Enable multi-stream backups for Oracle protection policy

To enable multi-stream Oracle backups for a centralized protection policy, you can set the parallelism value as the number of Oracle backup channels in the PowerProtect Data Manager UI. As an alternative, you can set the PARALLELISM parameter in the configuration file rman_agent.cfg.

Determine the required number of Oracle backup channels based on the system capacity. With the parallelism setting, you can override the number of backup channels from the Oracle RMAN agent client side.

In the PowerProtect Data Manager UI, perform the following steps to set the parallelism for multi-stream backups:

1. Select Infrastructure > Assets > Oracle.
2. Select the Oracle asset.
3. Select More Actions > Set Stream Count.
4. Set the stream count for each backup level as a value between 1 and 255 in the Full, Incremental Cumulative, Incremental Differential, and Log fields.
5. Click Save.

As an alternative, you can set the PARALLELISM parameter in the $RMAN_AGENT_HOME/config/rman_agent.cfg file on the Oracle RMAN agent host. For example, when you set the PARALLELISM parameter to 6, the Oracle backups run with 6 channels:

PARALLELISM = 6
