The administrator on our ERP system is concerned that we may be getting
table locking problems (where a process has to wait until a row lock is
released by another process). We have recently received ORA-00060 errors
(the one where Oracle inserts the text "The following deadlock is not an
ORACLE error. It is a deadlock due to user error in the design of an
application or from issuing incorrect ad-hoc SQL"). We believe the ORA-00060
is due to a specific program error.
However, she is concerned that we may be receiving other table locks
and not know it. I have run STATSPACK quite a bit, and haven't seen any
waits that look like this, but maybe I'm not looking for the right thing. I
have been monitoring the "User Type Locks" screen in OEM, but that is just
the momentary events
- If we were getting table locks (where a process has to wait until
another process releases what specific wait event would show up?
- Assuming we are receiving table lock waits, is there a way to
accumulate waits by table to help us debug the issue?
Any thoughts would be appreciated.
