Generating the MVS 3.8J Tur(n)key System

Software Requirements

Sysgen System directory structure

When you installed the Tur(n)key sysgen system, a target directory (default mvs38j) was created with a few subdirectories in it. The directory structure is like this: 

+ mvs88j                 installation directory
!
+------ conf             configuration and control files
!
+------ dasd             pregenerated dasd images
!
+------ hercules         binaries needed for Hercules execution
!
+------ jcl              contains the SYSGEN Job Control Files
!
+------ log              contains log files created during sysgen
!
+------ scripts          shell scripts used during installation
!
+------ shadow           directory for cckd shadow files
!
+------ snapshot         Snapshots made during sysgen
!
+------ tapes            Directory for tape files

When you need to run command files, you will find them in the "scripts" directory. The command files for windows have the extension ".BAT", while the Linux scripts have no extension at all. Actually, most of the Windows command files don't really do very much, except invoke the bash interpreter which in turn runs the Linux shell script

Note that the Hercules version must have support for compressed disks and tapes included, as all files used by this generation are compressed (using zlib)

If in doubt, use the Hercules version provided in this package, it has the necessary compression enabled

Now the real fun starts. You first have to build a starter system. Don't worry, this is really not difficult. Just run the Installation script

Table of Contents

INS0010 - Build Starter System

This scripts unpacks the starter system from an archive provided in the "snapshot" subdirectory of the CD-ROM. It then builds some more DASD images

After the volumes have been built, the script now automagically runs Hercules for initializing the volumes.

You now should start a telnet client to connect to the Hercules instance. Switch to another Windows or Linux session and invoke the starttelnet script (which starts the telnet client).

If you want to invoke telnet directly make sure that your telnet client connects to port 3270 on the machine where Hercules is running. (Actually, the port number is set during the Tur(n)key installation. I am using the default (3270) here, but you could have chosen a different one. To start a telnet client, you could enter 

telnet localhost 3270
or, if the Hercules system is on another machine than your telnet client: 
telnet hercbox 3456
where hercbox is the name of the Hercules machine and 3456 is the portnumber that you selected during installation

Please note that "3270" has no relation to the device type of the console you want to connect to the Hercules engine, it is the port number you use for the connection. "3270" is as good as any other availble, non-reserved port number.

Once the Hercules engine is started, and the telnet client has connected to it, you can now IPL the stand alone init utility. On the Hercules console you enter 

ipl 00a
or, on the semi-graphical console that you reach by pressing the ESC key you enter 
l b
After a short while the system should enter an enabled wait. Switch over to the telnet console and press the [enter] key once You will see something like: 
IBC105A  DEFINE INPUT DEVICE. DASDI  7.92
HHC901I Enter input for console device 0009
to which you answer (by typing at the telnet console): 
input=1442,00c
and again pressing the [ENTER] key once. The telnet console should now show: 
MVSRES JOB   'INITIALIZE 3350 MVSRES VOLUME'
       MSG   TODEV=1052,TOADDR=009
       DADEF TODEV=3350,TOADDR=148,IPL=NO,VOLID=MVSRES,BYPASS=YES
       VLD   NEWVOLID=MVSRES,OWNERID=Hercules
       VTOCD STRTADR=1,EXTENT=29
       END
and similar messages. Be patient, the system is now initializing the disk packs, and that will take a few minutes. When you see the message 
IBC163A  END OF JOB.
       LASTCARD
then the disks are initialized, and you can now terminate the Hercules engine and the telnet client

The Hercules engine is terminated either by typing 

quit
on the Hercules console, or, if you are using the semi-graphical console, by pressing 
W
(for poWer off) and replying to the prompt.

By the way, if you now check the scripts directory, you will see that the script ins0010 has disappeared - It relocates itself automatically into the subdirectory done. Why? Well, this makes it more difficult for you to run the script again accidentially, wiping out all the work done....

