Here is a summary of the responses I received to the MDQS - User Survey that was posted Oct 24, 1986. 1. What version of MDQS are you running? Versions 2.8, 2.9, 2.10, and 2.11(Released Oct 1986). 2. What machines/operating system versions does your MDQS run on? Celerity 1230 running 4.2 BSD Cray-2 running UNICOS -- a SysV OS HP 9000-300 running HP-UX. ISI 68K based unix system. Onyx C8002M running Sys III/Onix 3.0.3 Perkin-Elmer 3210 running SV SUN 2/120, 3/50, 3/180 Sperry 1100/80 (mainframe) under "1100 OS" (known also as "EXEC 8"). Vax 11/750 running SysV Vax 730, Vax 750, Vax 780, Vax 785 running BSD 4.[123] Zenith Z-151(PC/XT) running Venix 2.0 3. Do you have MDQS in a network setup? (Inter-machine queueing) If so, what kind of networks are supported under MDQS? Several sites do not use MDQS over any networks. Ethernet networks are most common. TCP/IP protocols are most common. Some sites are using UUCP with the 't' TCP/IP protocol or the old 'g' protocol. Most MDQS environments have mixed machine/operating systems on networked machines. 4. What modifications have you made to MDQS? Most users made no major changes to the MDQS version they run. Many users have implemented servers to different devices. Known devices are: Versatec, servers: unix-plot, versaplot, vcat(CAT emulation), line-printer. QMS 800/1200/2400 laser-printers, servers: line-printer, lgcat(CAT emulation) Printronix line-printer, servers: line-printer/plotter LN01 laser-printer HP Laserjet+, servers : DVI driver XEROX penquine Imagen laser-printers NEC Spinwriters 5515, 5520, 7715, 7725 spinwriters Teletype 40 chain printer Smartwriter Data Products 2610 Laserwriter w/Postscript Okidata 82, 92, 292 C.Itoh 8510 Gencom 3404 DEC LN03 One MDQS user supports printers connected to AUX ports on terminals. MDQS modifications include: load limit control for MDQS devices: device will not be activated if load average is above limit value. mdqsdaemon will service multiple queues per device equally device shutdown option to qdev: disable device but allow the current job to complete. added message to disable/shutdown option of qdev added stty options to print servers added environment variable setting for shserver made no copy option default for qpr. fixed bugs(I will notify BRL about these) only privileged users can use higher priorities on jobs. handle Sys V process groups fix servers to restart print jobs on write failures. 5. What features would you like to see in MDQS? The most common topic was improved network support. EG: qstat(1), qmod(1), qdev(1) that work across network of systems. I will be conversing with BRL on this topic also. Other features of interest are: Remote job entry support: Remote 'batch' with staging and return of files. Better shutdown and restart facilities: (e.g., restart after a paper jam by backing up 5 pages). I have begun to converse with BRL about these results, and I will post further details to comp.sources.d as progress is made. I would like to see all of the modifications incorporated into the next MDQS release. I am hoping to get the network support issue address somewhat also in the next release.
