DATA RECOVERY ADVISOR feature in Oracle 11g Release 2

Hi Guys,

Today I would like to post  about new feature in RMAN (Oracle 11g Release 2).     Earlier if we lost any datafile or control file we have to manually find it and restore it.   Sometimes it looks very bad time when we are trying to restore database in point-in-time-recovery.   Its due to we may put wrong time or SCN to restore the database .

Now Data Recovery Advisor is reducing our manual work as well as it will restore it database back to its last successfully working conditon.

Please see below how it works


Case 1: If you lost the non- mandatory one or more datafiles( means other than SYSTEM,SYSAUX, UNDO ).

step1 :
[oracle@prodserver ~]$ sqlplus
