Is there a command to get various type of memory utilization

[Prem Mehrotra]

HP has various kinds of memory utilizations: text, data, stack, shared memory. I know how to get shared memory utilization by different processes using ipcs, but looking for command to find: text, data, stack utlization.

In another thread "running 32 bit java on 64 bit HP UNIX", I have pointed out I keep getting memory errors even when my server has 10GB+ free memory as shown using gpm, glance. My maxdsiz is set to 4GB, maxssiz 124M and maxtsiz 100M. Looking at ulimit -a everything else is unlimited.

That would be glance.
Typically you don't care about text and stack. Unless you have thread stack overflows.

You need to measure this when you have the error, not when the system is quiet.

Hi,

Glance

or

You can download procsize utility to get the memory usage of each process based on TEXT,DATA,STACK,SHARED MEMORY & MEMORY MAPPED FILES.

Example
----------

# ./procsize -fnc | more
pid Comm UAREA TEXT DATA STACK SHMEM IO MMAP Total
2916 getty v 4 5 6 4 0 0 349 369
2287 prm3d v 68 6 671 513 0 0 37212 38471

Download Information:-
--------------------
procsize is available for download here:

System: hprc.external.hp.com (192.170.19.51)
Login: eh
Password: spear9
ftp://eh:spear9@hprc.external.hp.com/procsize.README.txt
ftp://eh:spear9@hprc.external.hp.com/procsize.sh

addendum....

NOTE: numbers in the output of procsize are the number of 4K pages. So, mulitply by 4096 to get a byte count.

Whence I enter glance, it only shows me Memory RSS/VSS (probably real/virtual). I do n't see separation in terms of text, stack and data.

For some reaosn ftp fails,, i.e., when I entre login and password, I get a message login incorrect,

Hi,

you can use vmstat command or there is tool kmeminfo through which you can capture the mem usage.

thanks

You need to look at the memory region details for a specific process. You will have to add up a bunch of numbers.
