There are two ways to create a service that uses the GDS:
Using the SunPlex Agent Builder
Using the standard Sun Cluster administration commands
Use the SunPlex 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.
This method uses the precompiled data service code in SUNWscgds but requires that the system administrator use standard Sun Cluster administration commands to create and configure the resource. See the scrgadm(1M) and scswitch(1M) man pages.
As shown in the procedures 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, a significant amount of typing is required to issue the appropriate scrgadm and scswitch commands.
Using GDS with SunPlex Agent Builder simplifies the process because it generates the scripts that issue the scrgadm and scswitch commands for you.
