Solaris 2.x systems run with a lot of memory (both real and swap) allocated when the processes are launched. This improves overall system performance since the OS is pre-emptively guessing memory demand rather than reacting to requirement.

It is usual to see an Oracle process allocate a sizeable chunk of both real and swap. Received on Fri Apr 30 1999 - 05:37:37 CDT
