Veritas Storage Foundation 5.1 SP1: Storage and Availability Management for Oracle (5900-1504, April 2011)

You can mount one of the listed Storage Checkpoints using the

dbed_ckptmount command.

For example:

$ /opt/VRTS/bin/dbed_ckptmount -S ORACLE_SID -c CKPT_NAME \

-m MOUNT_POINT

Note the following limitations:

■ Any mounted Storage Checkpoints must be unmounted before running

the following commands:

$ /opt/VRTS/bin/dbed_ckptumount -S ORACLE_SID -c CKPT_NAME

■ It is only possible to mount a Storage Checkpoint carried over with the

snapshot volumes in an off-host configuration if the snapshot volumes

were mounted with the dbed_vmclonedb command with the -o mount

option without the use of -r relocate_path.

■ Storage Checkpoints carried over with the snapshot volumes can be

mounted before a clone database is created using dbed_vmclonedb with

the -o mount option. After a clone database is created using

dbed_vmclonedb with the -o recoverdb option, however, Storage

Checkpoints are no longer present.

To back up the database using the snapshot

◆

Copy the snapshot volumes to tape or other appropriate backup media.

Restoring from backup

For single instance Oracle environments, backup copies are used to restore volumes

lost due to disk failure, or data destroyed due to human error. If a volume’s data

is corrupted and you know that you need to restore it from backup, you can use

Database FlashSnap’s reverse resynchronization function to restore the database.

Cloning a database (dbed_vmclonedb)

The SFDB commands enable you to create a clone database using snapshot

volumes. You can use snapshots of a primary database to create a clone of the

database at a given point in time. You can then implement decision-support

analysis and report generation operations that take their data from the database
