"Re: Is SessionID & ProcessID required to complete WorkItem ?" To view the discussion, visit: https://community.jboss.org/message/732798#732798 -------------------------------------------------------------- Hi Vikas, I have been using JBPM 5.2 in a similar environment. My understanding is as follows - Session ID: The session is a global repository where you store common data across processes. This comes into play only when you are using Rule (Which is why is is a knowledge repository). If you are using JBPM purely for execution of workflow (i.e. just graph execution), the JBPM session ID is not of much relavence. I would still recommend you use the same session ID to complete a work item (Just to keep the JBPM data consistent). - Process ID - This is a unique ID for each process instance. The nodes execute in the context of a process. Hence this is of relavence. When you complete a work item, the work item id is sufficient. This is because, the work item Tables in JBPM DB have a reference to the Process instance id. hence this is known to JBPM. - Work Item ID : Self explanatory i guess. Regarding how KSession works in a clustered environment. There are multipe approaches to this. What i have opted for is to use a separate KSession for each process instance. (Purely because i do not use any rules). Other approaches i have come across in the forums are to use a specific KSession for each server instance in your cluster. All processes that execute in a server will use the same ksession. Their process instances will be different. The approach you take should be based on how you are using JBPM. Happy working.. Its always hard for the first few who start using a new Technology. But i am sure its worth the effort :) Cheers ! -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/732798#732798] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034]
