protect.
Nowadays you might need that.

It is used for MVS and VSE guests that are looking for job "start" and "end"
tags (e.g. // JOB or /*), enabling multiple jobs to be stacked in the hopper.
CONT suppresses EOF until all eligible spool files are consumed.

When files arrive an action routine can be triggered to process the incoming
files. We've used it to transform SYSPRINT files from z/OS and convert them to
PDFs and archive them. The reverse is also true: you can submit jobs to z/OS,
z/VSE, or even CMSBATCH.

Would a NJE deployment on/with Linux — Sine Nomine's NJE/IP as a notable
example — be relevant here?

Thank you Mark.
VM CP presents the interrupt to Linux, why should Linux then ignore it?
I’m not a kernel internals guy but my view is Linux should propagate any
unsolicited interrupt like this so an application can have the opportunity
to act on it.

Greetings Beloved Mainframers,
Could I suggest "netcat" ?

It is well thought out.

The first place to start for Linux documentation is in the distro-specific
Device Driver, Feature, and Command Reference. You will find there an example
of using an SMSG to run a vmur command, along with the discussions about
security.

Thanks Jeffery. Yes that would work but I’m trying to avoid polling loops,
or a cron thing that checks every minute or so.

If you don't mind polling or there being a delay then you could run a script
like this:
# Poll every 30 seconds
RDRS=`vmur list | grep `
while [ -z "${RDRS}" ]
do
sleep 30s
RDRS=`vmur list | grep `
done
RDR=($RDRS)
# ${RDR[n]} contains the results - you could then extract ids
from perfsvm and log them

Subject: Re: Can zLinux detect when files arrive
I don't think Linux itself can detect that. But if you monitor the Linux
console through a user running PROP you can see a file has arrived in
the RDR because this will give a message in the virtual machine. PROP
can then be used to send a command to the Linux machine to process that
file.
Could you use the vm command interface to issue an Q F every x seconds.

FILES: 109 RDR, 028 PRT, NO PUN
If there are files in the RDR, time to go to work. Not as nice a catching
the DE but should work.

Jeff
When a traditional channel-attached device transitions from not-ready to ready,
an unsolicited DEVICE END I/O interrupt is raised. (UE indicates EOF on the
reader.) Similar for tape and 3270s.
But I don't think Linux generates a UDEV event for unsolicited DE.

Alan
