831.0. "System Management" by CYCLPS::PANGAKIS () Wed Aug 19 1987 19:26

    Does anyone have any recommendations around managing a system with
    heavy use of DOCUMENT (at least 5-10 users trying process files at
    once)? 
    
    I was thinking of installing DOCUMENT on my VAXstation II and
    processing files on it. Taking up CPU time on our main system drives
    other users crazy. 
    
    Has anyone establish any particular procedures for doing this kind of
    thing; is system management documented anywhere?  (I have the ADMIN
    guides, I'm looking mainly for items to help me with system performance.) 
                                                
    Thanks in advance.

831.1SANTEE::GREENEMichael GreeneWed Aug 19 1987 20:3815
    I've got Document running on a VS II, VS 2000 (both standalone) 
    as well as LAVC with 750 and 6xVS2000. (VS2000 with LN03 and DOCUMENT
    makes a great machine to take to shows/conferences for last minute
    presentation overheads!)

    In all cases I'm running with large quotas for eash account in the
    SYSUAF.DAT file and large working sets etc. I've been pretty successful
    at using VPA (VAX Performance Advisor) to help tune these systems.
    At least it seems so... One suggestion I have (haven't had time
    to implement myself due to small event called DECworld)) is to use
    DFS (distrib File System) to keep only one copy of the DOC files
    -- can't see any problems with this and makes system management
    much easier, also cuts down disk space req.

831.2Use Batch Ques...PSYCHE::GRANTI've saved $984.00 since I quit smoking.Thu Aug 20 1987 09:108
Tara,
	Here, in Maynard, we insist on our writers using the BATDOC command.  
This submits a batch job to a que that has a lower priority than interactive 
jobs.  We also limit the number of jobs to two. (One on each of our 11/785's.)
We have 25 to 30 people using DOCUMENT but I've never seen the batch que with
more than one or two jobs pending.  (Except one time when one 11/785 was down.)

831.3Use /BATCHCRAYON::GENTParty gone out of bounds -- B52'sThu Aug 20 1987 09:1613
    If you have more than 1 or 2 jobs at a time, my main suggestion 
    is to insist that your users use the /BATCH qualifier. In fact, 
    I recommend you create a queue at base priority 2 or 3 (not 4) 
    specifically for DOCUMENT use.
    
    To make it easier to use, I also recommend you create a command
    file and define a foreign symbol to replace the DOCUMENT command
    with DOCUMENT/BATCH and the appropriate attributes. Otherwise users 
    find it too difficult to use batch mode. For example:
    
    	$ DOCUMENT/BATCH=(QUE=sdml_batch, notify, noprint)

831.4Need horsepowerMARTY::FRIEDMANThu Aug 20 1987 10:466
    We upgraded from a 785 to an 8700. DOCUMENT is CPU-hungry, so the
    only real way to improve performance is to get a more powerful CPU.
    We hope to upgrade to an 8800 when VMS V5 is available.

831.5let me think awhile on that...VAXUUM::KOHLBRENNERThu Aug 20 1987 14:1715
    THere is not much tuning that can be done, because DOCUMENT
    is asking for the cpu most of the time.  It's I/O is minimal.
    It basically just wants to have the resources to "think."
    
    We have an item called performance improvement on the wish list.
    THe main thrust of that improvement will be to make DOCUMENT
    think faster.
    
    Putting DOCUMENT at a lower priority by running it in a lower
    priority batch queue doesn't make it run any faster, but it does
    let the rest of the users run at the normal priority of 4 without
    too much interference.

831.6What to do with an APMYKENE::EXTONNow living with a SPYDER::Fri Aug 21 1987 08:178
    Re Document on dual processor machines.
    
    In some very rough monitoring I looked at of Document
    running on an 8300, I found that it performed almost
    ideally - using the attached processor most of the
    time. This was on V4.x of VMS.
    
    So you do not have to wait for V5 and SMP.
831.7MARTY::FRIEDMANFri Aug 21 1987 10:186
    I was under the impression that in order to wring the promised MIPS
    out of a dual processor machine you had to have synchnronous 
    multiprocessing. But it's good news if you can get significant 
    performance improvement even without SMP.

    A nit- SMP stands for SYMMETRIC MULTIPROCESS and not SYNCHRONOUS
    multiprocessing
