How many times have you run the right job with the wrong parameters? The same job multiple times, not at all, or out of order? Have you ever corrupted data by running two incompatible jobs simultaneously?

With JobScheduler for Oracle you register programs once with default parameters (even automatic ones), and then use them in any job. You define Job Streams which run the right jobs in the right order on the right schedule. And you define program incompatibilities which guarantee the integrity of your database.
