PL/SQL lock timer

edited Jun 13, 2011 3:04AM in Database Tuning (MOSC) 4 commentsAnswered

I found in one of the trace file as below PL/SQL lock timer  is taking 644.58 seconds in the database.

Could you please look into this and let me know the reason for this?

 Elapsed times include waiting on following events:
  Event waited on                             Times     Max. Wait  Total Waited
  ----------------------------------------             Waited    ----------      ------------
  PL/SQL lock timer                           132        4.90        644.58
  SQL*Net message to client                    1        0.00          0.00
  SQL*Net message from client                 1        0.04          0.04
