SAP MaxDB Automating Administration Tasks

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 Automating Functions

• Automatic extension of the data area (database size)
• Automatic Log Backup
• Automatic update of the SQL optimizer statistics

 

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.

 

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

 

Using the DBA Planning Calendar

In SAP systems, you can plan periodic administration tasks with the DBA Planning Calendar.
