Predefined Job Classes with Oracle Scheduler

Autonomous Database includes predefined job_class values to use with Oracle Scheduler.

The predefined job_class values, TPURGENT, TP, HIGH, MEDIUM and LOW map to the corresponding consumer groups. These job classes allow you to specify the consumer group a job runs in with DBMS_SCHEDULER.CREATE_JOB.

The DBMS_SCHEDULER.CREATE_JOB procedure supports PLSQL_BLOCK and STORED_PROCEDURE job types for the job_type parameter in Autonomous Database.

For example: use the following to create a single regular job to run in HIGH consumer group:

BEGIN
   DBMS_SCHEDULER.CREATE_JOB (
     job_name => 'update_sales',
     job_type => 'STORED_PROCEDURE',
     job_action => 'OPS.SALES_PKG.UPDATE_SALES_SUMMARY',
     start_date => '28-APR-19 07.00.00 PM Australia/Sydney',
     repeat_interval => 'FREQ=DAILY;INTERVAL=2',
     end_date => '20-NOV-19 07.00.00 PM Australia/Sydney',
     auto_drop => FALSE,
     job_class => 'HIGH',
     comments => 'My new job');
END;
/

Notes for Oracle Scheduler:

• To use DBMS_SCHEDULER.CREATE_JOB additional grants for specific roles or privileges might be required. The ADMIN user and users with DWROLE have the required CREATE SESSION and CREATE JOB privileges. If a user does not have DWROLE then grants are required for CREATE SESSION and CREATE JOB privileges.

• The instance_id job attribute is ignored for Oracle Scheduler jobs running on Autonomous Database.

See Scheduling Jobs with Oracle Scheduler for more information on Oracle Scheduler and DBMS_SCHEDULER.CREATE_JOB.

See SET_ATTRIBUTE Procedure for information on job attributes.
