| Sumario: | This IBM Redbooks publication looks at the latest enhancements to WebSphere MQ for z/OS and shows how you can make use of the z/OS Parallel Sysplex to improve throughput and availability of your message-driven applications. It helps you configure and customize your system to use shared queues in a high-availability environment and to migrate from earlier releases. In the first part of the book, we provide an overview of z/OS Parallel Sysplex Technologies that you can integrate into your WebSphere MQ solution. We describe: - z/OS Resource Recovery Services (RRS) - Automatic Restart Manager (ARM) - Sysplex Distributor In the second part of the book, we introduce advanced features of WebSphere MQ for z/OS V5.3, namely the queue-sharing and clustering technologies. In the third part of the book, we describe our test implementation scenarios and cover the following topics: - Implementation of a queue-sharing environment - Migration from WebSphere MQ V5.2 - High-availability configurations - CICS, WebSphere MQ Integrator Broker, and IMS applications in a queue -sharing environment Finally, we look at the operational impact of a queue-sharing environment and discuss failure and recovery scenarios.
