[jBPM] - Re: jbpm 5.3 - kSession.dispose() - Error: Session was previously disposed

Make sure that the dispose will happen after transaction completion.

When I open "Called Element" in the properties tab I can only see processes of the default package: https://community.jboss.org/servlet/JiveServlet/showImage/2-724922-18228/... https://community.jboss.org/servlet/JiveServlet/downloadImage/2-724922-18... although there are processe in my package: https://community.jboss.org/servlet/JiveServlet/showImage/2-724922-18229/... https://community.jboss.org/servlet/JiveServlet/downloadImage/2-724922-18... Do the subprocess have to be in a different package then the process who is calling them? Thank you!

[jBPM] - jbpm5 scale out reference architecture..

by Affan Dar

Affan Dar [https://community.jboss.org/people/affandar] created the discussion "jbpm5 scale out reference architecture.." To view the discussion, visit: https://community.jboss.org/message/717611#717611 -------------------------------------------------------------- After scavenging the forums and docs for jbpm 5 over the last week, I have drafted up the attached 'reference architecture' for a scalable jBPM 5 deployment. Would love to get feedback (aka ripped apart :) ). Here are the key pieces: 1. A shared KnowlegeBase which acts as a repository of processes across the whole deployment (master-slave replicated with writes-to-master and reads-from-slaves etc etc) 2. There are a fixed number of KnowledgeSessions spread across DBs in a DB farm (DB1, DB2) 3. A table contains the mapping between these sessions, the database that they are stored in and the node that is assigned to these sessions. Management of the data in this table is an admin config operation (either automatic or manual). 4. A number of worker nodes which load the KnowledgeSessions that belong to them (as per the table above) 5. Another table that has mapping of processes-to-sessions. This table is updated by the worker nodes when a new process is created. 6. A router or client proxy that routes process instance managment requests as per the following rules: - For process instance creation requests, round robin to any node - For requests pertaining to a specific process instance, consult the table in (5) & (6) and route to appropriate node Now how to scale out: - If the bottleneck is the CPU/memory of the worker nodes then add more nodes and rebalance the session distribution in table (3) - If the bottleneck is the DB capacity or disk then add a database, migrate processes/session data to the new database and update table (3) Of course the resharding above is crude and manual and can probably be more sophisticated but would love to hear thoughts/comments on the basic idea. Also practically speaking, I hope it is possible to migrate a session and processes to a different DB at all? Thanks -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/717611#717611] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

by new bee

new bee [https://community.jboss.org/people/newbird] created the discussion "Restore JBPM session" To view the discussion, visit: https://community.jboss.org/message/750414#750414 -------------------------------------------------------------- Hi, I am new to JBPM and struggling to understand the flow............. I red that we can store jbpm session,process instance,task instance and variables...etc............... After some point, assume application crashes and want to restore all running sessions how would i do? Do i need to get each process id/session id from the session and again start it? If i do in the above way, from which point it will start the session like it already proesses two nodes....How it will know to start from node3? Do i need to configure that also. If how would i? Also red in discussions that after restoring the session, we need to again register action handlers? Is it true? What is the use task server ,task service and task client? How they are different from workitem handler? Please reply............................................. :-/ -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/750414#750414] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - Re: Restore JBPM session

by Thomas Setiabudi

Thomas Setiabudi [https://community.jboss.org/people/thomas.setiabudi] created the discussion "Re: Restore JBPM session" To view the discussion, visit: https://community.jboss.org/message/752944#752944 -------------------------------------------------------------- I think the process should continue from before application crash point. Lets take the com.sample.evaluation included in the jbpm5.3 full installer. First step, we initiate the process instance lets say we pass in krisv as the employee name Second step, krisv look at his task list and then complete his task Third step, john look at his task list and then complete his task Fourth step, Mary look at her task list, but when she tries to complete her task, application crash. so we stop everything and restart After restart, Mary should be able to see the task in the task list and complete it. Isn't that the default behavior right now? Or do I misunderstand your question?

What is the maximum load the single instance of gateIn supports? I mean the number of concurrent requests supported by GateIn? 2. Is gateIn supports clustered environement? 3. Is there any server monitoring tool like Memory utilization, session management, each porrtal application memeory utilization as part of the out of the box. 4. How many documents can be accessed through users at a time? (no of document by no of users in 1 sec?) 5. CPU utilization under 1 lac users. Any extra information will be acceptable. Thank You very much in advance. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/784904#784904] Start a new discussion in JBoss Portal at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]
