In normal operation, databases are in the ONLINE operational state. You can either manually start databases (transfer them to the ONLINE operational state), or activate automatic startup.

To perform certain administration tasks such as restoring a database after a system failure, the ADMIN operational state or a restart of the database may be required.

Prerequisites

  • You are logged on to the database as database system administrator or as a DBM operator with server authorization for starting and stopping the database.
