DTS Oracle Connection - Importing Data

I have SQL Server 2000 and am using DTS to simply import some data located on a remote Oracle DB.

If I have the following information:

TNS Name:

 ThisApp.world
 (DESCRIPTION =
 (ADDRESS_LIST =
 (ADDRESS =
 (COMMUNITY = tcpxxx.world)
 (PROTOCOL = TCP)
 (Host = SomeHost)
 (Port = 1234)
 )
 )
 (CONNECT_DATA =
 (SID = App)
 (GLOBAL_NAME = ThisApp.world)
 )
 )

And I also have the name of the Table.

Using the DTS Wizard, on the Choose a Data Source screen, I pick the following:

Data Source: Microsoft ODBC Drive for Oracle
Server:
Username:
Password:

I don't know what I should put into the other fields, given what I have above, i.e. what to put in for Server, Username, and Password! Or should I use a different procedure to import this Oracle data? I am almost positive I was not supplied the username/password. I was told I could connect given the above TNS information. What do you all recommned?

Your assistance will be greatly appreciated.Given the above information, how can I use Server Explorer in VS.NET 2002? It still prompts me for a Username/Password, which I do not have.

Please help anyone.