INS0020 - Write IPL Text to MVSRES

Invoking the command script ins0020 will now (again) start the Hercules emulator, but with a different configuration file. This time, after the telnet client has connected, you will want to start the MVS starter system by entering 


ipl 150
where 150 is the device (cuu) address. on the Hercules console!!.
Alternatively, you can switch to the semi-graphical console and press 

l e
to IPL off device E (where E is the device shortcut letter After a few seconds, the telnet session should show 

IEA101A SPECIFY SYSTEM PARAMETERS FOR RELEASE 03.70.VS2
HHC901I Enter input for console device 001F
Now you enter 

r 00,clpa
because this is the first IPL of the starter system. If you start the system at some later time, you can just press the [ENTER] key as a CLPA is not generally required then

After about a minute or two you should see 

 IEF165I // START JES2
 IEE351I SMF SYS1.MAN RECORDING NOT BEING USED
*00 $HASP426 SPECIFY OPTIONS - HASP-II, VERSION JES2 4.0
To which you reply

Again, this is only required because this is the first time that JES2 gets started, and the spool dataset SYS1.HASPACE needs to be formatted. If you start the system later, you would enter 
 r 00,,noreq
Back to our IPL, though. A message will now be displayed 
*01 $HASP436 REPLY Y OR N TO CONFIRM CHECKPOINT RECORD CHANGE
to which your reply is 
r 01,y
Again, you need to be patient, JES2 is now formatting the SPOOL0 volume. When everything has been formatted, you will see

Also, Hercules will now feed a job with jobname sg0000 to the started JES.

You should now enter the following JES commands 

$SPRT1
$SPUNCH1
to enable printing/punching of job output.

After the job sg0000 has completed, you will find the output in the prt subdirectory with the name sg0000.lst

Running Sysgen Jobs

The JCL to be run for the system generation are in the jcl subdirectory. To submit a job in file sg1234 you have three possibilities:

  1. devinit 012 ../jcl/sg1234 eof
    on the Hercules console
  2. n b ../jcl/sg1234 eof
    on the semi-graphical Hercules console
  3. via the socket device reader. On a standard Linux screen enter sub sg1234

Sometimes it is nice to see the JES2 assigned job numbers when diplaying MVS information via operator commands. You can achieve this by entering 

$T OSC1,D=J
If you would also like to see a timestamp on every message, then enter 
$T OSC1,D=T
instead

You might also consider to issue the MVS command 

mn jobnames,t
which tells MVS to monitor and report on start and end of jobs.

All jobs that need to be run on the starter system have names beginning with sg followed by a number. Other jobs in the jcl directory will be run from the generated MVS system later

The output of jobs run go to the printer device at address 00E. This device is usually connected to a file prt00e.prt in the prt subdirectory. Using one of the folllowing commands

redirects the output to the specified file.

Every jobstep generates a Return Code (RC), a number between 0 and 4095. Usually, a 0 (zero) means success, and if the RC gets larger, it means a more or less serious error. Unfortunately the RC messages get sometimes overlooked. Therefore I have provided a shell script (cond) that will extract only the Return code messages and display those. You should copy this script from the scripts directory into a directory of your path, like /usr/local/bin

SG0010 - Prepare for Sysgen

The SMP4 that is distributed with MVS is unfortunately unfit for system generation!! Fortunately, a replacement is available. This job will copy it from a work file into the starter system's SYS1.LINKLIB.

While we are updating some system files, we also add a few procedures to the system procedure library

Please note that you cannot read the socket reader device (sub command) right now, as the reader was not set up to bind to a port. You should use the command 
devinit 012 ../jcl/sg0010 eof
After this job is run, an IPL is required before SMP4 can be used.

IPL - Pick up the new SMP4

As already mentioned an IPL is now required. No, don't press ctrl-alt-del yet! At the telnet screen (which is the MVS master console) enter the commands 

$p
$pjes2
z eod
quiesce

We don't really need it right now, but you should do it anyhow, just to learn about it: Terminate the Hercules emulator (quit on the Hercules console or poWer on the emi-graphical console. We can now restart the starter system with a warm-start:

Table of Contents

STARTSTARTER or INS0030 - Start the Starter System

The script file ins0030 has a twin, called startstarter (easier to remember). It can be used to start the MVS starter system. Remember that you will have to start a telnet client on port 3270 (using the tn script or the starttelnet script)

When the message 

IEA101A SPECIFY SYSTEM PARAMETERS FOR RELEASE 03.70.VS2
HHC901I Enter input for console device 001F
appears, you now (remember, this is a warm start) just press the [ENTER] key. After a few moments you will see 
 IEF165I // START JES2
 IEE351I SMF SYS1.MAN RECORDING NOT BEING USED
*00 $HASP426 SPECIFY OPTIONS - HASP-II, VERSION JES2 4.0
To which you reply 
r 00,,noreq
Shortly afterwards the warm start is complete.

