sar -v output

[PSS SYS ADMIN]

Hi everyone,
I need to know if the subsequent sar -v output it's ok:
17:20:45 text-sz ov proc-sz ov inod-sz ov file-sz ov
17:20:46 N/A N/A 119/276 0 620/620 0 682/1860 0

Elsewhere please suggest me right kernel parameters.

Regards...
PSS

Hi PSS,

Yours are looking good. Don't get alarmed over inod-sz unless your system is configured with HFS filesystems other than /stand.

If you have the application up and running on the box, you are ok. But if the application is still to be brought up, then I would check the 'nproc' parameter. Your current configuration allows only 276 processes to run.

Also, be aware that nfiles set to 1860 is a bit low if you are running any kind of database or file intensive application. Use your sar -v output to monitor how high you actually get and adjust accordingly so that you are well below your nfiles limit. You will get a "File table full" error message if you exceed it.

I think the nproc and nfile is a little bit low on today HP server.

I've attached the tunable kernel parameters.
The system is an L2000 hpux11.00 4cpu x 440mhz
2gb ram with a Cell Manager DataProtector in a SAN environment.
Can you suggest me the correct parameters to set up?
Thanx

hi,

the description of each parameter may be found from SAM.

SAM -> Kernel Configuration -> Configuration Parameters -> look under the Description column
