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.

very slow ??
10/24/01 09:25 AM
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.
