Tim, There is no way for a user to allocate a tape as via JCL on MVS. Typically, sites used to use the MSG command to ask the operator who would:- ? 1. Mount the tape = Hercules devinit command 2. Attach it to the requesting user, e.g. ¡°ATT 580 CMSUSER 181¡± 3. Send a message back to say its done¡ ¡°MSG CMSUSER YOUR TAPE IS READY¡± ? Of course as you are both user and operator you can just mount the tape and attach it to your user-id.? You can unmount a tape attached to your user by ¡°TAPE RUN¡± You can then use the Hercules console to mount another tape, or do ¡°DET 181¡± to give the drive back to the system ? Dave ? ?

You press whatever it mapped to "PA2". Often "Page Down" but can be Alt+F2 or others How did I create minidisk? How do I add user accounts? You edit the user directory, and put it online with the DIRECT command but its non-trivial and requires knowledge of disk cylinder usage so I suggest using the CMSUSER account. It has multiple large mini disks. Not the sort of thing we would put in an introductory manual. Later systems usually have a tool called DIRMAINT but we don't have anything like this.
I did learned how to use ACCESS and XLIST with HELP facility command.
I think that they need to provide getting started guide manual comes with
VM370 CE package. Also, I can't find any "getting started" manuals on
VM370.org, etc.
Its on my to-do list but at 69 years old not sure it will be finished before my time here ends... ... for most general user tasks we expect the help to suffice. After all when delivered VM/370 had no help.
Look at MVS TK4- package comes with getting started manual.
It does but we are not MVSers. As a VMer I always refer to MVS as "Man Versus System" ..

Re: Doubts about setting up RSCS

Hi folks.
I'm trying to get RSCS up and running between some VM370CE instances, in order to learn and understand as much as I can about it.
So, I've read the RSCS MEMO very carefully, but, due to my lack of experience, I fail to have a clear picture about how all the pieces and procedures fall into place here.
I've also gathered and read some other older posts and miscellaneous pieces of info around, but the problem I face is that I have the feeling that that info is either too old, comparing with what alreadi is at current VM370 CE, or seems to be somehow too new (IBM sites)... all put together, I'm quite confused, hope you could put some light here. i'll try to summarize my initial doubts.?
- SYSTEM NETID
Because my tendency to recall on what I know (Linux networking), even before starting to deal with RSCS itself, I quickly stumbled with the SYSTEM NETID issue ... I feel that, much as I have to set hostname and hosts file on Linux, so I should do on VM370 for RSCS...but I find no clue about that really. The RSCS memo I read (I read there're different versions) mentions nothing about it... so
Has to be set up? or is just a recommendation? What is the procedure to do so? ... I expect some kind of fancy reassemble/compile procedure to be needed, but I don't find anything specific on the matter.
And what about the Hercules side? Should I tweak the CPU serial number to match the config file? that would make sense but I'm not sure about anything.
- RSCS, RSCS1, RSCSTST
Sure, there's a good reason 3 User/VMs are there instead of just RSCS... but I don't find which one should i use, or why.
I Find the idea of the disk arrangement explained on the MEMO a very clever one, but I keep confused on which one shoul I use.
Reading about NETID file, I read that different CPU/LPAR/NodeIds can be mapped to different NetIDs.. but I don't put the pieces toghether... maybe this is a way to have two (or many) parallel networks of setups on a same machine (for instance, a local net, and a separate Internet one) but everythin just speculation on my mind.
- RSCS MEMO
Although it reminds somehow to what I learn while messing with DMKRIO or VRTREAL, so it's nothing scary at first glance anymore, I still fail to put the pieces together when it comes to why are there two separate procedures.
While the initial procedure is quite clear to me (Update COPY files at A, then VMFMAC and VMFASM procedures), the second one is quite confusing.
Considering that there is, in fact, an already present configuration in place, I'm not even sure whether I shoud go directly to the second procedure of the MEMO: Update an already present setup.
But I have the feeling that, much as what happened with DMKRIO and the MAINT MEMO, maybe there's a more straightforward way to mess with this (being the instructions on the MEMO somehow more academic, geared towards distro maintainers)... how do you approach this?
Thank you very much in advance.

