DBM operators manage databases using the tools Database Studio or Database Manager CLI. When a database is created, an initial DBM operator (first DBM operator) is created who has the required DBM operator properties and all server authorizations. There can be several DBM operators per database.

The default value for the name of the first DBM operator is DBM, in SAP systems CONTROL.

The database system administrator also has all DBM operator authorizations.

Note that DBM operators are not database users. They can neither change data in the database nor log on to query tools or the Loader.

Description

Disabled

Specifies whether the user account of the DBM operator is locked

Enable Second Password

You can also define a second password. This way you can temporarily allow other people to work with the DBM operator account (for example, for support purposes) without the DBM operator having to reveal or change the original password.

Managing DBM Operators

If DBM operators have the required DBM server permissions, they can create other DBM operators, change DBM operator properties and DBM server permissions of other DBM operators, or delete other DBM operators.

If you change the name or properties of another DBM operator or delete it while this operator is logged on to Database Manager using a different DBM server process, the change or deletion does not become effective within this DBM server session. Only when this operator logs on again to Database Manager, the new name or property definition becomes effective. If the operator was deleted, it cannot log on to Database Manager any more.

You have the following options for displaying and managing DBM operators:
