Route(OSGI-based) service design facing child Job bundle jar (child bundle was introduced by cTalendJob in Route design), encounters the error "Unable to resolve root : missing requirement" after being deployed to Runtime. However, Route runs smoothly in Studio debug run mode.

The Runtime logs provide insightful error messages as detailed below:

org.apache.felix.resolver.reason.ReasonException: Unable to resolve root: missing requirement [root] osgi.identity; osgi.identity=TestBasicRoute-feature; type=karaf.feature; version="[0.1.0,0.1.0]"; filter:="(&(osgi.identity=TestBasicRoute-feature)(type=karaf.feature)(version>=0.1.0)(version<=0.1.0))" [caused by: Unable to resolve TestBasicRoute-feature/0.1.0: missing requirement [TestBasicRoute-feature/0.1.0] osgi.identity; osgi.identity=org.example.route.TestBasic; type=osgi.bundle; version="[0.1.0,0.1.0]"; resolution:=mandatory [caused by: Unable to resolve org.example.route.TestBasic/0.1.0: missing requirement [org.example.route.TestBasic/0.1.0] osgi.wiring.package; filter:="(osgi.wiring.package=@BundleConfigImportPackage@)"]]

Caused by: org.apache.felix.resolver.reason.ReasonException: Unable to resolve org.example.route.TestBasic/0.1.0: missing requirement 

Cause

The child bundle JAR is lacking the 'lib' and 'osgi-info' folders. Additionally, the custom Maven files ('pom.xml', 'pom-parent.xml', 'pom-bundle.xml', and 'pom-feature.xml') are outdated, which contravenes the Studio's default dependency settings during the compilation and packaging processes.

Resolution

1. Open Project Settings in Talend Studio, then navigate to Build -> Maven -> Set custom scripts by folder -> Route Designs -> Routes -> Delete Maven files, remove the old Maven files: 'pom.xml', 'pom-parent.xml', 'pom-bundle.xml' and 'pom-feature.xml'.
2. Rebuild and republish the service design.

Updating an Excel Worksheet using Qlik Application Automation leads to Microsoft Excel reporting a 503 error.

Resolution

A 503 (Service not Available) error indicates the target system, in this case Microsoft Excel, cannot handle the calls due to high frequency. To overcome this, a retry mechanism would need to be implemented in your automation, adding robustness in front of those errors.

Attached to this article is a sample automation demonstrating how to handle these errors in the Excel block and implement retry logic when it fails.

Cause

Third-party bottleneck.

TAC tasks are hanging on "Running" status for a long time in Job Server, and it does not end. 

Analysis

This issue can be identified by long duration of task execution time and it can be seen from the large time gap between the job end time and the task end time.

Usually, the time gap between the job end time and the task end time are small if there are no problems occurring.

Resolution

Please check and try the following points.

1. Check that the Talend Administration Center application (or service) is up and running.
2. Check that the connection can be established to the Job Server.
3. Check that there are no differences in the version of the Talend Administration Center and the Job Server, since the Talend Administration Center and the Job Server affect one another. If the version is old on either side, it may cause problems.
4. In order to reconnect Talend Administration Center and the Job Server, restart Talend Administration Center to see if it fixes the problem.

Cause

It is most likely that there are network connection issues (because of network infrastructure, VPN, etc)between the Talend Administration Center and the execution server (Job Server).
One possible situation may be the following: After the task is run by the Job Server, the execution result should be sent to the Talend Administration Center normally. If there is a connectivity problem between the Talend Administration Center and the Job Server, then the execution result will not be sent to the Talend Administration Center, which causes this problem.

After upgrading to Qlik Sense Enterprise on Windows May 2023 (or later), the Qlik Sense Repository Service may cause CPU usage spikes on the central node. In addition, the central Engine node may show an increased average RAM consumption while a high volume of reloads is being executed. 

The Qlik Sense System_Repository log file will read:

"API call to Engine service was successful: The retrieved 'StaticByteSize' value for app 'App-GUID' is: 'Size in bytes' bytes." 

Default location of log: C:\ProgramData\Qlik\Sense\Log\Repository\Trace\[Server_Name]_System_Repository.txt

This activity is associated with the ability to see the Base memory size in the Qlik Sense Enterprise Management Console. See Show base memory size of apps in QMC.

Resolution

The feature to see Base memory size can be disabled. This may require an upgrade and will require downtime as configuration files need to be changed.

A feature request (SHEND-225) has been logged but there is no information if and when the feature will be implemented yet.

