PowerProtect Data Manager 19.12 Oracle RMAN User Guide

PDF

Supporting existing Oracle RMAN agent backups with PowerProtect Data Manager

The Oracle RMAN agent 19.1 introduced the capability to onboard existing stand-alone deployments, including their existing backups, to PowerProtect Data Manager. Existing backups are Oracle RMAN agent backups that you performed before you have integrated the Oracle RMAN agent with the PowerProtect Data Manager software and added an asset to a PowerProtect Data Manager protection policy.

NOTE

To enable the PowerProtect Data Manager discovery of existing stand-alone backups, you must set the ENABLE_BROWNFIELD_DISCOVERY parameter to TRUE in the configuration file, as described in Configuration file requirements for connection to local databases.

Retention lock is not supported for discovered existing backups in PowerProtect Data Manager.

Onboarding of DD Boost-over-FC backups is not supported.

With the onboarding capability, PowerProtect Data Manager provides the following centralized features:

  • Visibility of both existing backups and any new self-service or PowerProtect Data Manager policy-driven backups of onboarded assets.
  • Retention management of all discovered backups. The retention time of existing backups can be set during the PowerProtect Data Manager registration.
  • Automatic configuration of target protection storage based on the PowerProtect Data Manager protection policies that are used for your database.
  • All the other functionality that is provided for PowerProtect Data Manager protection policies.

Self-service operations use the DD backup host and storage unit managed by PowerProtect Data Manager

With Oracle RMAN agent 19.1 or later, you can provide the DD backup host and storage unit in the RMAN scripts. After you use PowerProtect Data Manager to add an asset to the protection policy, you might want to keep using the existing RMAN scripts instead of or along with scheduling backups through PowerProtect Data Manager.

When you create a protection policy, the PowerProtect Data Manager software can either create or reuse a storage unit on the specified DD system backup host, subject to limitations. All subsequent backups of assets in that protection policy go to this storage unit. This implementation overrides the backup host and storage unit information from the script with the backup host and storage unit information from PowerProtect Data Manager.

NOTE

If any asset on the host is being managed by PowerProtect Data Manager, only the delete operations performed through PowerProtect Data Manager are supported. Self-service delete operations through rman delete or ddutil delete are not supported.

If you plan to manage all assets on a host by using the stand-alone RMAN agent and not the PowerProtect Data Manager, ensure that the hidden files .app.settings and .ddbmcon.gatherinfo are removed from the $RMAN_AGENT_HOME/settings directory.

On a host where at least one asset is being managed by PowerProtect Data Manager, do not remove the hidden files .app.settings and .ddbmcon.gatherinfo. In this case, the file removal will result in unexpected behavior.

Setting and reporting the retention time for existing backups

With Oracle RMAN agent, any backups that are performed before you add an asset to a PowerProtect Data Manager protection policy are considered existing backups. You can set the retention time for existing backups during registration with the PowerProtect Data Manager server by using the configureAddOn.sh script. This retention time is reported to PowerProtect Data Manager during backup discovery.
