Symptoms

When starting an Oracle instance all of the SGA memory is allocated on swap space, even though there is plenty of free physical memory available on a Solaris server.

Changes

The SGA_MAX_SIZE, MEMORY_MAX_TARGET, or MEMORY_TARGET parameters have been set in the instance to enable Automatic (Shared) Memory Management (AMM/ASMM).
