MQ v7.0.1 on z/OS and Security Exits

January 28, 2014 Roger Lacroix

If you are using MQ v7.0.1 on z/OS with a security exit (i.e. z/MQAUSX) and the SVRCONN channel’s attribute SHARECNV is greater than 0 then you may be experiencing a slow memory leak as given in the following IBM APAR (# PI08162):

MQAUSX Client-side Java Bug

January 22, 2014 Roger Lacroix

The following was recently reported:

For WebSphere Message Broker Toolkit, when the user inputs an incorrect password, the exit rejects the connection (as expected). If you try and connect again, you do not get a pop up prompting you for a new password attempt and the exit immediately ends the connection attempt.

If a user has connections to several Brokers open, with multiple frames open, they then have to close down and reopen everything.

It appears that WMQ Broker is reusing a Java security exit object after a failure. Normally, code simply re-instantiates the object. In this case, a flag was set incorrectly for reuse (after a failure). It has been fixed.

If anyone is having this particular issue with WMB Toolkit or any other WMQ product then send an email to support@capitalware.com and we will send you the latest release of MQAUSXJ.jar file.

IBM’s MQ Light

January 20, 2014 Roger Lacroix

I just found out about IBM’s new messaging product called MQ Light. IBM has made available an “alpha release” for Windows and Linux.
https://www.ibmdw.net/messaging/mq-light/

IBM® MQ Light provides a messaging runtime that developers can install, configure, and use to write applications in just a few minutes. MQ Light aims to enable developers to quickly create scalable and responsive applications. In a typical example, you might have an application that accepts web requests. MQ Light can provide messaging that enables the web request handlers to offload work to worker processes using a queue, so they can return to handle the next request immediately.

The MQ Concepts and API is located at:
https://www.ibmdw.net/messaging/mq-light/mq-light-concepts-api/

I’m trying understand where MQ Light fits into IBM’s big picture. Is it an MQTT implementation or something based on AMQP. So, I’m guessing that we would need some sort of bridge to have communication between MQ Light and WebSphere MQ (that’s just a guess).
