Oracle Solaris Cluster Data Services Developer's Guide

May 2011, Revision A

Title: Oracle Solaris Cluster Data Services Developer's GuidePart Number: 821-2848-10Audience: Experienced developers who have extensive knowledge of the software and hardware that is produced by Oracle Corporation.Page Count: 398Keywords: Oracle Solaris Cluster, Java, Agent Builder, DSDL, API, RMAPI, CRNPThis book describes the Oracle Solaris Cluster data service application programming interface (API). Developers can use this API to turn a standard user application, such as a web browser or database, into a highly available data service that can run in the Oracle Solaris Cluster environment.
