Data Service API and Data Service Development Library API

Sun Cluster provides the following to make applications highly available:

• Data services supplied as part of Sun Cluster

• A data service API

• A data service development library API

• A "generic" data service

The Sun Cluster 3.0 Data Services Installation and Configuration Guide describes how to install and configure the data services supplied with Sun Cluster. The Sun Cluster 3.0 Data Services Developers' Guide describes how to instrument other applications to be highly available under the Sun Cluster framework.

The Sun Cluster API and Data Service Development Library API 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, Sun Cluster 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 highly available data service.
