Here you go...

alter session set events '10046 trace name context off' END OF STMT
PARSE #1:c=0,e=2,p=0,cr=0,cu=0,mis=1,r=0,dep=0,og=4,tim=2447763926 EXEC #1:c=0,e=0,p=0,cr=0,cu=0,mis=0,r=0,dep=0,og=4,tim=2447763927

Oops! The the smart A$$ turned off the trace, But got caught!!!

Following is what you see in the trace file when the session is not tracing.....

Dump event group for level SESSION
TC Addr Evt#(b10) Action TR Addr Arm Life

I thank Ross for his nifty hints and his time last night, when I was having a 'brain fart' while testing this...

I learned something new from him... :)

Cheers!

You may turn the trace on or off that way, but how do you interrogate it to find its event settings?

ORADEBUG SETORAPID, would make "current session" whatever you like, no?

>From what I know, there is no way to find if a session has turned on the
tracing unless it is your own session. DBMS_SYSTEM.read_ev can you tell you if the current session is tracing or not, but it can not interrogate other sessions.

The only way I know is to check the trace files generated in the udump directory.. but it is not fool-proof.

And since you can not find out who is tracing at the moment, you can not stop it..

Ross, I sure would like to learn the trick. Can you please post it?? :)

Thanks.
