You can launch executable files and shell scripts and run database procedures automatically.
Jobs are configurable as Web Services to provide interoperability with enterprise applications.
Mode of Operation:

Job Execution:
The Job Scheduler processes sequential and parallel tasks. Jobs can be organised in job chains to ensure sequential processing and can be run in multiple instances for scalability. Triggering of job starts is done by directory notification, built-in calendars and via web user interface or use of the Job Scheduler API by other applications (Java, scripting languages).
Supported Platforms:
The Open Source Job Scheduler is working for the following operating systems:
Windows 2000/2003/XP, Linux starting with kernel 2.4, Solaris 8/9/10 and HP-UX 11.
