Oracle-L: 10046 tracing in PRO C programs?

We're examining performance of a PRO*C program supplied by our software vendor and I'm looking at how I can get it to generate a 10046 trace file. There is a section in the code that allows the program to be executed with a trace flag set and this code section then runs:

EXEC SQL ALTER SESSION SET SQL_TRACE TRUE; I replaced this with these statements to setup the session for a 10046, level 8 trace:

EXEC SQL ALTER SESSION SET TIMED_STATISTICS=TRUE; EXEC SQL ALTER SESSION SET MAX_DUMP_FILE_SIZE=UNLIMITED; EXEC SQL ALTER SESSION SET TRACEFILE_IDENTIFIER='APPCODE'; EXEC SQL ALTER SESSION SET EVENTS '10046 TRACE NAME CONTEXT FOREVER, LEVEL 8'; The program compiles and runs and the program execution produces a trace file, however, the trace file contains only the text:

TRACE DUMP CONTINUED FROM FILE ***

No other information appears after this.

What's this all about? And, what is the best way to run a 10046 trace on a proC program? This program runs in a nightly batch job, so I really want to start the tracing within the program rather than start tracing from another session.

Thanks for any tips,

Glenn Stauffer
