I am getting an error while performing the following steps:-

1. Login as Admin->Objects->Resource
2. Click in Audit Trail Tab->Move Date of Hire and Date of Termination columns to the right.
3. The Page keeps spinning for 5 mins and then throws 500 Error.
Reviewing the app-ca.log file, we found the following error message:

Caused by: java.sql.SQLException: [CA Clarity][Oracle JDBC Driver][Oracle]ORA-04021: timeout occurred while waiting to lock object

This means that another DB session already has a lock on the object.
Bouncing the DB Server resolved the issue.
