Subject: "Latch" style Batch Queue
Message-ID: <13j7bep5prb6bd6@corp.supernews.com>
Is there a way in VMS 8.3 to create a queue that when it is started, will
only process the jobs in the queue at the time it's started, but then hold
any additional jobs that are submitted until it starts again. Basically, I
need to create a queue that will accumulate jobs during the day and then
start after the system completes database cleanups at night and then
immediately stop.
Thanks,
Mike Ober.

Not quite what you need, but SET QUEUE/CLOSE and SET QUEUE/OPEN may be
of help, perhaps you can combine this with a generic queue.
If you can create a generic queue that points nowhere (or to a
permanently stopped queue), you could, at the time you need to process
jobs, use SET ENTRY/REQUEUE=newqueue. Any new jobs coming in after that
would stay on the generic queue until you next run that job to do the
requeue.
Another option is to stop/queue execution_queue and let the jobs
accumulate in a generic queue.
Then, when you need to do the processing, you count the jobs in the
generic queue, and then SET execution_queue/JOB_LIMIT=xx which means
that all the jobs in the generic queue get transfered to the execution
queue after which you can close the exec queue to force any new jobs to
remain in the generic queue.

DDS drives often can't read forwards, much less backwards! (Well, at
least the ones I've been using! They do seem to be working fine with
DDS-1 tapes but they are DDS-2 drives.)

Subject: UCX Ping on a DECWindows
Message-ID: <1194567355.107661.122530@t8g2000prg.googlegroups.com>
We recently migrated from a traditional DEC Vax box to a DecWindows.
We have lost our capability to use the UCX ping from within the
system.
I am an application support person and am having trouble effectively
conveying this point to the vendor support group.
Can you offer any help. I found information on the
http://www.uni-giessen.de/faq/archiv/vms-ucx-faq.part1/msg00000.html
site for UCX FAQ's it states
"This document contains "Frequently Asked Questions" (or FAQ for
short) about DEC TCP/IP Services for OpenVMS, also known as UCX, from
an earlier version."
It goes on to have a section about about installing a patch kit for
the DECWindows. We have been told that installing the patch is not
something we want to do. Is this correct? How do I recover the UCX
Ping capabilities
thanks
Teri

This does not adequately describe the old system, the new system,
what you did, or what happened when you did it.

Or to me. You might start by providing the output from
UCX SHOW VERSION
or
TCPIP SHOW VERSION
and continue with a session transcript which shows clearly what you did,
and what happened when you did it. Also, if it's not obvious, what you
expected to happen instead.
> Can you offer any help.
That's a question?

things to try:
$DIR SYS$SYSTEM:*PING*.EXE
If you have TCPIP Services installed (formerly called UCX), you should see:
Directory SYS$COMMON:[SYSEXE]
TCPIP$PING.EXE;1
If you have no *PING* in there, try DIR SYS$SYSTEM:TCPIP*.* or UCX*.*
Do you have any other TCPIP functionality on that system ?
With modern TCPIP implementations, to get command line capabilities, you
need to @SYS$MANAGER:TCPIP$DEFINE_COMMANDS
This will define plenty of symbols including "ping".
You could also do:
$MC TCPIP$PING www.apple.com and this would work without the "ping"
symbol.
