In MediationZone 9.0, there are the following known issues:

See Fixed Known Issues for information about known issues that have been fixed since the release of 9.0.0.0.

Installation issues

Unable to change platform database after installation

It is not possible to change platform database after the installation is completed which used to be a feature that available since 8.x. This issue will be fixed in future releases.

Installation isn't possible if MZ_HOME path contains a folder name with spaces

If the MZ_HOME path contains and spaces the installation will fail. Please ensure the MZ_HOME doesn't contain any spaces prior to installing.

Installation reported as successful even if the platform fails to start

In some circumstances during installation the installer may report as successful when the platform has not started.

Warning messages displayed during installation

When the user performs “setup.sh prepare”, a warning message “setSecurityManager will be removed in a future release" is displayed. This does not impact functionality of MZ 9 installation and will be handled in future versions of MZ.

Error Occurs When Performing Multiple Installations on a Host with Different UNIX User IDs

The /tmp/syslog/syslog-debug.log file is created when a host machine contains an MZ 9 installation. This file will be overwritten by any subsequent MZ 9 installations that are performed on the same host machine with a different UNIX user ID. However, the attempt to overwrite this file will fail and cause errors to the subsequent installations.

To solve this issue, modify the platform.xml file setting by using the mzsh topo open platform command. Edit the platform.xml file, and change the directory to use another directory using the following command: <property name="mz.syslog.debuglogfile.filedir" value="[the directory]"/>.

Latest Oracle JDBC Driver Versions not Supported

Latest Oracle JDBC drivers such as version 21c and 23c are not supported in this release. Ensure to check the System Requirements for information about supported Oracle version.

Upgrade issues

Legacy Desktop launcher does not launch desktop when install.security is changed during upgrade

When the user with an existing installation has install.security set to false when installation was performed. When upgrading to version 9.x, the upgrade will set the install.security to true by default. This will result in an issue where one the upgrade is complete, the Legacy Desktop launcher will not launch the desktop and will instead have an error message say that it failed to retrieve binary data. If your existing installation was installed with install.security set to false, ensure that the install.security is set to false in the install.xml before performing the upgrade.

Unable to Upgrade When Using a Symbolic Link as MZ_HOME

Users are encountering issues with symlinks when using them as MZ_HOME during an installation or upgrade due to the java.nio.file.FileAlreadyExistsException error.

This issue arises from a bug reported under [JDK-8294193] Files.createDirectories throws FileAlreadyExistsException for a symbolic link whose target is an existing directory - Java Bug System (openjdk.org) and has been fixed in JDK 20.

To avoid encountering this error during installation or upgrade, you should use an absolute path instead of a symlink for the MZ_HOME directory.

Removing Unused Service Contexts After Upgrading from MediationZone 8

When upgrading from MediationZone 8 to MediationZone 9, all picos are upgraded resulting in an installation with numerous unused service contexts that should be removed.

To resolve this, you are required to use the mzsh topo command to manually remove these picos. For more information on the steps, refer to Removing Pico Configurations.

Example error during import:

Example error when viewing the invalid workflow Analysis Agent configuration:

To resolve this, you will need to re-add the Data Veracity UDR for Analysis Agent input UDR Types or use the Set To

Input button if applicable. After adding the appropriate Analysis UDR Types, save the workflow configuration.

ClassCastException after re-import WF configuration table

Missing <Agent> - 5G <Field> Parameters in Workflow Table and Workflow Instance Table

The HTTP2_Server_1 - 5G - 5G Profile, HTTP2_Server_1 - 5G - Primary NRF Address, and HTTP2_Server_1 - 5G - Secondary NRF Addresses parameters in version 8.3.2.X are missing from the Workflow Table and workflow instance table when upgrading from version 8.3.2.1 onwards to MediationZone 9.

The '<agent> - 5G - <field>' parameters in version 8.3.2.X

This is because the three parameters are classified under a different sub-category, the '5G Support' as HTTP2_Server_1 - 5G Support - 5G Profile, HTTP2_Server_1 - 5G Support - NRF Address, and HTTP2_Server_1 - 5G Support - Secondary NRF Address. 

The '<agent> - 5G Support - <field>' parameters in MediationZone 9

If the existing workflow contains these parameters from the older version, users are required to configure them under the new '5G Support' sub-category.

Aggregation session profile locked when exiting Explore Session using ESC key in Aggregation Session Inspector

In Aggregation Session Inspector, existing or closing the Explore Session using the ESC key on the keyboard will cause the profile locked exception when attempting any further actions such as Deleting a row. It is advised to close the dialog using the Cancel or OK button instead. Workaround for this issue is to restart platform. A fix is expected to be available in 9.0.3.0 release.

Open API Incorrectly Validates Request Body

Users are encountering an issue with request body validation when using a schema file that includes discriminator and oneOf keywords in the same schema object. This issue arises due to a limitation in the library implementation.

There is an existing ticket logged on this issue, see https://bitbucket.org/atlassian/swagger-request-validator/issues/771/discriminator-is-not-working-with-oneof. To work around this issue, you can disable request validation for requests containing the schema object.

Data Hub Workflow Aborts With “NoClassDefFoundError”

Users might encounter a “NoClassDefFoundError” in Data Hub Forwarding agent in MediationZone 9.0.3. This is caused by an unintentional removal of a library depdendency. To resolve this, the change will be reverted in the subsequent service pack release of MediationZone 9.0.
