Unable to create JMS MDB listener



Unable to create Java Messaging Service (JMS) Message Driven Bean (MDB) listener with WebLogic 12c application server.
The connection factory, JMS server, JMS module and topic are created (according to the Pega platform 7.31 installation guide). However, while producing the JMS MDB Jar file from the integration resource, the Test Connectivity option is disabled.
The Pega application is unresponsive and multiple errors occur on Application server console and PegaRules log.

Error Messages

  1. ERROR - Exception occurred while checking disk space on pulse.
  2. java.lang.OutOfMemoryError: GC overhead limit exceeded

Steps to Reproduce

Follow the instructions listed in the 'Deploying a JMS message-driven bean (MDB) that represents a JMS MDB listener in Pega 7' article to create the JMS MDB.
Refer to:

Root Cause

The T3 protocol was not enabled in the WebLogic server which the JMS hasd to use for communication.


As a local-change, enable the T3 protocol from the Administrator server.
