For each machine running IBM AIX, configure AIX to allow large file sizes and set the memory requirements to their hard limits. To make these changes, modify the following lines in the /etc/security/limits file as follows:
fsize = -1
(indicates
unlimited file size)
rss = -1
(indicates
unlimited memory)
data = -1
(indicates
unlimited data segment)
The changes take effect upon your next log in. Users logged in at the time of the change must log out and back in again for the change to take effect.
