How to Restore Database BCV backup copy to ASM storage:

How big is the database: 2TB
How often we take BCV copy: Daily
How often we delete Archive log's: Every 30 mns.
How much redo, does this DB generate per Hour: 70GB/24= ~3GB
Is this RAC database: Yes.


1.
Stop all instances of database:
srvctl stop database -d ORADB

2.
Check the services are offline:
crs_stat -t

3.
Dismount diskgroups on all instances:

alter diskgroup ORADB_T1_BACKUP_01 dismount;
alter diskgroup ORADB_T1_DATA_01 dismount;
alter diskgroup ORADB_T1_DATA_02 dismount;
alter diskgroup ORADB_T1_DATA_03 dismount;
alter diskgroup ORADB_T1_DATA_04 dismount;
alter diskgroup ORADB_T1_DATA_05 dismount;
alter diskgroup ORADB_T1_REDO_01 dismount;

4.
Have SysAdmin restore the database from BCV:

Is there any difference in restoring BCV copy to file system Vs ASM?
There is technically no difference in restoring BCV copy to file system Vs ASM.

Can ASM disk names be different?
No, should be same between source and target.

5.
Mount back diskgroups on all instances:

alter diskgroup ORADB_T1_BACKUP_01 mount;
alter diskgroup ORADB_T1_DATA_01 mount;
alter diskgroup ORADB_T1_DATA_02 mount;
alter diskgroup ORADB_T1_DATA_03 mount;
alter diskgroup ORADB_T1_DATA_04 mount;
alter diskgroup ORADB_T1_DATA_05 mount;
alter diskgroup ORADB_T1_REDO_01 mount;
