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: I forgot the VOLSER of drives (3380) I created
Hello, I'm wondering there could be a bug-preventing VM from attaching these 3380 (380-38F, BGM380-BGM38F) via the SYSUSR macro? I can attach the drives manually (e.g., CP ATTACH 380 SYSTEM BGM380),

Hello, and thank you for your reply. What do people think of having VM support going down the list concerning IPL startup? By this, I mean that if WARM fails, failover to CKPT, etc., if allowed by the

Re: SYSIPL macro in DMKSYS
SYSIPL seems to be an addition to VM/370 by the Hercules community. The file SYSIPL MACRO is located on minidisk 094 of MAINT. I am sure some people in this group can tell you more about it. Cheers,

Re: I forgot the VOLSER of drives (3380) I created
One potential improvement to dasdinit I see is that it could check the filename extension of the dasd file. If it ends in .cckd, but no compression option is given, complain loudly. And the other case

Re: I forgot the VOLSER of drives (3380) I created
This is expected behaviour for dasdls as is. Your dasdinit command creates an emulated DASD with a VOL1 label containing the VOLSER you specified but no VTOC (address) yet, and that's what dasdls is

Re: Port of SQLITE ?
I'm playing with porting SQLite to VM/370 CE CMS. It may not be possible - I have to solve a few issues around truncating files and committing data to disk. Both of those are outside the normal realm
