data segment on AIX

Hi guys,

Are all users authorised to modify the data segment and stack segment to unlimited on AIX?
Is a reboot required after giving ulimit -d unlimited?

There are hard limits and soft limits. Hard limits are changed by root only and represent upper limits. They are stored in the stanza file "/etc/security/limits".

A non-root user can change the "soft limits" of his own account using the "ulimit" command, but only within the "hard limits" set by root. There is no reboot needed to change it, not even a new session (you do not have to log off/log on again).

I hope this helps.
