In this post, i will explain what is RFHUTIL, where to download it and how to use it.
RFHUTIL is a usefull tool to read, write and browse message located on a queue or subscribe, publish to a topic.
The tool can be downloaded here https://github.com/ibm-messaging/mq-rfhutil
From you command prompt, run the command line git clone https://github.com/ibm-messaging/mq-rfhutil.git
In the folder bin\Release, you will see two exe files rfhutil.exe and rfhutilc.exe

The difference between the two file is the connection method.
rfhutil.exe will connect to a local queue manager using local binding method.
