Re: Contributing to, Building, and Maintaining VM370CE
#VMCE
Me too - I think it is very important for the people who love VM and Rexx but are not inclined to do peacemeal updates of these environments - due to lack of expercience or lack of time. We should try to move it forward and having 'nightlies' available to be able to test interactions of new levels of software are very important.
With the BREXX fixes and the work done on EE it is already a very representative and usable environment; I hope someone with the right skills and motivation can take over from Bob.
Looking at MVS TK5, it is very successful in that an update can be done which leaves intact the modifications one did to it (adding your own favourite historical userid et cetera) or choose a whole new distribution with the latest and greatest. I hope to see that also for VM/CE. A particular requirement would be to be able to painlessy connect to the new BITNET (HNET) - I know Bob left us a script for that, but personally I never got that to run; did some work with RSCS but apparently not enough.
Also, I absolutely love to be able to use and experiment with the old language tools - COBOL, FORTRAN, SNOBOL, ALGOL - would love to see the addition of SIMULA370 and some more. Be able to run BREXX is an absolute dream, and whatever we can do to connect that even more with CMS should be wonderful.
best regards,

It is not just XNET, it is the nature of the beast.?
When a CTC device has an i/o in progress, the entire channel
is busy; if there are other devices on the channel, whether they
are other CTCs or any other device, they will be unable to do
i/o or receive interruptions during the CTC i/o.
That is interesting.? I have never worked with a CTC at this
level.? Was unaware that is how the CTC works.? I would of course
expect the software to work that way.? As I said, though, I doubt
Hercules will ever have the channel appear busy.? Putting CTC's on
different channels might keep the software from getting confused
in some way.
Thanks for the insight!
?
So if you are using 500 for XNET, then I would recommend you
put RSCS's CTC on 600 or some other channel.? But if you are
aware of the possible reduction in throughput on a CTC channel,
then yes you could also put RSCS's CTC on channel 5.
?
The other thing is that our systems are small and generally
just single user, so the number of i/os issued by XNET across
the channel isn't going to be much of an impact.? XNET doesnt do
any "heartbeat" i/o, so if you are not doing anything at your
3270 terminal dialed to XNET, then there is no idle-time CTC
i/o.

How to setup DASDs sharing correctly between two z/VMs under Hercules.
Hello!
Sorry for my bad English.
I use one Hercules' instance for Share Device Server.
?
One Hercules' instance should use DASDs with read-write access, the second Hercules' instance should use DASDs with read-only access.
In Hercules' config for second Hercules' instance i define these DASDs as "READONLY FAKEWRITE".
In z/VM's SYSTEM CONFIG i deifne theseDASDs as "RDEV ... SHARED YES MDC OFF".
In z/VM's DIRECTORY minidisks on these DASDs are defined as "MDISK .... MWV ..."
?
Now I start Hercules' instances on the same PC under Windows 10, but in the future Hercules' instances should run on different servers under Linux.
?
These DASDs are used by the DBMS ADABAS. When I make changes in one Hercules instance, the changes are not displayed in another Hercules instance.
But if DASDs with changes are copied to another server where ADABAS is running, without closing the ADABAS nucleus, without rebooting Hercules or re-ipl z/VM, detach-attach DASDs, JUST COPY, then the changes will be visible immediately. ADABAS uses minidisks, but uses its own input/output.
?
§³an i set up DASDs sharing so that changes are visible immediately?
How do I set up shared access to DASDs correctly in my case?
?
Thanks in advance.

I have transferred the archive and looked at the list of files, but I do not have an empty minidisk at hands.

I am still busy with some nasty bugs in EE, which prevent a new bleeding edge release.
?
And you want instructions ... there is the question if to use the new help system or the small EE internal help.
Since EE can now run in high memory via RESLIB, the new help system can be called from within EE if EE is running in high memory.
?
EE now checks if it is running in the user area at 020000 ... and all CMS command restrictions are lifted if EE is running in high memory.

The channel does not actually exist in Hercules.? It started out
as an ESA/390 emulator so initially the channel subsystem was
implemented for subchannel I/O.? Later, support for S/370 was
added and the channel I/O commands were added as a wrapper to the
already existing channel subsystem.? The channel subsystem does
not report the channel busy.
There was an effort to emulate channels, but that did not make it
into Hercules.
So from Hercules stand point, it does not matter.
From the perspective of the guest operating system running in
Hercules, VM, it might care.
