JDBC ADAPTER ERROR IN SAP XI

Hi,

I am working in the following scenery: FILE->XI->JDBC.

I already accomplished all of the configurations in Integration Repository, Integration Directory and System Landscape. When it went to turn the scenery described above appears the following screen enclosed. We are using the database Oracle.

Error

Available JDBC drivers:

No deployed JDBC Drivers found

This drive already default in database Oracle or should we download the drive and to install in the servant of the XI?

Does some note exist to be applied?

Which are the necessary steps to do the deployed of the drive?

Which are the steps to solve this problem?
