Hi

I installed Oracle 10.2.0.2 on a Sun Solaris Box 2 weeks ago and I noticed last Monday by running ipcs -a that the shared memory segment arent using the value I have configured, 4GB.

I thought I have to use Solaris 10 new resource control so I proceeded to configured it and still ipcs -a shows small memory segments. I was wondering if there are more steps in Solaris 10 to increase shared memory? I have googled but seems that what I did was enough!

Thanks

Alex

From /etc/system:

set shmsys:shminfo_shmmax=4294967295
set semsys:seminfo_semmni=256

From resource control:

$ prctl -i project group.oinstall
...
project.max-shm-memory

        privileged 4.00GB - deny
-

        system 16.0EB max deny
-

....

ipcs output

$ ipcs -a
