    RDB$LOGICAL_AREA_ID  RDB$AREA_ID  RDB$RECORD_LENGTH  RDB$THRESHOLD1_PERCENT
     RDB$THRESHOLD2_PERCENT  RDB$THRESHOLD3_PERCENT  RDB$ORDERED_HASH_OFFSET
      RDB$RECORD_TYPE  RDB$LOGICAL_AREA_NAME
                     95            7                 41                       0
                          0                       0                        0
