There's some low level tracing in the sqlnet communcations area that you can look at enabling.

A couple of questions ... are you seeing errors in the alert log perhaps on the server when this is occurring? Is there a more experienced dba in your environment that can be of assistance perhaps?

FYI I tend to pass almost all trace files thru orasrp ( a resource profiler ) which when you execute it with a " --sort=crsid " will sort in the order that statements actually are in a trace file ... may not be terribly relevant to what you are doing now though.

I would expect to see a PARSE in cursor followed up by an EXEC and perhaps an ERROR in the situation that you are describing but well it's been a long time since I looked at a raw 8x trace file. Received on Wed Apr 09 2008 - 15:42:45 CDT
