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 :-

Harold, I think I turned attachments off. Just create a temp folder in the files section and upload, then only those who need it download it. Dave Sent: Wednesday, March 27, 2024 2:58 PM To:

Re: Virtual Machine Memory
Wondering if the proposed new command could actually be added at the CP level instead of the CMS/MVS level. CP might save the state of the machine to a prepared location in DASD then restore it when

Re: Virtual Machine Memory
Hello Harold, What you desire doesn't exist in VM/370 today, but it is possible. Cray Supercomputers are real memory systems that use swapping to allow multiple users to use the same real memory

Hello, You'll reconnect to the MVS console no matter the run setting. The run setting allows the virtual machine to continue running regardless of the state of the console. The default is RUN OFF,

Re: Reconnect to MVS Console
If you SET RUN ON, you shouldn't need to BEGIN when you reconnect. Cheers, Rene FERLAND, Montreal

Re: Reconnect to MVS Console
Hi Bertram: I have the machine IPL via the directory entry. I can confirm reconnecting even without the #CP SET RUN ON. Interestingly, if I do a #CP Q SET is shows RUN is OFF.

Re: Reconnect to MVS Console
Hello, To have MVS running upon reconnecting to the MVS console you need to set run on (#CP SET RUN ON) before disconnecting from the console. I'm not sure how you start MVS. I can think of two

If you enter #CP LOGOFF you logoff the MVS machine. You need #CP DISC to leave it running. To reconnect just logon to the ID you are using to run MVS. You usually then need to enter ¡°BEGIN¡±¡