Please note that the Reader is now set up as a socket device, with other words you can submit jcl streams via the sub shell script. You could copy the script sub into a directory in your path, like /usr/local/bin

Note that the script ins0030 does not move itself to the done subdirectory, as it will be needed more than once

SG0020 - Create Master Catalog

The MVS system to be generated needs a mastercatalog. We will place it on the new system residence, and connect it to the starter system as a user catalog. Just run job sg0020 and see what happens...

SG0030 - Allocate DLIB files

The DLIB (=Distribution LIBrary files) contain the building parts out of which the target system (the MVS to be generated) will be built. We allocate empty DLIB files using job sg0030. Later, these files will be filled via SMP4. Therefore we need to initialize the SMP environment as well.

SG0040 - Receive product tape

Now we have to feed the product tape to SMP, which will unload the parts from the distribution tape and place it into temporary libraries on the MVSRES volume. (That is the volume that we specified on the TLIB parameter of the SMP4 procedure in job SG0010).

The distribution tape is in the file zdlib1.het, and you load the tape drive by entering 

devinit 170 pathname/zdlib1.het
where pathname is the path to the directory containing the tape file. The file is usually in the tapes subdirectory of the CD-ROM. Now submit job sg0040. Be patient, this job has a lot to do, and it takes quite some time to complete!

Okay, so the long wait is over. What are we going to do now? Well, it is time for a snapshot.

Table of Contents

INS0040 - Write Snapshot # 1

You have invested quite a big amount of time and effort so far. Wouldn't it be a shame to loose it all, just because, like, by accident you reran command file ins0010? Better safe than sorry, thus let us create a backup.

First shut down MVS and end the Hercules engine. Then invoke command file ins0040 which will use TAR to create an archive in the directory snapshot. This archive contains the contents of the following subdirectories:

If you want to change what is written to the archive, you need to modify the writsnap shell script.

A volume can be recovered from a snapshot using command script restsnapvol. The syntax is 

       restsnapvol {snapshot} {volume}
                   !          !
                   !          +--- volume of disk to restore
                   +-------------- snapshot number (01, 02, etc)


Example:  restsnapvol 01 mvsres

to restore volume MVSRES from snapshot # 1

A complete snapshot can be restored using the command script restsnap. The syntax is 

       restsnap {snapshot}
                !
                +-------------- snapshot number (01, 02, etc)

Example:  restsnap 01

to restore the complete snapshot # 1
After the snapshot is complete, you can now restart Hercules, the telnet client, and MVS

SG0050 - Receive product maintenance

No software product is without bugs. This is (especially) true for MVS. In the course of time fixpacks etc have been developed. IBM call the fixes PTFs. Ever wondered, what PTF stands for? Well, PTF = Program Temporary Fix . This tells you a lot about software maintence, doesn't it?

Okay, some of the fixes are available to us. A tape with accumulated PTFS is available, with the name of MVSPTF. Submit the jog sg0050, and a mount message will promptly appear on the MVS console. The emulated tape file has a filename of allptfs.het and is in the tapes directory on the distribution CD-ROM. You can now load the tape drive from the Hercules console by entering 

devinit 170 tapedir/allptfs.het

The maintenance on the tape will now be received. This will take some time, as there are many hundreds of PTFs loaded into the system.

SG0060 - Install BTAM

For some compelling, SMP related reason it is necessary to install one specific product before all the others. Install in this moment means: Load the information from the SMPPTS and the SMPTLIBS (where they have been placed by the RECEIVE commands in SG0040-SG0050) onto the DLIB files on MVSRES.

This will be done using the ACCEPT command of SMP. Usually, though, a SYSMOD will not be ACCEPed right away, but needs to be put into the Target Sytem for testing first, which would be done via an APPLY command. But we do not have a target system in the moment. Therefore the parameter NOAPPLY on the ACCEPT command is required to tell SMP that the FMID should be ACCEPTed even though it has not yet been APPLYed.

If you don't want your SMP jobs to run forever, use DIS(WRITE) as an additional option on the ACCEPT command. This keeps the directory of the highly used PDS SYS1.SMPACDS in memory, instead of incurring gazillions of disk I/O operations. If things go wrong, though, your SMPACDS might be seriously broken... Guess why we did a Snapshot in the previous step!

