Known Issues

In MediationZone 9.1, 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 doesn't 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]"/>.

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 database version.

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.

Platform Instances and Runtime Data Need to be Removed Post Upgrade

Due to some issues with the Desktop cache, platform instances and runtime data must be cleared from the Desktop Launcher, see Removing Instances and Runtime Data.

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.

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 is not cleared.

Database Agent MIM Browser Need To Click Twice To Close It

The MIM browser open from database agent, need to close it by hitting twice on cancel button or the X button to close it.

External Reference Profile Datalist Can Be Altered in Read-Only Mode

When certain procedures are made, it is possible to alter the data list found in the external reference profile while the read-only mode is used. This causes a system-wide DRRCPException to be thrown.

Login Web UI Will Go To Last Page That Last User Accessed 

User A log out from web UI, and User B login, it will automatically go to the page last accessed by User A.

Integer Field Validation Can Be Broken

Inputing integer values outside of the expected range can break the validation in the UI.

Type Assigned Indication not Shown in MIM Browser

This can be viewed in the Legacy Desktop if required.

Idle Timeout Only Warns the User Once

Inactive users will be logged out after a configurable period, following a warning to that effect. If a user is active after the warning they won't be logged out, but if they are inactive again then they will be logged out with no warning. 

Cannot Login to Multiple Platforms

It is not currently possible to login to multiple separate platforms using the new UI in one browser. Users can use different browsers, incognito modes, or the Legacy Desktop if this is required.

Data Veracity Repair Jobs Show in One Line

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 new web-native 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.

Legacy Desktop Issues

In the Legacy Desktop an exception may occur when you first log in to the Platform. If you log in again the exception is not shown.

Data Veracity issues

Data Veracity Search Filtering For Some Fields Are Case-Sensitive

The filtering for the source_node and message fields in the Data Veracity Search & Repair table are case-sensitive.

Data Veracity Filter's Full Query Is Not Available In Web Native UI

The full filter query for Data Veracity is not available for viewing in the web UI. A partial display of the query can be seen in the filter listing under Data Veracity > Filter listing.

Adding an Empty Query Group With a Parent Condition in Data Veracity Search & Repair Filter Will Result In An Error

Attempting to add an empty query group with a parent condition will cause an error to be thrown upon clicking OK. A sample of the query setup is shown below.

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.

Example error during import:

The following agents returned validation errors.
Analys

is_1 is invalid.
The UDR type DataVeracityUDR (DataVeracity) doesn't exist

Example error when viewing the invalid workflow Analysis Agent configuration:

Error: Failed to set UDR Types
 
Message: Unable to create UDR type description from DataVeracityUDR (DataVeracity).

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 Filter Are Not Refresh 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 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 gray out when viewing the saved Repair Rule and be ignored when applying repair tasks. However, the rule on the said field still appears to be editable in the old Saved Repair Rule.

Other issues

Logging Issue

When logging out of the legacy desktop desktop_current.log has unnecessary logs added

Error Thrown When SAPCC Agent Not Added With Any Host

In the SAP CC Batch agent, do not add any host, click the Save As button, and you will find the error shown below: 

java.lang.NullPointerException: Cannot invoke "String.matches(String)" because "hosts" is null

Inappropriate Validation Handling On Workflow Group Scheduling

In Workflow Group Scheduling, when adding a duplicate execution day plan, it prompts the wrong validation message content and if the user continues to save, scheduling data will be wiped off.

Database Forwarding Agent Validation Message

In Database Forwarding Agent, when we have a field NULL/To UDR, the validation message that prompted does not properly describe the problem.

mzsh topo show pico-view Does Not Dispaly Full Information

The mzsh topo show pico-view does not show the pico names in the output. Picos can be viewed in the Desktops

External References Can Be Removed when a Workflow is Dependent on It

External references of the type Database Properties can be removed even if they are in use. Any workflows using these references will become invalid.

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.

The Aggregation Inspector Does not Work with Aggregation Profiles Using External References

If you have an Aggregation profile using External References, the session data will not be visible in Aggregation Inspector. To solve this, you can update the Aggregation profile to not use External References once the session data has been made available, the data will then be visible in Aggregation Inspector.

File Storage Aggregation Data not Removed when Modifying Profile

If you have an Aggregation profile with File storage selected and select to change the Storage Host or the Directory, or change to a different storage type, you will have to manually remove data. However, if this is done in the Legacy Desktop, data will automatically be removed.

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 MediationZone9.1.1. This is caused by an unintentional removal of a library dependency. To resolve this, the change will be reverted in the subsequent service pack release of MediationZone 9.1.
