Back Up with the Number of Channels (Streams) Option

In the following example, you are backing up data to a changer with two tape drives. If you have several single tape drives of the same type and you want to use them all for a multistreaming backup job, ensure that you assign tapes to different device groups.

To back up data using multistreaming

1. On the Backup Manager Source tab, select two tablespaces.
2. On the Oracle Options tab, specify a number higher than one in the Number of Channels (Streams) option. Keep in mind that RMAN will determine the actual number of channels needed for the backup job. The value you enter on the Oracle Options tab is the maximum number of channels used by RMAN.
3. (Optional) Specify a name for the Media Pool. You can use either an existing Media Pool name or a new Media Pool you create for the multistreaming job.

   Note: Do not select a specific media or media device group. Doing so prevents multistreaming from occurring.

4. Click Submit to submit the job.

   You can monitor the job on the Job Status Manager.
