Transferring tables between SQL Server and Oracle

I want to copy a few tables from a database on SQL Server 2000 to a database on an Oracle server on a daily basis. I tried DTS, but it was extremely slow (took about 6-7 hours to transfer five tables). The tables have about 50,000 records each. Can you suggest some way to do this?

The speed issue is not due to SQL Server or DTS. It is within the Oracle connection libraries. In order for DTS to move data directly, it must transit multiple connection libraries and data format protocols. You can avoid that be taking a page from the systems book from 20+ years ago. Export your table to a text format that can be understood by Oracle, transfer the files to your Oracle system, and then use SQL Loader on your Oracle system to import the text files.
