Single-step restore to ASM storage from an Oracle Copilot recovery point or instant access mount
The following procedure shows how to use RMAN to restore from a recovery point. This procedure is only viable after the command nborair -create_recovery_point is run and the recovery point is mounted on a target client.
Note:
The functionality for single-step restore to ASM storage is not in the GUI. This feature is run with RMAN only.
The procedure example assumes that a recovery point is already mounted and uses the mount point of /db_mp as the example. All RMAN commands must run from the target host.
To perform a single-step restore to ASM storage from a recovery point
- Catalog the backups from the recovery point.
RMAN> catalog start with '/db_mp/'; searching for all files that match the pattern /db_mp/ List of Files Unknown to the Database ===================================== File Name: /db_mp/data_D-ORAC112_I-3955369132_TS-SYSAUX_FNO-2_8hrgu3qd_s-1297_I-3955369132 File Name: /db_mp/data_D-ORAC112_I-3955369132_TS-SYSTEM_FNO-1_8irgu3qk_s-1298_I-3955369132 File Name: /db_mp/data_D-ORAC112_I-3955369132_TS-UNDOTBS1_FNO-3_8jrgu3qr_s-1299_I-3955369132 File Name: /db_mp/data_D-ORAC112_I-3955369132_TS-USERS_FNO-4_8krgu3qt_s-1300_I-3955369132 File Name: /db_mp/arch_D-ORAC112_I-3955369132_SCN-5248163_a8rh0s3b File Name: /db_mp/spfile_D-ORAC112_I-3955369132_T-20160929_a9rh0s3c File Name: /db_mp/cf_D-ORAC112_I-3955369132_T-20160929_aarh0s3d Do you really want to catalog the above files (enter YES or NO)?

- Restore the data files from the point in time of the recovery point.
The following RMAN restore is from disk (DISK). Also, this example uses the NLS_DATE_FORMAT="DD-MM-YYYY-HH24:MI:SS" command that was set in the environment before RMAN was run. Use the date format for your environment.

- Recover the database.
If the restore of archive logs is not available on disk, then the logs are restored from NetBackup (sbt_tape).
