Deadlock Detection

All,

My current application (still under development) is experiencing Oracle deadlock problems. The applications people are performing stress testing where the application is being repeatedly called simulating actual users hitting the database.

The application is written using VB thru ADO and COM, Oracle 816 on NT.

My problem is that, while I can review the trace file produced, I can't figure out what the actual deadlock is occurring on. I have seen deadlock trace files that clearly state "table blah", but in this case, I get:

• 2001-06-21 14:32:03.841
• SESSION ID:(27.31211) 2001-06-21 14:32:03.810 DEADLOCK DETECTED Deadlock graph: ---------Blocker(s)-------- ---------Waiter(s)--------- Resource Name process session holds waits process session holds waits DX-0000003b-00000000 22 18 X 24 27 X session 18: DID 0001-0018-0000003C session 27: DID 0001-0018-0000003C Rows waited on: Session 27: no row
• 2001-06-21 14:32:03.857 ksedmp: internal or fatal error ORA-00060: deadlock detected while waiting for resource

Is there something like TKPROF that will process the trace file and give me more info on what is happening? It looks like I am waiting for a resource to be freed, but which one is the question.

thanks for any help.
