Oracle DBMS_SCHEDULER
Version 12.1.0.1

General Information
Library Note Morgan's Library Page Footer
The Library is currently in the process of being upgraded from Oracle Database Version 11.2.0.3 to 12.1.0.1. Demos are being upgraded to reflect the new Container paradigm as well as EBR (Edition Based Redefinition) and may contain references to CDBs, PDBs, and other objects you may not be familiar with such as CDB_OBJECTS_AE: Welcome to 12c.
Purpose Schedule Jobs based on schedules and events
AUTHID CURRENT_USER
Commit Semantics
Name Description
ABSORB_ERRORS Tries to absorb errors and attempts to make the listed job attribute changes and commits all successful changes
STOP_ON_FIRST_ERROR The default: Returns on the first error and the previous attribute changes that were successful are committed to disk
TRANSACTIONAL Returns on the first error and everything that happened before that error is rolled back

Security Model Owned by SYS with EXECUTE granted to PUBLIC and the APEX_040200, EXFSYS, and ORACLE_OCM roles.
Security Privileges
Privilege Description
Create Any Jobs This privilege enables you to create, alter, and drop jobs, chains, schedules, and programs in any schema except SYS. This privilege is very powerful and should be used with care because it allows the grantee to execute code as any other user.
Create External Jobs Required to create jobs that run outside of the database. Owners of jobs of type 'EXECUTABLE' or jobs that point to programs of type 'EXECUTABLE' require this privilege. To run a job of type 'EXECUTABLE', you must have this privilege and the CREATE JOB privilege.
Create Job This privilege enables you to create jobs, chains, schedules, and programs in your own schema. You will always be able to alter and drop jobs, schedules and programs in your own schema, even if you do not have the CREATE JOB privilege. In this case, the job must have been created in your schema by another user with the CREATE ANY JOB privilege.
Execute Any Class Enables jobs to run under any job class
Execute Any Program Enables jobs to use programs or chains from any schema
Manage Scheduler This is the most important privilege for administering the Scheduler. It enables you to create, alter, and drop job classes, windows, and window groups. It also enables you to set and retrieve Scheduler attributes and purge Scheduler logs.
