Question

What is RFHUTIL. What are the uses of it?

Answer 1

From the SupportPac IH03 page:

It allows test messages to be captured
and stored in files, and then used to
drive WBI Message Broker Version 7
applications. Output messages can also
be read and displayed in a variety of
formats. The formats include two types
of XML as well as matched against a
COBOL copybook. The data can be in
EBCDIC or ASCII. An RFH2 header can be
added to the message before the
message is sent.

WebSphere MQ messages can contain a Rules and Formatting Header or RFH for short. The RFHUtil (and it’s client-based companion RFHUtilc) allow for a wide variety of message manipulation with and without these headers. Because the headers are used extensively by WebSphere Message Broker and for v6 Pub/Sub the utility provides a convenient way to perform ad-hoc testing of message flows, publications and subscriptions. It also allows the loading and unloading of queues to files or files to queues, for example to perform regression testing against a known workload.
