    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.

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