481.0. "RMS_HEURISTIC and RMS_DFLRL?" by GIDDAY::GILLINGS (a crucible of informative mistakes) Wed Apr 16 1997 00:51

  Section 3.16.8 in the OpenVMS V7.1 New Features Manual describes the
  new SYSGEN parameters RMS_HEURISTIC and RMS_DFLRL SYSGEN parameters. 
  These appear to help deal with the dreaded RMS-W-RTB error when trying
  to use RMS to process a file from a PC or Unix system. Since this condition
  results in *lots* of service calls, and there is no simple "fix", anything
  to help would be very welcome in the CSC. 

  However, in experimenting, I can't find any difference between having the
  parameters on or off. 

  Consider a file RFM=STM, LRL=0, MRS=0. When I attempt to TYPE the file
  I get the following results:

  File size < MAXBUF	     => File is displayed

  MAXBUF < File size < 32767 => %TYPE-F-WRITEERR, error writing SYS$OUTPUT:.;
				-RMS-F-SYS, QIO system service request failed
				-SYSTEM-F-EXQUOTA, process quota exceeded

  File size > 32767 	     => -RMS-W-RTB, 291966 byte record too large for user's buffer
				%TYPE-F-WRITEERR, error writing SYS$OUTPUT:.;
				-RMS-F-RSZ, invalid record size

  This behaviour seems to be independent of the setting of the RMS parameters.

  Could someone please give an example of what these parameters are supposed
  to do? What have I missed?

    What is RMS_DFLRL set to?
    
    Is the file a "normal text file"? (No, I don't know how RMS defines
    that.)
