OEM 12 C Job System

Purpose:

The Enterprise Manager Job System serves these purposes:

Automates many administrative tasks; for example: backup, cloning, and patching Enables you to create your own jobs using your own custom OS and SQL scripts

Enables you to create your own multi-task jobs comprised of multiple tasks

A job is a unit of work that you define to automate commonly-run tasks. Scheduling flexibility is one of the advantages of jobs. You can schedule a job to start immediately or start at a later date and time. You can also run the job once or at a specific interval, such as three times every month.

The Job Activity page is the hub of the Job System. From this page, you can:

Search for existing job runs and job executions filtered by name, owner, status, scheduled start, job type, target type, and target name

Create a job

View or edit the job definition

Create like, copy to library, suspend, resume, stop, and delete a job

View results, edit, create like, suspend, resume, retry, stop, and delete a job run or execution

Besides accessing the Job Activity page from the Enterprise menu, you can also access this page from any Database or Cluster Database property page (Home, Performance, Availability, and so forth) by selecting Job Activity from the Oracle Database menu. When you access this page from these alternate locations, rather than showing the entire list of jobs, the Job Activity page shows a subset of the jobs associated with the particular target.

Job Type

Using the Job System, you can create a job by selecting one of the job types from the Create Job drop-down in the Job Activity page. The most commonly used types are as follows:

• OS CommandRuns an operating system command or script.

• SQL ScriptRuns a user-defined SQL or PL/SQL script

• RMAN Script:Runs a Rman backup job

• Startup DatabaseRuns a database startup operation for the attached databases.

• Shutdown DatabaseRuns a database shutdown operation for the attached databases.

• Multi-Task

Use to specify primary characteristics for multi-task jobs or corrective actions. Multi-task jobs enable you to create composite jobs by defining tasks, with each task functioning as an independent job. You edit and define tasks similarly to a regular job.
