I’m lazy, why doesn’t anyone have instructions I can follow already! I guess it’s time to give back to the Google seekers of this world. After going through the process I can understand why no one has written a guide, it’s not a straight forward process.
As this sort of thing can be very version specific I tested these instructions using the following versions of software
- Windows Server 2012 R2 running on AWS
- Qlik Sense 2.2.4
- Oracle instant Client version 188.8.131.52.0 64bit
Two things need to be downloaded for this to work from here Instant Client Downloads for Microsoft Windows (x64)
- Instant Client Package – Basic
- Instant Client Package – ODBC
Once you have the files follow the steps below to get things working:
- Unzip the instantclient-basic-windows.x64-<version number>.zip
- Move the folder instantclient_<version number> into a permanent location. In my case c:\app\
- Edit the system environment variables on the server add the folder location to the end of the PATH variable. eg %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\Amazon\cfn-bootstrap\;C:\app\instantclient_12_1
- Add new system variable
Variable Value: <Path to where you want to store tnsnames.ora file>
- Create a text file called tnsnames.ora in the folder specified in step 4 and create an entry for your desired DB which should follow the below format
<addressname> = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(Host = <hostname>)(Port = <port>)) ) (CONNECT_DATA = (SERVICE_NAME = <service_name>) ) )
- Unzip instantclient-odbc-windows.x64-<version number>.zip
- Move the contents of the instantclient_<version number> folder into the instantclient_<version number> folder from step 2
- Run instantclient_<version number>\odbc_install.exe
- To test if things work setup an odbc Data Source (64-bit) as a System DSN and test the conneciton.
- You may need Microsoft Visual C++ 2010 SP1 Redistributable Package (x64) if you have the below error when adding a new ODBC Data Source.
- In Qlik Sense you can create a new connection at this point ODBC driver. If you get an error message “You do not have access to the data source” as I experienced the only solution that worked for me was in this post and the solution wasn’t ideal. I intend to talk to Qlik to see if there is a better solution.
