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: VMUVM
It looks like my first step would be to make copies of my first level DASD and then rename the VOLSERs. Any suggestions on the simplest way to do this, perhaps outside of Hercules?

Re: VMUVM
My first rule for running VM under VM is that my Production System (first level) NEVER uses the same volsers as the Maintenance System (second level). This takes time to setup, but once it is done, I

Hi Daniel, Generally, its pretty easy to do and the effort is about the same as it is to get MVS to run under VM.? Basically, you need to: 1. have a second VM system with which to ipl as a guest of

The next exercise I'd like to try is to IPL VM under VM.? I'll surmise that I may need to duplicate some DASD and that some DASD can be shared read only.? Does anyone have a guide, or even a stream

Just a thought while I am at it... The "help" command in CMS currently only provides information about the Class G format commands.? While this may have made sense in a typical "real world" mainframe

When I perform a "q prt" command as MAINT or from the operator console I can see a number of spooled print files/jobs that came from MVS running under VM; for examples: OWNERID? FILE CLASS RECDS?

Thanks! I just tested it, and it certainly works (as this maclib layout is recognized by the assembler) but it seems rather incomplete compared to what I had. In all my enthousiasm I sent out a couple
