I have an old program which uses cx_Oracle with Oracle 11g. This program is not portable as the user need to download Oracle 11g in order to use it. Is it possible to use Oracle database in my script but without downloading it, may be by using any online database?
After reading your problem, What I understood is that you need a portable database. Since your scripts are connected to Oracle 11g with cx_Oracle , I guess you used SQL queries everywhere. I suggest you to use SQLite instead of cx_Oracle if you are in a hurry. Both have kinda similar syntax for executing queries though you may need to modify some keyword. To start quickly refer https://docs.python.org/3/library/sqlite3.html
