Version 5.1 Enhancements - IBM AS/400e User Handbook Manual

The programs that comprise an MQSeries application can be running on different computers,
on different operating systems, and at different locations. The applications are written using a
common programming interface known as the Message Queue Interface (MQI), so that
applications developed on one platform can be transferred to another. When two applications
communicate using messages and queues, one application puts a message on a queue, and
the other application retrieves that message from the queue.
Queue Managers
In MQSeries, queues are managed by a component called a queue manager . The queue
manager provides messaging services for the applications and processes that the MQI calls
and the programs issue. The queue manager ensures that messages are put on the correct
queue or that they are routed to another queue manager.
Before applications can send any messages, you create a queue manager and queues.
MQSeries for Windows provides the utilities to assist with this and to create other MQSeries
objects that needed by applications.
Supported Platforms
MQSeries/400 supports a message exchange with other users of the MQSeries on over 35
IBM and non-IBM platforms. A complete list of supported platforms can be found on the Web
at:
http://www.ibm.com/software/mqseries/platforms
Client software provides a remote interface to a MQSeries server. There is no MQSeries
client of AS/400 currently available. If CICS for OS/400 is installed, MQSeries can
interoperate with CICS transactions and can link them with non-CICS environments.

Version 5.1 Enhancements

The enhancements for Version 5.1 of MQSeries include:
• Support for multiple queue managers
• Cluster (or groups) of queue managers
– Dynamically share workload
– Balance workload
– Reroute workload if a system component fails or network path becomes unavailable
• Administration of clusters of queue managers is easier and quicker
• Queue managers in the same cluster can be on different platforms or physically
remote from one another
