Abstract
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.
