9. Complete the remaining on-screen instructions to complete the installation.
Once the installation is complete, you must ensure that Oracle Clusterware is installed appropriately,
and that the Clusterware sub-cluster is formed. To ensure that Oracle Clusterware is installed
appropriately, check if the /opt/crs/oracle/product/10.2.0/crs/bin/crsd.bin and
/opt/crs/oracle/product/10.2.0/crs/bin/ocssd.bin processes are running on all
nodes in the current site.
To ensure that the Oracle Clusterware sub-cluster if formed, run the olsnodes -n command. This
command lists the nodes of the Oracle Clusterware sub-cluster. In this example, this command lists
the nodes of the SFO CRS sub-cluster.
olsnodes -n

SFO_2 2
Configuring SGeRAC Toolkit Packages for the site Oracle Clusterware Sub-cluster
To configure SADTA, the Clusterware daemons must be managed through Serviceguard. As a
result, the Clusterware sub-cluster at the site must be packaged using the SGeRAC toolkit. This
configuration must be done at both sites in the Metrocluster. Also, ensure that the package service
is configured to monitor the Oracle Clusterware.
For information on configuring the Clusterware packages, see the Use of Serviceguard Extension
for RAC Toolkit with Oracle 10g RAC manual available at http://www.hp.com/go/
hpux-serviceguard-docs.
SGeRAC toolkit packages can be created using the Package Easy Deployment feature available
in Serviceguard Manager version B.03.10. For more details, see Using Easy Deployment in
Serviceguard and Metrocluster Environments on HP-UX 11i v3 available at http://www.hp.com/
go/ hpux-serviceguard-docs —> HP Serviceguard.
Installing and Configuring Oracle Real Application Clusters (RAC)
The Oracle RAC software must be installed twice in the Metrocluster, once at each site. Also, the
RAC software must be installed in the local file system in all the nodes in a site.
To install Oracle RAC, use the Oracle Universal Installer (OUI). After installation, the installer
prompts you to create the database. Do not create the database until you install Oracle RAC at
both sites. You must create identical RAC databases only after installing RAC at both sites.
For information on installing Oracle RAC, see the documents available at the Oracle documentation
site. This section describes the high-level steps to install Oracle RAC.
Complete the following procedure to install Oracle RAC in the Metrocluster:
1. Start the Oracle Universal Installer from the temporary directory.
For example:
<Oracle Installation directory>/database/runInstaller
2. On the Specify Home Details screen, specify the local file system directory where the RAC
software will be installed on the site nodes.
3. On the Specify Hardware Cluster Installation Mode screen, select Cluster Installation and select
the nodes in addition to the local node.
4. On the Select Configuration Option screen, select the Install Database Software Only option.
5. Create a listener on both nodes of the site using Oracle NETCA.
For more information on using NETCA to configure listeners in a CRS cluster, see the Oracle
RAC Installation and Configuration user’s guide.
After installing Oracle RAC, you must create the RAC database.
