Unable to Connect Oracle DB - Is Katalon Enterprise License Required?

Hi All,

I have downloaded Katalon Studio 8.1.0 Trial Version it was expired and again I have downloaded with other account and using it. Now I am Unable to Connect to Oracle DB -
Is License Required in order to connect to the same? PFA screen shots.

Connecting to a database with an external JDBC driver is an Enterprise feature, so a licence is required.
However, Oracle database should work with the builtin driver, which is a free feature, see:

So, try to leave the JDBC driver field empty when you are configuring the connection.
