Two steps forward, no steps back with IBM MQ V9.0.4

October 24, 2017

hopscotch

Compromise is everywhere. We are told to take the rough with the smooth. The easy with the hard. The quick win and the hard slog. And with software we often have to accept compromises. Especially so these days with the drive for new function forcing some compromises with stable deployments.

Not so with the latest update to the MQ family of products. For the last 15 months IBM has been delivering updates to MQ using a Continuous Delivery stream. There have been many useful additions, but they have always required adoption of the latest version to take advantage of the new features. With the latest update moving to MQ V9.0.4, there are even more substantial updates of useful features for both base MQ and MQ Advanced. However in recognition of the need for customers to keep some systems back-level while also wanting to take advantage of new features, some of these updates are designed to allow existing deployed systems to take advantage of the new capabilities, both without being updated and without breaking the Continuous Delivery and Long Term Support principles.

In addition to this extremely useful update, which I will get to in a minute, which can be used across the entire MQ estate, there are some groundbreaking updates that will allow huge changes in the way MQ is used, deployed and managed in this update. It is more leaps forward rather than steps forward.

For MQ Advanced we have 3 key new capabilities:

  • A new ‘easy HA’ feature – Replicated Data Queue Managers
  • More flexible Managed File Transfer deployments
  • Availability of an enhanced Blockchain bridge

For MQ Base (which is part of MQ Advanced) there are a number of other enhancements

  • Additional commands supported as part of the REST API for admin
  • Availability of a ‘catch-all’ for MQSC commands as part of the REST API for admin
  • Ability to use a single MQ V9.0.4 Queue Manager as a single point gateway for REST API based admin of other MQ environments including older MQ versions such as MQ V9 LTS and MQ V8.
  • Ability to use MQ V9.0.4 as a proxy for IBM Cloud Product Insights reporting across older deployed versions of MQ
  • Availability of an enhanced MQ bridge for Salesforce
  • Initial availability of a new programmatic REST API for messaging applications

 

All of these features are called out in the new announcement letter for MQ V9.0.4 here. And there are further updates available for the MQ Appliance listed in the specific announcement letter for it here and in another blog entry here. There are also announcement letters for IBM MQ z/OS V9.0.4 and IBM MQ Advanced for z/OS VUE V9.0.4

However, let’s try and call out some details of the key points of the MQ V9.0.4 update below:

RDQM1

The new High Availability feature (officially described as Replicated Data Queue Managers or RDQM) provides a significant new way to configure High Availability. It is only available for MQ Advanced users on x86 Red Hat Linux. It is designed as a 3 node system which uses replication of messages and logs between the local disks available to each Queue Manager. This style of replication of local disks was previously only available with the MQ Appliance. As moving to this new style of HA will allow customers to stop using network storage for MQ, we anticipate it will be very popular. As well as the disk level replication, Floating IP will be used to help applications move seamlessly to a failover QM. And 3 nodes help to prevent ‘split-brain’ situations where 2 nodes are simultaneously active.

The licensing of the above deployment requires MQ Advanced as already stated. However as long as all Queue Managers on all 3 nodes are Replicated Data Queue Managers, and all 3 systems are the same capacity, then only one node needs to have a MQ Advanced license entitlement. The other 2 nodes can be licensed with MQ Advanced High Availability Replica parts (these parts used to be called Idle Standby parts).

RESTproxy

The changes to the REST API for admin are also significant. Over the last few releases more and more ‘verbs’ have been added to allow REST API calls to configure and manage MQ. This was designed to allow more modern tools to be built as an alternative to MQSC and PCF based tooling. The latest V9.0.4 release adds more verbs and also a way to call the remaining equivalent MQSC functions within a REST API structure. However what is perhaps more interesting is that a single V9.0.4 Queue Manager can now act as a ‘gateway’ Queue Manager to allow these new REST API driven tools to configure and manage Queue Managers that are older and don’t include this new Continuous Delivery function. This is hopefully a very good way of providing the best of both worlds. Allowing the older production Queue Managers to remain deployed but still take advantage of new features.

Similar to this ‘bridge’ feature is one for IBM Cloud Product Insights, where the ability to publish deployed Queue Manager data to Cloud Product Insights was limited to releases on the Continuous Delivery stream, but now a single V9.0.4 Queue Manager enables older installs to publish data to this useful dashboard tool.

The MQ bridge for Salesforce has been enhanced to allow MQ to publish data into Salesforce, instead of simply receiving push notifications from Salesforce.

Customers with MQ Advanced who want to explore the possibilities offered by Blockchains now can deploy a bridge which enables MQ applications to query the Blockchain, and also provide data input into it. An earlier version of this was available only to customers with MQ Advanced for z/OS VUE, but this version is available to customers using MQ Advanced on distributed platforms.

