Request & Reply JMS/MQRFH2 Messaging Scenario

January 31, 2020 Roger Lacroix

Sometimes people over think a problem and write a complicated solution when really the solution is no different than any other Request/Reply scenario (use case). On StackOverflow, someone asked a question about sending a reply JMS/MQRFH2 message using the RFH2 header and folder values from the original request message. The code will copy the RFH2 […]

JMS/MQRFH2 Message Properties in “other” Folder

January 17, 2020 Roger Lacroix

On StackOverflow, someone asked about having an “other” folder (not “usr”) with an MQRFH2 (aka JMS) message. That day, I played around with a MQ/Java program that created various folders in an MQRFH2 message. i.e. When I ran a MQ/JMS program to retrieve the messages, the MQ/JMS programs simply ignore all folders outside of ‘mcd’, […]

Late last week, a customer discovered an obscure issue in MQ Message Encryption (MQME) with the ExcludeQueue keyword on an MQPUT1 API call. I have since fixed it but here is what I mean by obscure: – If the user has wild-carded their protected queue setup i.e. ‘TEST.*’ – And then set the ExcludeQueue keyword […]

Customer Requested Update to MQ Message Encryption

November 21, 2019 Roger Lacroix

MQ Message Encryption (MQME) is a solution that provides encryption for MQ message data while it resides in a queue or topic and in the MQ logs (i.e. data at rest). By default, when an application puts a message to a protected queue, MQME will encrypted the entire message data. If the application is putting […]

Doug posted a question on MQ List Server regarding the MQ error message AMQ7234. His question was: My shop has always struggled with large number of messages just being left on the queue. Sometimes to be processed later, sometimes because the application does not know what to do with them, but they cannot be removed. […]
