The GDS has the following advantages over using either the SunPlex Agent Builder generated source code model (see scdscreate(1HA)) or the standard Sun Cluster administration commands:
The GDS is easy to use.
The GDS and its methods are precompiled and are therefore not modifiable.
The SunPlex Agent Builder can be used to generate driving scripts for your application and these scripts are packaged in a Solaris-installable package that can be reused across multiple clusters.
