Pinned topic SVMON -G, SVMON -U mismatch

‏2013-01-07T14:38:21Z |
Hi,

Have 2 LPAR database servers AIX 6. Both machines have 70GB of RAM

nmon and svmon -G both show circa 66GB of RAM in use.

svmon -U for all users only shows circa 41GB in total use.

Main user is oracle and svmon -U figure here tallies against total memory in use by oracle databases.

can anyone suggest what is causing the mis-match and / or how to drill down further.

Unit: GB

    As I understand it the difference is taken up memory used for file system cache.
