1097.0. "Connection problems" by BEING::JONES () Wed Jul 12 1989 11:06

I got the VMS doc. set CD the other day and set up my MicroVAX II system
to be a "server" for our group to use it remotely via the Bookreader.

I set up a captive account on the uVAX that runs a command file that
finds out what the remote node is then does a SET DISPLAY/CREATE/NODE=
command then runs the Bookreader.  Once done the command file does
a SET DISPLAY/NOPERM then logs out.  I set a limit of 10 users at
any given time that can have access to the account.  Now people are
using it and get the following when they reading the doc. set:

The uVAX II is running VMS V5.1.

XIO: non-translatable vms error code: 0x2DBA002, vms message:
%decw-e-cnxabort, connection aborted
%XLIB-F-IOERROR, xlib io error
  READ$VMS     logged out at 12-JUL-1989 09:05:08.68
%REM-S-END, control returned to node _RUN26::

Can anybody tell me what is going on, and can it be fixed?

1097.1	I believe there is an easier way	AGBEAR::HORNER	A.G.Bear, Low tech teddy bear	`Wed Jul 12 1989 13:45`	13
	I suspect that you would be better off to serve the CD reader if you are part of a cluster, or use DFS if not part of a cluster. We have the CD reader on a MVII and serve it to a MIVC cluster. We then define the DECW$BOOK logical as a search list containing first the RA disk directory where some books are stored, followed by the CD reader specification. This way you avoid all of the extra process overhead, and people can run their bookreader any way they like and access books both on and off the CD from the same local workstation bookreader process. You can then edit the LIBRARY.DECW$BOOKSHELF file to contain all of the bookshelves, and bookreader does the rest. Dave
1097.2	Not all are in a cluster	BEING::JONES		`Wed Jul 12 1989 14:53`	12
	Dave, I'm part of this cluster so I have no problems, but not everyone in the group is part of the uVAX II cluster that has the CD reader on. That is way people have to set host into the uVAX and run book reader over the net to there local workstation. So what is DFS? Where can I get it and how do I use it? - Rick -
1097.3	Number of users supportable?	STAR::ROBERT		`Wed Jul 12 1989 16:57`	11
	We would appreciate anecdotal evidence about how well the CD performs with information about multiple users. We constantly get asked this by customers but don't have a lot of hard numbers. We have a few examples that suggest one reader can serve a pretty good number of users (but it obviously depends on how many are actively doing disc IO which can vary a lot moment to moment and group to group). We're specifically interested in CD performance ... not mag disk. - greg
1097.4		GVRIEL::SCHOELLER	Who's on first?	`Wed Jul 12 1989 18:21`	16
	Rick, DFS stands for Distributed File System. It allows you to mount disks on another machine as though they were local. It uses DECnet to perform the data transfer. Its performance is supposed to be very similar to LAVC. DFS is a product that can be obtained through normal channels or off of the net. You will need to make arrangements with the DNS (Distributed Name Service) people for access to a directory in the name space for your DFS access points. The person to contact is Connie DISSRV::Sandstrom. We are currently using DFS to serve the DECwindows Online Documentation from my VAXstation II/GPX to about 10 other people in our area with no noticable performance problems. Dick
