When connecting to a MySQL database via JDBC, there will occur below connection error message from TAC or Talend tMysqlConnection, tMysqlInput and tMysqlOutput components.
java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowed
The error message java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowed
typically occurs when you're trying to connect to a MySQL database using JDBC and the connection URL is not correctly configured to allow public key retrieval for SSL connections. This is a regular setting when using MySQL 8.0+ with certain security configurations.
Add client option to your connection URL mysql-connector allowPublicKeyRetrieval=true to allow the client to automatically request the public key from the server.
jdbc:mysql://localhost:3306/db?allowPublicKeyRetrieval=true&useSSL=false
Accessing the Qlik Sense Enterprise on Windows Hub or Management Console fails with the following error:
Your connection isn’t private
Attackers might be trying to steal your information.
NET:ERR_CERT_REVOKED
The currently installed 3rd party certificate has been revoked. To resolve the issue, we will locate the certificate currently used and delete it from the Windows certificate store. This will prompt Qlik Sense Enterprise on Windows to revert back to its self-signed certificate and allow access to the Hub and Management Console.
The currently installed 3rd party certificate has been revoked.

How to retrieve users and user attributes from excel in Qlik Sense?
The setting and process for Qlik Sense to retrieve user information from excel are almost same as the following 'ODBC example'.
It is very important to review the below information to set up the data source files and Qlik Sense configuration correctly. The real example provided will give a better understanding how exactly it works.
Each data source has a different configuration and the following example (Excel) of adding an ODBC user directory connector.
For .csv and SQL examples, please see the help site: https://help.qlik.com/en-US/sense/Subsystems/ManagementConsole/Content/ODBC-example.htm
Do the following:
Verify that the Microsoft Excel Driver is installed.
Set up an ODBC source on the server.
You need to store the data in two separate sheets in the same excel file, for example, for example you can place it in this location: %ProgramData%\Qlik\Sense\temp.
The temp folder is not included in the default installation. You need to create the temp folder, if not already done by another QMC administrator.
SheetA contains the users and SheetB the user attributes.
Example:
SheetA
userid | name |
1 |
John |
2 |
Bill |
3 |
Tom |
SheetB
userid | type | value |
1 | jd@email.com | |
1 | lastname | Doe |
2 | bg@email.com | |
2 | lastname | Gates |
3 | th@email.com | |
3 | lastname | Hanks |
Select User directory connectors on the QMC start page or from the Start drop-down menu to display the overview. Create a new user directory connector (ODBC) and edit the properties.
Identification
All fields are mandatory and must not be empty.
Property DescriptionName | The name of the UDC configuration, defined from the QMC. |
Type |
The UDC type. |
User sync settings
Property Description Default valueSync user data for existing users |
|
Selected |
Connection
Property Description Default valueUser directory name |
The name of the user directory. Must be unique, otherwise the connector will not be configured. The name must not contain spaces. |
- |
Users table name | The name of the table containing the users. Include the file extension in the table name, for example: [SheetA$]. | - |
Attributes table name | The name of the table containing the user attributes. Include the file extension in the table name, for example: [SheetB$]. | - |
Visible connection string |
The visible part of the connection string that is used to connect to the data source. |
- |
Encrypted connection string |
The encrypted part of the connection string that is used to connect to the data source. Typically, this string contains user name and password. The two connection strings are concatenated into a single connection string when making the connection to the database. |
- |
Synchronization timeout (seconds) | The timeout for reading data from the data source. | 240 |
Example:
User table name: [SheetA$]
Attributes table name: [SheetB$]
Visible connections string: Driver={Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)};Dbq=%ProgramData%\Qlik\Sense\temp
Click Apply to apply your changes.
Go to the User directory connectors overview and check if the user directory is displayed as Configured and Operational.
If the User directory name is not unique the connector will not be configured. If not operational, check the repository system log in: %ProgramData%\Qlik\Sense\Log\Repository\Trace.You have added an ODBC data source and initial synchronization will be performed within five minutes (by default).
R4Z Db2 mainframe install is completed but no Changes are coming through.
Check that the Tables you wish to be performing CDC replication upon, have been "turned on" for capturing the changes from the DB2 z/OS Logs.
Do this by using the following command. This can be performed by the DB2 Database Administrator.
Option 1: Make sure the Table has been altered for CDC:
ALTER TABLE schema.table DATA CAPTURE CHANGES
Option 2: If the UserId has the permissions it can be configured on the Db2z Endpoint in the Advanced tab.
Change Data Capture to: Automatically enable Data Capture Changes (requires admin privileges)
Varbinary Datatypes on Postgres Target databases are treated as LOB datatypes. Temporarily CSV Files generated by Replicate currently include LOB datatypes even when LOB support is turned off for the task. This leads to data being inputted into the wrong columns if there are LOB datatypes in your tables and LOB support is turned off.
Sample error of a numeric datatype column flowing into a Datetime column:
[TARGET_LOAD ]E: Command failed to load data with exit error code 3, Command output: psql:M:/Replicate/data/tasks/x3_testr4x_rez_ods_ls_pqsl_AgentTest_ac/data_files/1/LOAD00000001.csv.sql:1: ERROR: date/time field value out of range: "0"
The temporary CSV files of Replicate do not remove the LOB columns when LOB support is turned off. This leads to incorrect column matches.

