Stores existing database system file definitions in the
    repository for the first time. Use the INTEGRATE DATABASE
    FILENAME clause if you did not specify PATHNAME or the repository
    was not installed when you created the database.

    If you use the INTEGRATE DATABASE FILENAME clause, the repository
    database node specified in the path name must not exist. If
    older repository definitions do exist with the path name you
    are specifying, specify a different repository path name, placing
    the new database definitions elsewhere.

    The file-name clause is the full or partial file specification
    that specifies the source of the database definitions. You do
    not need to specify the file extension. The database system
    automatically uses the database root file ending with the .rdb
    file extension.

    Path-name-2 is the repository path name for the repository where
    the INTEGRATE statement creates the database definitions (using
    the database system files as the source). You can specify either
    a full repository path name or a relative repository path name.
    This must be the path name, not the name of the database itself.
