You can use SMIT as described below or simply use lsattr/chdev.
The former will list the current setting as in:
# lsattr -E -l sys0 -a maxuproc
maxuproc 40 Maximum # of processes allowed per user True
and you can then increase the maxuproc parameter:
# chdev -l sys0 -a maxuproc=200
sys0 changed
If you just type ‘lsattr -E -l sys0’ you will get a list of all
parameters, some of which can be changed but not others.
If you want to use smit, do as follows:
smit
