We’ve just released the latest z/OS Connect EE open beta. We have added enhancements to enable you to create MQ service projects within the API toolkit, and increased the MQ message size from 32KB to 100MB. As always, we welcome your feedback on any features of the open beta.

MQ service projects now available in the API toolkit

The open beta version of the z/OS Connect EE API toolkit has been enhanced to enable you to create MQ service projects. This new feature not only allows you to simply create SAR files using the API toolkit, but has added the following benefits:

  • MQ messages can be up to 100MB in length.
  • Advanced data transformation options are available through the API toolkit.
  • Generated SAR files can be directly deployed to your z/OS Connect EE server.

SAR files generated through the build toolkit are still supported but do not benefit from the above features.

The Quick Start Scenarios in the z/OS Connect EE knowledge center have been updated showing you how to create an MQ service project using the API toolkit. For example,

MQ message size increased from 32KB to 100MB

When using the MQ service provider within z/OS Connect EE you can now send and receive MQ messages up to 100MB in length for services that were created using the API toolkit. (Note that services created through the build toolkit are limited to a message size of 32KB).

Open beta code available for up to 120 days

This version of the open beta is available for up to 120 days. We hope this will allow time for you to evaluate the new features offered through our beta and to provide us feedback on what you do and don’t like with these features. Please use the z/OS Connect EE open beta forum to provide your feedback.

Open beta version of the API toolkit

The open beta version of the API toolkit to accompany the open beta z/OS Connect EE runtime is V3.9.7.00. This open beta version of the toolkit will currently only run on Windows. You are strongly recommended to use this version of the API toolkit with the open beta z/OS Connect EE runtime to enjoy the full suite of new features available in both the toolkit and runtime, and also to ensure you maintain compatibility. For example, to try out the creation of MQ services, you must use this open beta version of both the API toolkit and z/OS Connect EE runtime.

Open beta build and expiry dates

The build date for this version of the z/OS Connect EE open beta runtime is 20200130-1034 and appears on the BAQR0000I message.

This version of the z/OS Connect EE open beta is due to expire on 29 May 2020 and appears on the BAQR9999I message. However, do not panic! A newer version of the open beta with additional enhancements will be available to download before this version expires.

WebSphere Liberty Profile 19.0.0.12

The version of WebSphere Liberty Profile embedded in this open beta is version 19.0.0.12. The version level of the WebSphere Liberty Profile appears in both the top of the z/OS Connect EE messages.log file, and also in the STDOUT logfile.

If you choose to remain at a lower version of the angel, you will see the following warning message in your z/OS Connect EE messages.log file when you start up your server:

Java 8 required to run z/OS Connect EE

Java 8 is the only supported level of Java with this version of the open beta. Your z/OS Connect EE server will not start if Java 8 is not used. It will fail with message “CWWKE0042E: The correct Java version is not running. The runtime environment requires Java 8 or higher”.
