Home -> Community -> Mailing Lists -> Oracle-L -> Process field on v$session
All,
For a good chunk of the day now, I've been trying to get all information I can about this one session that is consuming up to 70 per cent of CPU on our db server.
Let me give you a little background: We have an application server that
runs a web-based system for class registration. This app server runs
Apache. The task mingler on this app server shows several Apache PIDs
-each db instance has its own separate web service and in turn, each
Apache PID can have several child processes.
Now, in my efforts to track down this CPU-hogging session; on our db server I see this session as coming from the app server [get this from v$session.machine.] I can also get some other goodies by joining on v$process to get the db server PID. I've done pretty good up to this point, but there is one field on v$session called 'process' of which I am uncertain. This field shows two numbers separated by a colon (e.g. 2800:2168). A little bit of research indicates that the first number corresponds to the app server Apache's PID. I have used netstat on my app server to see if the second number would be a port number. But, netstat does not show any clients connecting to that port number. Has anyone figured out what that second number stands for? Is it a client's identification number of some sort or is it just a random number generated by Oracle upon establishing a connection? I'll appreciate any input you may have on this. Thanks in advance!
Julio
