The MQ 9.3.2 announcement letter also contains an overview of the release content.

  • Migrating from Docker Hub to the IBM Cloud Container Registry
    Pre-built IBM MQ Advanced for Developers and IBM MQ Operator container images have been available on Docker Hub for many years.  IBM now has its own secure container registry, so is migrating its free-to-use container images from Docker Hub to the IBM Cloud Container Registry ( The IBM registry does not apply the same rate limiting that Docker Hub has introduced.  Use of Docker Hub was deprecated from February 2022.
    For further information on this and configuration updates needed to find the images on the IBM Cloud Container Registry, see this article

  • IBM MQ Appliance Disaster Recovery configuration between HA pairs
    A requested feature  for the MQ Appliance has been to have a High Availability pair of appliances in one location serve as the DR failover for a HA pair of appliances in another location and vice versa. The MQ Appliance 9.3.2 firmware delivers this capability, including the updates to the Web console to configure the systems. For a more in depth look and links to further information see Jamie Squibb's blog article.

  • TLS 1.3 support in the MQ .NET Clients
    MQ 9.3.2 brings the .NET client up to parity with other parts of the MQ product by adding TLS 1.3 support. The MQ .NET and XMS .NET clients are available from or IBM download sites. See the Downloadable resources section for the links.
  • Initial support for Java modules
    MQ Classes for JMS and MQ Classes for Jakarta Messaging ( now includes support for Java modules.
    • To use the MQ Classes for JMS configure the application to require and add the “java/lib/modules/javax” subdirectory of the MQ installation directory in their module-path.
    • To use the MQ Classes for Jakarta Messaging configure the application to require and add the “java/lib/modules/jakarta” subdirectory of the MQ installation directory in their module-path.
    • Display QMStatus enhancements in runmqsc and PCF
      The MQCMD_INQUIRE_Q_MGR_STATUS PCF and DISPLAY QMSTATUS commands have been updated to provide additional data on the queue manager, include data and log file file system sizes and percentage used, clustering and Native HA instances.

    • New web Console application view
      The MQ web console adds a new view of the applications that are connected to a queue manager, with an overview and the ability to drill down for more details.

    • Ability to set the user context user for the messaging REST API
      From IBM MQ 9.3.2, it is possible to configure what user context is used for authorization when using the messaging REST API. Either the user that is logged into the messaging REST API or the user under which the mqweb server is running can be used. This can help simplify security configuration because only the user that starts the mqweb server needs authorization to access the IBM MQ objects.

    • IBM MQ Classes for JMS /Jakarta Messaging connection strategy
      A new property can be used to set the connection strategy for sharing TCP/IP connections between JMS Objects. GLOBAL minimises the number of open sockets, whilst CONNECTION minimises the connection time.

    • MQ IPT trace file configuration options
      The number of trace files and size of files used by MQ IPT can be configured using the TraceFileSize and TraceFileCount properties in the MQIPT configuration file

    • IBM MQ for z/OS SMF accounting data enhancements
      The number of messages being streamed using the Streaming Queues feature added in MQ 9.3 can be tracked using the new StreamedN datapoint in the CSQDWQ macro.

    Remind me how the Continuous Delivery support model works…

    It's worth reminding you what the Continuous Delivery support model means for MQ.

    • MQ 9.3 LTS is supported for a minimum of 5 years from its availability in June 2022, and will receive fix only updates through fixpacks versioned, and so on.
    • MQ CD updates will be delivered with the 3rd digit change – 9.3.1, 9.3.2 and so on. Defect support for a CD release is available for 12 months from the availability of the release or while it remains one of the two most recent CD releases, whichever is longer, so you need to keep moving forward with the MQ CD releases.
    • MQ CD updates will be delivered with new function enabled by default.
    • The IBM MQ FAQ for Long Term Support and Continuous Delivery Releases will hopefully answer most of your questions.
