Hello. We have an application which runs over night. It is failing some time on ORA-54 and I am trying to troubleshoot. I know that, we can use DDL_WAIT_FOR_LOCKS parameter to contorl if DDL statements wait and complete instead of timing out if the statement is not able to acquire all required locks. But I like to know - A. What controls the wait duration to acquire the required locks, before timing out? B. Can we set this wait time? Any input? Thanks, Shiva
