Re: How to save CMS system?
The SAVESYS command *MUST* be *ONLY* entered at the 1st VM READ after the IPL command. If you wait until after the 1st ready message, then it won't work.
?
The problem is that DMSINS has some additional initialization to do after IPLing the saved system and if you enter the SAVESYS command after the ready message, that reinit work doesn't get done. One of the really important things that happen in DMSINS after ipling a saved system is to initialize all memory controls based on the memory size of the VM doing the IPL.
?

Re: How to save CMS system?
From what I understand, when you want to move a program to minidisk > MNT19E 19E Y/S to make it available to all other users, you have to > (re)save the CMS system. A useful way to avoid having to resave CMS all the time is to have an additional program disk to hold locally installed stuff that's not part of the base CMS installation. We used a minidisk that was owned by MAINT, and ensured that it was accessed by all users as 'P'. An additional handy thing to know is that RENAME is atomic, so you can add files to the P disk, or _update_ them there, with impunity, if you do it right: - Link the P disk M as some additional mode other than P. - COPY the new or updated file there with a temp name. - RENAME the old file (if any) to e.g. a versioned oldname. - RENAME the new or updated file to the intended name. - RELEASE the disk. - Have all logged in users reACCESS P. Until they reaccess, they will get the old version of an updated file. If you use MR mode for the link, you may get an R link if someone else has an M (or W, naughty) link, which is why I suggest M mode. (We had a script for this, so it was desirable to avoid the issue rather than to try to detect it and clean it up.) De

Re: How to save CMS system?
Well it needs to mode 2 so the copy has to be = = z2...
.. I then think you need "access (noprof" after the IPL and before the savesyd but on my phone so can't check manuals

Yes.? The SYSBPROF EXEC on the S-disk uses it to load the C library into memory if it can't be loaded as a shared segment.

Hanushevsky and the rest of the Cornell VMers shared a lot of useful code in the 70s and 80s.

The whole story:
I watched Prof. Ferland's video, with difficulty because I'm better at reading than watching a movie.
My goal was to define three lines, one towards TK4-, the second towards HMVS (Jay Moseley's system) and the last one for an RJE station.
So I started looking in the documentation and I saw in the sysgen manual that normally in the first phases of the IPL it asked for the time and type of start. Something I had never seen with the VM/370 CE.
As I said, I couldn't find a refernce in the online manuals and I had to ask.
I always use SHUTDOWN and every reboot of VM was automatically done without any request.
