Dear Sun Gurus,
I am concerned about my swap space because it does not
appear that it is being used. It was working before I
installed Oracle and modified /etc/systems. This is
on an Ultra Enterprise 250 running Solaris 8. I
previously had about 1 GB of Swap with 1 GB of RAM.
My NIS+ seemed to eat up a lot of the swap until I
added another 2 GB of swap, which fixed the problem of
not being able to checkpoint the NIS+ DB. A couple of
weeks later I modified my /etc/systems and added the
following:
set shmsys:shminfo_shmmax=4294967295
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmseg=10
set shmsys:shminfo_shmmni=100
set semsys:seminfo_semmns=1000
set semsys:seminfo_semmni=100
set semsys:seminfo_semmsl=256
Installed Oracle and now my swap space is not being
used. See swap -l and vmstat below:
swap -l

Here is a copy of my /etc/vfstab:
cat /etc/vfstab
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options

yes -

Can anyone tell me what might be going wrong?
Thank you for your time.
Bob
