Restoring a snapshot from clone

Perform the following steps for LVM, ASM, and file system setups before restoring a snapshot from a clone:
  • Ensure that you stop all the Remote copy groups before initiating a snapshot restore operation.

  • Ensure that you dismount the database ASM disk groups from one or more cluster nodes. Also, ensure that you drop the disk groups from one of the cluster nodes servers if ASM is in use when you do not select the Automate Restore option.

  • Ensure to export the database volume groups from the database server if volume groups are in use. For example, for Linux logical volume groups:
    # lvchange -an /dev/rh6lvm-data/lvol0
    # lvchange -an /dev/rh6lvm-data/lvol1
    # vgexport rh6lvm-datavg
  • Ensure that you remove the volumes exported as physical Raw Device Mapping from Oracle server for databases with volumes exported as physical RDM.

  • Ensure that all the prerequisites listed are performed for the cloned database except for dropping the diskgroups for ASM. On the cloned database, all the diskgroups must be only dismounted and not dropped.

  1. Click the main menu and then click Oracle Databases > + Database.
  2. On the master pane of the Databases screen, select a database.
  3. On the Copies tab, select and click the underlined value for Clone.

  4. Select a clone and then click Action > Restore from the Clone window to restore the snapshot for clone.
  5. Specify the Meta Data File Path.
  6. Select or clear Automate Restore Database.
  7. NOTE:

    Perform the steps mentioned in the prerequisites, if Automate Restore Database is cleared.

    The Automate Database Recovery option is unavailable if you clear the Automate Restore Database option.

    • Select the Type as either Recover to this PIT or Recover to another PIT.

    • Select or clear Restore controlfile.

    • [Only for Recover to another PIT option] - Select the date range from the calender. You can also set the Hour, Minute, and Second and click Done.
