This group is for all folks running the original IBM VM/370 Release 6 operating system (or later (e.g. VMTCE (Community Edition)) on Hercules. Like the other early IBM operating systems this version has always been in the public domain and so can be freely distributed. The base version as supplied by IBM is lacking in many facilities. IBM solved this by providing additional extension products which were licensed and so are not available. There are however many user enhancements available which can be installed. In addition, in order to get users up and running quickly updated "releases" of VM/370 included the most popular updates are available for download, so novices can start to learn VM without having to delve into the system internals. It is intended that this wiki will provide information on the base release and these updates.
The available versions are here :-

Re: Would anyone like ....
My system did full backups of each minidisk on Sunday and then deltas for Monday through Saturday. We already had a mechanism to ask the Operators to mount a tape. I don't remember if there was any

Re: Would anyone like ....
I am sure there are many here that worked on many similar problems. A pity that Share wasn't as popular as GitHub seems to be and that everyone seemed more concerned about sharing IP.

Fascinating that I built much the same thing. To make it work also built a job scheduler and something to allow security to handle access, something to issue privileged commands etc etc. This started

Re: Would anyone like ....
Hi, The software included a very basic form of tape management. It would tell the operator to mount a new tape and how to label the one just taken down. The software would keep track of the contents

On Windows, in the installation folder of Hercules. Start a command window, and type the command at the prompt. If the folder is in your path, you should get the syntax of the command displayed. It

Re: Would anyone like ....
A tape management system might need to be written too. And maybe a data compression option? /Tom Kern

Re: Would anyone like ....
Hi, As it has been awhile and I'm new to VM/CE, one of the things I need to know is how much data can I get on a 6250 reel of tape? What other backup devices does VM/CE support beside a 6250 drive?

Re: DMKRIO and Herc
To my knowledge, there is no such thing as a 3350-1 and 3350-11 and you won't see any of these in DMKRIO. In the Hercules configuration file, you don't need to code the model (that is 11 or 1),

Re: Would anyone like ....
Hello Tom, You're correct. OCF used DDR for each drive so both used and free space was going to tape. Restores were equally messy and were at the mini-disk and not file level. My program was at the

Re: DMKRIO and Herc
3350 not 3330 model 11 an 1. I'll look at the file. How do you code the model number in the configuration file? Is that I'm the filee? Oct 23, 2022, 12:22 Ren¨¦ Ferland <ferland.rene@...> wrote:

To my knowledge, yes. 3330-1 has 404 cylinders, 3330-11 has 808 cylinders. Check the file DASD-SIZES.txt I just added in the Files section. Cheers, Rene FERLAND, Montreal
