2 Node RAC -Adminstrator Manged ORpolicy-managedDatabase - which is better

Question

We are planning to build a 2-node RAC 11gR2 . I went through the documentation and found that administrator managed datbase is better when the no of nodes are very less .
Need your inputs on this as we are still in the designing stage of the setup.

Answer 1

Shashi,
It all goes back to your objective. As you mentioned, it is two node RAC and I assume that you are gonna use this cluster database for one application. If that is the case then go with Administrator managed database because then you will have more control and require less configuration. Policy managed is more useful when you are implementing a true grid solution where database is used as a service and multiple applications are accessing data via the database services provided inside the large real application cluster system. When I say database as a service, people may want to consolidate smaller databases into the bigger RAC system to reduce operating cost and overhead while providing same level of database access to the applications.
So to answer your question, go with Administrator managed RAC. I hope I have provided you enough information for your decision :-)
