Creating or Resynchronizing a Snapshot Using dbed_vmsnap
You can use the VERITAS Storage Foundation for Oracle dbed_vmsnap command to create a
snapshot image of an Oracle database, tablespaces, or tables. The snapshot can be used locally or
on another host that is physically attached to the shared storage. You can also resynchronize the
snapshot image back to the original database.
Prerequisites
◆ Before the Oracle database administrator can use this command, the system administrator must
prepare persistent FastResync on the existing database volumes and assign disks for snapshot
volumes.
Usage Notes
◆ The dbed_vmsnap command can only be used on the primary host.
◆ The dbed_vmsnap command must be run as the database administrator.
◆ The dbed_vmsnap command does not interact with the user.
◆ It is recommended that you maintain different snapplans in a directory. If a snapplan is updated
or modified, you must re-validate it using the dbed_vmchecksnap command.
◆ See the dbed_vmsnap(1M) manual page for more information.
