Today while checking and validating our database backups for our Oracle 11gR2 RAC and R12 EBS Oracle environments, I wanted to test out the Data Recovery Advisor with 11gR2 RAC. Well, turns out, it is not supported! When you try to issue the DRA commands from RMAN, you get the following message:
[oracle@rac1 ~]$ rman target RAC1

After checking this on My Oracle Support (http://support.oracle.com), I discovered that indeed, Oracle does not support their new feature for backup and recovery (Data Recovery Advisor) on RAC!
Now this is confusing because in the Oracle 11gR2 documentation, it specifies that DRA is supported by RAC when in fact, it is not supported and does not work!
Reference:
Documentation wrong with RAC and DRA - Data Recovery Advisor. (Oracle Database Administrator's Guide 11.2) [ID 1297071.1]
So folks, you cannot use the cool new 11g feature data recovery advisor with RAC! I was bummed to find this out as it is a cool feature and worked in 11gR1.
