ORA-31635: unable to establish job resource synchronization

What triggered the Error:

A lock used in synchronizing Data Pump resources during job creation and deletion could not be obtained during job creation. This indicates that a process for some other Data Pump job has not released the lock due to an internal error.

What should we do to fix it:

Eliminate the processes for any failed Data Pump job and try to create the new job again. If the error continues to occur, contact Oracle Customer Support and report the error.
