Another Useful Feature of runmqsc

November 27, 2020 Roger Lacroix

I was reading the MQ Knowledge Center today (surprising, yes, I know!) looking up whether or not runmqsc in client mode uses regular PCF commands when sending commands to a remote queue manager. It doesn’t. It uses escaped PCF messages. Anyway, I stumped across an interesting new feature that IBM included in IBM MQ v8.0 […]

C Code to Lookup MQ Reason Code

November 16, 2020 Roger Lacroix

Starting with the release of IBM MQ v8.0, IBM included a new header file called: cmqstrc.h. The file description says: This file provides mappings between MQI constant values and string versions of their definitions. In the cmqstrc.h file, from IBM MQ v9.2, there are 342 subroutines for looking up the various integer values and returning […]

Withdrawn/Discontinued: IBM IoT MessageSight and IBM Watson IoT Platform – Message Gateway

November 4, 2020 Roger Lacroix

I just came across the following announcement that says IBM has completely pulled the plug on IBM IoT MessageSight and IBM Watson IoT Platform – Message Gateway. https://www.ibm.com/support/pages/node/6340723 So basically, that leaves IBM MQ as IBM’s primary messaging platform for MQTT? It is rather odd since IBM has refused to fully support MQTT in IBM […]

Dropping LZ1 support from MQ Message Compression

September 21, 2020 Roger Lacroix

I have been doing a lot of a testing of various messages types (i.e. Fixed-width, CSV, XML, JSON, PDF, PNG, JPG, etc.). I’ll post the results in the next blog posting. I have decided to drop support for LZ1 compression algorithm from MQ Message Compression (MQMC) for the following reasons: LZ1 has the slowest compression […]
