4026.0. "MCC_MAIN.EXE" by JUNG::GALVIN () Tue Nov 03 1992 20:40

    	MCC_MAIN.EXE installed image?
    
    Doing some performance analysis on this MCC Station, and came across an
    anomaly...  Is the MCC_MAIN.EXE image installed into memory? 
    /OPEN/HEAD/SHARED...???  Please tell me yes.  I looked in INSTALL and
    did not see it?  What file installs it into memory.  Did I miss
    something during the install?  Thanks.

4026.1MCC_MAIN is no installed:TEMTY::L_GROSSMANThu Nov 05 1992 12:546
MCC_MAIN.EXE is small and installing it into memory would only save a little
memory.  This code is basically startup code and would probably just get
swapped out over time.

What is the exact performance problem.

Hi there,
    Well you asked...
    
� What is the exact performance problem?
    
    
    	Basically, I'm trying to overcome my own stupidity...smile.  I
    *had* 5 domains setup for RECORDING of entities, I've grouped them by
    types of entities, ie:  DNA4_SYSTEMS, TERMINAL_patients, er SERVERS,
    etc.  I also setup 5 EXPORTER batch queues, using the same *logic*???
    	I've since spoken to one of the developers, thank you Sam...smile,
    and decided to consolidate ALL historical data into one domain!  I like
    it.  I'm in the process of propagating all the historian/recordings,
    and then I'll setup the exporter again...
    	I was seeing alot of PAGE FAULTING, via MONITOR SYSTEM; I was
    seeing close to 100% CPU utilization for looooooooong periods of time;
    and I was seeing alot of RWMBX processes, mostly the batch stuff, and
    the EXPORTER subprocesses...  From, SHOW SYSTEM, I saw alot of swapped
    out processes, mostly the UCX stuff, not doing much with my SNMP stuff,
    YET!
    	The configuration is EMS V2.2, with VMS 5.5-1.  Memory Managment is
    *actually* working like a charm.... trolling and tickin' away...smile. 
    I've since then added 6 100k pagefiles, set all volumes NO_HIGHWATER,
    installed MCC_MAIN.EXE, which I understand didn't buy me much, and said
    alot of HAIL MARYs....smile.
    	I finally got up the nerve to ask the customer to consider a, gulp,
    LARGER Server...smile.  We running on a VAX3400 with 36mg memory, and a
    Client of a DEC433 PC...  I've been receiving alot of hand holding, and
    great suggestions from the MCC team...!
    	If you've got more VMS tuning "magic", pray tell???

    Well, I think Dav Lyons had a few hints tucked away in the MCC-TOOLS
    conference.  You may want to poke around there and look for pointers to
    the "survival" kit.  I think there are some system tuning swags in
    there that may help.
4026.4Need a bigger CPUTOOK::R_SPENCENets don't fail me now...Tue Nov 17 1992 17:359
    You arn't gonna get much more out of a 3400. It is less than half of
    the speed of the minimum SPD system for what you are running.
    
    Six VUPs is the documented minimum for BMS V1.2 and by extension, EMS
    V2.2.
    
    Oh, and minimum systems give minimum performance :-)
