Prerequisites

Make sure the following prerequisites have been met:

Qlik Replicate for Windows

Install Microsoft ODBC Driver 18.1 for Windows on the Qlik Replicate Server machine.

Qlik Replicate for Linux

The procedure below assumes that you have installed a single default instance of Replicate on Linux (areplicate). If you have installed multiple instances, replace areplicate with the name of the instance running the task with a Microsoft SQL Server source. If several instances are running such as task, the procedure needs to be repeated for each instance.

Install Microsoft ODBC Driver 18.1 for Linux on the Replicate machine.

Then, open a Unix shell and do the following:

  1. Change the working directory to <Replicate-Install-Dir>/bin.

  2. Stop the Replicate service:

    ./areplicate stop

  3. Optionally, confirm that the service has stopped:

    ./areplicate status

  4. Copy the driver location to the site_arep_login.sh file as follows:

    echo "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/microsoft/msodbcsql18/lib64/" >> site_arep_login.sh

    This will add the driver to "LD_LIBRARY_PATH" and update the driver location in the site_arep_login.sh file.

  5. Optionally, confirm that the driver location was copied:

    cat site_arep_login.sh

  6. Start the Replicate service:

    ./areplicate start

  7. Optionally confirm that the service has started:

    ./areplicate status

  8. Replicate requires the following ODBC library: libmsodbcsql-18.1.so.1.1

    To check which library version is currently installed Issue the following command:

    ls /opt/microsoft/msodbcsql/lib64/

    If the existing library has a different version number (e.g. libmsodbcsql-18.0.so.1.1), you need to create a symbolic link between the existing library and the required library.

    To do this, issue the following commands:

    cd /opt/microsoft/msodbcsql18/lib64/
    ln -s existing_library_name libmsodbcsql-18.1.so.1.1

    where existing_library_name is the name of the currently installed library (e.g. libmsodbcsql-18.0.so.1.1).

TLS 1.2 prerequisites

If your environment matches the following:

  • Microsoft SQL Server 2014
  • Microsoft ODBC Driver 18 installed on Red Hat 8.1 or later

Then, in order to work with TLS 1.2, you must install a specific Service Pack on the Windows machine where Microsoft SQL Server is installed.