Unable to Execute Talend job query after Talend Remote Engine and JAVA version 17 upgrade in PROD.

The Same query was running fine before on Java 11 version but after Java upgrade to 17,  it is unable to run the particular query and same jobs are failing due to below error

The original query inside hive tDBInput component has no grammar issue.

Execution failed with code 1 and error Job stopped with errors or unable to run. Exception in component tDBInput_4 (Outbound_File_Creation_Type_1) org.talend.sdk.component.api.exception.ComponentException: (java.sql.SQLException) [Amazon][HiveJDBCDriver](500051) ERROR processing query/statement.

Resolution

Try the setting "UseNativeQuery=1" in JDBC connection URL property to enable the use of Native query option.

For example:
jdbc:hive2://localhost:10000/foundation;AuthMech=2;UseNativeQuery=1

This parameter specifies whether the driver transforms the queries emitted by applications. 

1: The driver does not transform the queries emitted by applications, so the native query is used. 

0: The driver transforms the queries emitted by applications and converts them into an equivalent form in HiveQL.

If the application is Hive-aware and already emits HiveQL, then enable this option to avoid the extra overhead of query transformation.

Cause

As HiveQL is using parameter "UseNativeQuery=0" by default, which means it will transform query inside JDBC before sending to HS2 , and the introduced false optimization query will cause the problem. 

Environment

Qlik Replicate tasks using DB2 LUW Source Endpoint experience latency when consuming data.

Resolution

Verify if the DB2 LUW configuration for the DB2 instance of the Source endpoint has its configuration parameters LOGMETHOD1 and LOGMETHOD2 set to a backup device location.

This would indicate the DB2 Log Reader Agent is loading the transaction logs from a backup device which will add overhead to the task using this DB2 Source Endpoint.

To correct the condition you can set the DB2 parameter by the DBA Overflow Log path from NULL to archive_log_path. See overflowlogpath - Overflow log path configuration parameter for more information.

This path can point to a local disk on the DB2 server for optimal access to the DB2 transaction logs.

First log archive method:

(LOGARCHMETH1) = VENDOR:/opt/simpana/Base64/libDb2Sbt.so

Second log archive method:

(LOGARCHMETH2) = DISK:/db2/P10/alternate_logpath/

Overflow log path:

(OVERFLOWLOGPATH) = archive_log_path

Cause

This is the result of the DB2 Log Reader Agent, which Qlik Replicate calls using the DB2 API and from which we access the transaction logs from DB2. In a setup in which LOGMETHOD1 is pointing to a backup device, the DB2 Log Reader Agent loading the transaction logs will lead to overhead and ultimately latency.

When Qlik Data Gateway Direct Access is implemented, sometimes as the workload increases post-implementation, customers may experience general stability issues. We suggest a basic health check to address the more well-known problems and stabilize your gateway implementation. 

This article outlines three 

1. Verify the number of disconnects
2. Verify the number of ODBC connector crashes
3. Verify long-running metadata requests

Resolution

(1) Verify the number of disconnects

A high number of disconnects can cause reload disruptions. Some important disconnects will be recorded in the DirectAccessAgent logs. While a low volume of disconnects is expected and will typically recover within a few seconds, a high number of entries in the logs are indicative of a problem.

We suggest initiating an internal investigation if more than ten disconnects are found per day. 

Search for “[ERROR] Connection to”, sample:

[Service ] [ERROR] Connection to <mytenant>.us.qlikcloud.com:443 failed

If the amount of disconnections is high, we suggest to refer to articles: 

• Qlik Data Gateway - Direct Access. Reloads failing intermittently
• Data Gateway Direct Access disconnections (0x80004005): The remote party closed the WebSocket connection without completing the close handshake. 

(2) Verify the number of ODBC connector crashes

ODBC connector crashes can impact concurrent reloads if Process Isolation is not enabled. We suggest customers who experience crashes in their logs enable Process Isolation and configure Dump file creation. 

Process isolation for ODBC connector can be confirmed in the C:\ProgramData\Qlik\Gateway\configuration.properties. ODBC_PROCESS_ISOLATION_MODE, will be set to None if disabled, and set to Load if enabled.

It can also be verified using the logs. The ODBC logs named odbc-connector_logs.txt, odbc-connector_logs.txt.1 from 1 to n. If isolation is enabled, the files includes a port number, for example odbc-connector_logs_49156.txt where 49156 would represent a port number.

To identify whether there are crashes or not in your DAG (Direct Access Gateway) and proceed to enable Process Isolation we suggest reviewing Qlik Data Gateway - Direct Access - ODBC Crashes.

