Customize Applications for Maximum Availability in Sun Cluster EnvironmentsThe Sun Cluster 3 environment offers developers and administrators a powerful API for creating custom "data services" that maximize the availability and enhance the horizontal scalability of many enterprise applications. Now, here's an authoritative tutorial and reference to building custom data services with the Sun Cluster 3 API. In Sun Cluster 3 Programming, three leading Sun Cluster experts systematically review the tools, programming interfaces, and features that make custom data services possible. Then, through a series of step-by-step examples, they demonstrate how to ensure that applications can recover smoothly from even the most serious failures.This bookReviews every facet of "availability" and what it takes to make software availableProvides extensive easy-to-understand code examples, all available for downloadCovers all areas of agent development, from quick basics to advanced techniquesCovers all the APIs provided with Sun Cluster 3Walks step-by-step through making existing applications available, scalable, and cluster-awareUntil now, this information has been available only in a three-day Sun training course.
Now, with the help of Sun's in-house experts, you have all the information you need to build Sun Cluster 3 custom applications that deliver unprecedented levels of application availability.
