If the only thing running on this cluster is Oracle RAC, then you don't really need HACMP (or GPFS) assuming you are going to use ASM for your storage method. ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of David Barbour Sent: Monday, October 29, 2007 11:12 AM To: ofabelo@xxxxxxxxx Cc: oracle-l@xxxxxxxxxxxxx Subject: Re: Oracle 10G + SAN + HACMP The HACMP piece should probably be left to an experienced AIX admin. Oracle doesn't really come into play when setting up an HACMP failover. Just curious as to why you'd choose HACMP over RAC?

I don't know nothing about san and hacmp+oracle nowadays. Someone knows of documentation about all this? Thanks beforehand. Cheers...
