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 The SupportPac will move to “withdrawn” status – still downloadable, but not as prominent.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.

Options for MQ identities

I’ve written in earlier posts about confusion between different ways of using LDAP with MQ for authentication. Despite those articles, I still see questions from people who don’t really know what they can or should do.

As an attempt at simplifying the possibilities for a Linux environment, I drew up this chart. It is based on where your identities are defined.

Node.js Add-ons: Object transformation performance

While working on the redesigned Node.js C++ add-on for MQ, I had a question about transforming objects. What was the best method for Node.js performance? Noone answered the question on the internal channels I tried. I also couldn’t find anything definitive on external documentation or blogs. So I wrote my own tests …
