In MediationZone 9.3, there are the following known issues:

Installation and Upgrade 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 Is Not Possible if MZ_HOME Path Contains a Folder Name with Spaces

If the MZ_HOME path contains spaces the installation will fail. Please ensure the MZ_HOME does not contain any spaces before installing.

Installation is 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]"/>.

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.

Issues with HTTP Batch after Upgrading

When upgrading from MediationZone 8 to MediationZone 9, there are the following issues with the HTTP Batch agent:

• In MediationZone 8, the HTTP Batch agent has a non-standard way to configure keystore information where instead of referencing a file on disk, the full file content is kept in the configuration. Currently there is no way to configure this in the same way in MediationZone 9.

• If you configure a keystore in MediationZone 8, either in the profile or in the agent, the certificate handling will be completely disabled, and all server certificates are accepted. This is different compared to the REST client agent where the profile/keystore is used as both keystore and truststore.

User Interface issues

New Desktop Issues

Database Agent Assignment Tab Value Are Not Cleared

When Value Type is set to "To UDR" or "NULL", the Value column are not cleared.

When viewing the repair jobs in the new UI they are displayed in one line which is hard to read.

Accessibility Issues

The new web-native desktop aims to be fully accessible, but there are currently some outstanding issues regarding this. These include:

• In some interfaces, the keyboard navigation doesn't follow the ideal order or convention

• Incorrect behavior of radio buttons
  
  

Code Editor Issues

The code editor in the desktop provides code completion and syntax highlighting there are some known issues with syntax highlighting not being correct, it is not possible to add tabs to code and code completion cannot be activated on a Mac if multiple keyboard layouts are enabled.

When attempting to use the code completion function in agents or profiles, for example, the Analysis agent, the built-in keyboard shortcut of Command + Space on a Mac computer will not trigger the code completion dialog box. 

Known Differences Between Desktops

There are some known, minor issues with differences between the two Desktops.

Importing Old Data Veracity Collection Agent Workflow Configurations Returned Validation Errors

If you have an old Data Veracity Collection Agent Workflow configuration from version 8.x, it is possible that validation errors about invalid Analysis Agents may occur.

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.

Data Veracity Filters Are Not Refreshed Automatically

The Filter page is not always the latest, after creating a new Filter from the Data Veracity Search page, you may need to click the Refresh button to view it.

Data Veracity New Restricted Fields That Were Used For An Existing Repair Rule Is Not Disabled

If setting a new restricted field that was used in a previously created Repair Rule, it is expected that the rule on the said field should be grayed out when viewing the saved Repair Rule and be ignored when applying repair tasks.

This is not the case as the rule on the said field still appears to be editable in the old Saved Repair Rule.

Duplicate UDR issues

With the SQL Storage Duplicate UDR profile set to use System Arrival Time, UDRs with dates older than the system time on the Platform will not be handled properly. The Duplicate UDR Inspector will not display any data despite the UDRs being processed.

When using File Storage Duplicate UDR profile with System Arrival Time as well, you might see Records and Duplicates as 0 in the legacy desktop Duplicate UDR Inspector.

Duplicate UDR Inspector Table Header Row Count Is Not Updated When Records Found Is 0

When searching a profile that has no records after previously searching with a profile that has any records, the table header would still display previous row count.
