Application Developer View

The Sun Cluster software provides data services for such applications as Oracle, NFS, DNS, Sun Java System Web Server, Apache Web Server (on SPARC based systems), and Sun Java System Directory Server. Data services are created by configuring 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 Sun Cluster 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 Development

Application developers 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. Developers 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.
