Thoughts on DFSMShsm ABARS in today's environment

[Lizette Koehler]

List -
I am currently working with ABARS process.  As I get into it, I was wondering 
with today's Storage Array, Replication, Snap, Flash Copy, is it still needed?

Are there any significant reasons to setup and maintain an ABARS process?

The one answer - It was setup years ago and works fine - is already noted.  But 
what about a shop today.  If you are not running ABARS would you see a reason 
to use it?

If you are running ABARS, what does it provide you in your shop for your 
applications?

Thanks for the input

Re: LOOKING FOR INFO

[Christopher Mason]

That means you can support up to 96 controllers does not necessarily mean
you have that many. There are a few ways you can figure out how many
controllers you have.

1. Physically go to the F05 frames(cabinets) and look to see how many
controllers you have. Not sure what flavor you have C06(P5) or C07(P7).

2. Look at the tape devices in your IODF and view the device there will be
a LIBPORT-ID associated with the devices. Each LIB-Port is a controller.

3. In your IOCP each Control Unit defined for your tape drives in the
library will be a controller.

Re: New zPDT redbook

[Vince Coen]

Mike;

There must be more to it in migrating a program (Cobol compiler ) 
written in C that uses many Linux components (Bison springs to mind but 
there is a lot more) that accesses files both in the current directory 
and in specific one's (e.g., /usr/local/lib/  and others).


I do not think just recompiling using the IBM C compiler is enough 
somehow. Otherwise it would have been done some time back - unless 
someone knows better ?



As it is I can use the compiler's in OS/390 or Z/OS such as :

IBM COBOL for OS/390 & VM  2.1.2

or

IBM Enterprise COBOL for z/OS  4.1.0


But there appear a lot more complex for building a few simple accounting 
applications that I have running under gnuCobol on Linux that I have now 
made Open Source on sourceoforge.


A long time ago they did use CICS (1970's) but al that was replaced 
using SCREEN SECTION which has its own problems if running in a GUI 
environment such as Linux KDE/Gnome or even - if you have to - Windows)


I am not really up to putting CICS back into them assuming is has 
seriously been improved for working on PC's -0 which I doubt.


Possibly better to try and change them to support using via a web 
browser which would be a long - process as I have never tried such, but 
hay, I am retired with a far bit of time on my hands.


The other issue I have is trying to work out how to get any kind of 
printed o/p from both O/S's to my PC and then to a PDF file as I have 
under MVS 3.8.  JES2 only seems to understand a 3800 and not a simple 
one like a 1403.  The former is far to fancy in its handling to just 
transfer over to a PC and print out without a lot of control and other 
junk chars getting in the way.  Not helped by the JES2 paramw able to be 
in so many different places in the system - applies to both OS's.


There was a time - OK, MVS days when you could get 1/2 books that would 
cover most of what you needed to do and give references to the primary 
IBM docs for the others but that seems to have vanished now with the 
current O/S crop - or is it I am getting to old (68 shortly)!

At least the later Cobol compilers tends to work a lot better than ANSI
Cobol which was always a dog at least on the site's I worked at so when
OS/VS Cobol came out it must have been the fastest migrations in history

Pity I can't find a more recent compiler to use under MVS Turnkey 4 Upd

Now the next trick and no I don't know how is to migrate GNU Cobol v2.n
(was
Open Cobol) over to it which has a few functions over the current IBM
offerings.

OK, may be not in my lifetime.

The TS3500 Tape Library can support up to four 3953 tape systems, up to eight

We have 6 libraries.  So if my math is correct there are 96 tape controllers.

Re: Extended SMS routine

[Darth Keller]

A small suggestion for the code below would be to add a unique identifier to 
each WRITE Statement.   It seems like every company I've implemented SMS in has 
constructs which are assigned at multiple points in the code.  

If that were to be true in this case,  it would be more difficult to determine 
at which point DSOMEDC was assigned.  I've found it to be very helpful to add 
identifiers like
 WRITE 'DC000100 DATACLASS SET to ('&DATACLASS')'
Each DC# is unique to that WRITE/EXIT combination.  When debugging an issue, it 
can speed things up as your EXIT point is immediately identified.  You can also 
add some of the WRITE variables to help you in debugging the issue like &DSN, 
&DD, &ANYVOL, etc.

//

IF &DATACLAS EQ '' THEN /* HONORING SPECIFIED STORAGE CLASSES*/
   SELECT  
WHEN (&DSN EQ &WHATEVER) 
  DO   
SET &DATACLAS EQ 'DCSOMEDC'
WRITE 'DATACLASS IS SET TO ('&DATACLAS')'  
EXIT   
  END  
WHEN (&DSN EQ &SOMETHING) 
  DO   
SET &DATACLAS EQ 'DCOTHER'
WRITE 'DATACLASS IS SET TO ('&DATACLAS')'  
EXIT   
  END   
(repeat as needed)   
OTHERWISE  
  SET &DATACLAS EQ ''  
   
   END /*  END SELECT  */

Subject: Re: JES2 as primary with JES3 as a secondary

Karl,
If you are not aware - there are also a JES2 and JES3 list.  If you would like 
to join, go to these URLs

JES2http://listserv.vt.edu/cgi-bin/wa?A0=jes2-l
JES3http://www.listserv.uga.edu/archives/jes3-l.html

The biggest difference I see is that JES3 needs to know it owns resources 
before it will let things run.  JES2 does not.  That may be a consideration in 
trying to run JES3 under JES2
