Automating Administration Tasks
Context
As a database administrator, you must periodically carry out certain administration tasks. In addition to these, you may need to carry out further administration tasks after specific system events have occurred.
Some administration tasks can be automated using special automating functions, others can be planned with the scheduler, triggered by events or triggers, or planned with the DBA Planning Calendar.

- Using the Scheduler
You can use the scheduler to schedule DBM commands to be executed at specific times. For that purpose, you log on to the database and create a job in the scheduler for every DBM command to be executed. You must activate the scheduler for the jobs to be executed.
The scheduler uses a separate DBM server process for the connection to the database. Therefore, the scheduler remains active when you stop the database.
For more information, see Database Manager CLI, Using the Scheduler Function.
- Using Database Events
You can define that database events are triggered under specific circumstances, and that certain actions are carried out in response to these events, for example sending an e-mail, executing a DBM command or executing a command from another program.

- Using Database Triggers
You can use database triggers to trigger actions in the database following certain data changes or a restart.
For more information, see SQL Reference Manual, Trigger Name (trigger_name).
- Using the DBA Planning Calendar
In SAP systems, you can plan periodic administration tasks with the DBA Planning Calendar.
