DECnet performance problems (on TOPS-10)

by gerry77＠mail.com

Dear All, I'm in need of some suggestions to improve DECnet performance of a TOPS-10 monitor running on KLH10. I'd like a lot to hear from you even if you do not know or run that specific system or configuration. When used locally at the CTY (Console terminal), the system response is very fast and smooth, so I'd tend to exclude emulator problems and such. Instead, when used from a remotely connected terminal (e.g. from VMS via SET HOST), it appears very sluggish: single character echo is very poor and output from the system fits and starts all the time. Output from programs is very fast for some hundreds lines, then stops briefly, then again appears almost instantly, and so on, like in bursts. Anyway, while the overall bulk data performance can be considered absolutely acceptable, the char-by-char responsiveness, e.g. typing interactive commands at the monitor prompt, is horrible: I type "D", "I", "R", and nothing happens, then I type "E" and "DIRE" suddenly appears... The TOPS-10 system has plenty of free core (both virtual and physical), free disk space, and free CPU, so it shouldn't be an OS issue in itself. Probably the most likely cause of this problem lies in some DECnet parameter that needs some tweaking, but I do not know which one... Have you ever had any experience with some ancient Digital OS having poor DECnet performance as described? And how did you solve that, or at least improve it? Here are some (maybe) interesting bits: Request # 1; Show Executor Node Characteristics Completed Executor Node = 1.1010 (DIECI) Identification = DECnet-10 Version 4.0 Management Version = 4.0.0 Loop Count = 1 Loop Length = 127 Loop With = Mixed Incoming Timer = 30 Outgoing Timer = 60 NSP Version = 4.0.0 Maximum Links = 65535 Delay Factor = 48 Delay Weight = 10 Inactivity Timer = 120 Retransmit Factor = 10 Routing Version = 2.0.0 Type = Nonrouting IV Routing Timer = 600 Broadcast Routing Timer = 40 Maximum Address = 1023 Maximum Circuits = 20 Maximum Cost = 100 Maximum Hops = 16 Maximum Visits = 20 Maximum Broadcast Nonrouters = 64 Maximum Broadcast Routers = 32 Maximum Buffers = 80 Buffer Size = 576 Segment Buffer Size = 576 Request # 5; Show Line Characteristics Completed Line = ETH-0 Receive Buffers = 6 Controller = Normal Protocol = Ethernet Hardware Address = AA 00 04 00 F2 07 Receive buffer size = 576 Request # 7; Show Circuit Characteristics Completed Circuit = ETH-0 Cost = 1 Maximum Routers = 16 Router Priority = 5 Hello Timer = 90 Type = Ethernet I'll be grateful for any suggestion! :) G.

Anyone with a spare MMJ cable + RS232 adapter?

Are 3 wire sufficient? Most of the ones I make, I only end up doing RX, TX, and GND, but I can do the handshaking lines if you want. The cable I have most of is 6 wire, but it's solid conductor, like telephone wire. Works well enough for these speeds/installations, though. To be clear, let's agree on the cable specs: MMJ - MMJ RX, TX, GND 6' (2m) long enough? Qty 4 As for $$, I find your suggestion ambiguous. (If you sent me 5Eu and told me to spend it on a 30Eu bottle of wine, it would fit.) So how about $25 Canadian + postage? Before we get too excited, I'd better locate the connectors. Will confirm. Cheers, Phil

My server is not apparently getting along with the HECnet list. I have a couple of dozen MMJ connectors in the shop, I believe. I could send you some, or we can talk about making up a cable. (I'd rather not be without my MMJ crimping tool.) Best, Phil

Noob question: Changing the Time Zone on my VMS boxes?

Yes, There is a script given: $ SYNCH_CLOCKS: $ RUN SYS$SYSTEM:SYSMAN $ SET ENVIRONMENT/CLUSTER $ CONFIGURATION SET TIME $ EXIT $ WAIT 6:00:00 $ GOTO SYNCH_CLOCKS Seems like a sensible thing to do in a clustered environment. Regards, Mark.

VMS Bound Volume Sets...

by hvlems＠zonnet.nl

Bind sets are hell to restore. Which is probably why Hoff is against them. A RAID controller is a good idea: form shadow sets and stripe them. The Mylex 960 series can handdle RAID volumes up to 36 GB (IIRC). So you'd need another controller. Not all controllers are supported b VMS, e.g.: kZPCC. ------Origineel bericht------ Van: MG Afzender: owner-hecnet at Update.UU.SE Aan: hecnet at Update.UU.SE Beantwoorden: hecnet at Update.UU.SE Onderwerp: Re: [HECnet] VMS Bound Volume Sets...

(If it is an AlphaServer or Integrity system of course, in this case.) I use an SA6400 successfully to do that, in one of my rx2600s. - MG Verzonden vanaf mijn draadloze BlackBerry -toestel
