# System-level properties

When you create users with system-level properties, those users are available to all databases in the system.

You set the value of this system-wide property once for each user, so you can set it several times. To delete a user, remove that user from the file.

You can define this property in the usual ways- typically in the derby.properties file. For more information about setting properties, see Tuning Java DB.

Here is a sample excerpt from the derby.properties file:

    # Users definition
    #
    derby.user.sa=derbypass
    derby.user.mary=little7xylamb
