AIX has its own rules, as I have to discover these days. Coming across ulimit, I found out that smitty configures value A here and value B completely elsewhere. Hardest one so far has been “ulimit -m” (“Specifies the size of physical memory, in number of K bytes.” a user can assign), since I could not find where to specify it in smitty. At some point, I stopped investigating smitty, and went directly to
but it did not become easier, nobody could tell me what’s the parameter for -m in limits’ terms. Some suspicion did go in direction “rss”, but oddly, lsuser delivered “rss=65536″ and ulimit -a delivered “32768”. So at first glance, they did not seem to be connected despite a similar function description in documentation.
But finally, I came over Unix Essentials Blog and was told:
“ulimit -m” is “rss” in limits, so i specified
rss = -1 rss_hard = -1
and was happy. The lsuser command shows “rss=-1″ and ulimit -m shows “unlimited” now. By the way: ulimit -m is specified in KB, rss in blocks …
Thanks to morsing in freenode’s #aix as well!
