It really isn't as complicated as people are making it.
If your experiencing excessive paging and swapping like you said, get a verification report from the output of commands like iostat, vmstat, sar -wpgr 5, ps and then send it to the person in charge of adding memory to the system. Have him study the report and determine if a memory upgrade is needed.
If you find out that the excessive swapping or whatever problem your having is because of memory shortage, you might wanna try a few things (for the main time) before deciding to buy and install new memory. I suggest you take a good look at ps and find out the processes that take up a lot of memory or processes that accumulate a lot of time. Contact the Users who owns this processes and ask if you can reschedule the processes to run at a later time when the load on the system is light. Or you can ask the user if you can renice the job to run at a lower priority.
Thats all there is to it, my man.

This might sound silly but i am trying to determine if i have sufficient memory or not.

apache::session::oracle
Apache::Session::Oracle(3pm) User Contributed Perl Documentation Apache::Session::Oracle(3pm)
NAME
Apache::Session::Oracle - An implementation of Apache::Session
SYNOPSIS
use Apache::Session::Oracle;
#if you want Apache::Session to open new DB handles:
tie %hash, 'Apache::Session::Oracle', $id, {
DataSource => 'dbi:Oracle:sessions',
UserName => $db_user,
Password => $db_pass,
Commit => 1
};
#or, if your handles are already opened:
tie %hash, 'Apache::Session::Oracle', $id, {
Handle => $dbh,
Commit => 1
};
DESCRIPTION
This module is an implementation of Apache::Session. It uses the Oracle backing store and no locking. See the example, and the
documentation for Apache::Session::Store::Oracle for more details.
USAGE
The special Apache::Session argument for this module is Commit. You MUST provide the Commit argument, which instructs this module to
either commit the transaction when it is finished, or to simply do nothing. This feature is provided so that this module will not have
adverse interactions with your local transaction policy, nor your local database handle caching policy. The argument is mandatory in order
to make you think about this problem.
This module also respects the LongReadLen argument, which specifies the maximum size of the session object. If not specified, the default
maximum is 8 KB.
AUTHOR
This module was written by Jeffrey William Baker <jwbaker@acm.org>.
