Building Disaster Recovery Serviceguard Solutions Using Metrocluster with 3PAR Remote Copy
This command starts the Oracle Universal Installer graphical user interface. Ensure that the
DISPLAY environment variable is set appropriately.
5. Provide appropriate values at each screen until you reach the Specify Cluster Configuration
screen.
6. On the Specify Cluster Configuration screen, do the following:
a. Select only nodes that belong to the current site.
b. Specify the site-specific Clusterware name as the Cluster Name.
In this example, for the SFO Clusterware sub-cluster, select only the San Francisco site
nodes SFO_1 and SFO_2. Do not include any other nodes. Specify the Clusterware
sub-cluster name as sfo_crs.
7. In the Specify Oracle Cluster Registry (OCR) Location screen, select External Redundancy and
specify the CFS file system directory if you have an independent backup mechanism for the
OCR.
To use the internal redundancy feature of Oracle, select Normal Redundancy and specify
additional locations.
In this example, for the SFO Clusterware sub-cluster, the location is specified as:
/cfs/sfo_crs/OCR/ocr
8. On the Specify Voting Disk Location screen, select External Redundancy and specify the CFS
file system directory if you have an independent backup mechanism for the Voting Disk.
To use the internal redundancy feature of Oracle, select Normal Redundancy and specify
additional locations.
In this example, for the SFO Clusterware sub-cluster, the location is specified as:
/cfs/sfo_crs/VOTE/vote
9. Follow the remaining on-screen instructions to complete the installation.
After the installation is complete, 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_1 1
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 RAC 10g Release 2 or later manual available at http://www.hp.com/
go/hpux-serviceguard-docs ->HP Serviceguard Extension for RAC.
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.
