No shared memory for Oracle with ipcs under Solaris ?

Hello,

I'm trying to find the memory size of some oracle instance . With aix i do this with svmon + ipcs .

The Solaris equivalent to svmon seems to be pmap, so the logics seemed to be
similar.

But when i run the ipcs -mA command, it shows no shared memory for oracle. Some shared memory is shown, but none for the oracle user !

What does it means ? Is the size of memory segments as shown with pmap displaying the total reserved size for that segment ? Why is there no trace of oracle with ipcs ?

Also AIX has an option to ipcs ( -S ) that will show the list of Segment ID attached to a shared memory id. This way you can track back shared memory information to VSID and in turn to PID . This is usefull because the sized shown for a VSID of shared mem is the in-use size and
with ipcs you can see the max reserved size, therefore aproaching the corect maximum memory size for an instance .

Does someone knows how to do this with Solaris ? Do you know of other ways to compute the memory size of a given oracle instance from within Unix ?

The setup is Solaris 5.8 and Oracle 9 . It should be noted that i'm not
root on the server, but i don't think that would change anything to the
ipcs output.

Thanks a lot if anyone can help or provide me pointers to info ,

Regards,
