Can we set an event to trace pmon for,
1)dump last activity when ever a client/user closes abnormally and pmon have to do cleanup.
2)Dump rollback/undo information when ever pmon has to rollback transactions as the client/user lost connect with out issuing a commit or rollback.
I tried the following events but none of them give the information I am looking for....
#Event 10246 to Trace PMON Process
#Event 10012 to Monitor Abort Transaction
#Event 10013 to Monitor Transaction Recovery
#Event 10015 to Dump Undo Segment Headers
regards,
Kaz

I am looking for the last statement executed (or transaction recovery by pmon if any) by a user when the client application (not the server session) crashed.
thx.

The statement/transaction is nowhere. You can't have this information.
PMON does not need to know the statement to rollback it.
By the way, PMON does not rollback a statement but a transaction.

Michel,
I understand PMON does not rollback a statement but a transaction. I might not have put it the right way.
So its not possible to dump the last activity of a user when the client application crashes or the connection closes abnormally.
thx.

You can know it mining the logs but not with PMON activity.
Of course you can know nothing about select statements.

Sometimes we have app server crashes, and I just wanted to know what was the last activity by that session, so it seems we can't get that information.
thx.
