Admins,

        We have a GS140 6 cpu's and 20 GB of memory running oracle 8.1.7.4
with SGA set to 11 GB. When executing ipcs -b, shared memory adds up to 11
GB however when executing a vmstat -P it is showing about 2000000 free pages
( approx 16 GB free ). This does not seem consitant to me. Could anyone
point me in the right direction as to why my shared memory adds up to 11 GB
and I have 16 GB free. I will summarize.

TIA,
