Thanks James and John. The PL/SQL, developed in-house (not Oracle Apps), is called from a batch job which runs a script. The script doesn't loop, but the PL/SQL does ... through all order_lines for a specified order_release_id. I just didn't understand why consecutive "APPNAME mod=" lines would be emitted in the trace. I've had a heart-to-heart with one of our support analysts. Standards (established for good reasons) led to the use of SET_MODULE. For this particular batch job, *every* procedure and function call registers and de-registers the module or action. Functions are called during assignment operations. The trace file doesn't show assignments (may level-12 would?), so it was not really obvious what was calling SET_MODULE. I'm having a little trouble with calculating how much this contributes to response time, but I'll review Cary/Jeff's book tonight. Some time seems to be missing, but I hope to pinpoint that tonight.

In that case, is this from a Concurrent report? You may not be able to see the SET_MODULE as the wrappers around the Concurrent report may have set this....

If yes, is that code being called from outside of Oracle (some scripts or GUI program)? Maybe the calling program loops around the call to the PL/SQL code?
