help with vmstat output
Hi all.
I need some assistance with my vmstat output.

We have several oracle db's running on our solaris machine:

SunOS rcworaprd 5.9 Generic_112233-07 sun4u sparc SUNW,Sun-Fire-480R

Recently I bumped up our main Oracle database to use 6 GB instead of 4 GB as vmstat output was showing I had over 5 GB free memory... After I completed that I noticed swap space dropped to about 60MB free but free memory didn't. I kind of assumed that the free memory would drop 2 GB but it stayed the same. I added a swap file of 1 gb and now swap free shows 900 MB.

Can anyone give me some detailed instructions on what I should be looking for in my vmstat output. I'm pretty new with Solaris admin.

Thanks

Here's a smaple of my current vmstat output:

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris  invokes  the  Solaris  Install  program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

           Minimum physical memory for all installation types

       128 MB

           Minimum physical memory required for windowing system

       384 MB

           Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

           Minimum physical memory for all installation types

       256 MB

           Minimum physical memory required for windowing system

       512 MB

           Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris  exists  only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.
