To mount a Storage Checkpoint carried over from the snapshot volumes to a secondary host
1. On the secondary host, list the Storage Checkpoints carried over from the primary database
using:
# /opt/VRTS/bin/dbed_ckptdisplay -S ORACLE_SID -n
2. You can mount one of the listed Storage Checkpoints using:
# /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_vmclonedb -o umount,new_sid=new_sid -f
SNAPPLAN
• It is only possible to mount a Storage Checkpoint carried over with the snapshot volumes
in a two-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.
NOTE: If you use the Oracle online backup method, you must also back up all the archived
log files in order to do a complete restore and recovery of the database.
Cloning a Database (dbed_vmclonedb)
Veritas Storage Foundation lets you 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 clone rather than from the primary database to avoid introducing
additional burdens on the production database.
A clone database can also serve as a valid backup of the primary database.
You can also back up the primary database to tape using snapshot volumes.
The resynchronization functionality of Database FlashSnap allows you to quickly refresh the
clone database with up-to-date information from the primary database. Reducing the time taken
to update decision-support data also lets you generate analysis reports more frequently.

Using Database FlashSnap to Clone a Database
In a single-host configuration, the dbed_vmclonedb command creates a clone database on the
same host. The command can also be used to shut down the clone database and unmount its file
