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 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
