Retiring SupportPac MS0P

SupportPac MS0P was first released in 2006. It added a plugin to the MQ Explorer to format event messages, including the accounting and statistic information. Since then, there’s been a lot of added function. But also, the MQ product now has a lot of comparable capability. The last functional update to MS0P was in 2018.

I’m not planning on making any further updates to the package, so I’ve been thinking about retiring it. The recent LTS release of MQ 9.4.0 seemed like a good boundary point to do that. The SupportPac will move to “withdrawn” status – still downloadable, but not as prominent.

But I thought it worth listing the various features, and showing how many of them you can now do differently.

MQ Spring Boot: Advanced Configuration and Transactions

I was talking recently with an MQ customer who said they were considering a solution that used Spring Boot for an MQ application that would move messages reliably from one queue manager to another, doing some processing on the way. “Can we do that?” they asked. “Of course” was my reply. But naturally I had to then try it out myself.

To implement the idea, I had to dig into two aspects. I’d consider these as reasonably advanced features of Spring Boot. One part was being able to configure more than one queue manager’s connection in the resource properties file. The other was working with global JTA/XA transactions.

MQ Metrics with OpenTelemetry

As I promised in a recent article, I am coming back to the OpenTelemetry topic. This time, it’s going to be about another pillar of the observability requirements – integrating MQ’s metrics with OpenTelemetry.

Handling MQ logs and events with OpenTelemetry

One recent addition to the plethora of observability tools is OpenTelemetry. It attempts to provide a vendor-agnostic set of common APIs, components, interfaces and protocols that enable interoperability between a range of other tools. It deals with three major pillars of telemetry data, the things you often need to look at when monitoring systems: traces (by which it means application-level data flows), metrics, and logs.

There are already ways of tracking messages through an MQ network and beyond, reporting via OpenTelemetry. And I will soon be talking a lot more about MQ metrics and OpenTelemetry. But as an appetiser, this post shows the third piece of the story: logs.

MQ JMS and Spring: Spring Boot 2 now at end of regular support

Spring Boot 2 has now reached its “end of non-commercial support“. The lifecycle for that project is set by Spring’s owners; a major release typically has 2 years of open support before moving into a longer-term paid-for regime.

MQI Node.js library: an experimental reimplementation

The MQI library for Node.js applications first appeared in 2017. One of the first articles about it is here. Regular maintenance and updates to the library ensured it kept up with newer MQ and NodeJS features. But it seemed time to do a more extensive rewrite of the package, and that’s why I’m writing this article. I’ve put an experimental reimplementation on GitHub of the library for you to try out, before it goes into the mainstream release. Originally in the “napi” branch, it’s been promoted to the master branch.

Update: This new version is now on npm as the ibmmq 2.0.0 release and has been merged into the main GitHub branch.

Another SHARE done

Last week was another MQ event with SHARE. This time in Atlanta. Though I managed to combine it with seeing a customer in Dallas the previous week. SHARE was a slightly abbreviated event compared to usual, because the venue had to be booked before it was clear that face-to-face meetings would recover. So we didn’t have quite as many MQ sessions as usual. In fact, all the MQ talks were done by myself, Lyn and Dorothy either as individuals or in various double-act combinations. But it was a really valuable week, with lots of useful discussions. And the brewpub near the hotel was as good as I remembered from a previous trip.

The planning now starts for the next, fuller, event in New Orleans in August.

Just really annoying that I picked up a bug on the flight home …

Monitoring MQ availability

One of the focus areas for new development in MQ in recent years has been in the area of High Availability and Disaster Recovery. Technologies such as RDQM and Native HA, and automatically managed logfiles, give a range of possibilities for ensuring your messaging systems continue reliably. Alongside the core function, there are also metrics and status information to show more about what is going on. And so the latest updates to the open source monitor programs add collection of some of these recently-added values. This should simplify monitoring MQ availability.

More on Active Directory with MQ on Linux

Several years ago I wrote about using Active Directory (AD) with MQ-specific authentication and authorisation options on a Unix queue manager. In that scenario, AD serves as an LDAP server. The MQ CONNAUTH attribute points at an IDPWLDAP format of AuthInfo object.

There is another approach to using Active Directory with MQ on Linux, where the directory is much more integrated with the operating system. I have seen enough confusion between these two options that I thought it was worth writing something to explain. I’ve had several apparently independent streams of notes on this topic in the last month alone (not to mention the person who seems to have asked everyone they know in the hope of at least one of them giving the answer they want to hear even if it’s wrong).
