Syntax options:

    DICTIONARY IS REQUIRED | DICTIONARY IS NOT REQUIRED

    Specifies whether or not definition statements issued for the
    database must also be stored in the repository. If you specify
    REQUIRED, any data definition statements issued after a DECLARE
    DATABASE statement that does not use the PATHNAME argument fails.

    If you omit the PATHNAME clause from the database root file
    parameters in the CREATE DATABASE statement, SQL generates an
    error if you also specify DICTIONARY IS REQUIRED.

    The default is DICTIONARY IS NOT REQUIRED.
