====== The Oracle Scheduler (dbms_scheduler) ======

**dbms_scheduler** is a full job scheduler built into the Oracle database since version 10g Release 1. It is a more robust and fully-featured replacement for the old, primitive dbms_job scheduling system.

I have been a primary contributor to this since January 2001. This is a collection of public info pertaining to the Scheduler collected in one place.
