See the CREATE CATALOG statement for details.

    If you want to specify a CREATE CATALOG statement in a CREATE
    DATABASE statement, you must first specify a MULTISCHEMA IS ON
    clause in the same CREATE DATABASE statement.

    The CREATE CATALOG statement is committed immediately and cannot
    be rolled back. Before you specify the CREATE CATALOG statement,
    the following conditions must be true:

    o  The database is enabled for multischema.

    o  No transactions are active.

    o  The catalog alias must be the same as the database alias.

    For information about enabling the database for multischema, see
    the User_Supplied_Names HELP topic.
