7323.0. "DWDOS : Unable to open fifth DECterm windows" by QCAV02::SANAND () Thu Feb 06 1997 03:52

Hi everybody,
    
Our of our customers has dwdos configured & running, however 
    they are facing the following problems :-

- customer is not able to open more than 4(four) Decterms

- Indiviually a single user can open - decterm,dxclock,dxtool,decterm
  one after the other but when he tries to open the 5th (fifth)
  window , he gets an error: UNABLE TO OPEN DISPLAY
 OR many a times pc will hang, one has to reboot or kill the process from
 server side.

- Memory is enough, Extended & Expanded memory is being utilized, not
  everything is loaded in conventional memory.

Setup is as under :-
    
Axp with OSF/1 V3.0, PWKS V5.0, PWKS CLIENT V5.1.
Digital Pcs(486) with dos 6.22, with 8mb/16mb RAM.
                         
    Can someone provide some clue/hints/pointers to resolve these issues.
    
    Thanks and regards,

7323.1MAX LINKS set too low?JAMIN::WASSERJohn A. WasserThu Feb 06 1997 14:1413

	At one time the default for number of simultaneous DECnet
	sessions was 8.  I think the command to check this is 

		NCP SHOW EXEC MAX LINKS.

	If it is set to 8 or some other low number, change it to 16, 
	20, 32 or some other suitably high number with the command

		NCP DEFINE EXEC MAX LINKS <n> 
7323.2--Using TCP/IP transport-TCP/IP Transport..QCAV02::KPREMMon Feb 10 1997 23:374
    We are not using DECnet. It is thru TCP/IP. 
    
    Any suggestions..

	There is some equivalent operation on PATHWORKS TCP/IP but
	I don't remember exactly what the operation is.  I think
	there was a file called PWTCP.INI that contained the
	settings.
7323.4if PW's TCP/IPVMSNET::S_VORESmile - Mickey&#039;s Watching!Wed Feb 12 1997 08:293
    pwtcp.ini's the file, tcpmaxsock is the parameter if I remember
    correctly. 
    
7323.5New problem emerged !!QCAV02::KPREMFri Feb 14 1997 05:1911
    I did try increasing the tcpmaxsock parameter and it worked fine.
    But a new problem cropped up now.
    
    While I open many sessions windows and If i do not run any application
    for a while, then the keyboard becomes inactive (not able to enter
    anything) and slowly one by one the sessions windows start
    disappearing. Strange isn't it !! See .0 for config details.
    
    What cld be the problem here. Unable to simulate this at the office.
    
    Tks for your earlier solution...
