Oracle scheduler allows event-based job control

Dr. Tim Hall, author of the bestselling book Oracle Job Scheduling has just published examples of the new Oracle10g release 2 scheduler enhancements:

Dr Hall notes several important enhancements to the Oracle10g scheduler functionality, (DBMS_SCHEDULER, DBMS_RULE_ADM) that make external job control with crontab scheduling largely obsolete.  This is a bold move by Oracle that will create a full job control environment, analogous to MVS JCL.  Here are Timís notes:

Jobs That Raise Events

Individual jobs are instructed to signal specific events by setting the RAISE_EVENTS attribute. Events are placed on the scheduler event queue, which is available to applications that subscribe to the queue. The following code sets up a test user and grants the necessary privileges.

Event-Based Jobs

In addition to raising events, it is possible to define jobs that are run in response to events, know as even-based jobs. The following code sets up a test user and grants the necessary privileges.

Job Chains

Job chains allow multiple jobs to be linked together for form dependency chains.

Miscellaneous Scheduler Enhancements

  • Access to external jobs has been separated from internal jobs. The CREATE EXTERNAL JOB privilege is necessary to define jobs that run OS commands and executables.
  • The "freq=" clause of the calendaring syntax now accepts named schedules as well as predefined frequencies, allowing user defined frequencies.
  • The calendaring syntax allows schedules to be combined using set operators such as INCLUDE, EXCLUDE and INTERSECT to form complex schedules.
