    DM1541 for DB2 for z/OS V10: A new DB2-supplied stored procedure
    has been implemented to set the internal option to disable
    recording of temporal history for a system-period temporal
    table and allow values to be specified for the special
    temporal column types previously mentioned. The DB2-supplied
    procedure is named,
    SYSPROC.SET_MAINT_MODE_RECORD_NO_TEMPORALHISTORY.
    
    This stored procedure is not intended for general use.  It is
    intended to be used by products that enable DB2 replication.
    
    When this procedure is invoked by a connection, DB2 behavior
    (for static and dynamic SQL) is affected as follows:
    1, historical rows are not written to a history table for
    update or delete operations.
    2, an application may specify values (such as in an INSERT
    statement or UPDATE statement) for a row-begin, row-end, or
    transaction-start-ID column even though the column is defined
    as GENERATED ALWAYS, and these values will be stored in the
    affected rows.
