Subject: Disk fragmentation
I have observed the disk fragmentation produced by XQP (VMS V4.3)
for some time and got the impression that it is unnecessarily high.
For instance the XQP appears to be distributing small files all
over the volume, splitting large free "extents" into ever smaller
fragments. I think that "extent caching" could be the culprit.
Question: Has anyone successfully "tuned" his system to minimize
disk fragmentation? Does it help to turn off extent caching?
Thanks in advance for any hints.

Subject: VAX PSI - PSIPAD
We would like to use a modified PSIPAD for the connection to another
computer system which has some ideas about terminal escape sequences,
but does not like DEC-Terminals.
Has anybody considered writing a program to make outgoing X.29 calls,
like PSIPAD, or has such a program available? How involved is it
to write such a program?
PSI documentation does not mention this topic, as far as I know.
Thanks in advance for any hints.

Re: Critical Regions under VMS
The worst problem with critical regions comes from the $DELPRC system
service which is NOT A PRIVILEGED request (the owner can $ STOP
a process from any other terminal).
With $DELPRC, NO exit handler is ever executed, so you can't rely
on an exit handler at all.
The 2nd solution given by Greg W. from DEC (raising priority to IPL$_ASTDEL)
is correct only if you need no cleanup later, so it does not satisfy
the original submitter's requirement. By the way, I might prefer
to put the critical region into a kernel AST instead of
raising the IPL, so I need not care for page faults.
For cleanup at image/process termination, however, only the "User rundown"
routine available for privileged shareable images is guaranteed to run
within process context (remember the V.3 "Real-Time User's Guide"?).
I think that such a "user written system service" is about the only
solution.
For a more elaborate scheme, I could imagine a separate process
monitoring access to the critical regions; this process could be
triggered after image/process rundown via the lock manager, and
do the cleanup required.

This is probably not new to you guys. For accounting reasons, I had to create an alias account on the VAX, and it shares the home directory with the 'real' account. Thus it shares the mailbox as well. When I read new mail now, the count of NEW mail messages is only adjusted for the account used for reading the mail. The alternate entry in the VMSMAIL.DAT file is not correctly updated. The fix is to issue READ/NEW to MAIL, and the new mail count will be corrected. Now some good stuff. Our site is developing a new VMS mailer. It will conform to the Interner Standards RFC822 (for message format) and RFC821/ BSMTP (for message transfer). The objective is a JNET bridge between DECnet and the Columbia Mailer. This is not yet available, and will not be in time for SF DECUS. Maybe in time for Nashville. However, if you want more information, please contact our postmaster, Reg Quinton. His address is <A362@UWOCC1.BITNET> (ie same as me - use A362 in place of A105). It is intended that this S/W will be publicly available when completed and stable. It will NOT be prematurely released. Hope this is of some interest to the readership of INFO-VAX.

We have recently installed 4 MicroVax IIs with one of them operating under VAX/VMS 4.4. All users get two default privileges, but they don't allow them to use Mail. The error message is as follows: MAIL-E-UAFOPNERR, error opening user authorization file -RMS-E-PRV, insufficient privilege or file protection violation. The only way to take care of this problem is if they are given Group privileges, but that allows them too much of an access that we don't want to give. Any suggestions on what could be wrong or how to fix this? Could be that the file that was tried to be opened isn't allowed to be opened by the group, or world. Our documentation isn't adequate enough yet, and doesn't tell what file Mail uses. Any ideas would be appreciated. Thanx in advance. Samir Kaleem..

The error message is as follows: > >MAIL-E-UAFOPNERR, error opening user authorization file >-RMS-E-PRV, insufficient privilege or file protection violation. > As a recall, the uaf file is protected (and with good reason) against any old user simply 'opening' it and reading it. Therefore, for running images that need to get information (such as mail and phone) one must either have some additional process privileges OR HAVE THE IMAGE INSTALLED WITH PRIVILEGES. I also seem to recall that the default startup procedures for a MVII DO NOT INSTALL MAIL OR PHONE, and therefore are totally useless to default priviliged users..... I have, after much munching and chewing of cud, come up with a useful series of systartup.com and related procedures to install known images, set up system logicals, etc.... I would be happy to send the to you is you wish, and to anyone else with any desire for them. -ed cetron center for engineering design univ of utah

RE: DV11 on VAXen, or equivalents
Is there anybody using DV11s on VAXen? The DV11 was/is a 16-line
DMA multiplexer on the UNIBUS supporting BSC-like protocols.
Not too long ago, I noticed that some company (Able?) offered a
DV11-lookalike. Any experiences?
If the DV11 appears to be out-of-date, how would you connect
some 30 lines running a BSC-like (private) protocol to VAXen?
Any hints & opinions are welcome.

HELP! please remove MPC91B@DGOGWD01.BITNET from your mailing list. Since we're receiving mail by a dialup line, a single copy is enough (I can distribute it locally). I tried "info-vax-request" two weeks ago, but nothing happened. What is the correct way to cancel a subscription?????? W.J.Moeller, GWDG, Goettingen, F.R.Germany

RE - Connection to IBM's RSCS
We are looking for a (cheap) connection from our VAX 8600 to a (new)
IBM mainframe. Supposedly there exists software from Argonne National
Laboratory (ANL) for connection to RSCS.
Could please somebody point me to the source of this software, or give
a short account of its functionality.
Thank in advance,

Now that the various "flames" over VMS mail have quietened down, may I
suggest a simple way to handle the digests. All you have to do is to
do FORWARD/EDIT to yourself ! Once you are in the editor (mines EVE),
you can extract the mail messages you need. Of course if you quit from
the editor no message is sent.
