Re: How do I report a bug in VMCE?

 

Hello,

The problem occurs after I IPL CMS.

The steps are:

1) IPL CMS (e.g., /cp I cms)
2) At the prompt I do a /cp disc
3) After the PROFILE EXEC runs the user disc from the Hercules 3215 console.
4) I log OPERATOR into a 3270 session.
5) Then I do a #cp define storage 3M (to 15M)
6) I see the messages:
?Storage = (set about in K)

The disabled PSW message does not appear.

I do?

1)CP I CMS and nothing occurs.
2) cp m * hi and in the lower right hand it says "not accepted"

If I do #cp things work.

Bertram Moshier?

Well OPERATOR is a funny beast. Many things behave differently, or usually behave differently. Its generally the first logged on user so it receives certain messages which can interfere with other thing.

It has ¡°TERM MODE CP¡± set by default so commands are passed to CP not another user.

I think that is why you get the odd behaviour with ¡°def stor¡± which will always cause a reset so you always need to re-ipl cms.

If there is no OS loaded the default on OPERATOR you won¡¯t get a message about a disabled wait because your VM is already in that state.

Is that your only issue?

I am not sure if it should. I¡¯ll check on the base software.
FWIW, it appears that with z/VM, it doesn't load a disabled wait PSW after redefining storage either. Instead, it simply resets the system and clears storage ("Storage cleared - system reset"), leaving the user in CP mode, thereby requiring you to ipl cms again if you want to be able to issue CMS commands.

And if your run mode is set to run ("q set" shows "RUN ON", which is usually the case for the OPERATOR userid as I recall), there's no indication that you're actually in CP mode after the system has been reset either. Instead, "RUNNING" still appears in your status area, even though you are actually in CP mode.

On a regular user with a normal run mode of off ("q set" shows "RUN OFF"), whenever you redefine storage (and get the normal "Storage cleared - system reset" response), your status changes to "CP READ", letting you know that you have to reipl cms if desired.

I'm sure VM/370 behaves the same way in this regard, although I admit to not having bothered to check.

Re: "Waterloo Tapes" in H390-VM group's Files area

 

¿ªÔÆÌåÓý

Mark,

OK so we don¡¯t have the source to PETAPE only the mods that were made to DMSTAP. Not sure which of those tapes they are on, but I think they are there.

Not sure at what point VMFPLC2 appeared, but it is supposed to produce consistent tapes regardless of release. Not sure it does, but that¡¯s one reason for using it.

Simplest way to read the early tapes is to patch CMS to return 0 when the read length is short. So the relevant code in DMSTIO is ¡­

?

000230 41F0 0008????? 00008???????? 390 INCLEN?? LA??? R15,8????????? INCORRECT LENGTH ERROR?????????? @VA03457 00309100

000234 07FE???????????????????????? 391????????? BR??? R14???????????????????????????????????????????? @VA03457 00309200

?

On my VM/CE DMSTIO loads at F8F9A8 (from the CMS NUCLEUS MAP)

?

So INCLEN will be at F8FBD8 in our CMS machine and we can check

?

d f8fbd8.10?????????????????????????????????????????????

F8FBD8??? 41F00008? 07FE000D? D9C5C1C4? 40404040

?

So if we patch that

?

store f8fbd8 41f00000

SHARED SYSTEM CMS????? REPLACED WITH NON-SHARED COPY????

STORE COMPLETE???

?

So PETAPE should now work, and the one from the R5 tape appears to be fine. I have appended a full console session showing before and after the patch.

Hi, Dave,

I saw that link to the VMSHARE stuff about those problems with PETAPE on newer VM versions -- a very good find!??

Do we have source code for PETAPE?

IIRC, when PETAPE first appeared, it was done as an UPDATE deck for DMSTAP -- the CMS-supplied TAPE command.

Perhaps this also explains why the VM SHARE project just switched over to using VMFPLC2 instead of PETAPE?

Re: q stor response on an unmodified VM/370r6 setup

 

When on MAINT remember its has all classes assigned, so on MAINT "Q STOR" behaves differently to other users....
.. if you do "Q STORE" you get the real system storage, if you do "Q V STORE" you get your virtual machines virtual memory size.
This can be larger or smaller than the real storage size.

I found the following reference to PETAPE's challenges due to IBM changes to CMS TAPE command.



Append on 06/27/90 at 09:49 by Stuart McRae of Systems and Telecoms:

And as for 'shareware', I recently got several disks in an attempt to find a
couple of utilities for specific tasks. First, nothing I've found did what I
wanted, but more importantly here, several of the things I found on the disks
which looked useful either did not work or hung the PC. In all my years of
using code from VMSHARE or the Waterloo tape (since early VM/370 days),
I can remember few problems with free VM software (except when PETAPE was
caught out by an unfortunate change in CMS).

Apparently, there are three storage values: the one in the Hercules configuration file, the one specified in DMKSYS, and the one in the VM directory.

On MAINT, q stor gives the value in DMKSYS, and q v stor gives the one in the directory.

Specifying a Hercules value greater than the one of DMKSYS does not make any difference; with a smaller value, the system won't IPL.

header? and blocksize of 16005 for tape records (use of 'BLKSIZE' option allows
user to specify blocksize up to 32005).? Also allows user to write tapes in PLC
format.? All IBM formats (old 800 byte and new 4096 byte formats),? old PE
format, and PLC tapes can be read, and they all can be written except? for the
old PE format.? Also, the tape command will consist of two modules.? For more

q stor response on an unmodified VM/370r6 setup

 

Hello!
There's a thread running on the IBMVM list that discusses the amount
of storage available to someone making use of everything on zVM and on
a practically new system. One of the people on that thread asked if
the individual tried the q stor command sequence. And as it happens he
was making use of the MAINT id which is a class A one. It did indeed
return the right amount for that system.
But here's what it returns for anyone just getting started with both
Hercules and VM/370.
q stor
R; T=0.01/0.01 20:54:12
STORAGE = 02048K
R; T=0.01/0.01 20:54:12
That's the response from the Bob Abeles two pack system that he
graciously bestowed on us sometime ago. Hercules is the one that Fish
announced for us sometime ago. I see I need to change something on it
regarding crash dump reporting.
