Hi,
I have high system memory utilization, about 20 Gb on 32 Gb of physical memory.
I would like verify if the running application process make an high number of system calls
What can I do to verify process system call ?

Thanks for help

If you want to see how many system calls a proccess is making, the tool is tusc. ALos, if you have Glance installed, it can do that same thing.

Tusc's job is to show system calls made and signals recieved by a process. Glance has this as an additional feature. Glance can also show you system wide counts by system call.

GLance is a purchased product, there is a trial on the app CD's. tusc is freely available at the HPUX porting center.

Hope it helps

sar -c can give you system-wide values; if you want to examine this on a per-process basis then Glance would be the tool of choice. If you don't have Glance, you can install a 60-day trial version from any Applications CD set.

You can use glance or download tusc and attach to the PID. It will also be a good idea to make sure you tune your max*siz kernel parameters.
