The amount of pinned pages it's reporting is changing all the time so I
don't think it's reporting a fixed page tables size or any similarly
fixed kernel parameter setting. The output from ipcs is below. The
fact that there are only 2 shared memory segments owned by Oracle and
they match the size of my two Oracle SGAs (production database and the
recovery catalog) makes me more comfortable that the high pinned pages
are not the result of old Oracle SGAs not being released.
Thanks,
Brandon
