3. Run the following command to apply the configuration file:
# cmapplyconf -v -C /etc/cmcluster/dbcluster.config
4. Run the following command to start the cluster:
# cmruncl
After you start the cluster, run the cmviewcl command to view the site configuration.
Configuring the CFS Multi-node Package (SMNP)
If Cluster File System (CFS) is configured in the environment, configure the Serviceguard CFS (SG
CFS) package. To create an SG CFS SMNP package (SG-CFS-pkg), run the cfscluster command.
After creating the package, ensure that there are two CFS sub-clusters in the Metrocluster.
Run the following command on any node, at both sites, to view the list of nodes and the status of
each node:
# cfscluster status
The following output is displayed:
Node : SFO_1
Cluster Manager : up
CVM state : up (MASTER)
Node : SFO_2
Cluster Manager : up
CVM state : up
Installing and configuring Oracle Clusterware
After you set up replication in your environment and configure the Metrocluster, install Oracle
Clusterware. Use the Oracle Universal Installer to install and configure the Oracle Clusterware.
SADTA requires two Oracle Clusterware sub-clusters, one at each site, therefore you must install
and configure Oracle Clusterware twice in the Serviceguard cluster.
When you install Oracle Clusterware at a site, the sub-cluster installation is confined to a site and
the Clusterware storage is not replicated. As a result, Oracle Clusterware must be installed on a
local file system at each node in the site. The Oracle Cluster Registry (OCR) and Voting disks must
be shared only among the nodes in the site. In this example, CFS is shared between the site nodes
for the OCR and Voting disks.
Install Oracle Clusterware, one site at a time. The following sections describe the procedure to
install and configure Oracle Clusterware sub-cluster at both sites.
Configuring the Network
To configure the network:
1. Identify the Oracle virtual IP and private IP to be used in the site Clusterware sub-cluster and
enter them in the /etc/hosts file on all the nodes in the site. All nodes in the site CRS
sub-cluster must be able to resolve the private and virtual IP of all other nodes in the site CRS
sub-cluster.
In this sample configuration, for the SFO CRS sub-cluster, the following entries must be made
in the /etc/hosts file of SFO_1 and SFO_2 nodes.
