Name of the default database established each time a user with this profile logs onto the database.
database_name should be an existing database. The system returns an error when a user with this profile tries to create or reference an object within a nonexistent database.
If the default database is NULL or is not defined in the profile assigned to a user, Vantage uses the setting defined for the individual user. If a default database is not specified for the profile or user, the system uses the username as the default database.
A user can also use SET SESSION DATABASE to specify an alternate default database.
