  The default path should be:

  Information note

  • The path to the Oracle Data Access DLL also needs to be specified in both the machine.conf file and the Global Assembly Cache (GAC). In addition, make sure that the Oracle.DataAccess.dll file exists in the following location: C:\Windows\Microsoft.NET\assembly\GAC_64.

    For more information, see Oracle Help Center.
    

  • The Qlik Compose service needs to be restarted after installing the required components.
• Install Oracle Instant Client for Microsoft Windows (x64) on the computer where Qlik Compose is located.
