Dear DBAs,
We have recently migrated Oracle from 8.0.6 on HP-Unix to
10.2.0.4 on Red Hat Linux
Earlier the same application worked fine with 7GB RAM on HP-UNIX
on PA-RISC
Upgraded system on IBM X 3850 with 16GB RAM but still we have
some performance issue.
I knew there is some lagging because of Hardware Architecture
but it is too bad 7 GB to 16GB RAM but still have performance.
Please look at data collected from RDA. Looking at this scenario
my physical memory is fullly used but Swap is not at all used.
Total Physical Memory 16032 MiB
Available Physical Memory 30 MiB
Swap: Max Size 24575 MiB
Swap: Available 24505 MiB
Swap: In Use 70 MiB
We know there is some performance issue in application. I would
like to make as much as possible from Database/Linux side tunning to
provide atlease peaceful performance. Can any body through some light on
why the swap is not at all used.
Regards
Mudhalvan M.M
