5.20.1 Overview of Snapshot-Based Recovery of Database Servers

The recovery of the Oracle VM consists of a series of tasks.

The recovery procedures use the diagnostics.iso image as a virtual CD-ROM to restart the Oracle VM in rescue mode using the Integrated Lights Out Manager (ILOM). At a high-level, the steps look like this:

1. Re-create the following:

   • Boot partitions

   • Physical volumes

   • Volume groups

   • Logical volumes

   • File system

   • Swap partition

2. Activate the swap partition.

3. Ensure the /boot partition is the active boot partition.

4. Restore the data.

5. Reconfigure GRUB.

6. Restart the server.
