Figure 5-6 shows a typical configuration when snapshot volumes are used on a secondary host.
Figure 5-6 Example System Configuration for Database Backup on a Secondary Host
Table 5-8 Backup Snapshot Notes
• You must be logged in as the Oracle database administrator to use dbed_vmclonedb
command.
• Before you can use the dbed_vmclonedb command, you must validate a snapplan and create
a snapshot.
• The volume snapshot must contain the entire database.
• Before you can use the dbed_vmclonedb command with the -r relocate_path option
(which specifies the initial mount point for the snapshot image), the system administrator
must create the mount point and then change the owner to the Oracle database administrator.
Prerequisites
• The dbed_vmclonedb command can be used on the secondary host.
• In a single-host configuration, the primary and secondary hosts are the same.
• In a single-host configuration, -r relocate_path is required.
• In a two-host configuration, the vxdbavol=vol_name option is required.
• If SNAPSHOT_MODE is set to offline or instant, a two-host configuration is required and -r
relocate_path is not allowed.
• See the dbed_vmclonedb(1M) manual page for more information.
Usage Notes
NOTE: You cannot access Database FlashSnap commands (dbed_vmchecksnap, dbed_vmsnap,
and dbed_vmclonedb) with the VxDBA menu utility.
Mounting the Snapshot Volumes and Backing Up
Before using the snapshot volumes to do a backup, you must first mount them.
To mount the snapshot volumes
• Use the dbed_vmclonedb command as follows:
# /opt/VRTS/bin/dbed_vmclonedb -S ORACLE_SID -g snap_dg -o
mount,new_sid=new_sid -f SNAPPLAN [-H ORACLE_HOME] [-r relocate_path]
You can now back up an individual file or a group of files under a directory onto the backup
media.
In this example, snapshot volumes are mounted.
# /opt/VRTS/bin/dbed_vmclonedb -S PROD -g SNAP_PRODdg -o
mount,new_SID=NEWPROD -f snap1 -r /clone/single
dbed_vmclonedb started at 2006-03-02 15:35:41
Mounting /clone/single/prod_db on /dev/vx/dsk/SNAP_PRODdg/SNAP_prod_db.
