on HPUX 11.11 systems on PA-Risc
I'd like to know if there is any way to see if there is a fragmention in the shared memory , in the free area or in the used by any processes , for the shared memory areas that related to 32bit application (1.7gb) and on 64bit application.
I know know how to use 'ipcs' and 'ipcrm' in order to see the segments that are in use, but i don't know how to see the largest contingous free (and used) area in the shared memory.
if anyone has any idea, please let me know.
Thanks people.

Re: question about shared memory
i already checked this proggram - I'm not sure i understood it correctly.
on the last section:
Maximum shmem segment: 1048576 Kbytes (shmmax)
Largest free segment: 1048576 Kbytes (Window id 0 (global) quadrant 2)
Available swap : 3274192 Kbytes (swapspc_cnt)
Available pseudo-swap: 864028 Kbytes (swapmem_cnt)
according to that, my largest free segment is about 1gb, for 32bit application.
but it can't be true, I receive the exact same result, even on machines i'm sure the whole free space should be much smaller (i have a machine that runs Oracle8i 32bit, that uses 1.4 gb out of 1.8 available shared memory for 32bit proggrams, and yet, i receive this result.
