[Rkumar]

thanks a lot,

how to find that my system requires more memory. I mean installed RAM is not sufficient.
i mposting some outputs as much as i know.

I think system does not need more ram . The RAM in current is enough.

Please suggest me how to find memory bottleneck?. Is there any bottleneck in this system?

Rahul

[Johnson Punniyalingam]

You can start with "Glance" is easy to use ?

# glance


# echo total_lockable_mem/D | adb /stand/vmunix /dev/mem
-- How much lockable memory is being used?

# ipcs -mob
-- What is the shared memory load?


To see what is using all your virtual memory:

$ UNIX95= ps -efo vsz,ruser,pid,ppid,args | sort -rn | more

[Steven E. Protter]

Shalom,

swapinfo -tam

vmstat

If no paging is happening your system needs no more ram. It is possible even if it is to reduce demand for memory with kernel settings and reducing Oracle SGA.

But we are talking about a 10.20 system. A modern system with a supported OS might simply be able to manage better.

Post the output of the commands for further advice.

Dear experts,

Please let me know how to use cstm to gather info related to memory.

Why do you think there is a memory bottleneck?
CPU 0 has 78.2% SYS.

>let me know how to use cstm to gather info related to memory.

You have more than 392 Mb. What more do you need to know?

Dear Experts Please suggest on this

[Pete Randall]

Run vmstat for a longer interval, like every second for 30 seconds:

vmstat 1 30

(or longer) and keep an eye on the "po" column. Ideally, it should remain zero, or at least in the low single digits. Once you get into double digits (above 10) then you've got memory problems.
