Ways to Create a Service That Uses the GDS

There are two ways to create a service that uses the GDS:

• Agent Builder

• Sun Cluster administration commands

GDS and Agent Builder

Use Agent Builder and select GDS as the type of generated source code. The user input is used to generate a set of scripts that configure resources for the given application.

GDS and Sun Cluster Administration Commands

This method uses the precompiled data service code in SUNWscgds. However, the cluster administrator must use Sun Cluster administration commands to create and configure the resource. See the clresource(1CL) man page.

Selecting the Method to Use to Create a GDS-Based Service

A significant amount of typing is required to issue Sun Cluster commands. For example, see How to Use Sun Cluster Administration Commands to Create a Highly Available Service That Uses the GDS and How to Use Sun Cluster Administration Commands to Create a Scalable Service That Uses the GDS.

Using the GDS with Agent Builder simplifies the process because the GDS generates the scripts that issue the scrgadm and scswitch commands for you.
