How do I uninstall Solarwinds that has been installed or connected to an Oracle database?

I am testing Solarwinds. I have installed the repository on a SQL Server database and connected to monitor an oracle 11g database. The setup created 15 views and packages in the sys schema in oracle and I want to disconnect this oracle database from Solarwinds. How do remove this database from solarwinds or how do I get rid of all these objects from sys without manually dropping them.

Thanks
