The Device Group Monitor can also be configured in this Site Controller package. For
more information on the 3DC parameters and Device Group Monitor configuration, see
“Configuring Primary Packages in the Primary Cluster using the 3DC Modules ” (page 442).
3. Apply the empty Site Controller Package configuration file in the recovery cluster.
# cmapplyconf -P /etc/cmcluster/hrdb_sc/hrdb_sc.config
IMPORTANT: Ensure there are no packages configured with the critical_package or
managed_package attributes in the Site Controller Package configuration file. These attributes
must be configured only after configuring the Site Safety Latch dependencies as described in the
section “Configure Site Safety Latch Dependencies for a RAC database in the recovery cluster” of
this document
Configuring Site Safety Latch Dependencies in the Primary Cluster
After the Site Controller Package configuration is applied, the corresponding Site Safety Latch is
also configured automatically in the cluster. The Site Safety Latch dependencies must be configured.
For more information on configuring these dependencies in the primary cluster, see “Configuring
the Site Safety Latch Dependencies”.
Configuring Oracle RAC and the Site Controller Package in the recovery cluster
This section describes the procedures to configure Oracle RAC and the Site Controller Package in
the recovery cluster. Following are the topics discussed in this section:
1. Configuring Oracle RAC in the recovery cluster
2. Configuring the Site Controller Package in the recovery cluster
3. Configuring the Site Safety Latch Dependencies in the recovery cluster
Configuring Oracle RAC in the recovery cluster
After Oracle RAC is configured in the primary cluster, Oracle RAC must be configured in the
recovery cluster as well. First, install and configure Oracle Clusterware and Oracle RAC software.
Then, setup a RAC database in the recovery cluster using the replicated disks. This section discusses
the following topics:
1. Install and configure Oracle Clusterware in the recovery cluster
2. Install and configure Oracle RAC in the recovery cluster
3. Setup a RAC database in the recovery cluster using the replicated disks
Install and configure Oracle Clusterware in the recovery cluster
After configuring the recovery cluster, you must install Oracle Clusterware in the recovery cluster.
Use the Oracle Universal Installer (OUI) to install and configure the Oracle Clusterware on all
nodes in the recovery cluster. For information on installing and configuring Oracle Clusterware,
see section “Installing and Configuring Oracle Clusterware” (page 369).
After Oracle Clusterware software is installed, configure SGeRAC Toolkit Packages for the Oracle
Clusterware in the recovery cluster. For information on configuring the Clusterware packages, see
the Use of Serviceguard Extension for RAC Toolkit with Oracle RAC 10g Release 2 or later document
available at http://www.hp.com/go/hpux-serviceguard-docs —> HP Serviceguard Extension for
RAC.
Install and configure Oracle RAC in the recovery cluster
After installing Oracle Clusterware, the Oracle RAC software must be installed in the recovery
cluster. To install Oracle RAC, use the Oracle Universal Installer (OUI). For information on installing
