Error: Connector connect error: Error starting QvConnect process: Instance 'QvOdbcConnectorPackage#1' does not exist in the specified Category.

Qlik Sense connector (from the ODBC connector package like for example Oracle, MS SQL, Hive, Redshift, etc...) fails randomly with the following error message which can be found in the script and the Qlik ODBC connector package log:

Error: Connector connect error: Error starting QvConnect process: Instance 'QvOdbcConnectorPackage#1' does not exist in the specified Category.

 

Environment

 

 

Resolution

 

The issue is related to a software defect and has been solved in the Qlik Sense version August 2021.

Upgrade your Qlik Sense version to any version after Qlik Sense August 2021. The ODBC connector package will be automatically upgraded as well.

 

Workaround:

Besides doing an upgrade to Qlik Sense August 2021, there are the following workarounds available:

  1. Check if the affected connector has a connector reading strategy "engine" if yes, then try to change it to "connector", like for example  " <add key="redshift-reading-strategy" value="connector" />" (this can be done in the config file " QvOdbcConnectorPackage.exe.config" under "C:\Program Files\Common Files\Qlik\Custom Data\QvOdbcConnectorPackage"
  2. Try to add "<add key="QlikEngineLocation" value="C:\Program Files\Qlik\Sense\Engine\QvConnect64.exe" />" in the ODBC connector package config file

 

Fix Version:

Qlik Sense August 2021

 

Cause

Thanks @Andreas_Giesbrecht 

can you provide more details on:

  1. Just upgrade of the Qlik ODBC connector package to the version of Qlik Sense August 2021

What is the correct procedure to upgrade the ODBC connector package?

Would this impact in some way the QS version upgrade?

Best,

Moreover, considering this post

https://community.qlik.com/t5/Connectivity-Data-Prep/Is-it-possible-to-upgrade-the-ODBC-Connector-Pa...

the ODBC connector upgrade is possibile but not recommended nor supported.

Thanks.

Hello @Giovanni_Civardi 

We've put together an article that will hopefully help you with that question: How to upgrade the Qlik Sense Enterprise on Windows ODBC Connector Packages  

The highlights: While we don't recommend upgrading the package by itself, it is doable. Just make sure to backup the current version as you will need to restore it when upgrading Sense (or for troubleshooting).

All the best,
Sonja
