2959.0. "set display/create/node=mynode limits?" by RABBET::FARRELL (Money, there is no substitute!) Tue Jun 19 1990 23:42

Hello,

I have a problem which looks like a boundary condition.

I have 4 different systems setting display back to my workstation.
This works fine.  I then try to add a fifth system to set display and the
display fails.  I have mixed-and-matched the systems, and it does not matter
which one is the fifth system.

I am using DECNET as a transport, and these systems are not clustered.

So my questions are ...

	1) Is there such a boundary?
	2) If so, is it configurable?
	3) If not, any/all suggestions would be appreciated.

2959.1Server connection limitSTAR::VATNEPeter Vatne, VMS DevelopmentWed Jun 20 1990 15:467
The server for VMS V5.1 through V5.4 is limited to 32 connections.  This
includes the session manager and the window manager.  The DECterm controller
only counts as a single connection, no matter how many terminals it controls.
The limit is hard-coded.

You should definitely get more than 4 connections to your workstation.
What does SYS$MANAGER:DECW$SERVER_0_ERROR.LOG say?
2959.2Bump up ENQUEUE limitGSRC::WESTHelp stamp out and abolish redundancy !Thu Jun 21 1990 11:5212
  Increase the ENQUEUE limit of the server process.

  DEFINE/SYS/EXEC DECW$SERVER_ENQUEUE_LIMIT 300

  The default value of 64 is not enough sometimes.  I noticed the same
problem on our VS3520's.  We were only getting about 9 to sometimes 15
connections.  I increased this value and have been able to get all 32
of them.

This problem only applies to local connections, not to DECnet connections.
There was a limit of 15 local connections in VMS V5.1 through V5.3, due
to a too small enqueue limit.  This limit was raised to 64 in VMS V5.3-1.

If 64 is not enough to get all 32 local connections, please QAR it!  We
have not heard any problems with this up until now.

  Yes, we are using local connections.  Thanx for pointing out that this
is all it affects.  We only modified the enqueue limit based on a hint
from the CSC sometime ago.

  Ok...
