I am running Tableau Server on a Linux VM and I am connecting to a DB2. There was a IBM DB2 Driver already installed but my first try to connect to the DB2 failed. After that I installed the IBM ODBC Driver and know it works fine. But I want to ask if there is any possebility for using the IBM DB2 native driver? And if not, what is the reason?
You may need to re-install the drivers. I got our drivers from our IBM DB2 dba team (pSERIES), so we connect natively (not through ODBC). It works fine in our Windows environment. I don't know why it wouldn't work for you.
