Here is a message from Lee Hirz, one of the former Mailman developers:
Mailman sends and receives messages locally in 2 ways. One method is to can send and receive messages as soon as the user hits the return on the SEND command. Because MailMan is configured to run according to a standard in VistA, this way is only available if a programmer goes into the code and makes a couple of changes, but it is the best way to run MailMan in a small hospital... because operations are much simpler.
I don't have the code in from of me, but you can recognize it because in order to "queue" messages for delivery by "filers" that are started by TaskMan, there has be be a record inserted into the queue. There is a transfer of control (GOTO) or a QUIT right after that, but below that, if the code hasn't changed a lot, will be the code that does the delivery and is even called by the filers. Basically, all that needs to be done is to remove the transfer of control and set a couple of variables.
The second method uses a background filer that must be started by TaskMan. In either case the Postmaster is just like any other user and can send and receive messages.
MailMan sends message across the network only using TaskMan tasks.

The submananagers are the proceses that actually do the work (the
thread pool, if you will). It Taskman goes long enough without any work
to do, th submanagers will shut down anyway. But the manager will
always start submanagers when they are needed. Off the top of my head,
I'm not sure if submanagers will still pick up tasks if Taskman is in a
wait state.
Does anyone know?

OK Nick,
When I use the menu system to call XUTM WAIT, it asks
if submanagers should be shut down (I answered NO).
It then says: Done. I then do option XUTM ZTMON, and
it does not show taskman in a wait state. Perhaps
because I didn't stop the submanagers...
Don't worry about answering this. All's well that
ends well.
Thanks

The output of D ^ZTMON will show the submanagers as
in
waiting state.

Nick,
I just played with putting my Taskman into and
then
back out of the wait state.
I couldn't immediately tell that it was in the
wait
state. How did you tell it was stuck in wait?
Thanks

Hi
Finally I found the culprit.
Actually the Taskman was in WAIT state. As soon
as
I
changed the state, all the messages reached
their
corresponding recipients.

My guess it that you didn't have any problems
only
because you put UCI in all
the places that needed UCI and VOL in all of
the
places that needed VOL. Had
you called whatever was in UCI in the VistA
you
started with, and VOL what
was in the VOL, you would have had to have
changed
it in fewer places. I
think the key is always with D GETENV^%ZOSV
and
then
setting all of the
parameters correctly with NO TYPOS and all
that
good
stuff the first time
around. At the risk of being a broken record,
that
happens to be broken in
the same place as Lloyd's record that broke
from
all
the times he used it to
tell me to do this ...
VISTA>D GETENV^%ZOSV
VISTA>W Y
Which give you in the output in the respective
places:
UCI^VOL^NODE^BOX:VOLUME
This is actually written right into VistA at
one
of
the ?? points, although I
don't recall which one.
Although I have not done configuration, I sure
have
had lots of chances to
help people with installations, and this is
where
all of the problems are.
Lloyd knows it so well, he can even tell by
the
error message where the typos
are. Now that is what I call "experienced"!

For what it is worth, it seems that most of
the
problems that I have hear people talk about

this
board in regards to taskman, is a problem
with
the
VOL,UCI etc. issue. Most recommend using
the
defaults
provided by the system, but it seems that
this
leads
poeple to problems. I cleared out all the
other
entries, and called my UCI "UCI", and called
my
VOL,
"VOL". It seems like I haven't had the
problems
that
others have...

Hi
The CPRS problem was due to the change in
file
access
rights. That has been solved. But the
"Waiting
for a

over
yet.

Nick,
Do you have a way to make your server
accessible
on
the internet for someone else to poke
around
on?
I'd be willing to look at it for a
couple
of
minutes
if you want to contact me off-board.
I'm self taught, so no promises as to
whether
or
not
I
can get you up.

Hi
I was able to overcome the previous
problem
with
the
command GO^XMKPLQ and GO^XMTDT, to
run
the "MOVER" and "TICKLER".
But still I was unable to send and
receive
messages.
So I just checked to see the tasks
running in TASKMAN, whose screen shot
I
am
giving
below :
510: ^LRCAPPH, COLLECT PHLEBOTOMY CAP
