Identifying Data Service Special Requirements

Identify requirements for all of the data services before you begin Solaris and Sun Cluster installation. Failure to do so might result in installation errors that require that you completely reinstall the Solaris and Sun Cluster software.

For example, the Oracle Parallel Fail Safe/Real Application Clusters Guard option of Sun Cluster Support for Oracle Parallel Server/Real Application Clusters has special requirements for the hostnames that you use in the cluster. Sun Cluster HA for SAP also has special requirements. You must accommodate these requirements before you install Sun Cluster software because you cannot change hostnames after you install Sun Cluster software.Also note that both Sun Cluster Support for Oracle Parallel Server/Real Application Clusters and Sun Cluster HA for SAP are not supported for use in x86 based clusters.
