Building a Continental Cluster
Support for Oracle 9i RAC Instances in a ContinentialClusters Environment
Chapter 5 277
Configuring the Environment for ContinentalClusters
to Support Oracle 9i RAC
In order to enable ContinentalClusters support for Oracle 9i RAC, there
needs to be a set of configurations, which include HP StorageWorks
Continuous Access XP, Oracle 9i RAC, and ContinentalClusters. To use
this feature, it is assumed that you have already configured Oracle 9i
RAC using XP disk arrays and SLVM volume groups for storing the
databases and use XP/CA for replicating data between two clusters.
Also, it is assumed that you have already installed and configured
ContinentalClusters in your environment. Refer to the HP
StorageWorks and Oracle 9i RAC manuals for the complete installation
and configuration information of these products.
Use the following set of procedures to enable ContinentalClusters
recovery support for Oracle 9i RAC instances:
1. Configure XP/CA for data replication. SLVM volume groups
need to be configured on XP disk arrays for storing Oracle database.
In addition, data replication using XP/CA needs to be setup between
the XP disk arrays associated with primary and recovery clusters.
For more details, refer to Chapter 6, “Physical Data Replication for
ContinentalClusters Using Continuous Access XP”.
2. Configure Oracle 9i RAC. All the database files need to be
configured to reside on the volume groups configured in the previous
step. The same Oracle 9i RAC configuration is recommended on both
primary and recovery clusters. For more detail, refer to the Oracle 9i
RAC installation and configuration manual.
3. Configure ContinentalClusters. Follow the steps described in
this chapter to configure ContinentalClusters.
4. Configure Oracle 9i RAC instances in ServiceGuard
Packages. ContinentalClusters supports recovery only for
applications running in ServiceGuard packages. For details on how
to configure an Oracle 9i RAC instance in a ServiceGuard package,
refer to the Configuring OPS Clusters with Service Guard OPS
Edition manual.
In the ContinentalClusters environment, one Oracle 9i RAC instance
per ServiceGuard package is required. Configure the Oracle 9i RAC
instance packages on both primary and recovery clusters based on
