In addition to creating linked servers using SQL Server Management Studio (SSMS) you can create linked servers using T-SQL commands. T-SQL offers several advantages over SSMS. T-SQL scripts are self-documenting, letting you easily see how the linked servers are created. They can also be easily copied and rerun if you want to create a new linked server or recreate an old linked server.
To create a new linked server named OR-PORT-VORA11G, you can use the command
@srvproduct=N'OraOLEDB', @provider=N'OraOLEDB.Oracle', @datasrc=N'ORCL'
