ulimit data

GoHP — Thu, 05 Jan 2006 14:15:11 GMT

Please let me know how to set the limit data to match with maxdsiz and maxdsiz_64 kernel parameters.

Can you explain why ulimit data shows 4GB instead of 2GB as maxdsiz ?

HP-UX B.11.11 U 9000/800

ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 4292870144
stack(kbytes) 131072
memory(kbytes) unlimited
coredump(blocks) 4194303
nofiles(descriptors) 1024

kmtune | grep maxd
maxdsiz 2147483648 - 2147483648
maxdsiz_64bit 2147483648 - 2147483648

Hi Minh:

Technical Knowledge Base document #KBRC00012516 notes that 'getrlimit' returns an unsigned long integer that the shell misinterprets as a signed value.

The problem occurs when PHKL_25993 is installed.

But my server had no PHKL_25993 patch installed. Any other patch related ?

Hi (again) Minh:

Your problem seems to fit, however. Posix Shell patch PHCO_28832 (superseded by PHCO_33375) corrects the reporint. See the patch notes for PHCO_33375, for instance.

Check you applied patches with:

# /usr/contrib/bin/show_patches | grep 28832
