Sun Cluster 3.1 Data Services Developer's Guide

DSDL Overview

The DSDL API is layered on top of the RMAPI. As such, it does not supersede the RMAPI but rather encapsulates and extends the RMAPI functionality. The DSDL simplifies data service development by providing predetermined solutions to specific Sun Cluster integration issues. Consequently, you can devote the majority of development time to the high availability and scalability issues intrinsic to your application, and avoid spending a large amount of time on integrating the application startup, shutdown, and monitor procedures with Sun Cluster.
