you started quickly and click next. Give the project a name. You can choose from a simple HelloWorld example or a slightly more advanced example using persistence and human tasks.
If you select the latter and click Finish, you should see a new project containing a “sample. ProcessTest” JUnit test class. You can open the BPMN2 process by double-clicking it.
To execute the process, right-click ProcessTest. The application server uses by default property files based realms – Please note that this configuration is intended only for demo purposes users, roles and passwords are stored in simple property files on the filesystem. As a result, the instructions below describe how you should configure a datasource when using JPA on JBoss application server e.
EAP7 or Wildfly10 using a persistence. The installer automates some of this like copying the right files to the right location after installation. By default, the jbpm-installer uses an H2 database for persisting runtime data. In this section we will:.
If you want to try this quickstart with another database, a section at the end of this quickstart describes what you may need to modify. There are multiple standalone. The full profile is required to use the JMS component for remote integration, so will be used by default by the installer. Best practice is to update all standalone. You might want to update the db driver jar name and download url to whatever version of the jar matches your installation.
For those of you who decided to use another database, a list of the available hibernate dialect classes can be found here. We need to change the datasource configuration in standalone-full. The original file contains something very similar to the following lines:. The installer already takes care of this mostly: it will copy the driver jar you specified in the build. Open this file and make sure that the file name of the driver jar listed there is identical the driver jar name you specified in the build.
Note that, even if you simply uncommented the default MySQL configuration, you will still need to add the right version here. Now would be a good time to make sure your database is started up as well! If you have already run the installer, it is recommended to stop the installer and clean it first using. If you decide to use a different database with this demo, you need to remember the following when going through the steps above:.
Change the name of the driver to match the name you specified when configuring the datasource in the previous step. Change the module of the driver: the database driver jar should be installed as a module see below and here you should reference the unique name of the module.
Since the installer can take care of automatically generating this module for you see below , this should match the db. You need to change the dialect in persistence. In order to make sure your driver will be correctly installed in the JBoss application server, there are typically multiple options, like install as a module or as a deployment. It is recommended to install the driver as a module for EAP and Wildfly. Install the driver JAR as a module , which is what the install script does.
Otherwise, you can modify and install the downloaded JAR as a deployment. Change the db. Note that this should match the module property when configuring the driver in standalone. Change the name of the module resource path to the name of the db. By default the demo setup makes use of Hibernate auto DDL generation capabilities to build up the complete database schema, including all tables, sequences, etc. This might not always be welcomed by your database administrator , and thus the installer provides DDL scripts for most popular databases.
See the section on timers for additional details. If you use MySQL 5. It would introduce further side effects.
For example,. Are you connected to the Internet? Do you have a firewall turned on? Do you require a proxy? If your download failed while downloading a component, it is possible that the installer is trying to use an incomplete file.
What if I have been changing my installation and it no longer works and I want to start over again with a clean installation? You can use ant clean. I sometimes see exceptions when trying to stop or restart certain services, what should I do? If you see errors during shutdown, are you sure the services were still running?
If you see exceptions during restart, are you sure the service you started earlier was successfully shutdown? Maybe try killing the services manually if necessary. Something seems to be going wrong when running Eclipse but I have no idea what. What can I do? Always check the consoles for output like error messages or stack traces.
You can also check the Eclipse Error Log for exceptions. Something seems to be going wrong when running the web-based application like the business-central. For all other questions, try contacting the jBPM community as described in the Getting Started chapter.
Business Central provides various sample projects that will help you in getting started with automating business processes. These are bundled together with the application and you can easily try them out by navigating to Design Projects and clicking on Try Samples.
This section shows the different examples that can be found in the jbpm-playground repository. All these examples are high level and business oriented. Click Design Projects.
If your current space contains at least one project, the Import Project option is available under the dropdown menu in the space menu bar. In the Import Project dialogue, enter the following information:. Authentication Options : If the target git repository requires authentication, you can specify the user name and password using the expanded dialog option. In this process, three departments that is the Human resources, IT, and Accounting are involved.
