Hi Tim
Could you
possibly Share the HPUX Custom Built script please?
Thanks indeed
Vivek
Anurag,
I have this shell script named "oramem.sh" posted online at http://www.EvDBT.com/tools.htm.
It was originally written for Solaris using the excellent "pmap"
utility. It can work with Linux if the SYSSTAT rpms are installed,
which
include "pmap". I have an alternate version for HPUX that uses
some custom-built "C" programs. I don't have a version for AIX
at all, as I haven't found anything similar to "pmap" on AIX.
Hope this helps...

Hi All,
My 9.2.0.7 database has an sga size of
1.3 GB and
the RAM size is 4096 MB.
We were facing a problem of memory contention yesterday due to the
increased
number of sessions/connections to the database.
96% of the Physical memory and 94-95% of virtual memory was used, when
checked
the processes in the IBM AIX server.
So when the number of sessions increased, listener stopped receiving
newer
connections.
The ever increasing number of sessions were taking up the memory.
Latch free contention was there and found library cache latch stats
were
showing large number of sleeps.
If we need to increase shared pool, memory was not available.
One option we are planning is to increase the physical memory.
So my question is how do we determine the size of the memory used for
Oracle
sessions.
Say for adding another 100 sessions, how much memory will it take, so
that it
will help us in adding more RAM in to the server.
Thanks for your thoughts on this.
Anurag
