Sorry for not being so clear in my requirement. I want two oracle homes for two different versions of oracle. I want to have two different oracle database running on two different oracle home for instance 1 database running on 10.2.0.2 and 10.2.0.4.
My current setup is :-
CRS running on 10.2.0.2
ASM running on 10.2.0.2
DB running on 10.2.0.2
I want a new DB in 10.2.0.4 and hence need to have another home at 10.2.0.4.
In this case, do i need to install a seprate 10.2.0.4 CRS home as well as 10.2.0.4 DB home?
