sqlnet trace in ProC app

Platform: Oracle 9204, ProC application, AIX433

I need a SQLNET trace from a Proc app. This is normally done by updating the sqlnet.ora file. We are having a application problem which might be a network problem and need to trace sqlnet. We have successfully traced sqlnet on the server and on the client using sqlplus. However, when we have the sqlnet.ora set for tracing and run our ProC application, no trace files are produced. So I was wondering if, for ProC apps, the sqlnet.ora is read at compile time vs, runtime. Or if there is some precompiler option to turn on tracing. I have searched documentation on this issue and cannot find anyting that says ProC apps are any different in this respect. I was wondering if anyone out there with real world experience has done this. Oracle says that for ProC apps, it is the same, it reads the sqlnet.ora at connect ime. But then why am I having this problem. I have one sqlnet.ora file on my server that is acknowledged when I connect through sqlplus, but no when I connect through a ProC app.

Thanks a lot for any suggestions and advice.

Did you change the correct sqlnet.ora and the following parameters:

TRACE_LEVEL_CLIENT = 16
TRACE_FILE_CLIENT = cli.trc
TRACE_DIRECTORY_CLIENT = <path>

I have successfully produced sqlnet trace files by setting these parameters.

Note that in some installations, sqlnet.ora is found in the environment variable TNS_ADMIN.  Find out the location of sqlnet.ora using this env. variable.
