Application Programmer Viewpoint

Sun Cluster provides several highly available data services for such applications as Oracle, NFS, DNS, iPlanet Web Server, Apache Web Server, and Netscape Directory Server.If a site has to make another application run on a cluster, it can use the Sun Cluster Application Programming Interface (API) and the Data Service Development Library API (DSDL API) to develop the necessary data service software that enables its application to run as a highly available data service on the cluster.

Key Concepts - Application Programmer

Application programmers need to understand the following:

• The characteristics of their application to determine whether it can be made to run as a highly available or scalable data service.

• The Sun Cluster API, DSDL API, and the "generic" data service. Programmers need to determine which tool is most suitable for them to use to write programs or scripts to configure their application for the cluster environment.
