AIX

Hi

Mine is a two node ha cluster. i have a user named sybase for whom i was asked to change the stack and memory value to unlimited in one of the node. i know that it can be done via smitty chuser. but will it impact as i will be doing the changes in only one of the node. the user sybase is part of the ha cluster and it is present in both the nodes.

Code:

smitty cl_chuser

will change the values on all nodes for the chosen resource group

if you want to apply this changes just to one of the nodes, change the values in /etc/security/limits on this node


but don't forget to restart your application afterwards, and make sure the new values are loaded (su - to the user, or log out/in), check with

Code:

ulimit -a

To expand on what funksen already explained: there are several commands in an "HACMP-ized" form, which do the sameas their normal counterparts on all the nodes simultanuously so that consistency is preserved. The usually are named like the standard commands but with a "cl_" in front.

Smitty carries this concept over in its fastpaths.

I hope this helps.
