DCB mismatch for FBA dataset in report pgm

morpheus007 · New User Joined: 27 Dec 2005 Posts: 58

I am working on a report program where in cobol the record structure is declared with length 132.In the JCL the DD is declared as:
LRECL=133,RECFM=FBA,BLKSIZE=1330

When this is moved to PROD it abends with a DCB mismatch and file status=39 with file open failing.

Kindly let me know what should be the fix for this.

Hi Morph,

I assume you mean to say that the identical JCL/pgm code works in test.

If so, your test/prod compiler options may differ. You might want to give them a look.

Are the allocations correct.

Should I be changing the JCL attributes to LRECL=132 FBA or should I be changing the cobol declaration to 133.

This looks more of a runtime fauilure to me.The dataset got allocated and when cobol tried to open the file it failed as the attributes did not match.Hence status code=39.

Hello,

As Jack asked, does the EXACT same JCL work in test? Might it be that in test you use "SYSOUT=" but in production a dataset name and dcb parameters are specified?

If it IS a sysout dataset in either/both environment, i'd suggest leaving out the dcb info.

If you need to create a "print file", modify your FD to be length 133 and add 1 byte of filler before the printable info and see if that corrects the abend.
