Hi Nirmal,
You cant see whether drivers installed or not in the PI tools which used for developing the integration scenario.Drivers will be deployed in the PI Java runtime which you will not have access.Please check with your basis team.
I understand you are beginner to SAP so i would suggest to read the sap help for configuring the JDBC adapter.
Simple way to check whether JDBC drivers deployed in PI is try co create a scenario in PI which inserts or fetches data from and to data base.
Thanks
