Re: Question about RAC

Sorry I should have stated clearer.

Say we have server srv1 and srv2 a database called RAC in the shared storage
and a instance rac1 in srv1 and rac2 in srv2, that is the usual
implementation I have seen.

The customer wants this:

database RAC and CAR in shared storage

instance rac1 and car1 in srv1
instance rac2 and car2 in srv2

Obviously rac1 and rac2 forms RAC and car1 and car2 forms CAR. Not very
logical in my opinion, seems like others think so.

TIA

Do you mean for a single database,  use 4 instances each in 2 servers??

Then what is the meaning of high availability??

If the customer wants RACing 4 seperate databases each with 2 RAC
instances on the 2 servers/nodes, then that is possible.

If it is the first case, you have to educate the customer...
