How can I synchronize directory service and bpm engine?

Question

hi,all
I'm using bpm WL 10.3.1 with papi.
Now I want to assign role to participant in process.
I use DirHumanParticipant.setRolesAssignment() and DirHumanParticipant.update() to assign role dynamically.
But it does not work.
Actually, when I log in to the webconsole. The role has assigned to the participant.
but when I log in to the workspace. I cannot find expect task in my work items.
In the history view I can find it.
Then I remove the role that i assigned previous and assign again in the webconsole.
After that I log in to the workspace, now i can get the expect task in my work items.
I think it need to synchronize between directory service and bpm engine. but I don't how to do it?
Is there any way to do it with some api?
thanks
regards

Hi!
Here is how it works:
1. The engine polls the directory periodically and checks if some changes were made to the participant role assignments.
The poller frequency is configured on the Process Administrator.
2. When a change is detected, the engine updates the information on the engine partcipant cache.
However, if the participant is logged it, the update operation is postponed until the participant logs off.
3. After checking the directory, the engine directory poller sends a notification to all the PAPI clients (including the Workspace)
and the workspace side poller updates the participant assignment you see in the workspace.
The notification mechanism is using the JMS Topic on the JEE version of the BPM.
- First of all verify you are logged out when you add/remove the role.
After that, wait 1 minute or the time specified in the Process Admin as the directory poller frequency.
- Verify the JMS Topic is defined correctly. Check the engine log for any JMS Topic related error.
Hope it helps.