I also ran the same job under Linux on a 150MHz, 80MB Thinkpad. It was not exactly fast.....

INS0060 - Another Snapshot

After such a massive change to our system it might be a good idea to take another Snapshot. Shutdown MVS and the Hercules engine, then run command script ins0060, which puts new files into the snapshot directory. Don't throw away the previous snapshot files - you never know....

SG0140 - Implement Support for new DASD devices, part 1

The brightest and finest DASD type supported by MVS 3.8J was the 3350 DASD, which is perfect enough, usually. Now, there are quite a few libraries around (like on the CBT tape which were built for more modern DASD types, like the 3380 or the 3390 DASD types. Enter Jim Morrison(no, not the one who is permanently in Paris). He has done some marvellous work and retrofitted support for 3375, 3380, and 3390 DASD devices into MVS 3.8. While there might be still a few rough edges, these modifications allow us to use those larger DASD files for general purpose processing.

Why would we want/need those devices? Many of the CBT provided programs, utilities, etc come in XMIT format for 3380 and/or 3390 devices, and the blocksizes don't really work for 3350 devices.

Running job sg0140 will RECEIVE the modifications into our new system.

SG0150 - Implement Support for new DASD devices, part 2

No harm is done yet. In order to actually do the necessary modifications to system macros etc you need to run the job sg0150

The DASD support modifications are implemeted as USERMODs. What is the problem? Those USERMODS need to be ACCEPTed, as they modify the system generation (SYSGEN) process. And IBM doesn't know about those retrofitting USERMODs, with other words, PTFs that affect the same elements that are modified by the USERMODs will get an ID check and cannot be installed, unless we do some additional processing. Thus, if you are faint of heart, you might want to skip this step. Remember, though, that in this case

Expected RC
4

The reason for RC=4 is that new modules get introduced into the DLIB system that SMP4 does not yet know about. You will see messages like 
HMA2471 BLDL FAILED IN LIBRARY AOSD0 FOR LOAD MODULE UTRK3390 IN SYSMOD M023000
HMA2471 BLDL FAILED IN LIBRARY AOSC5 FOR LOAD MODULE USRDDT00 IN SYSMOD M024001
HMA2471 BLDL FAILED IN LIBRARY AOSD0 FOR LOAD MODULE UTRKCALC IN SYSMOD M024001
which indicate this fact. You can safely ignore these messages and RC=4

We have installed all the functions of MVS available to us. The service (PTFs) has only be RECEIVED, we will implement them at a later stage.

SG0160 - Sysgen, Stage 1

Finally! There are quite a few comments in the stage1 assembly deck, and I would recommend that you take a look at the deck before running job sg0160. One paramter might need to be adjusted: Around line 506 you will find an entry like 






which controls the time setting for the Hercules machine.  It is set to Germany (1 hour East of UTC).
You might want to adjust it to your local time setting before running this job.  Instead of editing

the system by dedicating the better part of a full volume to the spool, but we will wait until we are
certain that our generated system will start successfully.

SG0200 - Update SYS1.PARMLIB



A few changes are needed to SYS1.PARMLIB members.  These changes will add SYS1.CMDLIB
to LNKLST00, select a different IEAPAK00, etc.  Run job sg0200 to implement
the changes.   After this job has completed, shutdown MVS and the Hercules engine.

STARTMVS or INS0100 - Start the new MVS

Edit the script startmvs or its twin ins0100
to start the 3270 client you want to use.  You will at least
need 3 sessions, 2 for console support, 1 for TSO.
You will also need one telnet client.  You should not IPL MVS until these clients have
connected to Hercules




on the Hercules onsole, enter the command

ipl 148


to IPL MVS off the newly created MVSRES volume.
This is the first time MVS 3.8 is IPLed, therefore an MVS CLPA is required, and later
a spool formatting JES2 start.

During IPL with CLPA you will see the following messages:

  IEA101A SPECIFY SYSTEM PARAMETERS FOR RELEASE 03.8 .VS2


to which you reply

r 00,clpa


You may or may not see messages like this:

After MVS is started there are three printers in the

Issue the JES2 command

$T prt2,Q=Z


to make the second printer serve the output queue Z.  This might be handy sometimes later.




