THE FOLLOWING STEPS WILL OUTLINE THE RECOVERY PROCESS:
Step 1: RECOVERY OF SPFILE
Create spfile.rcv as:
set dbid= 1499754868
run {
startup nomount force ;
};
opsdba:/u01/ORACLE/opsdba/recovery>rman target / catalog rman10/rman10@rman10p cmdfile=spfile.rcv

connected to target database (not started)
connected to recovery catalog database
RMAN>
executing command: SET DBID
database name is "OPSDBA" and DBID is 1499754868
Oracle instance started

Recovery Manager complete.
opsdba:/u01/ORACLE/opsdba/recovery>
Now restore the spfile
set dbid=1499754868
run {
allocate channel ch1 type 'sbt_tape' parms 'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo.opsdbad.opt)';
restore spfile ;
release channel ch1 ;
}
Step 2: RESTORE OF CONTROLFILES
Same Steps as spfile with the restore command changed. So the new script is
set dbid=1499754868
run {
allocate channel ch1 type 'sbt_tape' parms 'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo.opsdbad.opt)';
restore controlfile ;
release channel ch1 ;
}
Step 3: RESTORE OF DATABASE
Since you have the controlfiles now mount the database
SQL> conn sys as sysdba
Enter password:
Connected.
SQL> alter database mount;
Database altered.
Now get the log sequence number of the database from the catalog database:
select sequence# from rc_backup_redolog where db_name=’OPSDBA’;
RMAN> run {
2> allocate channel ch1 type 'sbt_tape' parms 'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo.opsdbad.opt)';
3> restore database ;
4> recover database until logseq=6; -- GOT FROM THE ABOVE QUERY
5> release channel ch1 ;
6> }
7>
allocated channel: ch1
channel ch1: sid=156 devtype=SBT_TAPE
channel ch1: Data Protection for Oracle: version 5.2.4.0
Starting restore at 12-FEB-07
channel ch1: starting datafile backupset restore
channel ch1: specifying datafile(s) to restore from backup set
Step 4: alter database open resetlogs;
