What's Hot in the WebSphere MQ World?

I often find it interesting to look and see which of our WebSphere MQ technotes are getting the most references within problem records. It is a good way to keep on top of what the hot issues or concerns are for the MQ world. It is quite common to find the Must Gather related technotes at the top of the list every time I look. This is not surprising. The Must Gather technotes are the backbone of the support structure. They provide instructions on what documentation to gather for different problem scenarios and instructions on how to collect that documentation. They are referenced in a large number of the problem records.
There are other things, like the technotes for system requirements or the technotes that give the instructions for downloading our fixes that are also always at the top of the list. Again, it is no surprise to see them in the top of the list but where it gets more interesting is when we start looking to see what other technotes are being referenced.
I checked to see what the most referenced technotes were for March, April and May 2012 Now I want to share the top 10 technotes (other than the Must Gather or Download and Reference items).
10. Upgrade the MQ trial version to a production version
This one tends to be more popular as the end of support approaches for a version of MQ and MQ v6 goes out of support in September 2012.
9. Cold Start Procedure for WebSphere MQ for iSeries
This item appears in the top 10 frequently but please note that it is unique to only the iSeries platform. It does not translate to the other platforms. You would typically only use a cold start procedure in rare and extreme circumstances.
8. WMQ 7.1 queue manager - RC 2035 MQRC_NOT_AUTHORIZED when using client connection as an MQ Administrator
Due to some changes in MQ security in version 7.1, this is a popular topic right now. This item addresses one of the more common security related issues that MQ v7.1 users are encountering.
7. AIX 32-bit program gets reason code 2102 (MQR
Although this one is unique to the AIX platform, it still gets a lot of action. If you are having system resource related problems on AIX, this is a great place to start investigation of that situation. Also, you should keep reading because item number one will be of some interest to you as well.
6a. Information about using WebSphere MQ as the JMS Provider for WebSphere Application Server Version 6.1
6b. Information about using the WebSphere MQ messaging provider for WebSphere Application Server Version 7.0
Number 6 in my list is actually two separate items that both showed up near the top of the list of most referenced items. They provide similar information but, as you can see from the titles, one is for WebSphere Application Server v6.1 and the other for v7.0. Either one of these items would have made it into the top ten list as a single item.
5a. Testing and support statement for WebSphere MQ multi-instance queue managers
5b. Testing a shared file system for compatibility with WebSphere MQ Multi-instance Queue Managers
Here is another two for one bargain. We had 2 items on Multi-instance queue managers in the list of top references but I combined them into one item for this list. This is a new feature in MQ v7 and it is something a lot of customers had been requesting for a while so it is a very popular topic right now.
4. CSQX208E TRPTYPE=TCP RC=00000461 or AMQ9208 10054
This item talks about the very common problem of connection reset by peer. MQ is very good about reporting when the problem occurs but MQ is typically not the cause of the problem. Unfortunately, the bearer of the bad news (MQ) is often blamed until it has been determined where the problem actually occurred. This item helps lay out where to find the real cause of this problem.
3. MS03: WebSphere MQ - Save Queue Manager object definitions using PCFs (saveqmgr)
This is one of the all time most popular SupportPacs for MQ. The functionality provided by this SupportPac has been greatly appreciated by customers for years. One bit of good news is that much of this functionality was added into the WebSphere MQ product in version 7.1.That is one more reason to migrate to MQ v7.1 if you have not done so yet.
2. WebSphere MQ Support, Migration PTFs
Much like item 10, listed previously, this is an item that grows in popularity when a version of MQ is approaching the end of it's support. If you are still running with WebSphere MQ v6, you should get moving on migrating to a supported version soon. You do not want to wait until you are out of support and then have to deal with extended support contracts or having a production system outage when you are out of support.
1. How to configure UNIX and Linux systems for WebSphere MQ
This item has been around for a while but recently was updated with some new improvements. If you have not looked at this one lately, you may find the updates interesting. If you are configuring a new system for MQ, you definitely can save yourself some time and some potential problems by using the tools provided in this item.
That concludes this top 10 list. I hope you found it interesting and helpful. If you are seeing some other issues or topics that you think should be included, please let me know and I will try to spread the word about them as well.