These departments are represented by three users: Katy, Jack, and John respectively. Note that only four out of the six defined activities within the business process are User Tasks. User Tasks require human interaction. The other two tasks are Service Tasks, which are automated and connected to other systems.
Finally, if the candidate accepts the proposal, the system posts a message about the new hire using Twitter service connector. Note, that Jack, John, and Katy represent any employee within the company with appropriate role assigned. Click Human Resources Kjar Example hiring. The asset list page contains the hiring. Click these assets to explore.
Notice that different editors open for different types of assets. Deploy creates a new JAR artifact that is deployed to the runtime environment as a new deployment unit. After successfully building and deploying your project, you can verify its presence in the Execution Servers tab.
Click Deploy Execution Servers to do so. When you Deploy a project from the Project Editor, it is deployed using the default configuration which means using the Singleton strategy, the default Kie Base and the default Kie session.
If you want to change these settings, you can make the necessary adjustments on the Settings tab for the specific project. Then, you will be able to set a different strategy, or use a non-default Kie Base or Kie Session. Once you saved your settings you can redeploy the project as a new Deployment Unit. Once your artifact that contains the process definition is deployed, the Process Definition will become available in Manage Process Definitions.
Click Manage Process Definitions. The Process Definitions section contains all the available process definitions in the runtime environment. In order to add new process definitions, build and deploy a new project. Most processes require additional information to create a new process instance. This is done through forms. For this project, fill in the name of the candidate that is to be interviewed. When you click Submit , you create a new process instance.
This creates the first task, that is available for the Human Resources team. To see the task, you need to logout and log in as a user with the appropriate role assigned, that is someone from the Human Resources. When you start the process, you can interact with the human tasks. To do so, click Track Task Inbox. Note that in order to see the tasks in the task list, you need to belong to specific user groups, for which the task is designed.
A zip file of examples can also be downloaded from the downloads page, containing various examples that can be opened in the Eclipse-based Developers Tools. Simply download and unzip the examples artefact and import into your Eclipse workspace.
This property is responsible for how the id value of NodeInstance instances was generated. Setting this property to true meant that the same strategy used in jBPM 5 was still used, even though this jBPM 5 strategy meant that NodeInstance ids were not unique.
BusinessCalendarImpl was updated to business. Update your code to reflect this change – from old value business. The jBPM engine executes business processes.
To define the processes, you create business assets , including process definitions and custom tasks. A KIE base represents all the assets in a business process. This level provides fine-grained control, but requires explicit declaration and configuration of process instances, task handlers, event handlers, and other jBPM engine entities in your code. You can use the RuntimeManager class to manage sessions and processes.
This class provides sessions for required process instances using a configurable strategy. It automatically configures the interaction between the KIE session and task services.
It disposes of jBPM engine entities that are no longer necessary, ensuring optimal use of resources. You can use a fluent API to instantiate RuntimeManager with the necessary business assets and to configure its environment.
You can use the Services API to manage the execution of processes. For example, the deployment service deploys business assets into the engine, forming a deployment unit.
The process service runs a process from this deployment unit. If you want to embed the jBPM engine in your application, the Services API is the most convenient option, because it hides the internal details of configuring and managing the engine.
Use public APIs in applications that you develop and maintain. A KIE base contains a reference to all process definitions and other assets relevant for a process. The engine uses this KIE base to look up all information for the process, or for several processes, whenever necessary. You can load assets into a KIE base from various sources, such as a class path, file system, or process repository. Creating a KIE base is a resource-heavy operation, as it involves loading and parsing assets from various sources.
You can dynamically modify the KIE base to add or remove process definitions and other assets at run time. When you use the KIE session to start a process, a new process instance is created. This instance maintains a specific process state. Different instances in the same KIE session can use the same process definition but have different states. For example, if you develop an application to process sales orders, you can create one or more process definitions that determine how an order should be processed.
