Following the recent announcement of IBM MQ version 9.3, I am pleased to say that the IBM MQ for z/OS 9.3 performance report is also now available.

The report shows that when migrating to 9.3, the performance of existing workloads will remain comparable.

In addition the report details the performance of the new features and I will briefly highlight some of those features below:

• SMF enhancements which allow the capture of statistics and accounting data on separate intervals. Statistics data is cheap to capture and is small in volume, whereas accounting data is more expensive and can be large in volume. With MQ for z/OS 9.3 there is the ability to define separate intervals, allowing more frequent capture of statistics data without having to capture large volumes of accounting data.
• The addition of queue statistics to provide relevant data for each queue withou the burden of collecting accounting information or having to write an application to issue the DISPLAY QSTATUS command.
• The implementation of streaming queues which allows the configuration of a queue to put a near-identical copy of every message to a second queue.  Streaming queues can be useful in certain scenarios, where a copy of the message is required. For example:
  
  • Performing analysis on the data going through the system.
  • Storing messages for recovery at a later time.
  • Capturing a set of messages to use in development and test systems.
  • Consuming IBM MQ event messages from the system event queues, and sending additional copies to other queues or topics.

Finally, the latest update of MP16 – the capacity planning and tuning guide for MQ for z/OS is available and includes the performance impact of upgrading our DASD on MQ for z/OS' log rate capability.
