RE: explain plans for PL/SQL and transactions

In a large number of cases, problems with PL/SQL are fully diagnosable with 10046 data. In the cases where non-db call activity is the response time problem, the 10046 data will show high "c" times for EXEC db calls on PL/SQL blocks. To drive into the details on these issues, you can use DBMS_PROFILER, which Tom Kyte explains in good detail on p475 and pp1161-1171 of his "Expert One-on-One Oracle" book.

Darrell,

His point is that 10046 does SQL tracing, not pl/sql tracing. OP asked for pl/sql tracing.

So, what's your point?

Patrice asked about tracing PL/SQL, not SQL.

Sounds like a good use for a 10046 level 8 or 12 trace. Full and recommend use of 10046 trace is too much for one e-mail but I'd start researching on metaling and there are some excellent documents available
at www.hotsos.com.

I like explain plan very much, but am looking for something similar that
covers PL/SQL as well.

A user here is submitting code that keeps looping. The SQL itself is not
the problem, I think the problem has to do with the execution path of the
PL/SQL code.

I am looking for something that provides the comprehensive info we get from
explain plan, but for a batch job.

Patrice.
