Memory Bottleneck issue

[Jestin John Chacko]

Hai ...

One of my server loaded with 11iv23 os (rx 6600)
is showing continuous memory bottleneck warning in the HP -Openview operations,

What all things that i have to check in the OS level to resolve this problem?

Please mention if any scripts available for the same.here i am not using glance tool.

Is there any log file generated for the same in the server os.

Hi,

First on foremost you want to make sure OpenView is correct in its warnings.

- How much memory is there? And how much do you think should reasonably being used. Processes, Oracle-SGA, ...

- Are there any user complaints?

- Was it happy for a while and then started complaining, or did it always complain? What changed? (more users, additional DB, DB tuning?)

Me, I would doublecheck with vmstat, and swapinfo, what usage it. You may want to add some 'top' number and ipcs -m to see where the memory might be going.

Try and find, and read, a recent version of the "HP-UX Performance Cookbook By Stephen Ciullo and Doug Grumann". http://h21007.www2.hp.com/portal/download/files/unprot/devresource/Docs/TechPapers/UXPerfCookBook.pdf
It pretty much defines the memory bottleneck rule.

Hope this helps some,
