Thank you Lowell. It looks like you have installed the Oracle full client not the Oracle Instant client. Is that correct?
Patti yes, that is correct; we just tend to install the fuller tools.
I googled SQL SERVER +"ORACLE INSTANT CLIENT" and only see one post that was reported working 100%; a lot report problems setting up, which i guess is typical.
make sure you run this for the driver just in case, and then create your linked server the way you were before, i think;
--Required settings for the provider to work correctly as a linked server
EXEC master.dbo.sp_MSset_oledb_prop N'MSDASQL', N'AllowInProcess', 1
GO
EXEC master.dbo.sp_MSset_oledb_prop N'MSDASQL', N'DynamicParameters', 1
a thread here on SSC also suggested using the full version of the drivers, but the OP posted that it worked for him after the commands above.

you could post a follow up in that thread, maybe the OP who installed the light client could script his linked server out as an example?
