Re: Fwd: Re: VSAM to DB2 Migration (on the mainframe)

[ThSITC]

Hi Bernard, Etienne:

(not copying the rest, more *not* technical people).

All of my Software is nowadays written In NetRexx (see: www.netrexx.org), which is:

a) Generating Java Code, in turn
b) does run, by design of Mike F. Cowlishaw, former (or still current) *inventor of NetRexx*, back in the 1990's,
*on any and all Machines* having a *Java JVM* ...

Whil'st I don't have (yet) personal Practice and *exper* as well for running NetRexx programs on an
IBM mainframe, *for sure*, any & all of my programs *do run* on any Java Machine.

I'm copying here Rene Vincent Jansen, *current President of RexxLA (www.RexxLa.org)*,
as well as MFC (Mike F. Cowlishaw, *original author* of both *classic Rexx*, as well as
*NetRexx*, for their comments or advise, when necessary.

Also Walther Pachl, here in Vienna, who did *help a LOT* implementing the PL/I
Version of DB-123, years ago ...

Greetings from Vienna, Austria, Europe (*no Kangoroohs*, I'm really sorry about that <grin, and smiley>)
Thomas Schneider.

PS: Bernard,

Rene Vincent Jansen is actually running HERCULES on his MAC, which
does even *emulate a MVS machine*, on his Mac!

+AND+

with the ibm-netrexx *group* (which I do copy just for their info) we will have an
*international* and *very experienced* group of people knowing all the details
we shall encounter in this project ...

Any Number of IBM-employees *and/or* ex-IBM employees (real experts)
there in ...

Thomas.

Hi Thomas,

I am no sure your solution is what we expect.

- As you know , we have our own mapping solutions for z/OS to Open system  (linux, UNIX, Windows)

- In this case we need a Mainframe z/OS only solution where the VSAM to DB2 migrated files will work for a significant time.

Can you do that?

NB: I do not see the attached questionnaire?

Kindly
Bernard

Hi Thomas,

Thank you for your prompt answer.

At this time , we are not directly onvolved on this project, but only behind another partner.

However I think it would be good for us to partner on this.

I have a few preliminary questions:

-  Have you any other reference than DONAULAND?

*NO*, as the *it-gents* (Roland Dippelreiter, Gerhard Tomicek, Werner Schüpferling), who did have
*the WORLDWIDE Exclusive Sales rights* (by their contract between *me* and *them*)
didn't sell anything, for various reasons...

- Did DONAULAND (or others) migrated VSAM to DB2 on he mainframe?

DONAULAND did migrate approx 10 VSAM ESDS File (on the Bertelsmann IBM VSE Machine in Güthersloh),
at *once with some other* approx 100 IBM DL/I Segments *at the same weekend* from
IBM COBOL I and IBM COBOL II (remember: I did implement the IBM COBOL Report Writer,
too, long years ago) *to* MicroFocus Cobol. The approriate Product, those times,
has been called *Cob2MFC*  (IBM Cobol to MicroFocus COBOL)

Thus, we did (using my Software Generaotrs, and Utilities) migrate *the whole application*
*over a weekend*, with Success, *and without any interruption in the DAILY Work* of the
*clerks* involved, after the Year 2000, and the EURO Transition, as well.

I have been the *Project Leader* fro Y2K, as well as the EURO-Transition, where
many of the tools I did have been actually developped, and, based on this Experience,
I did DESIGN and DEVELOP Cob2Mfc, as well as DB-123, afterwards.

Hence, we *actually* did migrate both the Source Language(s), namely ancient IBM COBOL I,
*including Report Writer programs*, and IBM COBOL II, as well a newer programs with IBM.
COBOL LE, with VSAM, IBM DL/I Files, and approx already existing 120 IBM DB2 (SQL)
Files from *any Machine* (an IBM VSE Machine there in Gütersloh), over the IntraNet
of Bertelsmann *to* a Windows NT/IBM DB2/MicroFocus Environment *successfuly*
*over 1 weekend*  (after 1/2 year of *careful testing*) *without any problem (0 FAULTS!)

I have been, at those days, the *architect* of this solution, which has been 100%
TOOL Driven ... 

::: still feeling well, that I did deliver ON TIME, ON BUDGET, what I did promise
1 Year before (based on my prior expertise(s) with those kind of projects fro decades)

- What is your economic modem and what would be the price estimate?

No idea, unless you do fillout the questionaire (attached)

- We talk about 35 VSAM files, which we have not the content at this time

DB-123 algorithms are based on the COBOL *COPY BOOKS* defining
the File-Structures in DETAIL! Multi-Type-VSAM Files *are supported*,
by the way :-)

- Etenne can probably send you some other sampels, for instance that we have used in previous migrations

Great, thanks!

I'm just searching my ancient directories for the *sample* of a VSAM File migration ...

I'ts soooo *ancient*  that *I do have to rewind my wheels* in *my small brain* (joking, Bernard, of course!)

