Moving Control File into ASM

Steps to move your db controlfile into ASM:-

1. Check the parameter on control_files to see current path.

2. Set control_files parameter in db to new path.

    alter system set control_files='/DEV/+VMU01','/DEV/+PSO01' scope=spfile;

3. Now -
     shutdown immediate;
     startup nomount;

4. Using RMAN, restore controlfile from old control_file.
 RMAN> restore controlfile from '+VMU01/vinaydev_streams/controlfile/current.2648.134262629';

5. Now Mount and open the instance.
 alter database mount;
     alter database open;
 

Database Flashback and Backup

Database Flashback and backup:
------------------------------------------------
If you to flashback a database to Guaranteed Restore Point(GRP) that has already been set in the database. Now the backups that were taken after the Guaranteed Restore Point(GRP) was created can no longer be used.  But, you can restore the database to a point in time before to the GRP creation.

Here are the steps:
SQL> shutdown immediate
startup mount
flashback database to restore point VINAYDEV;

Total System Global Area  424647870 bytes
 Fixed Size                  5514791 bytes
 Variable Size             328358173 bytes
 Database Buffers           45679529 bytes
 Redo Buffers                5892829 bytes

Database mounted.
 SQL>
Flashback complete.

SQL> alter database open resetlogs;
Database altered.

Now we can recover and restore the database from backup that was taken prior to the GRP was created-
