Here you go...

1. Find the OSPID for the suspected user (other than pmon, smon and their famiy)

select s.username, p.spid
from v$session s, v$process p
where s.paddr = p.addr;

2) Use oradebug to connect to that spid (here I have 26073, and the session was tracing event 10046)

SVRMGR> oradebug setospid 26073
Oracle pid: 11, Unix process pid: 26073, image: oracle_at_myservername (TNS V1-V3)

3) Dump the events for the connected spid...

SVRMGR> oradebug dump events 1
Statement processed.

4) Look in the trace file in the udump directory..

  • 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!

OR

It would seem this approach will only work for the current session

Hi Walt -

Kinda getting into this myself recently. I found a reference to an undocumented dbms package on Metalink today called: dbms_system.read_ev

I'm playing around with their test scripts to see what I can do with this in conjunction with v$session and tracing and auditing. Check out notes 1020308.6 and 28446.1

Hope this helps.

I'm looking for a way of checking which sessions on the database have trace turned on. I can set event in another session, but I'd like to know whether the event (10046 in this case) is set in some sessions.
