Application Programmer Viewpoint

The SunPlex system provides data services for such applications as Oracle (on SPARC based systems), NFS, DNS, Sun^TM Java System Web Server (formerly Sun Java System Web Server), Apache Web Server (on SPARC based systems), and Sun Java System Directory Server (formerly Sun Java System Directory Server). Data services are created by configuring an off-the-shelf applications to run under control of the Sun Cluster software. The Sun Cluster software provides configuration files and management methods that start, stop, and monitor the applications. If you need to create a new failover or scalable service, you can use the SunPlex Application Programming Interface (API) and the Data Service Enabling Technologies API (DSET API) to develop the necessary configuration files and management methods that enable its application to run as a 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 failover or scalable data service.

• The Sun Cluster API, DSET 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.
