About Oracle support for Replication Director

Replication Director can be used to create snapshots of the Oracle database and replicate the snapshots to other NetApp disk arrays. To use Replication Director, the Oracle database must exist on a NetApp NAS disk array. (It is not supported on SAN storage at this time.)

Oracle snapshot backups that use Replication Director are supported on UNIX platforms only.

The administrator can create an Oracle policy to use Replication Director by using either the following methods:

  • The Oracle Intelligent Policy (recommended).

    See Configuring an Oracle Intelligent Policy using Replication Director.

  • Create a script-based Oracle policy.

    See Configuring a script-based Oracle policy.

Table: Differences in Oracle snapshot policy setup describes the differences between the two methods:

Script-based Oracle policy

Scripts

  • All scripts that are necessary to protect all parts of the database are automatically generated at run-time.

  • The administrator does not need to know how to configure RMAN scripts.

  • The retention levels for the different parts of the database are automatically assigned.

  • NetBackup can continue to use custom scripts to perform database backups.

  • The administrator must know how to configure RMAN scripts.

  • The administrator must set the retention levels for the different parts of the database correctly.

  • The administrator must ensure that a snapshot of the proxy data is created.

Schedules

The administrator configures only one schedule that backs up all parts of the database and sets the correct retention automatically.

The Archived Redo Log schedule is not supported with a snapshot backup.

The administrator must configure two schedules with two retentions:

  • One Full Backup schedule to back up the snapshot (proxy) data part of the database.

  • One Application Backup schedule to back up the stream-based part of the Oracle database.

The Archived Redo Log schedule is available with a configured script.

Backups

User-directed backups are not supported. To attempt a user-directed backup (results in a status 240 (no schedules of the correct type exist in this policy).

User-directed backups are supported.

Load balancing

RAC load balancing is not supported.

RAC load balancing is supported.
