Prerequisites
PFILE updated with auxiliary values: In addition to the updates to the PFILE as specified in the Non-RAC duplication procedures, the following additional updates must be made when the source database is a multi-instance database:
|
1 |
|
• |
<database/instance_name>.cluster_database=TRUE |
|
• |
<instance_name>.instance_number=N |
|
• |
<instance_name>.thread = N |
|
• |
<auxiliary_instance_name>.thread = 1
Post-restore procedure
After completion of the Restore Duplicate Database Procedure as defined in the Duplicating a database in a non-RAC environment, you can convert the resulting single-instance database to a multi-instance database. To do so, use one of the procedures detailed in Converting to Oracle Real application Clusters from Single-Instance Oracle Databases in the Oracle Real Application Clusters Installation Guide.
Using the Plug-in in a failover cluster environment
Oracle Server Fail Safe Failover Clustering: an overview
Oracle Fail Safe Failover Clustering (Active/Passive) is designed to provide high-availability for an entire Oracle Server instance. For example, you can configure an Oracle Server instance on one node of a failover cluster to fail over to any other node in the cluster during a hardware failure, OS failure, or a planned upgrade.
A failover cluster is a combination of one or more nodes (hosts) with one or more shared disks. Various resources hosted by the nodes, such as IP, shared storage, and an application — Oracle in this case — can be grouped to create a Clustered Service. A Virtual Service appears on the network as if it were a single computer running an application, but provides failover from one node to a different node if the current node becomes unavailable.
|
IMPORTANT: In NetVault Backup terminology, a clustered service is accessed by a Virtual Client. The references to Virtual Client in Plug‑in for Oracle are basically references to the Clustered Service in the Oracle Server Failover Cluster environment. |
Plug‑in for Oracle provides support for Oracle Server Failover Clustering. Using the failover cluster network name, the plug-in is able to identify the current node that is in control of the Oracle Server Clustered Service and target it for backup.

The following topics only offer information on Oracle-specific settings required for the use of this plug-in in a Failover Cluster environment. They do not offer instructions on how to set up NetVault Backup’s Application Cluster Support to administer backups and restores of non-Oracle Server-related data and files. This process is not plug-in-specific, and you can find complete details in the Quest NetVault Backup Administrator’s Guide. |

Before you continue, review all cluster-related information provided in the Quest NetVault Backup Administrator’s Guide to understand how the following information works with Oracle Server Failover Cluster functionality. |
