You may solving the wrong problem. :-)

Maybe? At the moment, I mostly care about me not needing to to housekeeping. What are computers actually for, if not for automating boring and repetitive tasks? :-)

It takes the raw monolithic JES2 output and splits the SYSOUT by JOB/TSU/STC. Thus you don't have to purge all or nothing.

Thanks for the hint. Maybe in a later point in time, I'll reconsider my approach, especially when considering printing reports to PDF. First, I want to get accustomed to JCL, to VSAM, and then to COBOL with KICKS4TSO. (I'm already having great fun with my old AS/400 writing small applications for housekeeping with just a few database files.)

Right now, I'm just not doing enough serious stuff with the machine. ATM, I'm just fine with another shell window, 132 chars wide and a tail -f on prt00e running inside.

find /my/print/directory -type f -name '*.txt' -atime +5 -ls -delete
Note that NO commands need to be issued to Hercules (and you don't wipe out everything at once.)

Thanks, I noticed. Just a hint (and not meant as being cocky): I'm using Linux since 1995, and I'm a Linux System Administrator since around 1997. I'm just new to MVS.

On an actually used (TK4-) system, printer output files tend to get large over time. So I want to truncate them to zero. I'm running 4.3.9999.0-SDL-g9ceed2cc on Linux.

What is the recommended way to do this without stopping and restarting hercules? Usually, a program has to be forced to close and reopen a file, so the actual blocks on disk are freed.

You may solving the wrong problem.? :-)

This doesn't do your clean up, but may help:

Once running this, you might run a command via CRON to kill listings older than N days, for example:

	find /my/print/directory -type f -name '*.txt' -atime +5 -ls -delete 

Note that NO commands need to be issued to Hercules (and you don't wipe out everything at once.)

There is a thread here referring to a hercctl utility to allow you to shoot commands at a running Hercules instance, but the link in it is stale, and I can't find it anywhere else.

Thanks for the hint to local http server! I completely forgot about that one. (I found a reference that it's just a shell script, so I don't need that anyway.)

I'll let logrotate do the housekeeping:

[/etc/logrotate.d/hercules-mvs]:
---8<---
/opt/mvsrun/prt/prt002.txt
/opt/mvsrun/prt/prt00e.txt
/opt/mvsrun/prt/prt00f.txt

}

for DEV in 002 00e 00f; do
curl -d "command=devinit+${DEV}" -X POST
done

write a shell script to scratch the file and shoot the devinit command at Hercules via HTTP:? (probably using curl). schedule it in cron.

There is a thread referring to a hercctl utility to allow you to shoot commands at a running Hercules instance, but the link in it is stale, and I can't find it anywhere else.

This worked for me, no way to see what the response is.

curl -d "command=ipl+148" -X POST http://localhost:8081/cgi-bin/tasks/syslog

You may want to consider having it name your printer files yyyymmdd, then you can keep a few days worth around, and clean them up with a find command.

Spitballin' here, but something like:

#!/bin/bash
ymd=`date +"%Y%m%D"`
curl -d "command=devinit+10d+$ymd.txt" -X POST http://localhost:8081/cgi-bin/tasks/syslog

Thanks!

I think, deleting the old file, and then just doing a devinit should close the file and create a new one.

Yap, works! Thanks!

Can/should I just delete the old version from SYS2.LINKLIB?

Sure, why not?

The later version has support for processing segment overlay programs.

Cheers,

I was looking at the versions of software on my MVS38J builds, and noticed that I have 2 different versions of REVLMOD.

Hi Mark,

Can you point me to some documentation for interconnecting 2 MVS guests using CTCs and VTAM?? I've got the CTCs genned in MVS, but haven't found any documentation yet on how to take advantage of them.? I'd prefer to work outside of VM, but I'll start there to get it working and then move it outside if I have to.

Thanks,
Jeff

Mark is right.? When LPARs first came out every once and awhile you would get some VM errors messages as it crashed. It was originally just a VM system with the covers closed so that you didn't have to "learn" VM and could not run applications on it.

Creating paging volumes at the guest or host level?

Rahim,

If you load and run VM/370 as the primary OS, then you can run multiple operating systems under it, each in their own "virtual machine."? You could run DOS/360, DOS/VS, OS/360 (MFT or MVT, your choice), or OS/VS1 or MVS 3.8J ...

And of course you can also have multiple users signed on to VM running CMS... all at the same time.

Where do you think "LPARs" came from originally?? :-)

Hope that helps,

Mark S. Waterbury

The JCL listed in the manual has 2 errors in it.? For the "IN" dd, delete one of the DISP= keywords.? For the "COPY" statement, delete the space after the comma.
