Oracle required changes to the Solaris /etc/system file

Ever needed to install Oracle on Solaris, but can’t seem to find all that good stuff you have to add to the /etc/system file? I have, so here they are!

set maxusers 32
set shmsys:shminfo_shmmax=4294967295
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=512
set shmsys:shminfo_shmseg=128
set semsys:seminfo_semmni=512
set semsys:seminfo_semmsl=512
set semsys:seminfo_semmns=1024
set semsys:seminfo_semopm=256
set semsys:seminfo_semvmx=65534

  1. This is one of the first things you have to do if you are setting up Oracle on a Solaris box. Also keep in mind that these memory semaphore values may be different depening on how much RAM you have in your machine.

  2. You dont say wich solaris or oracle version.
    Since it is 2004 post, you certanly havent got Solaris 10 in mind. In Solaris 10, most of this settings are obsolete and you may end up with worse performance