Re: Wakeup userid - what is it?
The WAKEUP server on VMCE is used to automate various operations on the VMCE system. An example would be cleaning up console logs from various system processing.
The timer code was originally written as a REXX function package for VM/SP by developers at SAS Institute in the early 1980s.? I don't know if any of the code made it into the IBM WAKEUP command.?
The server code to schedule events and define what actions to execute is in REXX on the WAKEUP server machine. The code to process timer and SMSG events is in assembler in source code DMSLFN (plus update files) in the VMSETUP CMS search order.
I modified the SAS code for VMCE by changing SMSG command input processing to VMCF instead of IUCV,? removing CONSOLE macro use, and other code changes to run on VM/370 rather than VM/SP.

VM/CE has a disconnected service machine, directory entry WAKEUP, that runs the wakeup module.

Re: Updating DMKRIO on VM370 CE
#VMCE
Hi Alejandro,
Separating your own changes from IBM changes is probably the main point of documents like "What Mother Never Told You About VM Service." I believe you are better off NEVER modifying anything on your system? distribution disks. Using local disks to hold any system file changes you make, make it MUCH easier to re-apply those changes to subsequent releases of VM.
Bob Bolch
Wow!... definitely i have to test that!
The thing is that I'm staring to understand (thanks to an user that promptly provided me with help) the logic on the 'layered' approach/procedure behind MAINT MEMO,? and looks to me a very clever way to implement a kind of 'version control' for maintainig the distribution changes... however, those reads now make me wonder why you just can do that.
I mean, the way you say, it seems pretty straightforward (and I like it! :-D) ... no DMKRIO AUXLCL, no DMKRIO LCLxxxDK, etc, etc .... you just invoke VMFASM? ?along with DMKRIO DMKLCL (which I guess could be enough to deduce it is a Local change on CP's DMKRIO) and you're ready to rebuild CP?

Re: Updating DMKRIO on VM370 CE

Hi!
I sense you are wanting to run an RJE Node in VM/370 CE and communicate with RJE in MVS/370 (tk4-). ?Is that close?
Well, communications and networking are definitely of my interest... and while the RJE/JES2 feature you mention falls as part of the exercice, it is not the end goal (I don't know about RJE... I'm just too new to all this) but rather a part of it. My goal could be, for instance, to be able to bind x3270 to a TCP port where a 3335 TTY session is presented by tk4- running as a guest atop VM370 (just an example, it could be SNA VTAM 3270, SNA TCAM 3270, etc...) Obviously, the key for that to happen is to be able to DEDICATE/'passthrough' the involved emulated devices/CUUs, up to MVS User, at the right Virtual CUUs, to let Tk4- to handle them. Basically, after checking on IBM sysgen book and finding that 3705 and 2703 were mentioned as supported by VM30 DMKRIO stuff, I felt this is the perfect exercice to go 'dirty hands' and mess around with VM370 and learn a lot. Cheers.? ?

Re: Updating DMKRIO on VM370 CE

I think that it is clearer to put ALL CP user modifications on the local?disk (MAINT 594) and all CMS modifications on the CMS changes disk (MAINT 593). MAINT 594 for CP changes. MAINT 593 for CMS changes
Keeping installation?specific changes separate, I suggest the following method for your changes to DMKRIO?ASSEMBLE:
1. VMSETUP?CP? 2.COPY DMKRIO?ASSEMBLE F = = A 3. Make the changes to DMKRIO?ASSEMBLE A that you want. 4. VMFASM DMKRIO DMKLCL 5. Use VMFLOAD to create a new CP Nucleus as documented. 6. VMFLOAD CPLOAD DMKLCL 7. IPL 00C CLEAR to load the new CP Nucleus as documented. 8 . When testing is complete, COPY: ? ? DMKRIO ASSEMBLE A and?? ? ? DMKRIO?TXTLCL A to the 594 (E) disk, ? ? Then ERASE the copies on the A disk.?
Later on, if you have MORE changes to DMKRIO: ? ? VMSETUP?CP ? ? Copy DMKRIO ASSEMBLE E = = A ? ? Edit changes into your local?DMKRIO?file. ? ? VMFASM DMKRIO DMKLCL ? ? Then follow from step 5 above.
