Notice: This SupportPac is now withdrawn and will be archived February 2016.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 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 might or might 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 objects are held on a queue manager that you have installed on a server machine.

Possible Uses
• Why use WebSphere MQ clients?
» 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 as follows:
- 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.
- Alternative channels using different transmission protocols may be used.

• What applications run on a WebSphere MQ client?
» Applications running within application servers that are certified as having passed the J2EE 1.4 (or later) Compatibility Test Suite can use the WebSphere MQ resource adapter provided in the SupportPac.
» The full MQI is supported in the client environment and this enables almost any WebSphere MQ application to be relinked to run on a WebSphere MQ client. Link the application on the WebSphere MQ client to the MQIC library, rather than to the MQI library. The exceptions are:
- An application that uses global transactions; that is, it requires sync point coordination with resource managers other than the queue manager.
- Get(signal) on z/OS.
» Applications which are built using various programming languages including C, C++, .NET (Windows systems only), COBOL, Java and JMS.
» Applications running within application servers that are certified as having passed the J2EE 1.4 (or later) Compatibility Test Suite can use the WebSphere MQ resource adapter provided in the SupportPac.

Note: An application running on a WebSphere MQ client may connect to more than one queue manager concurrently, or use a queue manager name with an asterisk (*) on an MQCONN or MQCONNX call. The application will have to be changed if you want to link to the queue manager libraries instead of the client libraries, as this function will not be available.

The IBM Message Service Clients offer C/C++ users an Application Programming Interface (API) that is consistent with the Java Message Service (JMS) API. Applications created using these clients can be used to exchange messages between other XMS applications, JMS applications or native WebSphere MQ applications and can  easily be migrated between WebSphere MQ, WebSphere Business Integration Message Brokers and WebSphere Application Server messaging environments with little or no rework.

Installation Instructions

To install a Unix Client:
1. Logon as root, create an empty directory (with sufficient space to receive the download file) and make it current.
2. Download mqc7_platform to this directory. (Where 'platform' replace with specific ie, AIX, HP-UX)
3. Execute uncompress -fv mqc7_platform.
4. Execute tar -xvf mqc7_platform.
5. Execute rm mqc7_platform.
6. Follow the instructions provided in the readme file to complete the installation of the client.

To install the client on a Windows machine download the zip file and extract the content. From the Windows subdirectory created run the setup.exe program.

Important information for Windows users
When upgrading the clients installation from previous levels to a WMQ V7.0.1.1 level, the mqclient.ini file in WebSphere MQ installation directory is removed. To overcome this problem, please take a backup of the mqclient.ini file from the WebSphere MQ installation directory (by default in C:\Program Files\IBM\WebSphere MQ) before upgrading the clients using the client installer, and copy it back after the install has completed.

More information about installing clients can be found in the WebSphere MQ Clients manual GC34-6590 which can be downloaded from the Product documentation.
