Category: Message Broker

Message Broker software for system integration. This includes the following history of IBM Message Brokers: MQSeries Integrator (MQSI), WebSphere Business Integration Message Broker (WBI-MB), WebSphere Message Broker (WMB), IBM Integration Bus, (IIB), and Application Connect Enterprise (ACE). While primary emphasis is placed upon the IBM software stack, other offerings such as MuleSoft are also included in this category.

MQ – Performance Tuning

MQ Technical Conference.  September 2015.  Powerpoint presentation.
“IBM MQ – Performance Tuning“  (44 slides).

View the Presentation

This presentation first provides a high-level overview of asynchronous messaging concepts.  The presentation then dives into the internal details of how MQ processes messages: from the “putting” of the message, through logging, file I/O, channel transmission, and finally to the “getting” of the message.  A seventeen step model of this process is presented.

The process of identifying the MQ bottlenecks during MQ processing, as well as some options for addressing those bottlenecks, are presented.  The difficulty of obtaining accurate measurement data is discussed, as is the need to benchmark the MQ infrastructure separately from the Application.  The two sets of data are both essential to any performance discussion.  Finally, some of the available and relevant tools are discussed.

By the end of the presentation, the viewer should have a basic understanding of the internal MQ processes that control performance, some of the Application design patterns to address performance, a conceptual model and strategy for measuring performance, and some initial tools with which to perform the analysis.

IBM Integration Bus – BAR File Management

TechDoc.  IBM Integration Bus.  BAR File Management.
February 2015. 23 pages.
Download TechDoc

This TechDoc describes the creation, deployment, and management of Broker Archive (BAR) files.  The complete life-cycle of a BAR file is described and, in the absence of Source Code Management (SCM) software, a deployment and management process is proposed.  All of the commands necessary to manage BAR files are covered in detail.  These commands are:

  • mqsicreatebar    (Create a BAR file)
  • mqsiapplybaroverride    (Modify the properties of a BAR file)
  • mqsideploy    (Deploy are BAR file to an Integration Server)
  • mqsireadbar    (Display the properties of a BAR file)

This document should provide all of the information necessary to understand, build, deploy and manage Broker Archive (BAR) files.  In addition, enough command detail is provided to allow an IIB administrator to be able to automate this process through scripting.
