RE: Which process is taking up so much CPU???

        I just found that v$session.paddr = v$process.addr is the join that has to be done. Right?

        Dennis, you seem to be have a master in Oracle! please can you help, I can see the SPID column under table v$process, but how do I link it to table v$session so that I actually know which UNIX process it corresponds to. I think there must be another table that links both of them; you talk about the shadow process, where is it or where can I get more info on it.

        Thank you for your time.

Fermin.

   The spid column in the v$process column matches the Unix process i.d. You may need to track it back through the Oracle shadow process.

        I usually track our HP-UX 11.0 system with the 'top' command so I can notice when the system is under slow performance. If that happens, I use Toad to look for any active Oracle SQL query which may be heavy enough for degrading the performance.

        I think my question is simple, but since I am a newbie on this... how can I see who is executing an Oracle SQL that is taking all our CPU provided that I only see his PID with the TOP command? I only see the oracle process, but I don't know how to get the username and the SQL beside him.

        Thank you for your answers!

Fermin.
