Changing Channels
Every so often, I share a blog about our social support program and what's happening with our social media channels . I have a few things to share today, for which I'm really excited. Firstly, I have moved into the role of Manager, for Social Support Enablement for the Cloud Technical Support Organization. Secondly, our new Social Business Program Manager, is @Kim McCall , who you may remember from some of her posts on DataPower. We're looking to continue the efforts we've undertaken in sharing...

A better, stronger and faster WebSphere MQ on z/OS
WebSphere MQ implements more enhancements and improvements with each new version that is released. While major changes receive a lot of fanfare through topics in the IBM Knowledge Center, there are often many behind-the-scenes updates that aren't as major, but still greatly enhance MQ. Sometimes the code is just tightened up a bit or (for MQ on z/OS) service parameters are implemented to help mitigate undesired behavior. Here, we will take a look at some of these changes, code enforcements, and service parameters that Level 2 cites... [More]

MQ version 8 Redbooks Publication Coming Soon!
As an IBMer supporting WebSphere MQ I have always been intrigued by the place known as the Hursley Lab, located in the UK. Finally, on my 15 year anniversary as an IBM employee I set off on a trip to visit the place where MQ is developed. I felt somewhat like Charlie going to visit the Chocolate Factory. I was thrilled to be chosen to participate in an IBM Redbooks residency for publishing a book which will provide information about the MQ version 8 enhancements. MQ V8 was made available in June 2014 and contains many improvements... [More]

Avoiding run-away numbers of channels
As an administrator of a WebSphere MQ Queue Manager, you have the job of ensuring that the system runs smoothly and that a badly behaving application cannot have an impact on other users of the queue manager. One of the ways you ensure this happens is to restrict the number of channels that can run, thus avoiding problems when too many channels use up resources on the system, such as memory. Traditionally this was done by setting a value for the overall queue manager that set a maximum on the number of channels that could be run in the... [More]

WebSphere MQ Channels waiting on Domain Name Server
We see the problem mentioned in the title "WebSphere MQ Channels waiting on Domain Name Server" quite often in Websphere MQ Level 2 Support. It manifests itself in a variety of ways: You notice that channels are very slow to start or end. Sometimes you will see the message, CSQX014E, meaning that there are more channels trying to start than you have defined with MAXCHL. You may see many CSQX500I messages. If you display channel status, DISPLAY CHSTATUS, you see channels in STATE(BINDING) and SUBSTATE(NAMESEVER). If you do multiple... [More]

Triggering Channels
In my " Triggering for beginners " blog entry the focus was triggering user programs. This is a follow-up with details for triggering channels. If you didn't see that post, then I suggest you read it before continuing. Triggering is essentially the same for triggering programs and triggering channels, however there are some important differences. Triggering WebSphere MQ channels is much easier than triggering programs: you don't need to start a trigger monitor, because the Channel Initiator is a special purpose trigger monitor that... [More]
