Hi,

ipcs -moba will give details of used shared memeory.
If you find any application with 0 NATTACH you can remove this and release shared memonry by
ipcrm -m followed by id #

Good luck

Hello,

if you read the man-pages for the "Memory Windows" there should be a reference to a tool named like "memwin_stat"...
Try this.
It could be available on the HP RC ftp server:
ftp://contrib:9unsupp8@hprc.external.hp.com

HTH,

sorry guys, read the man page on sar and sussed it.
sar -m 10 5 works.
cheers,

mark.

Hi Mark:

You are missing the data collector files because you are not running sadc. However, you can simply invoke sar with a sampling interval and number of samples: e.g. sar -m 2 4 (sample every 2 seconds 4 times).

I doubt however that this metric is useful as it shows transactions/s.
