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 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 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:
- 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?
» 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 JEE 7 Compatibility Test Suite can use the WebSphere MQ resource adapter provided in the SupportPac. For more information see WebSphere MQ resource adapter v8.0 statement of support

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 is not available.

The IBM Message Service Client offers C/C++ users an Application Programming Interface (API) that is consistent with the Java Message Service (JMS) API. Applications created using this client can be used to exchange messages between other XMS applications, JMS applications, or native WebSphere MQ applications.

Managed File Transfer (MFT) code is not provided in this SupportPac.

IBM has withdrawn the download of the MQ Client for HP NonStop Server. As IBM has stated in a Statement of Direction ( there is an intent to deliver an updated version of IBM MQ for the HP NonStop Server platform as this should be a better solution to meet the MQ connectivity needs for most customers on the HP NonStop Server platform. In common with other IBM MQ platforms, MQ Clients that run on other platforms will continue to provide connectivity to IBM MQ Servers on the HP NonStop platform and other MQ Server supported platforms.

To gain an early look at the intended release of IBM MQ V8 for HP NonStop Server please join the beta program by contacting your IBM sales representative.

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 mqc8_platform to this directory. (Where 'platform' is replaced with a specific platform name e.g. AIX, Linux-x86)
3. Uncompress mqc8_platform.
4. Execute tar -xvf mqc8_platform.
5. Execute rm mqc8_platform.
6. Follow the instructions provided in the WebSphere MQ v8 Information Center 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.