When starting the application, you first need to create a KIE base that contains those process definitions. You can then create a session based on this KIE base. When a new sales order comes in, start a new process instance for the order.
This process instance contains the state of the process for the specific sales request. In most simple use cases, you can use a single KIE session to execute all processes.
You can also use several sessions if needed. For example, if you want order processing for different customers to be completely independent, you can create a KIE session for each customer. You can also use multiple sessions for scalability reasons. The KIE base includes all process definitions and other assets that your application might need to execute a business process. To create a KIE base, use a KieHelper instance to load processes from various resources, such as the class path or the file system, and to create a new KIE base.
The following code snippet shows how to create a KIE base consisting of only one process definition, which is loaded from the class path. This “manual” process of creating a KIE base is simpler than other alternatives, but can make an application hard to maintain.
Use other methods of creating a KIE base, such as the RuntimeManager class or the Services API, for applications that you expect to develop and maintain over long periods of time. You can use this session to start and manage processes and to signal events.
The following code snippet creates a session based on the KIE base that you created previously and then starts a process instance, referencing the ID in the process definition. The KieSession class exposes the ProcessRuntime interface, which defines all the session methods for interacting with processes, as the following definition shows. When working with processes, you might need to assign a business identifier to a process instance and then use the identifier to reference the instance without storing the generated instance ID.
A class that implements CorrelationKey can have either a single property describing it or a multi-property set. The value of the property or a combination of values of several properties refers to a unique instance. This interface exposes the following methods:. Correlation is usually used with long-running processes. You must enable persistence if you want to store correlation information permanently.
This class encapsulates and manages the KIE base and KIE session, as well as the task service that provides handlers for all tasks in the process. The KIE session and the task service within the runtime manager are already configured to work with each other and you do not need to provide such configuration. For example, you do not need to register a human task handler and to ensure that it is connected to the required service. The runtime manager manages the KIE session according to a predefined strategy.
The following strategies are available:. Singleton : The runtime manager maintains a single KieSession and uses it for all the requested processes. Per Request : The runtime manager creates a new KieSession for every request. Per Process Instance : The runtime manager maintains mapping between process instance and KieSession and always provides the same KieSession whenever working with a given process instance. Regardless of the strategy, the RuntimeManager class ensures the same capabilities in initialization and configuration of the jBPM engine components:.
KieSession instances are loaded with the same factories either in memory or JPA based. Work item handlers are registered on every KieSession instance either loaded from the database or newly created. Event listeners Process , Agenda , WorkingMemory are registered on every KIE session, whether the session is loaded from the database or newly created.
The runtime manager also enables disposing the jBPM engine cleanly. It provides dedicated methods to dispose a RuntimeEngine instance when it is no longer needed, releasing any resources it might have acquired. The RuntimeManager class also provides the RuntimeEngine class, which includes methods to get access to underlying jBPM engine components:.
An identifier of the RuntimeManager class is used as deploymentId during runtime execution. For example, the identifier is persisted as deploymentId of a Task when the Task is persisted. The deploymentID of a Task associates it with the RuntimeManager when the Task is completed and the process instance is resumed. The same deploymentId is also persisted as externalId in history log tables. That means your application uses the same deployment of the RuntimeManager class in its entire lifecycle.
If you maintain multiple runtime managers in your application, you must specify a unique identifier for every RuntimeManager instance. When you need to interact with the jBPM engine or task service from within a handler or a listener, you can use the RuntimeManager interface to retrieve the RuntimeEngine instance for the given process instance, and then use the RuntimeEngine instance to retrieve the KieSession or TaskService instance.
This approach ensures that the proper state of the engine, managed according to the selected strategy, is preserved. This strategy instructs the runtime manager to maintain a single RuntimeEngine instance and in turn single KieSession and TaskService instances. Access to the runtime engine is synchronized and, therefore, thread safe, although it comes with a performance penalty due to synchronization. This strategy is similar to what was available by default in jBPM version 5.
