It's not ambiguous at all. Had it been a response to the first sentence then it 
would have directly followed the first sentence.

You used a computer to send that, didn't you?  See, I can write irrelevant 
questions too. I never suggested that there were no such zaps.

The obvious meaning is that while they are technically legal the SMP 
documentation warns against them.

Not even close.

Why do you want me to comment on statements that are not in dispute and that 
don't seem to require clarification?

You cited TWO sentences and commented it "No." Can it be shorter and
more ambigous?
However YES, there are ZAPs to change it in original IBM code. Aren't
there?
Regarding the second sentence - I used quotes. Why? What could it mean?
Maybe this: ZAP can be done without SMP/E, just load module
modification. Can't it be? Caution: I don't say it is good practise.
In that case such ZAP is somehow illegal from SMP/E point of view. Isn't

And last, but not least - I also wrote it is not supported by IBM. Maybe
it is not big issue, but ...isn't it true?

Oh, BTW, some answers: No, Yes, You're wrong, PKB, ABC, XYZ. Or maybe
single letter ones?

BTW2: I used SYSOUT(n) (n is some class) and it fills the expectations -
almost all IEBCOPY output is redirected to JES2. Almost all, because
some PDSes caused RC=4 and some messages were available on the screen.
Unfortunately RC=4 from IEBCOPY caused XMIT to fail.

I believe that 3120 is one of the optimal block sizes for 80 byte records on 
3330. At 3120 you get four blocks/track, at 3200 you get only three.

Long ago there were discussions here of ISPF SUBMIT's failing because
of inadequate (default?) SPACE for its workfiles.  The same might apply
to TRANSMIT.  Likewise old utilities might have hardcoded BLKSIZE
(3120?  6144?) suboptimal for recent DASD.  But if such utilities were
changed to BLKSIZE=0 the larger values supplied by SDB might cause
downstream programs to fail.

Formerly some utilities (Linkage Editor?) imposed a limit of 3120.

I had some Rexx programs fail when EXECIO removed its internal
BLKSIZE computation to let SDB operate.  Rapidly fixed by APAR,
but Support advised "Always code BLKSIZE."  An ironic consequence
of SDB.

Damn!  So I was needlessly using 3120 all those years.

It's mentioned (in an example) in:

"... Formerly some utilities (Linkage Editor?) imposed a limit of 3120. ..."
Linkage Editor //SYSLIN had a Max BLKSIZE of 3200.

Long ago there were discussions here of ISPF SUBMIT's failing because
of inadequate (default?) SPACE for its workfiles.  The same might apply
to TRANSMIT.  Likewise old utilities might have hardcoded BLKSIZE
(3120?  6144?) suboptimal for recent DASD.  But if such utilities were
changed to BLKSIZE=0 the larger values supplied by SDB might cause
downstream programs to fail.

Formerly some utilities (Linkage Editor?) imposed a limit of 3120.

I had some Rexx programs fail when EXECIO removed its internal
BLKSIZE computation to let SDB operate.  Rapidly fixed by APAR,
but Support advised "Always code BLKSIZE."  An ironic consequence
of SDB.


I have been having an issue with TSO RECEIVE (and a program that also calls IEBCOPY) when 
SDB is "Y".  IEBCOPY is having some sort of problem and displaying this message:

IEB1139W THE OUTPUT DATA SET BLOCK SIZE IS BEING REDUCED FROM 32720 TO 27920 
BYTES.  ANY EXISTING PHYSICAL RECORDS
 LONGER THAN 27920 BYTES ARE FAT BLOCKS AND MAY CAUSE I/O ERRORS.

and ending with a return code of 4.  The dataset being RECEIVEd is actually 
fine, as the LRECL is always less than 27920 (80 in this case).  But RECEIVE 
sees the RC=4 from IEBCOPY and ends with RC=12.

IBM currently has case number TS004689510 open for this, but I assumed it was a 
new issue although I only have SDB=Y on right now for testing.

I mean the following:
try the command
XMIT NODE.USER DA(SOME.PDS) OUTDA(XMIT.FILE)
and you will get XMIT.FILE as PS FB LRECL=80,BLKSIZE=3120 and that
blocksize does not look good nowadays.
We have SDB for decades, but not here. There are ZAPs to change it in
original IBM code. "Illegal" from SMP/E point of view and no supported
by IBM.
Not to mention last "few years" we have 3390 geometry with very few
exceptions. Nevermind, the only exception we can meet can be 3380. I
would bet it is possible to use a little bigger blocksize for both of
them if one wants to still support 47k trk.

Radoslaw,

Could you please elaborate on your comment "never solved issue like non-SDB (system

I have been having an issue with TSO RECEIVE (and a program that also calls IEBCOPY) when 
SDB is "Y".  IEBCOPY is having some sort of problem and displaying this message:

IEB1139W THE OUTPUT DATA SET BLOCK SIZE IS BEING REDUCED FROM 32720 TO 27920 
BYTES.  ANY EXISTING PHYSICAL RECORDS

and ending with a return code of 4.  The dataset being RECEIVEd is actually 
fine, as the LRECL is always less than 27920 (80 in this case).  But RECEIVE 
sees the RC=4 from IEBCOPY and ends with RC=12.

IBM currently has case number TS004689510 open for this, but I assumed it was a

Any thoughts?

blocksize does not look good nowadays.
We have SDB for decades, but not here. There are ZAPs to change it in 
original IBM code. "Illegal" from SMP/E point of view and no supported 
by IBM.
Not to mention last "few years" we have 3390 geometry with very few 
exceptions. Nevermind, the only exception we can meet can be 3380. I 
would bet it is possible to use a little bigger blocksize for both of 
them if one wants to still support 47k trk.

TSO RECEIVE and System Determined Blksize (was: TSO XMIT and no member list)

2021-01-20 Thread Wendell Lovewell
Radoslaw, 

Could you please elaborate on your comment "never solved issue like non-SDB 
(system determined blocksize) in XMIT and RECEIVE command"? 

I have been having an issue with TSO RECEIVE (and a program that also calls 
IEBCOPY) when SDB is "Y".  IEBCOPY is having some sort of problem and 
displaying this message:

IEB1139W THE OUTPUT DATA SET BLOCK SIZE IS BEING REDUCED FROM 32720 TO 27920 
BYTES.  ANY EXISTING PHYSICAL RECORDS
 LONGER THAN 27920 BYTES ARE FAT BLOCKS AND MAY CAUSE I/O ERRORS.

and ending with a return code of 4.  The dataset being RECEIVEd is actually 
fine, as the LRECL is always less than 27920 (80 in this case).  But RECEIVE 
sees the RC=4 from IEBCOPY and ends with RC=12.  

IBM currently has case number TS004689510 open for this, but I assumed it was a 
new issue although I only have SDB=Y on right now for testing.  

Any thoughts? 

~ Wendell Lovewell
