How to use "Connect" activity to Connect to ORACLE Database ?What are the software needed on the windows machine?

I am new to UIPath and tried to use “Connect” activity to connect to Oracle Database . I read some of the answers in the forum , but failed to connect through Uipath studio.
Can you please explain the steps needed after pressing “Configure connection” in the “connect” acvtivity? What are the software setup needed(if any needed) in my windows machine -Server 2012 R2, like drivers , client tools etc ? What is the general syntax of the “Connection string” used in the “Connect” activity to connect to a ORACLE Databse?
Will you please explain step by step to understand by any beginner.