MQ Advanced customers also get more flexibility in how they can deploy the file logger in MQ Managed File Transfer scenarios, as this logger can now be deployed on a different machine to the MQ Queue Manager.

And finally, feedback from customers told us that developers were looking to make sure of MQ, but with fewer dependencies, to free them up from client and language bindings. As such we have also added the first layer of support for a new set of programmatic REST APIs for messaging applications. This will replace the previous HTTPBridge function which has already been deprecated. Over the next few releases it is hoped that more functions will be supported in this REST API for messaging to allow additional messaging calls to be supported.

Counting up the advances it does look like it is more than 2 steps forward, and certainly no steps back. And with the ability to use some of these features alongside your older MQ releases, what are you waiting for? Download it from here today. Or try it on Amazon AWS Quick Start.

Building higher – IBM MQ V9.0.2

March 16, 2017

When a building is being constructed, it can be hard, from moment to moment to see progress. Yes – you see lots of activity. Lots of people are busy doing all sorts of important jobs, but it can be hard to see what they are all doing. You need to find a way to keep track of how they are doing. What progress are they making, and what milestones are they hitting.

building construction

In delivering updates to IBM MQ, now that we are on a ‘Continuous Delivery’ schedule, we set these milestones of deliveries around 3 times a year. We don’t plan to do IBM announcement letters with every update, but will do blogs here and elsewhere for some of the updates, with official announcements for others. For IBM MQ V9.0.1, there was an announcement letter, and I blogged about it here, but with IBM MQ V9.0.2 there are only blogs – both this one and our development blog from Ian Harwood you can find on developerWorks here. Also there is a YouTube video talking about the new update.

So, what has the development team has been working on in MQ V9.0.2? As with the 9.0.1 update there are several areas of enhancement and new function including:

  • Additional REST API coverage
  • Further updates to the MQ Console
  • Improvements in MQ MFT specifically in MFT Agent status reporting
  • Simplification in managed MQ logging on distributed platforms
  • MQ Appliance support for HA key renewal and 9.0.2 REST API verbs
  • Support for IBM Cloud Product Insights for registration and usage
  • Integration with Salesforce messaging events
  • Native Debian installer support for Ubuntu
  • Availability of MQ Advanced for Developers in the IBM Bluemix Container Service

 

Perhaps as with our description about building construction above, the delivery of any of these features might not be significant, although I think that the logging improvements will make a substantial difference to the many aspects of the use of MQ in the thousands of customers using it today.

 

What hopefully does become apparent is our ongoing support for the continuous delivery process. While some of these updates are brand new and have taken a lot of work, others are continuing to build on the work done in the MQ V9 and MQ V9.0.1 deliveries. These incremental deliveries of REST API support, and now the new Cloud Product Insight support will continue in future Continuous Delivery releases, making these features and the product more useful.

 

Let’s look at a handful of these new features starting with the logging support. Logging is very much the heart of IBM MQ and it is these recovery logs which allow MQ to recover from a failure, therefore providing the reliable and robust nature of IBM MQ. While circular logs are easier to manage, many customer use linear logs but these come with a lot of administrative overhead. The new feature allows for automatic management, recording and reuse of logs, lowering both the administrative overheads and improving the overall throughput in the system

 

IBM Cloud Product Insights is a new cloud hosted offering that many different IBM products will be able to work with. Additional features will be added to work with this over time, but initially there is support for registration and usage. You will be able to register your instances of IBM MQ and track them on the Product Insights dashboard. At this time you will be able to see what level of IBM MQ is install, where, and when it was last running. You will also see some usage information such as the number of persistent and non-persistent messages put, and the total size of data being moved through MQ. There is also a beta of log management, where MQ error logs will be shared with the Product Insights dashboard.

MQSalesforce

You may have seen the recent announcement of IBM and Salesforce working together more closely. We are very pleased that one of the ways this relationship is being demonstrated is through a bridge between Salesforce and MQ. When an event happens in Salesforce such as a change to data or a new application being run (Salesforce Platform Events or PushTopics), there is now the ability to trigger a MQ message to provide information about that event without the MQ application needing to be directly connected to Salesforce, simplifying your environment but making your systems more connected.

 

And finally, we now have a version of MQ Advanced for Developers available in the Bluemix Container Service. This means that the fastest way to create a development environment for IBM MQ might be with a couple of clicks to provision MQ Advanced for Developers. With pre-configured defaults to simplify administration, there has never been an easier way to get started with IBM MQ. What are you waiting for?