A common request received is a method of grouping Qlik Sense apps into a folder. Eg: If there are many documents that address different categories (such as economics, politics, entertainment, charity etc) in the Hub, it may be good to be able to create folders within 'My work' in Hub to organize my documents and have them in the right folder.
See Folders in your own workspace and streams for details on the feature request and vote to provide us with more feedback!
The request is partially implemented using application tagging. See Fig 1.
A Qlik Replicate task using a SAP ODP Endpoint to replicate a table fails with the error:
[SOURCE_CAPTURE ]E: Text '%% TO BE DEFINED %%' could not be parsed at index 0 [1024719] (custom_endpoint_capture.c:800)
Modify the custom extractor and verify that the table or object is Delta enabled in SAP.
The Extractor or Object defined in the Qlik task is custom and not Delta enabled.

The initial recommendation is to repair the installation. See How to repair an installation.
If the repair does not resolve the problem:
The Qlik.Sense.Logging.dll present in [Installation Qlik Sense folder]\Repository\ was missing required inforamtion.
Qlik Replicate tasks using Oracle as a Source Endpoint fail after installing the Oracle July 2024 patch.
All Qlik Replicate versions older than the 2024.5 SP03 release are affected.
Upgrade to Qlik Replicate 2024.5 SP03 or later.
The Oracle July 2024 patch introduced a change to redo events. Qlik has since provided a fix for Qlik Replicate which parses the redo log correctly.
RECOB-8698
Making changes to a Qlikview document (.qvw) or Qlik Sense app (.qvf) will sometimes break already existing bookmarks. This is sometimes unavoidable and is a risk developers need to be mindful of when making changes to existing deployments.
Bookmark functionality can be affected by the following changes:
Making any of these changes can lead to bookmarks that only apply some of the intended selections, or even none at all.
A developer making changes to a document will need to keep these limitations in mind, and test any existing bookmarks, especially after using sensitive functions like "Always One Selected". If a bookmark is discovered to be broken, recreating it after the changes have been made is the best method to get back to a working state.
We in Qlik Support have virtually no scope when it comes to debugging or writing custom security rules for customers. That level of implementation advice needs to be handled by the folks in Professional Services or Presales. That being said, this example is provided for demonstration purposes to explain a specific scenario. No Support or maintenance is implied or provided. Further customization is expected to be necessary and it is the responsibility of the end administrator to test and implement an appropriate rule for their specific use case. For access to more tips and tricks, best practices, and ever-evolving creative solutions, we recommend joining us in our active Qlik Community.
In this scenario, the administrator wants to grant access to the Data Load Editor on a series of apps which the user or set of users already have read rights to.
When Qlik Replicate runs in CDC mode and CT tables are enabled, primary keys are replicated as null values in the CT tables.
Base tables are not affected by this.
The Oracle patch from the 19th of October 2023 changed the redo log format around how they log before images. Qlik has issued a patch (2023.5 SP5) to read the new format correctly.
A fix has been provided in Qlik Replicate 2023.5 SP5 and 2023.11 SP1.
Download and install one of the provided patches:
Qlik Replicate May, version 2023.5.0.516 and earlier.
Qlik Replicate 2023.11.0.159 (GA)
Scenario: Qlik Replicate is using a DB2 Z/OS Source Endpoint. During an IPL, tasks fail while connecting to the DB2 instance in the Data Sharing Group.

A DB2 configuration parameter (enableAcr) can be added to the db2dsdriver.cfg configuration file, which maintains the connection to DB2 during an IPL when the instance is in a Data Sharing Group.
For more information about enableAcr, see Element in the <acr> section of the db2dsdriver configuration file (Source: IBM.com).
Specifies whether automatic client reroute is in effect. The default is true. If the server accessed is Db2 for z/OS, the enableAcr parameter should be enabled only when the enableWLB parameter is in effect.
Qlik Data Gateway erroring out with "Invalid metadata response (DirectAccess-2201) " message. The error could be due to a different issues.
The cause of the issue is usually configuration, if the suggestions above didn't fix the issue it will be necessary to report the issue for further analysis.
