Start a Database

This article explains how to start a database.

For Exasol 2025.1 and later, you can use Exasol Admin to start and stop databases. For earlier versions, you must use either ConfD or the Administration API.

Procedure

The Start button shown triggers a startup of all database instances on the active nodes of the cluster. This has the same effect as the action Startup that can be selected on the database page. A special case is Startup Maintenance on the same page: It allows connections with any password, which can be helpful if the password of the sys user was forgotten but imposes a security concern otherwise.

Restart essentially triggers a Shutdown followed automatically by Startup. Difference is that the Restart doesn’t obtain the License value from the License Server like the sequence Shutdown->Startup does.
