When a message is received by an input node in a message flow, the node detects how to interpret that message by determining the domain in which the message is defined and invoking the appropriate parser.
You can provide message domain information to the input node in one of two ways:
If the input message is defined in the MRM domain, and is therefore interpreted by the MRM parser, you must specify the following additional properties:
If the message is a WebSphere MQ message, these properties can be set either in the input node or in the MQRFH2 header of the incoming message. If they are set in both, the contents of the MQRFH2 header take precedence.
If the input message belongs to a message domain other than those for which a parser is supplied, you must provide a user-defined parser to handle it, and a user-defined input node to accept it for processing in the message flow. Check the documentation provided with the user-defined parser and node for further information.
If the input node cannot determine the message characteristics, the message is considered to be in the BLOB domain, and the BLOB parser is started.
