Accessing headers

If the input message received by an input node includes message headers that are recognized by the input node, the node invokes the correct parser for each header. Parsers are supplied for most WebSphere MQ headers. The topics listed below provide some guidance for accessing the information in the MQMD and MQRFH2 headers, which you can follow as general guidance for accessing other headers also present in your messages.

Every header has its own correlation name, for example, MQMD, and you must use this in all ESQL statements that refer to or set the content of this tree:

For further details of the contents of these and other WebSphere MQ headers for which WebSphere Message Broker provides a parser, see Element definitions for message parsers.
