In Oracle Database 10g, automatic optimizer statistics ran as a Scheduler job named <code>GATHER_STATS_JOB</code>, and you turned it on or off with <code>DBMS_SCHEDULER.ENABLE</code> and <code>DBMS_SCHEDULER.DISABLE</code>. From 11g, the same work runs as an automated maintenance task (AutoTask) named <code>auto optimizer stats collection</code>, and you control it with <code>DBMS_AUTO_TASK_ADMIN</code>. A script that calls <code>DBMS_SCHEDULER</code> on a modern database is aiming at the wrong object.</p>
