z/OS Connect EE V3.0.44 released

By Alan Hollingshead posted Mon April 19, 2021 09:54 AM

  

We have just released V3.0.44 of z/OS Connect EE.

In this release we have upgraded the version of Liberty to V21.0.0.3 which includes a fix to prevent HTTP response codes 404 occurring during the start up of a z/OS Connect EE server. We have also added a new topic in the Performance section of the IBM Documentation (formerly known as the Knowledge Center) to demonstrate how you can use z/OS Workload Management (WLM) to classify API requests and the Resource Management Facility (RMF) to measure z/OS Connect EE API workloads.

WebSphere Liberty Profile V21.0.0.3

The version of WebSphere Liberty Profile that is embedded in z/OS Connect EE V3.0.44 is V21.0.0.3.
This version of Liberty includes a fix that prevents HTTP return code 404 during server start up. Therefore you no longer need to pause your endpoint ports during the start up of your server to prevent HTTP return code 404.

Angel V16

The version of the angel shipped with WebSphere Liberty Profile V21.0.0.3 is version 16.
If you choose to update to the version of the Liberty Angel shipped with this PTF, the following error message will appear in the system output for the Angel:

CWWKB0086E THE NAME SPECIFIED FOR ELEMENT WAS NOT VALID WHEN TRYING TO REGISTER WITH ARM. THE PROGRAM ROUTINE EXITED WITH RETURN CODE: 8 AND REASON CODE: 2c.

This error message can be safely ignored. The angel process starts and functions as normal. 
If you choose not to update to this level of the Liberty Angel, then the following warning message will appear in your messages.log file:

CWWKB0127W: The current angel version is earlier than the version that the server expects. Update the angel version to the latest available version.

New topic in z/OS Connect EE Documentation to measure APIs

A new topic in the IBM Documentation shows how you can use z/OS Workload Management (WLM) to classify API requests and the Resource Management Facility (RMF) to measure z/OS Connect EE API workloads. This is particularly useful if you want to measure the CPU cost of an individual API or API requester, or a group of APIs or API requesters.

API toolkit versions

The latest version of the z/OS Connect EE API toolkit plug-in to design and create your services and APIs is V3.0.9.1 for Aqua 3.1 users, and V3.2.9.1 for Aqua 3.2 users. You should obtain the latest version of the API toolkit from the Aqua download site for your version of Aqua as it includes all the latest features and fixes.

If unzipping the API toolkit zip file on Windows, due to the long filenames of some of the file members, you should use a tool such as 7-Zip or the “jar -x” command. Do not use winzip, winrar, or the Windows own zip extraction tool, as warnings/errors will occur during the unzip and the API toolkit will be unusable.
