MQ Visual Edit and IBM MQ AMS

December 4, 2020 Roger Lacroix

The other day, an end-user contacted me saying that their MQAdmin had recently implemented IBM MQ AMS (Advanced Message Security) to some of their queue managers and that the end-user was having issues getting MQ Visual Edit working with those particular queue managers. Its too bad that the customer chose IBM MQ AMS over Capitalware’s […]

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 […]

I have decided to drop support for LZ1 compression algorithm from MQ Message Compression (MQMC) for the following reasons: LZ1 has the slowest compression […]
