Hello All. When you do a ulimit -a (AIX 5.2), does memory line (32768 KB) mean that is how much memory one process can use up? Also, how can you change that limit? I tried doing a ulimit -m 65536 but when I log out/in the number goes back to the original number. Thanks for your help.
 

update /etc/security/limits or add the ulimit -m command to your profile.
 
Would just add the following line to my limits file under the user I want it to be for (lets say root):

memory = 65536


 
I think the 'IBM recommended' way would be to change the rss attribute with chuser -

xxxx1234(root)# lsuser -a rss user1
user1 rss=65536
xxxx1234(root)# su - user1
xxxx1234(user1)# ulimit -m
32768

xxxx1234(root)# chuser rss=131072 user1
xxxx1234(root)# su - user1
xxxx1234(user1)# ulimit -m
65536

rss is in 512 byte blocks
ulimit -m is in kbytes
 

The IBM-recommended way is no more than a frontend to edit /etc/security/limits file...
