Re: system performance

Hi Viney,

There are many tools available. Glance plus is one of the best product if you have.

You can also use top, sar, vmstat, iostat, netstat, swapinfo commands as well to know the resource utilisation.
Best wishes,

Ganesh.

Re: system performance

GlancePlus is the best tool to use. It is optional software but comes with the EOE OS. Without glance you can use top, vmstat, sar.

Re: system performance

GlancePlus would be a good one to use!!

Re: system performance

is it similar to OVO and HP site scope

in vmstat, wht is thing need to be checked

Re: system performance

glance probably gives more details.

Re: system performance

Hi All,

Actually i have ia64 hp server rx3600 server and its cpu utilization is 98 % and memory utilization is 96 % but in system no major process is going on..........

and sar output is:--
17:50:15 %usr %sys %wio %idle
17:50:17 32 65 0 3
17:50:19 32 62 0 5
17:50:21 31 66 0 4
17:50:23 26 71 0 3
17:50:25 29 69 0 2

Average 30 67 0 3

give some suggestion. i don't have glance like software

Re: system performance

Hi Viney,

Use top command to see which procoess consumes more cpu cycles..
Best wishes,

it is show only 4.51,4.49,4.53 % of cpu utilization only......

Re: system performance

viney,

If you have a support contract with HP, you should be able to see this document:

http://www11.itrc.hp.com/service/cki/docDisplay.do?docLocale=en&docId=emr_na-c00958823-12

It gives you all the basics that you need to understand the free basic tools used to troubleshoot performance issues.

Regards,

Jaime.

Re: system performance

> it is show only 4.51,4.49,4.53 % of cpu utilization only

That's for each process. If you add up all the processes you may end up with the 98% utilization. Same for memory.

Having high CPU and memory utilization does not mean there is something wrong. It may be normal for your oracle environment. How much total memory do you have and how many CPUs?
Look further into the top listing, unless you find a single process that unjustifyingly is using a lot of CPU and memory, there is nothing wrong. You may need to add resources to your server.
Another thing to look into is cleanup andy unecesssry processes that may be running on your server. But that's another topic...

Re: system performance

Hi TTr

I have 2 processor and 4 GB RAM

Re: system performance

In general 4GB memory is not enough for an oracle server these days. Same for the 2 CPUs if this is one dual core CPU. You should look in detail in the top output and "ps -ef" listing to see if there are any oracle processes that can be cleaned up or any OS services that can be stopped to conserve CPU and memory resources. Otherwise you need to add CPU and memory.
