Planning the Sun Cluster Geographic Edition Environment

This section provides guidelines for planning and preparing the following components for Sun Cluster Geographic Edition software installation:

• Licensing

• Logical Hostnames

Licensing

Ensure that you have available all necessary license certificates before you begin software installation. Sun Cluster Geographic Edition software does not require a license certificate. However, each node that is installed with Sun Cluster Geographic Edition software must be covered under your Sun Cluster Geographic Edition software license agreement.

For licensing requirements for data replication software and application software, see the installation documentation for those products.

Logical Hostnames

Sun Cluster Geographic Edition software uses the logical hostname of a cluster for inter-cluster management communication and heartbeat communication. The IP address for a cluster name must be available for Sun Cluster Geographic Edition software to wrap a logical hostname around the IP address when the software is started by using the geoadm start command.

You can use the cluster command to find the name of the cluster when you need to verify that the cluster name is suitable for use as a hostname. To find the name of the cluster, run the following command:

# cluster list

For more information, see the cluster(1CL) man page.
