Lots of stuff to think about!

You need to think about the reasons for running RAC. Is it to overcome downtime due to scheduled server outages? Or for high availability (ie 24x7 or as close as possible)? Are you trying for a 2-site cluster (much harder to administer and set up)?

Anyway you need a way to get to the data which is shared between the cluster nodes, raw disk or a clustered filesystem or NFS- you can use ASM (raw disk shared across cluster ie all backups via Oracle) or GPFS (filesystem shared across cluster, backups via Oracle interacting with backup s/w such as TSM). Both supported with AIX. Also you can look at HACMP shared raw LVs (not v popular these days) or a NAS (though then access to DB is via NFS).

You will need to consider what happens in the different failure scenarios. Especially for 2-site scenario, as you will likely find you will need 3 sites (3rd site is a voting site).

There are documents available with examples for setting up RAC and GPFS from the IBM Oracle Competency Centre. Contact oraclibm fr ibm com for the "Oracle 10g RAC cookbook on IBM pseries running AIX".

Then you can start thinking about tuning as well!

Don't forget about having enough capacity available in case one server is unavailable for a long time.

For availability you will need to consider lots of other stuff to reduce outages (e.g. AIX multibos)

Luck!

cmhaltcl

cmhaltcl(1m)															      cmhaltcl(1m)

NAME

       cmhaltcl - halt a high availability cluster

SYNOPSIS

       cmhaltcl [-f] [-v]

DESCRIPTION

       cmhaltcl  causes  all  nodes  in a configured cluster to stop their cluster daemons, optionally halting all packages or applications in the
       process.

       To stop a cluster, a user must either be superuser(UID=0), or have an access policy of FULL_ADMIN  allowed  in  the  cluster  configuration
       file. See access policy in cmquerycl(1).

       This  command  will  halt  all  the  daemons on all currently running systems.  If the user only wants to shutdown a subset of daemons, the
       cmhaltnode command should be used instead.

   Options
       cmhaltcl supports the following options:

	      -f   Force the cluster to shutdown even if packages or group members are currently running.  This will cause the packages and  group
		   members to be halted.  If a package halt fails, the cluster halt will also fail.

	      -v   Verbose output will be displayed.

RETURN VALUE

       cmhaltcl returns the following value:

	       0   Successful completion.
	       1   Command failed.

EXAMPLES

       Halt the cluster daemons:

	      cmhaltcl
