Creating or Validating the Snapplan Using dbed_vmchecksnap
You can use the VERITAS Storage Foundation for Oracle dbed_vmchecksnap command to
create or validate a snapplan from the command line. You can also use the command to check the
storage to make sure it is configured appropriately for the Database FlashSnap feature.
Note You must have the VERITAS Database FlashSnap license installed in order to use this
command.
Prerequisites
◆ The database must be up and running while executing the dbed_vmchecksnap command.
◆ If the SNAPSHOT_MODE parameter is online in the snapplan, the database must be in
archivelog mode, which is set in the ora.init file, to successfully execute the
dbed_vmchecksnap command.
Usage Notes
◆ The dbed_vmchecksnap command can only be used on the primary host.
◆ The dbed_vmchecksnap command must be run as the Oracle database administrator.
However, the system administrator must prepare persistent FastResync on the existing
database volumes and assign the disks for the snapshot volumes first.
◆ The dbed_vmchecksnap 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.
◆ You have the option to use the dbed_checkconfig command to perform a validation.
◆ The snapplan must be re-validated after making structural changes, such as adding a
tablespace, to your database.
◆ See the dbed_vmchecksnap(1M) manual page for more information.
