        Hi,

        If you open up task Manager on the server, and swap to the
performance tab,
        how much physical memory is shown as available?
        While you're on that tab, how much total physical memory does Task
Manager
        report?

        As per Jared's question, what do the following 2 queries show?
        select * from v$sga;
        select name , value from v$parameter where name = 'db_block_size';

        Regards,
        Bruce Reardon

        aaa aaa,
        ( if that's your real name :)

        Considering that your page faults are very high, take a look
        at the sizes of db_block_buffers, db_block_size, and
shared_pool_size
        for starters.

        512 Meg of RAM isn't exactly an overabundance, but will perform
        especially badly if you've allocated all of it ( or more ) to the
        shared_pool and/or buffer cache.

        We have HP server with NT 4.0 installed.  This server dedicate for
ORACLE
        use.  The ORACLE version is 8.1.5 (no patch installed). we found the
        performance NOT really good. I turn on the "performance monitor" and
found
        the "memory page fault" and "memory pages/sec" are very high while
SQL
        statement running (even only one user running).  The Server have
following
        configurations:

            HP LH 3000
            2 CPU
            500 Mhz
            512 MB RAM
            1200 swap space on C:
            ORACLE software and NT on C: (9GB, 7200RPM??)
            ORACLE data on d: (8 X 9GB RAID 5, 7200RPM??)
            ORACLE SGA 250MB

        Can anyone give me some hints why:

           1. page fault very high?
           2. SQL statement run very slow (I turn on TKPROF to trace and
found
        it is NOT ORACLE SQL statement inefficient problem)?

        Thanks.
