MQ configuration sends random text as header in the request



After changing the application server from WebSphere Application Server to WebSphere Application Server Liberty, an RFH header is added to the Message Queue (MQ) request message.

Error Messages

Not Applicable

Steps to Reproduce

  1. Install Pega 7.4 on WebSphere Application Server Liberty.
  2. Configure the MQ using JNDI Lookup.
  3. Send the request.

Root Cause

The server added the MQ header, not the Pega application. Therefore, the header in the message body did not display in the Clipboard or the PegaRULES log. If the message is sent as a string (MQSTR), the RFH header is not added to the message body.


Perform the following local-change:
  1. On the WebSphere Application Server Liberty server, open the server.xml file for editing.
  2. In the jmsQueue tag, add the attribute targetClient="MQ".
