Oracle 11gR1 RAC installtion with ASM What is better 2 or 3 Homes ?

Hi,

We are planning to install New oracle RAC on AIX as I know the installation three homes one for DB home ,ASM Home, CRS home as same in documentation for 11gR1.

on of my colleges suggest to install Two home only (CRS,ASM+DB same home ) and this doable and easier to manager . Any feedback ?

Hi,

I recommend you to have separate Oracle Homes for each product, that way you can patch and upgrade without affecting the other components. Having less oracle homes looks like easier to mantain, but it's harder in the long run.
