You transfer the database instance to the ONLINE operational state.

You also use this DBM command when the database was not stopped correctly because the computer was shut down by a power outage. If the volumes of the database instance are undamaged, the system uses the information still available within the system to repeat completed transactions and roll back incomplete transactions.

If you enter a point in time in the DBM command, only the transactions completed up to that time are repeated.

You can also configure a database instance so that it starts automatically when the database computer is started.
