Solaris

Hi All,

How do I manage swap memory of solaris 8-9-10 with oracle application? Is it separate management with system and application?

Any idea or links will do or books recommendation.

Thanks in advance.

The other option is to create a default project for the oracle user.

# projadd -U oracle -K \
"project.max-shm-memory=(priv,4096MB,deny)" user.oracle

What this does:

Makes a project named "user.oracle" in /etc/project with the user oracle as it's only member.
# cat /etc/project

system:0::::
user.root:1::::
noproject:2::::
default:3::::
group.staff:10::::
user.oracle:100:racle:roject.max-shm-memory
=(priv,4294967296,deny)

Because the name was of the form "user.username" it becomes the oracle user's default project.

The value of the maximum shared memory is set to 4GB, you might want to use a larger value here if you have more memory and swap.

No reboot is needed, the user will get the new value
at their next login.
Now you can also modify the max-sem-ids Parameter:

# projmod -s -K "project.max-sem-ids=(priv,256,deny)" \
user.oracle

Check the Paramters as User oracle

$ prctl -i project user.oracle
