Hi There,
This is the Task Persistence database in derby that our IAM Framework uses to track tasks (Create Domain, Modify Rule, Delete Policy, etc.).
These files cannot be deleted (or you will get unexpected behavior) , but the tables can be cleaned up through the Admin UI as below :
Run Cleanup Submitted Tasks
----------------------------------------
1. Login to the Siteminder Administrative UI as the Siteminder Administrator
2. Go to the Cleanup Submitted Tasks UI under Administration->Admin UI
3. Select "Execute now" and select "Next"
4. Select the "Minimum Age". e.g 30 Minute
5. Select "Finish"
(This may take a while if there were a lot of rows in the database tables that needed cleaning up.)
6. Check the disk space under <CA SSO Install>/adminui/server/default/data/derby/siteminder/taskpersistence.
The amount of disk space should be reduced as compared to before the Cleanup Submitted Tasks run.
7. You can repeat step 3-6 and at each iteration select longer duration, until the size of the files reduces considerably.
You can also choose to schedule a recurring job to perform automatic cleanup.
If the above steps do not help, you can also choose to considering deleting the data folder all-together and re-register Admin UI.
Hope this helps
Cheers,
