We have a Sun V1280 w/ 12 CPU's and 24G or RAM. It has Solaris 9 release
9/04 (s9s_u7wos_09 SPARC). I was looking at the system via the top utility
and I was wondering about a RAM usage. I don't think it's using RAM very
wisely and I wanted to get some opinions by some of the folks on this list.
The system is running Oracle and the HR application Peoplesoft. It has
several instances of both of them. The top command's output is listed
below.
The big question that I have is: Why would it be using 13G of SWAP, when it
has about 8.5 G of RAM free? Any thoughts? Any references on docs that
will explain memory management on Solaris better? Or even a better utility
than top.
Thanks in advance and I will summarize if I get an answer,
chuck