(3) Verify long-running metadata requests 

Other cause of issues would be due to misconfiguration of third-party drivers, the details are outlined in Qlik Data Gateway Direct Access Data Preview long metadata requests.

Keep in mind that these recommendations are additional validations to the Best Practices and System Prerequisites documented in our Help Site:

Advanced options is not visible when editing a sheet. This can happen on a specific app even if the option was present before.

Resolution

You can activate the "Show Sheet Header" option in the app settings to make the "Advanced option" button visible again.

1. Open the App settings.
   
2. Activate "Show Sheet Header".
   

Cause 

For some reasons, the "Show Sheet Header" could be deactivated in an app. "Advanced Options" is invisible when this happens, because it is located in the sheet header that is removed. The app looks like this in editing mode:

This document is a general guide and is provided as is. Modifications to the process may be necessary depending on your individual database setup.

If you have installed a standalone PostgreSQL database, or if you have used the Qlik PostgreSQL Installer (QPI) to upgrade and decouple your previously bundled database, then you can upgrade PostgreSQL at any time. This means you control maintenance and can immediately react to potential PostgreSQL security concerns by upgrading to a later service release or a later major version.

Content

• Requirements:
• Preparation
• Upgrading to a later service release
• Upgrading to a new major PostgreSQL release

Requirements:

• Only upgrade to a supported version of PostgreSQL. See the Qlik Sense Enterprise on Windows System Requirements for details. 
• This guide covers deployments where PostgreSQL has been installed separately or previously unbundled using the Qlik PostgreSQL installer. 

This document covers the following scenario:

• Windows Server OS. The use of Linux, in managed cloud deployments or on-prem, is not covered. 
• Generic PostgreSQL deployment. Stream replication, SSL, or any other advanced configuration are not covered.

Preparation

Run a complete backup of Qlik Sense Enterprise on Windows site as described in Backup and restore Qlik Sense Enterprise on Windows.

• Qlik Sense Repository Database (from PostgreSQL database server)
• Qlik Sense share folder
• Qlik Sense CA-signed certificates

Upgrading to a later service release

These steps apply if you are upgrading within a major PostgreSQL release (example: 14.5 to 14.8). 

1. Download the PostgreSQL installer from them PostgreSQL site
2. Stop the Qlik Sense Enterprise on Windows services. Leave your standalone PostgreSQL database running.
3. Run the PostgreSQL installer and follow the instructions.
4. Start the Qlik Sense Enterprise on Windows services.

No further steps are required.

Upgrading to a new major PostgreSQL release

If you are moving to a higher major version, an in-place upgrade will not be possible. Instead, we will install the the new version in parallel, then then migrate the old database and eventually uninstall the old version. Our example is written using PostgreSQL 12 to 14. 

1. Download the PostgreSQL installer from them PostgreSQL site
   
   
2. Run the installer
   
   During install:
   
   
   • Install the database on the standard 5432 port. 
     
     This allows us to have 12 running on the Qlik Sense default 4432 port and the 14 instance on 5432.
     
     
   • Set the same password as the one currently in use with the version 12 PostgreSQL instance. 
     
     
3. Open a Windows File explorer and create a backup folder, such as C:\backup 
   
   
4. Backup your version 12 database 
   
   This step is crucial. You may have already backed up your site, but in this step we will create the specific backup we will use to migrate your database, using a modified command.
   
   To do so:
   
   
   1. Stop all Qlik Sense Enterprise on Windows services on all nodes. Leave postgresql-x64-12 service (your current repository) running
      
      
   2. Stop postgresql-x64-14 (your newly installed PostgreSQL instance)
      
      
   3. Open a Windows Command Line (CMD) as administrator
      
      
   4. Run:
      SET PGPASSWORD=postgrespassword (replace this with the actual password)
      
      
   5. Run:
      cd “C:\Program Files\PostgreSQL\12\bin”
      
      
   6. Run
      pg_dumpall.exe -h localhost -U postgres -p 4432 -f c:\backup\backup_db.sql
      
      
   7. Follow the onscreen instructions and wait until the backup is finished
      
      Note: If you are prompted to input the password (even if it was previously entered correctly), you will need to modify pg_hba.conf. 
      
      Location: C:\Program Files\PostgreSQL\12\data\pg_hba.conf
      
      Change md5 to trust and restart the postgresql-x64-12 service. See Changing the Database Superuser Password without Qlik Sense Installed for details.
      
      Once the backup has completed, revert back to md5.
      
