Oracle Database includes Oracle Scheduler which provides the functionality of job scheduling through DBMS_SCHEDULER PL/SQL package.
We can have Event Based scheduling option in which job fires based on particular event occurrence.
For example, starting 11.2, a new feature has been introduced to signal the scheduler whenever file arrives to either local or remote system. This feature is known as "File Watcher".

This note describes the situation where sometimes job doesn't get trigger for some moved or copied files.
