Issue/Introduction

Description:

BatchPipes are integrated into a larger IBM product: SmartBatch.

With BatchPipes an installation can arrange for the data to be "piped" between two jobs as opposed to traditional processing where files cannot be at the same time read back in by another job. Hence, two jobs-"writer" and "reader"-can run at the same time with BatchPipes.

When using this feature, DBUTLTY BACKUPONLY fails with ASFP327I and S913(74).

Solution:

MVS changed its logic internally when calculating the actual block sizes for BLKSIZE=0 piped datasets or when the BLKSIZE is not specified. This leads to Block Size discrepancies between the writer and reader DCBs.

All DCB parameters should be specified for the "pipe" when executing parallel reorganizations utility, e.g.:

DCB=(RECFM=VB,BLKSIZE=32000,LRECL=999)