At some time during startup you will see a message similar to

*$HASP190 DUMMY    SETUP -- PRINTER1 -- F = STD. -- C = 6    -- T = 0


When this setup message appears, you must start the corresponding printer, in this case by entering

a JCLIN process as in SG0340 will feed these instructions into
SMP4. SMP will then be able to rebuild elements of the MVS system

SG0350 - Install A Usermod



To test the SMP4 environment we will install a simple usermod which
will authorize some external commands to TSO.  We will install these commands later,
for now we will be happy when the usermod gets correctly installed.
Just run
the job SG0350 and check that the module IKJEFTE2 gets linked
correctly.







Expected RC


First time: 12


If repeated: 4






Why don't we get RC=0?  Very simple, in order to make it possible to rerun
this job, I put in a command to REJECT the usermod first.
Obviously, there is nothing to reject, that gives the RC = 12.  If the job is later rerun,
then the REJECT will work, but gives a warning (RC=4) because the usermod being rejected has not
been ACCEPTed.

Note:  Don't ACCEPT this Usermod!!

SG0360 - Exclude broken PTFs



We have installed all the functions of MVS that we have.  Unfortunately, our install work isn't
finished yet.  Many, many bugs have been found in MVS over the years, and were fixed
(more or less)  by IBM.  We have an accumulated tape of PTFs, that we already RECEIVED.
We can now ACCEPT those PTFS to avoid known problems to happen later (preventive service).
Another approach would
be not to RECEIVE all PTFs, but only install those that
fix a certain error situation we know does exist in our system (corrective service).
Both approaches have their merits. I decided to use the first approach, and to install
all PTFs that are currently available.


Actually, not really all PTFs. The PTF UY49086, for example,
(at least on my system) breaks SVC94 (which is used for TPUT, TGET, GTSIZE et al) and makes
part of TSO (like TEST) unuseable.  It also breaks a SYSGEN macro.  Fixes for this
are only available in an additional product which we do not have available.  Therefore
we need to exclude UY49086 from our APPLY.  Now, there are some PTFs that name
UY49086 as a PRErequisite, and those need to be excluded those as well


The job SG0360 will remove those PTFs from the SYS1.SMPPTS.   That we we are absolutely
sure that they cannot be installed even accidentially.  But -  we don't want to loose those
PTFs, either.  Therefore we save them in a special dataset: SYS1.BADPTFS

SG0370 - Fix PTFs



Some PTF have incorrect element relationship entries (PRE, REQ, etc), others cannot
be APPLYed because of out 3375/3380/3390 USERMODs.  Why not?  The USERMODs modify
elements, which later would be modified again by the incoming PTFs.  Of course those
PTFs don't know anything about the USERMODs, and therefore don't name them in the PRErequisite
chain.  Thus - ID check processing SYSMOD ......   Does not PRE or SUP .......



We solve the problem by explicitly adding the correct PRE/SUP statements to the affected
PTFS.  We also supply new USERMODs that retrofit the 3375/80/90 modification to the new
SYSMODS.  All of this is done by running SG0370.
The PTFs get saved first into SYS1.BADPTFS before being modified.

INS0120 - Shutdown and create snapshot # 5



Before we are going to run a monster mass-apply job we make a backup again.  Shutdown VTAM, JES2, MVS and
Hercules, then
run script
ins0120 which will create snapshot # 5

SG0380 - Mass Mode APPLY of all SYSMODs


Okay, it is time for the big showdown.  We have nearly 1500 PTFs in our SMPPTS, and want
to install them into the running system.  This probably is going to take a while..... Start
up Hercules, then MVS.  Submit job SG0380.   Sit back and relax

On my P IV with 1.7 GHz and high-speed SCSI disks this job took about 45 minutes

SG0400 - Reject/Purge of accepted Sysmods


This job is optional,  If run, it will


In a space constrained environment one would run this job.  Not running the
job keeps a lot of dasd space used, but, on the other hand, you have the
cover letter text for all PTFs easily available by just browsing the
SYS1.SMPPTS.  With other words, it is a matter of taste, and

Before we proceed we make another snapshot by running script ins0130




After that, we take a deep breath



 


MVS System Generation Is Complete


 


But ....


.....
we still have some customization to do.  This is described in the document
MVS Customization.
