Moving Data from SQL Server to Oracle Repeatedly

Question

What are the most reasonable ways to move table data from SQL Server to Oracle (on *nix) on a regular basis?

Answer 1

I had success creating a linked server (from within the Enterprise Manager, I think) to Oracle on the SQL Server side. Then I could use normal stored procedures on both sides to accomplish smaller data movement and updates in both directions. This approach can bypass the need to try and put something together outside the databases.

Try hard to use the latest possible Oracle client on the SQL Server side though. I recall some defects in the 10.2.0.2 client and getting the 10.2.0.4 client required your "official" Oracle registration or purchase number or something.

For big data moves (or maybe even moves/updates you want done on a daily or less frequent basis), definitely use one of the ETL tools. We had Informatica for our ETL processes, but if SSIS can pull off what you need, that's fine too.
