This SupportPac contains the IBM WebSphere MQ client components for VSE.
Notice: This SupportPac is now withdrawn and will be archived on 1 February 2016.
A WebSphere MQ client is part of the product that can be installed on its own, on a separate machine from the base product and server. You can run a WebSphere MQ (MQSeries) application on a WebSphere MQ client and it can interact, by means of a communications protocol, with one or more WebSphere MQ servers and connect to their queue managers. The servers to which the client connects may or may not be part of a cluster. WebSphere MQ Family Platforms provides a list of which platforms are supported as WebSphere MQ Clients and/or Servers.
An application that you want to run in the WebSphere MQ client environment must first be linked with the relevant client library. When the application issues an MQI call, the WebSphere MQ client code directs the request to a queue manager, where it is processed and from where a reply is sent back to the client. The link between the application and the client code is established dynamically at runtime.
The MQI is available to applications running on the client platform; the queues and other WebSphere MQ (MQSeries) objects are held on a queue manager that you have installed on a server machine.
Using WebSphere MQ clients is an efficient way of implementing WebSphere MQ messaging and queuing. You can have an application that uses the MQI running on one machine and the queue manager running on a different machine, either physical or virtual. The benefits of doing this are:
» There is no need for a full WebSphere MQ implementation on the client machine.
» Hardware requirements on the client system are reduced.
» System administration requirements are reduced.
» A WebSphere MQ application, running on a client can connect to multiple queue managers on different systems.
Skill Level Required
This SupportPac is intended for anyone who installs and configures MQSeries products for the client-server environment, and for application programmers who write programs to make use of the Message Queue Interface (MQI).
New in this Release
This is a new release.
The WebSphere MQ Client for VSE is expected to function in conjunction with the MQSeries for VSE V2.1 product, as well as WebSphere MQ versions 5.3 and 6.0 that support client attachment.
The readme file included in this SupportPac provides details of how the MQ Client for VSE differs from version 5.3 and 6.0 clients.
