For a two node cluster the following would be a minimum recommended hardware list.
Check the RAC/IBM AIX certification matrix for RAC updates on currently supported hardware/software.
1.1.1 Hardware
· IBM servers - two IBM servers capable of running AIX 4.3.3 or 5L 64bit
· For IBM or third-party storage products, Cluster interconnects, Public networks, Switch options, Memory, swap & CPU requirements consult with the operating system vendor or hardware vendor.
· Memory, swap & CPU requirements
o Each server must have a minimum of 512Mb of memory, at least 1Gb swap space or twice the physical memory whichever is greater.
To determine system memory use:-
$ /usr/sbin/lsattr -E -l sys0 -a realmem
To determine swap space use:-
$ /usr/sbin/lsps -a
o 64-bit processors are required.
1.1.2 Software
· When using IBM AIX 4.3.3:
o HACMP/ES CRM 4.4.x
o Only RAW Logical Volumes (Raw Devices) for Database Files supported
o Oracle Server Enterprise Edition 9i Release 1 (9.0.1) or 9i Release 2 (9.2.0)
· When using IBM AIX 5.1 (5L):
o For Database Files residing on RAW Logical Volumes (Raw Devices):
o HACMP/ES CRM 4.4.x
o For Database files residing on Parallel Filesystem (GPFS):
o HACMP/ES 4.4.x (HACMP/CRM is not required)
o GPFS 1.5
o IBM Patch PTF12 and IBM patch IY34917
or
IBM Patch PTF13
o Oracle Server Enterprise Edition 9i Release 2 (9.2.0)
