Well... you can start by providing what is the total system memory and
what is the total SGA of your database?

This will ALWAYS be the case when Oracle runs on Solaris after a short
period of time after a reboot & users are using the DB. It does NOT
matter how much RAM you put in the system or how small you make the
SGA.

Simply put "free memory" is a useless indicator of anything.
A better metric is the Page Scan rate;
where 0 is GREAT
and < 10 is perfectly acceptable
and < 100 should be of no concern
and > 1000 users will like experience slow response time.

If you have a "top" utility on the server can you paste the "top"
output and your hardware and software configuration.

Thanks.
