I think we are well over due for a new update on What's Hot in the WebSphere MQ World. It is Spring time here in the United States and several things have been springing up in the WebSphere MQ world lately. I think now is a good time to talk about a few of them.
1. How the TLS Heartbleed security vulnerability applies to WebSphere MQ offerings.
This topic has been a hot item recently for most all companies. Whether this vulnerability actually affects a product or not, it is still a hot topic, even if it is just a matter of letting folks know that it does not affect the product. For most platforms and libraries it was the case that MQ was not affected, but there were a few of the client libraries that were affected. There is a security bulletin that discusses the specifics of which client libraries were affected:

For details on how the Heartbleed security vulnerability applies to other IBM offerings you can refer to the
IBM Product Security Incident Response Blog
2. Where's my message?
Peter Broadhurst summed up this topic quite well when he wrote "Working out what happened to 'lost' messages is a topic that comes up frequently in my conversations with customers (we all know they're not really lost of course)." "I'm afraid I don't have a magic bullet for all cases, but for your critical persistent messages on distributed platforms there is one great source of information you might not have looked at before - the MQ recovery log."
Peter has written a very handy tool to assist you in finding out what happened with your messages by reviewing the MQ recovery log. Here is a blog where Peter introduces the tool:
Where's my message?
and a technote that goes into a bit more detail and provides a download link for the tool.

3. Load Balancing in WebSphere MQ
There are quite a few different aspects to consider and quite a few different ways to go about load balancing your messages in WebSphere MQ and there have been a number of different things written and said on the topic recently.
4. IBM MessageSight
The IBM MessageSight product has been getting a lot of attention lately. Mobile is really one of the hot spots in the business world today and MessageSight is a great way to connect those millions of mobile devices into your existing WebSphere MQ networks. Valerie Lampkin will be presenting a webcast which helps explain MessageSight much better and that webcast is Scheduled for 23 April at 11Am EDT. (Note this was originally planned to be presented on 09 April but had to be rescheduled due to technical difficulties.)
Using MQTT for connection of mobile applications to IBM MessageSight and enterprise messaging systems
Valerie also was a big part of the team that produced the IBM Redbooks publication:
Responsive Mobile User Experience using MQTT and IBM MessageSight
as well as another related publication,
Building Smarter Planet Solutions with MQTT and IBM WebSphere MQ Telemetry
(Now I am reconsidering my blog title again. Perhaps it should be "What's Hot in the worlds of Peter and Valerie?")
5. The Knowledge Center Beta
The IBM documentation teams have been hard at work for quite a while now to redesign the way we present our online documentation, not just for WebSphere MQ but for most IBM documentation. The new format is called the Knowledge Center and the Beta version of the Knowledge Center was made available for everyone to look over and play with at the start of this year. If you have not looked over the Knowledge Center yet, I would encourage you to take a look and see what you think.
Here is a link to the welcome page for MQ in the Knowledge Center.
There is also a pretty handy help page to explain a little more about several of the great new features in Knowledge Center:
