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

Create a database link from Oracle to Sql Server (heterogeneous connectivity). You can use this link to retrieve the data from Sql Server with a simple select statement. If you want to schedule you can use a materialized view or dbms_scheduler.

An alternative is to put your data in a csv file, you can use an external table or sqlloader to load this data in the Oracle database.
