Full Discussion: reduce available ram
Operating Systems AIX reduce available ram Post 302103714 by bakunin on Saturday 20th of January 2007 09:00:09 PM

One needs two things to do it dynamically: AIX 5.3 and a LPAR.

Taking away or adding memory (without getting physical, that is ;-) ) is only possible in a LPAR machine, to do it without having to reboot is only possible with 5.3 onwards. Machines with older versions of the OS will have to be rebooted.

What you *can* do, though, is to create a RAMdisk with the "mkramdisk" command. This way you can take away arbitrary amounts of memory which the system doesn't have (effectively) available any more.
