Limitations of the MQ binding

The MQ binding has some limitations in its use that are listed here.

No publish-subscribe message distribution

The publish-subscribe method of distributing messages is not currently supported by the MQ binding though WMQ itself supports publish-subscribe. However, the MQ JMS binding does support this method of distribution.

Only MQ client connections are supported

MQ client connections are the only type of connections supported.

Channel compression is not supported

Channel compression, which compresses the data that flows on a WebSphere MQ channel to improve performance, is not supported.

Limited support of headers

WebSphere MQ headers have specific data types and parsers for them determine the data type of each field in the header. The MQ bindings currently provide support for the MQRFH and MQRFH2 header.

Serialize as Java Object data format

The Serialize as Java Object serialization type can only serialize business objects; that is, an interface operation must have its input(s) and output(s) defined as a business object type. An interface operation cannot be defined with primitive types for input and output. The following operation, for example, is not allowed.
Operation defined with primitive type inputs and outputs
