It seems that not everyone knows this and it’s well worth knowing.

The default preferences for WMQ Explorer are to show progress dialogs for a minimum of 3 seconds. For example, when deleting a queue there is a progress dialog displayed saying “Deleting the object named MY_QUEUE”. You will always be waiting for 3 seconds before getting the “The object ‘MY_QUEUE’ was deleted successfully” message, even though the command itself was actioned in less than a second.

Given that you just asked for the queue to be deleted you might not want to artificially wait for 3 seconds.

Choose Windows -> Preferences and click on the “WebSphere MQ Explorer” folder to bring up the panel below.

Change the value from 3 to 0.

I’ve posted before about setting up WebSphere MQ Explorer as a read-only viewer using setmqaut and MCAUSER ids – a post which has proved quite useful to some readers.

A similar topic which seems to raise questions is using WebSphere MQ Explorer to administer remote queue managers where all server-connection channels are secured using SSL/TLS.

In this post, I will give some background about the issues surrounding using WMQ Explorer with SSL, and outline how it can be used with multiple queue managers.

There are often queries about using the WMQ Explorer from a desktop (without a WMQ install), to admin back-end queue managers.

If you have a back-end Windows installation of WMQ, RDC is a good option.
But what about when you’ve got a back-end Linux installation of WMQ?

Well, here’s an option:
Run the WMQ Explorer on the server, but using the X server of your desktop…

I had to migrate a Windows machine running WebSphere MQ v5.3 to WMQ v6 this evening. The WebSphere MQ Explorer on the machine was configured with client connections to a large number of remote queue managers that I needed to continue to be able to administer.

I didn’t realise that we don’t migrate queue manager connections when you go from WMQ v5.3 to the new Eclipse-based v6 WMQ Explorer. (Although I guess I can see why – they are very different apps). And I didn’t fancy the thought of having to manually enter each remote queue manager into Explorer one at a time after migration.

So I had a quick look at the ways that the different Explorers store their queue manager connection information, to see if it would be possible to convert between the two.

Refresh Pack 6.0.2.0 added some new plugins to the Eclipse-based WebSphere MQ Explorer. One of these is the “Tests plug-in”. The idea of the Tests plugin is to use the Eclipse ‘Problems View’ to display feedback about your WMQ configuration.

The “Tests plug-in” can itself be extended with user-written tests. This allows you to customize the WMQ Explorer so that it displays messages in response to any situation that you are interested in.

In this post, I’ll give a bit of background to the Tests plug-in, and walkthrough the steps involved in adding a new Test to the WMQ Explorer.

The WebSphere MQ Explorer GUI provides a user-friendly way to administer your queue managers.

With a little work, you can use it as a read-only ‘viewer’ instead. If you have some staff who don’t have authority to make changes to the WMQ network, but need them to be able to monitor what is happening, this would let them use WMQ Explorer to do it. If your staff without authority to make changes are the ones with less WebSphere MQ experience, then this might be a useful approach.

In this post I’ll walk through the steps required to set this up for a single queue manager, and highlight a couple of potential problems to watch out for.
