We’ve just released V3.0.18 of z/OS Connect EE.

There have been some enhancements that you may be interested in, plus several APAR fixes.

More information about security in the IBM Knowledge Center

The Security section of the z/OS Connect EE IBM Knowledge Center has been significantly enhanced to provide more information about the supported security methods when z/OS Connect EE is used as an API provider. The new content provides more conceptual information to help you choose the most suitable configuration for your installation.

For each of the security principles (authentication, identification, authorization, integrity, confidentiality, and auditing) described in the Security Overview, there is a learning path which informs the reader how the security principle relates to z/OS Connect EE. This is followed by one or more tasks giving step by step instructions on how to configure the security principle with z/OS Connect EE.

New interceptor messages

Messages are now written to the messages.log file when interceptors, that are defined globally or for specific APIs or services, are activated and deactivated, to enable verification of interceptor configuration.
Example extract from z/OS Connect EE messages.log file:

Upgrading from a previous release of z/OS Connect EE

If you are upgrading from a release earlier than z/OS Connect EE V3.0.16, the first time you start up your server, you must specify the
--clean option on your started task PARMS statement, for example: /S BAQSTRT,PARMS=' serverName --clean'. This is to delete all persistent cached information and pick up updated OSGi bundles shipped in V3.0.16.
Find out more about the --clean option.

If you fail to specify the --clean option your server may not function correctly and you may see the following errors in your messages.log, STDERR, and FFDC:

com.ibm.ws.kernel.feature.internal.Provisioner E CWWKF0002E: A bundle could not be found for org.apache.commons.compress/1.9.0.
com.ibm.ws.logging.internal.impl.IncidentImpl I FFDC1015I: An FFDC Incident has been created: “java.lang.IllegalArgumentException: Missing bundles: [org.apache.commons.compress/1.9.0@file:{your_install_path}/usr/lpp/IBM/zosconnect/v3r0/runtime/lib/commons-compress-1.9.jar] com.ibm.ws.kernel.feature.internal.FeatureManager checkInstallStatus”at ffdc_18.12.14_10.42.56.0.log

Subsequent starts of the server do not require the --clean option.

API toolkit and Runtime compatibility

If you plan on upgrading the API toolkit to V3.0.6 (or later), ensure that you also upgrade the z/OS Connect EE server runtime to V3.0.16 (or later). If you do not upgrade the z/OS Connect EE server runtime, you may encounter an internal server error when deploying an API that has operations without a response mapping.

WebSphere Liberty Profile

The version of WebSphere Liberty Profile that is embedded in z/OS Connect EE V3.0.18 is V18.0.0.4. 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.

Angel V10

The version of the angel shipped with WebSphere Liberty Profile V18.0.0.4 is version 10.

To check the version of the angel you can issue an MVS system MODIFY command:

modify <angel jobname>,version

For example,

modify baqzangl,version

If using the Angel shipped with WebSphere Liberty Profile V18.0.0.4 the output should appear as:

WOLA and CICS TS 5.5

WOLA is supported with CICS TS 5.5. However, when you start up the TRUE, a message similar to the following will be written to the BBOOUT log file of your CICS region:

TC47BBOC 20190103172340 ue is 0.0000059 WOLA TRACE 0: The current CICS level 0505 is not supported

This message, issued by WebSphere Liberty Profile V18.0.0.4, can be ignored.
