This section describes how to configure Sun Cluster HA for Oracle extension properties.
For details on all Sun Cluster properties, see Appendix A, Standard Properties.
Typically, you configure extension properties by using the Cluster Module of Sun Management Center or the command line scrgadm -x parameter=value at the time you create the Oracle server and listener resources. You can also configure them later by using the procedures described in Chapter 9, Administering Data Service Resources.
Some extension properties can be updated dynamically and others only when the resource is created or when it is disabled. The Tunable column in the following two tables indicates when the property can be updated.
The required extension property for creating an Oracle listener resource is ORACLE_HOME. Table 2-3 describes the extension properties that you can set for the Oracle listener resource.