Use this strategy for simple use cases. It has a small memory footprint, with single instances of the runtime engine and the task service. In this strategy, because of the single KieSession instance, all state objects such as facts are directly visible to all process instances and vice versa. The strategy is not contextual. When you retrieve instances of RuntimeEngine from a singleton RuntimeManager , you do not need to take the Context instance into account.
Usually, you can use EmptyContext. In this strategy, the runtime manager keeps track of the ID of the KieSession , so that the same session remains in use after a RuntimeManager restart. The ID is stored as a serialized file in a temporary location in the file system that, depending on the environment, can be one of the following directories:.
Do not use this combination in production applications. This strategy instructs the runtime manager to provide a new instance of RuntimeEngine for every request. One or more invocations of the jBPM engine within a single transaction are considered a single request.
The same instance of RuntimeEngine must be used within a single transaction to ensure correctness of state. Otherwise, an operation completed in one call would not be visible in the next call. This strategy is stateless, as process state is preserved only within the request. When a request is completed, the RuntimeEngine instance is permanently destroyed. If persistence is used, information related to the KIE session is removed from the persistence database as well.
It is a good fit for high-load, stateless processes, where no facts or timers must be preserved between requests. In this strategy, the KIE session is only available during the life of a request and is destroyed at the end of the request.
When you retrieve instances of RuntimeEngine from a per-request RuntimeManager , you do not need to take the Context instance into account. This strategy instructs RuntimeManager to maintain a strict relationship between a KIE session and a process instance. Each KieSession is available as long as the ProcessInstance to which it belongs is active.
This strategy provides the most flexible approach for using advanced capabilities of the jBPM engine, such as rule evaluation and isolation between process instances. It maximizes performance and reduces potential bottlenecks introduced by synchronization.
At the same time, unlike the request strategy, it reduces the number of KIE sessions to the actual number of process instances, rather than the total number of requests. It maintains a strict relationship between KieSession and ProcessInstance to ensure that it always delivers the same KieSession for a given ProcessInstance.
It merges the lifecycle of KieSession with ProcessInstance , and both are disposed when the process instance completes or aborts. It enables maintenance of data, such as facts and timers, in the scope of the process instance. Only the process instance has access to the data. It introduces some overhead because of the need to look up and load the KieSession for the process instance. It validates every usage of a KieSession so it cannot be used for other process instances.
An exception is thrown if another process instance uses the same KieSession. EmptyContext or null: Used when starting a process instance because no process instance ID is available yet. Build a RuntimeManager instance and keep it for the entire lifetime of the application, as it is thread-safe and can be accessed concurrently.
Get RuntimeEngine from the RuntimeManager , using the proper context instance as determined by the strategy that you configured for the RuntimeManager class. After completing processing, dispose RuntimeEngine using the RuntimeManager. When RuntimeEngine is obtained from RuntimeManager within an active JTA transaction, you do not need to dispose RuntimeEngine at the end, as RuntimeManager automatically disposes the RuntimeEngine on transaction completion regardless of the completion status: commit or rollback.
The following example shows how you can build a RuntimeManager instance and get a RuntimeEngine instance that encapsulates KieSession and TaskService classes from it:. This example provides the simplest, or minimal, way of using RuntimeManager and RuntimeEngine classes. It has the following characteristics:.
The RuntimeManager class encapsulates internal jBPM engine complexity, such as creating, disposing, and registering handlers. It also provides fine-grained control over jBPM engine configuration. To set this configuration, you must create a RuntimeEnvironment object and then use it to create the RuntimeManager object. The following definition shows the methods available in the RuntimeEnvironment interface:.
To create an instance of RuntimeEnvironment that contains the required data, use the RuntimeEnvironmentBuilder class. This class provides a fluent API to configure a RuntimeEnvironment instance with predefined settings. The following definition shows the methods in the RuntimeEnvironmentBuilder interface:.
Along with empty instances with no settings, you can get builders with several preconfigured sets of configuration options for the runtime manager. The following definition shows the methods in the RuntimeEnvironmentBuilderFactory interface:.
