SQL Anywhere 11.0.0 » SQL Anywhere Server - Database Administration » Maintaining Your Database » Automating tasks using schedules and events


Introduction to using schedules and events

Many database administration tasks are best performed systematically. For example, a regular backup procedure is an important part of proper database administration procedures.

You can automate routine tasks in SQL Anywhere by adding an event to a database, and providing a schedule for the event. Whenever one of the times in the schedule passes, the database server executes a sequence of actions called an event handler.

Database administration also requires taking action when certain conditions occur. For example, it may be appropriate to email a notification to a system administrator when a disk containing the transaction log is filling up so that the administrator can handle the situation. These tasks too can be automated by defining event handlers for one of a set of system events.
