I created a TabPy Python program to connect to our Oracle database, and retrieve data from it. I used cx_Oracle. The TabPy program was working just fine when I tested it in Jupyter Notebook. But after I deployed it as a TabPy service and tested in with Tableau Desktop, I got this error:
cx_Oracle.DatabaseError: DPI-1010: not connected
Please help me to solve this problem. Thank you very much!