      
5. Migrate from 12 to 14
   
   We are now moving our Qlik Sense repository from the earlier release of PostgreSQL into the new one.
   
   
   1. Start the postgresql-x64-14 service
      
      
   2. Stop postgresql-x64-12
      
      
   3. Open a Windows Command Line (CMD) as administrator
      
      
   4. Run:
      cd “C:\Program Files\PostgreSQL\14\bin”
      
      
   5. Run
      psql -h localhost -U postgres -p 5432 -f c:\backup\backup_db.sql
      
      
   6. Follow the onscreen instructions.
      
      Note: If you receive the error password authentication failed for user "postgres", (even if it is correct), you will need to modify pg_hba.conf. 
      
      Location: C:\Program Files\PostgreSQL\14\data\pg_hba.conf
      
      Change scram-sha-256 to md5 and restart the postgresql-x64-14 service  and redo step e). See Changing the Database Superuser Password without Qlik Sense Installed for details.
      
      
6. With the import finished, copy the following two files from your old 12 data folder into your new 14 data folder:
   
   
   • pg_hba.conf 
   • postgresql.conf 
     
     
7. Open postgresql.conf and verify that the port is set to 4432 (the standard Qlik Sense port)
   
   
8. (If not done already) stop the postgres-x64-12 service
   
   
9. Restart the postgres-x64-14 service
   
   
10. Start all Qlik Sense services
    
    
11. Once you have confirmed all functionality and tested, uninstall PostgreSQL 12. This can be done directly from the Windows Control Panel and Programs and Features

It is common to override Talend Studio jars with external/new jars, as demonstrated in the documentation page titled "Customizing the Maven URI for External Module Deployment".

However when trying to override a jar with another jar that is already installed in Studio, you will get in the error below. In the example below, the goal is to replace all references to Snowflake JDBC 3.13.30 with Snowflake 3.13.29. Both drivers are already installed in Studio/exist in the .m2 folder.

To get to the window above, navigate to Window | Show View in Talend Studio and choose Modules:

Open the Module view in the bottom, click on the Maven URI/component you want to customize and click the "..." button.

To point all references of Snowflake JDBC from version 3.13.30 to 3.13.29, remove the value of the Module File, check the Custom MVN URI, and enter the path of the existing module into the URI field. Below is an example that demonstrates the addition of the complete maven path for the Snowflake 3.13.29 driver.

NOTE: This change will affect all components that reference the jar. In the example below, 11 components utilize Snowflake JDBC 3.13.30. If you confirm the aforementioned selection, all 11 components will switch to using JDBC 3.13.29. It is not possible to selectively update specific components that rely on 3.13.30 to use 3.13.29, all 11 references will change.

Once you click the "OK" button, all references will change. As demonstrated below, all modules that were previously pointing to 3.13.30.jar will now use the Maven URI for 3.13.29.jar.

If the module needs to be reverted, simply return to the same window and uncheck "Custom Maven URI".

When an ODBC connector crash occurs in Qlik Data Gateway — Direct Access, other concurrent reloads may be impacted following the original crash. This will specifically be the case if Process Isolation is not enabled. 

To verify if there are ODBC connector crashes:

1. Go to the DAG (Direct Access Gateway) folder: C:\Program Files\Qlik\ConnectorAgent\data\logs\
2. From there, use any file search tool and search for “has exited” entries in the DirectAccessAgent log files, an example:
   
   [Manager ] [WARN ] ODBC process (2172) has exited (exit code: 0), going to restart it...

Multiple connector crashes can have a big impact on the stability of the Direct Access Gateway. 

Resolution

Enable Process Isolation as documented in Mitigating connector crashes during reload. 

Cause

Some crashes can occur due to malformed queries, refer to the Data Gateway - Direct Access. Initial validation for ODBC crashes article.

If there are other crashes without traces that could explain their nature, enable dump file creation, collect the dump files and necessary information for DAG cases and contact Qlik Support.

If a tenant previously had an incomplete SMTP configuration with their Qlik Cloud, an error message will now be shown to the Tenant Administrator:

• Your email providers is not working – Go to Settings 

Resolution

To resolve this error a Tenant Admin can enter valid SMTP credentials. 

At the moment, it is not possible to delete/clear the previous credential entry in the authentication.  An option to clear the credentials is being prepared to support a return to a default (non-configured/empty) state and is expected to be available in the coming weeks.

We will update this article when the ability to clear becomes available. 

Example SMTP Error

Cause 

With the release of the SMTP service connectivity for Microsoft O365 from the Management Console, more stringent error checking was added to the basic authentication configuration.
