Veritas Storage Foundation™ for Oracle 5.0.1 Administrator's Guide

Note: Make sure the volumes used by the database are configured properly before
attempting to take a snapshot. This requires superuser (root) privileges.
Anytime you change the structure of the database (for example, by adding or
deleting datafiles, converting PFILE to SPFILE, or converting SPFILE to PFILE),
you must run dbed_update.
Database FlashSnap commands must be run by the Oracle database administrator
instance owner.
To create a snapshot image of a database
1
Create a snapshot mirror of a volume or volume set.
See Creating a snapshot mirror of a volume or volume set used by the
database on page 232.
2
Use the dbed_vmchecksnap command to create a snapplan template and check
the volume configuration to ensure that it is valid for creating volume
snapshots of the database.
The snapplan contains detailed database and volume configuration
information that is needed for snapshot creation and resynchronization. You
can modify the snapplan template with a text editor.
The dbed_vmchecksnap command can also be used to:
List all snapplans associated with a specific ORACLE_SID
(dbed_vmchecksnap -S ORACLE_SID -o list).
Remove the snapplan from the repository (dbed_vmchecksnap -S
ORACLE_SID -o remove -f SNAPPLAN).
Copy a snapplan from the repository to your local directory
(dbed_vmchecksnap -S ORACLE_SID -o copy -f SNAPPLAN).
3
Use the dbed_vmsnap command to create snapshot volumes for the database.
