Data Service API and Data Service Development Library API

The SunPlex system provides the following to make applications highly available:

• Data services supplied as part of the SunPlex system

• A data service API

• A data service development library API

• A “generic” data service

The Sun Cluster 3.1 Data Service Collection describes how to install and configure the data services supplied with the SunPlex system. The Sun Cluster 3.1 Data Services Developer's Guide describes how to instrument other applications to be highly available under the Sun Cluster framework.

The Sun Cluster APIs enable application programmers to develop fault monitors and scripts that start and stop data services instances. With these tools, an application can be instrumented to be a failover or a scalable data service. In addition, the SunPlex system provides a “generic” data service that can be used to quickly generate an application's required start and stop methods to make it run as a failover or scalable service.
