Dear all,

I check work_item table in db. I found about 1700000 records stored in this table and there is about 1400000 records with status = 32 i.e disabled , I think this huge number of records due to I use many subprocesses in process . My questions are

1-we face a problem in performance now. Is this huge number of records can cause problem in performance .

2- When I move from subprocess to subprocess . Many records with state disabled are crated in db for each user in WF. I don’t know why ?.

3- If I didn’t use cancel checkout() . is there any problem if I delete records with state disabled from db.

4- Is there any configuration to delete disabled workitems like cleanup server


Thanks

A large number of workitems in the disabled state likely means that you distribute your workitems to many people. A workitem enters the disabled state whenever another potential owner of the workitem either starts or checks out the workitem. For instance let's say we have 20 workitems for activity A (all would be in Ready state). User 1 checks out activity A, We now have 1 Item in Checked out state and 19 items in disabled state.

I do... you likely have the SubProcess Activity set to ALL people.

Can this affect performance... YES FOR SURE. Your models need to be fixed.
