Script to find the Concurrent Request ID from its associated SID

Question

Hi,
In one of my production system, my server load is going very high. From the top used process ID of server, I found the SID and found out that the program running is "ora_rw20_run@acgerp (which is a concurrent program)
How do I find out the Request ID using the SID/PID? Can someone please provide me the script to find the Concurrent Request ID from its associated SID?
Thanks!

Answer 1

There has been no new changes in the report server or in the database. Suddenly of late, we have been observing this program running and it never ends, consuming major part of the cpu load. Not sure what this program is -> ora_rw20_run. There is no mention about it in metalink or in google.
I followed MOS Doc 1058210.6 and tried to debug more. But the formatted output doesnt give any info either.

When I use the below query, I can find that the session is running a module named "PAXMGSLS" and the action is Concurrent Request.
But I am not sure how to find out the Concurrent Request ID using this info to dig more (look into the concurrent request log files etc)
select s.sid,s.serial#,p.spid os_pid,s.status,
s.osuser,s.username,s.COMMAND,s.MACHINE,s.MODULE, s.SCHEMANAME,
s.LOCKWAIT,s.action
from v$session s, v$process p
WHERE s.paddr = p.addr
and s.sid = 823
