Copying a Snapplan
If you want to create a snapplan similar to an existing snapplan, you can simply create a copy
of the existing snapplan and modify it. To copy a snapplan from the VxDBA repository to your
current directory, the snapplan must not already be present in the current directory.
To copy a snapplan from the VxDBA repository to your current directory
• Use the dbed_vmchecksnap command as follows:
# /opt/VRTS/bin/dbed_vmchecksnap -S ORACLE_SID -f SNAPPLAN -o copy
In the following example, the snapplan, snap1, is copied from the VxDBA repository to the
current directory.
# /opt/VRTS/bin/dbed_vmchecksnap -S PROD -f snap1 -o copy
Copying 'snap1' to '/export/snap_dir'
Removing a Snapplan
A snapplan can be removed from a local directory or repository if the snapplan is no longer
needed.
To remove a snapplan from the VxDBA repository
• Use the dbed_vmchecksnap command as follows:
# /opt/VRTS/bin/dbed_vmchecksnap -S ORACLE_SID -f SNAPPLAN -o remove
In the following example, the snapplan, snap1, is removed from the VxDBA repository.
# /opt/VRTS/bin/dbed_vmchecksnap -S PROD -f snap1 -o remove
The snapplan snap1 has been removed.
Creating a Snapshot (dbed_vmsnap)
The dbed_vmsnap command creates a snapshot of an Oracle database by splitting the mirror
volumes used by the database into a snapshot database. You can use the snapshot image on
either the same host as the database or on a secondary host provided storage is shared by the
two hosts.
The snapshot image created by dbed_vmsnap is a frozen image of an Oracle database’s datafiles.
The dbed_vmsnap command ensures that a backup control file is created when the snapshot
database is created, which allows for complete data recovery, if needed.
For Database FlashSnap status information, see the Veritas Storage Foundation for Oracle
Administrator’s Guide.
