How to display/monitor application use of memory segments

[J.Martin]

Trying to confirm kernel parm settings are adequate for large application. I've displayed the settings for maxdsiz, maxssiz, maxtsiz and the 64bit parms using kctune.

How do I display what amount of each segment a process is using?

You'll need to install Glance Plus to see all these regions. You can get a bit of information from chatr and other development tools. However, the kernel limits you mentioned are per-process. Each process gets 4 quadrants of memory space to map as needed. The limits keep bad programs from using all of RAM. Of course, a correctly written program may need a lot of data space so you have to allow for this.

I have glance plus installed but don't see how to display the a particular process memory segment usage. I've tried both glance and gpm.

Is it possible to display a particular processes memory segment usage?

Thanks,

Hadn't seen the "M" option in Glance previously. Giving it a PID looks to display the information I am looking for.

Thanks for pointing me in the right direction.

There is also a great utility called kmeminfo ( non-supported HP tool ).

Do a search for it on this forum..

Per process mem usage etc...

In this case kmeminfo is the equivalent of hitting a fly with a sledgehammer -- effective, but a little much.

Glance is good too... but pstat's got enough information to handle this.

See attached program written with a different purpose in mind (summarizing Virtual/Physical/Lockable/Swap usage for a particular process or the system by memory object type). In this case, it could easily be modified to just print the virtual sizes for the 3 types you care about [PS_TEXT, PS_DATA, PS_STACK] for each PID on the system.