Kindly
Bernard

PS: As a *Post-Script to the it-gents* ...

You did your best, but you did *never* actually think about, how to *reach*
the international market! Thus, *giving you* (the it-gents) the *worldwide*,
*exclusive*, *marketing right* has probably been, from my point of view,
a *failure* and also, a *wrong expectation* (from my side).

But: *Nobody of us can change the past*

Thus: REQUIESCAT in PACE (The Past, and the HISTORY, as well) ;-)

Hello Etienne, Bernard,

*since it's first creation*, some 10 Years ago, db-123 (technical Doc on www.db-123.com)
does and did support:

  -- Conversion of simple Indexed Files (VSAM ESDS *or* KSDS)
  -- Hierarchical Databases (as IBM VSE DL/I, *or* IBM IMS)
  -- NetWork Databases (CODASYL DBTG Databases, as IDS II, Cullinet, etc)
 
by means of our *proprietary* DB-123 Data Dictionary.


That's also, where the Product Name (DB-123) came from :-)

For VSAM Files, a special Pre-Processor parses the related COBL (and nowadays, also: PL/I)
programs *and does* actually *replace the original* COBOL (or PL/I) source statements
*always* to the *so called ACCESS-Routines* Generated by DB-123, in Turn.

Of course, it does also CATCH the VSAM I/O error Codes tracking in ON ERROR etc,
and does *transform* those to the proper SQL Codes.

We did use *this technique* in the DONAULAND Transformation from
Bertelsmann's IBM VSE Machine (with VSAM and/or DL/I) to the
MicroFocus+Windows NT+IBM DB2 *transformation* successfully,
I think, now, nearly 8 years, or so, ago.

I do have admit, however, that I will have to review this *ancient code*,
I wrote, again.

Best choice, at the minute, would be that Etienne does send me an

Ordinary ZIP File

with all the sources (and INCLUDES) please,

involved.

I then could Analyse, Parse, and Transform it with the recent
Software version, and see whether I did introduce some faults
with all the Updates to my soft I did make the past 7-8 years.

*For Sure*, I would be interested in *your project*, anyway!

Etienne might contact me:

Either on: [hidden email]
*or*    on:  [hidden email]

Best thing would be, taht Etienne / you do send me a mail,
where we can agree on date & time, as I am quite a bit
out of my office, sometimes...

Kind regards to both of you,
Thomas.

Dear Thomas,

One of our collègue asks us about such a solution.

- It will have to work both with CICS  AND batch COBOL programs

- TP and batch can be simultaneous on these VSAM files

I did not see the details on your web site http://www.db-123.com

If you can I think it would be intersting that we have a Skype with etienne MICHELI.

Thks for your reply

I'm trying to get the GuiApplt.nrx code to compile with a line of code to execute a class I have that I may want to execute from  the command line of from within a page of html.
Maybe I am on the wrong track. Maybe I should be looking into JNLP.
Is this compile error something easy to fix? Or would it require a lot of complex coding?

Hi Kenneth,

consider the following, which compiles:


   method init()                            -- APPLET and APPLICATION
     trace results
     super.init()
     this.setLayout(null)
     f = SimpleDateFormat("H:mm:ss")         -- formats
hours:minutes:seconds
     text1 = Label("Init at:" f.format(Date()))
     text2 = Label(" ")
     this.add(text1)                         -- add the labels to the
window
     this.add(text2)
     text1.setBounds(40,30,120,15)           -- and size them
     text2.setBounds(40,50,120,15)
     do
       out = BufferedReader(FileReader("test.file"))
     catch x=FileNotFoundException
       say '# error opening file' x.getMessage
     end


because init overrides the init method of Applet, it cannot have
another signature, so you have to catch the exception in the method
body, and cannot declare that it throws it.

You did not do anything to cause an exception in the init method, so I
openend a file for you. The shown syntax is the correct one, I am not
entire sure what you intended with the select clause.

hth,

René.

Hi Kenneth,

consider the following, which compiles:


  method init()                            -- APPLET and APPLICATION
    trace results
    super.init()
    this.setLayout(null)
    f = SimpleDateFormat("H:mm:ss")         -- formats
hours:minutes:seconds
    text1 = Label("Init at:" f.format(Date()))
    text2 = Label(" ")
    this.add(text1)                         -- add the labels to the
window
    this.add(text2)
    text1.setBounds(40,30,120,15)           -- and size them
    text2.setBounds(40,50,120,15)
    do
      out = BufferedReader(FileReader("test.file"))
    catch x=FileNotFoundException
      say '# error opening file' x.getMessage
    end


because init overrides the init method of Applet, it cannot have
another signature, so you have to catch the exception in the method
body, and cannot declare that it throws it.

You did not do anything to cause an exception in the init method, so I
openend a file for you. The shown syntax is the correct one, I am not
entire sure what you intended with the select clause.

hth,

René.

I see a difference -- my version of the init method did not SIGNAL
anything
so you'd have to correct that line.

best regards,

René.
