Hi,


I ran a job with two steps. The first step will execute a program
and create a file which will get loaded into a table in the second step.

During execution, the first step created a blank file with zero block size and
the second step failed with the below message. But the job has not failed
because of the empty file. I guess, there is issue with the zero blk size file.
I'm not sure why the file is getting created with zero blk size and
the reason for the below abend message.

could you please give your inputs on this ?

If you specify BLKSIZE=0 in the JCL .......... DON'T DO IT

Let the system determine the BLKSIZE for you, just code RECFM= and LRECL= and do not use DCB=(something, .................... ) either.

Hi All,

Thanks. Let me try the solutions suggested by you.

expat,

Hi, what is the difference between coding blksize=0 and not specifying a blksize at all? I thought (bad idea) that blksize=0 said 'let the system do it for you'? Or has that changed whilst I was delivering pizza and driving taxis? I have come acros, somewhere, a comment that in certain circumstances you do NOT let the system do it for you.

Agency interview next week, holiday in 2 hours! 26 of the next 100 hours will be spent in an aluminium tube - bliss

BLKSIZE=0 used to be the accepted method of telling the system to determine the BLKSIZE, but of course if the file was never opened it accepted BLKSIZE=0 and still does, and can cause problems - as above.

If the SMS environment is set up correctly then not specifying the BLKSIZE will let the system determine it and set it correctly.

BLKSIZE=0 also causes problems for us storage guys because HSM and the like will not process datasets with a BLKSIZE=0, except for scratching them at some future time.

Can be confusing for the ops support people as well, if they are looking for a backup of a dataset for a specific date and the backup doesn't exist because it had an invalid BLKSIZE and was bypassed by HSM, they start screaming at the storage guys and saying it's all our fault, which it isn't. Just try convincing them that it's their fault .......

Happy hols - just finished my interview

Of course, any well written program opens and closes it's datasets first/last thing
