Displaying, Copying, and Removing a Snapplan (dbed_vmchecksnap)
Consider these notes before listing all snapplans for a specific Oracle database, displaying a
snapplan file, or copying and removing snapplans.
Table 5-6 Check Snapplan Notes
• If the local snapplan is updated or modified, you must revalidate it.
• If the database schema or disk group is modified, you must revalidate it after running
dbed_update.
Usage Notes
Displaying a Snapplan
You can use the dbed_vmchecksnap command to list all available snapplans, and then use the
dbed_vmchecksnap command to display detailed information for a particular snapplan.
To list all available snapplans for a specific Oracle database
• Use the dbed_vmchecksnap command as follows:
# /opt/VRTS/bin/dbed_vmchecksnap -S ORACLE_SID -o list
In the following example, all available snapplans are listed for the database PROD.
# /opt/VRTS/bin/dbed_vmchecksnap -S PROD -o list
The following snapplan(s) are available for PROD:
SNAP_PLAN SNAP_STATUS
DB_STATUS SNAP_READY
snap1 init_full
init yes
snap2 init_full
init yes
NOTE: The command output displays all available snapplans, their snapshot status
(SNAP_STATUS), database status (DB_STATUS), and whether a snapshot may be taken
(SNAP_READY).
For Database FlashSnap status information, see the Veritas Storage Foundation for Oracle
Administrator’s Guide.
To display detailed information for a snapplan
• Use the dbed_vmchecksnap command as follows:
# /opt/VRTS/bin/dbed_vmchecksnap -S ORACLE_SID -f SNAPPLAN -o list
In the following example, the snapplan snap1 is displayed.
# /opt/VRTS/bin/dbed_vmchecksnap -S PROD -f snap1 -o list
