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:

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

Thanks.
