To create a snapplan
1. Change directories to the working directory you want to store your snapplan in.
$ cd /working_directory
2. Create a snapplan with default values using the dbed_vmchecksnap command:
$ /opt/VRTS/bin/dbed_vmchecksnap -S ORACLE_SID \
-H ORACLE_HOME -f SNAPPLAN -o setdefaults -t host_name \
[-p PLEX_TAG]
3. Open the snapplan file in a text editor and modify it as needed.
For information on creating a snapplan using the GUI, see “Using the VERITAS Storage
Foundation for Oracle Graphical User Interface” on page 265.
Example
In this example, a snapplan, snap1, is created for a snapshot image in a single-host configuration
and default values are set. The host is named host1 and the working directory is
/export/snap_dir.
$ cd /export/snap_dir
$ /opt/VRTS/bin/dbed_vmchecksnap -S PROD \
-H /oracle/product/9i -f snap1 -o setdefaults -t host1
Snapplan snap1 for PROD.
