Hi all!
Oracle 8.1.7 on AIX (8GB RAM (+ swap space 9GB)).
It concerns AIX memory 'problem'.
When I issue vmstat command, we got following result:
/u01/app/oracle/product/8.1.7.>vmstat 2 4
kthr memory page faults cpu
----- ----------- ------------------------ ------------ -----------
r b avm fre re pi po fr sr cy in sy cs us sy id wa
0 0 580556 554 0 0 0 14 34 0 126 137 63 11 5 82 1

0 2 580557 548 0 0 0 0 0 0 637 111 35 0 0 99 0
Analysing this output, it seams that we have cca 2GB RAM (example: (580557 +
548)* 4096 = 2,2 GB), while we expected min 8GB.
This gap between 8GB and output from vmstat report, increases in time.
The question is if our calculation was right, is this the right way to
analyse this at all?
Maybe it is important to say, that our Oracle is installed on OFA using data
files, max size 2GB, in same volume group(not on raw devices).
Do you know of any AIX memory problems which can manifests as mentioned
above?
TIA,
Sonja
