# derby.database.defaultConnectionMode

#### Function

One of the user authorization properties.

Defines the default connection mode for users of the database or system for which this property is set. The possible values (which are case-insensitive) are:

- noAccess

  Disallows connections.

- readOnlyAccess

  Grants read-only connections.

- fullAccess

  Grants full access.

If the property is set to an invalid value, an exception is raised.
Note: It is possible to configure a database so that it cannot be changed (or even accessed) using this property. If you set this property to noAccess or readOnlyAccess, be sure to allow at least one user full access. See derby.database.fullAccessUsers and derby.database.readOnlyAccessUsers.
For more information about user authorization, see "User Authorization" in Chapter 7 of the Java DB Developer's Guide.

    CALL SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY(
        'derby.database.defaultConnectionMode',
        '{ noAccess | readOnlyAccess | fullAccess}')

#### Example

    -- database-wide property
    CALL SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY(
        'derby.database.defaultConnectionMode', 'noAccess')
    -- system-wide property
    derby.database.defaultConnectionMode=noAccess

#### Default

#### Dynamic or static
