Jared, Tim and Anjo,

Thanks for your help.
In fact, I stopped the tracing first, then cp the trace file to other directory and rm it.
Also I can't trace other sessions now.

Tom,

The problem is that you moved the file.

Oracle will use the same file name, when you stop/restart tracing, and in fact leaves the file handle open until the session disconnects.

Moving the file disables the output.

        Subject:        How to re-trace a session

Hello,

I successfully traced a long running session by using dbms_system.set_ev procedure, and moved the trace file to somewhere else. However, when I used the same command to re-trace the same session, I can't see the trace file again. There was no error message. I tried to use oradebug and dbms_system.set_sql_trace_in_session to trace the same session. No matter what method I used, I still can't see the trace file. Then, I tried to trace other sessions using all available methods, but all failed. Even though there was no error message, I can't see trace files.

Can someone tell me what is wrong and how can I re-enable the sql trace?

Tom
