Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In IBM mainframes, BatchPipes is a batch job processing utility designed for the MVS/ESA operating system, and all later incarnations-OS/390 and z/OS. In traditional processing, if data records are written out to sequential (QSAM and BSAM) data set on disk or tape, they cannot be at the same time read back in by another job. Hence, these two jobs-"writer" and "reader"-cannot run at the same time. This is termed file-level interlock or data-set-level interlock. With BatchPipes an installation can arrange for the data to be "piped" between the two jobs. The advantage is that the jobs can run concurrently and it is possible, and very usual, to avoid the time to write the data to secondary storage and to read it back. The combination of these two characteristics, if used judiciously, leads to a reduction in the combined elapsed time of the two jobs, as measured from the start of the writer job to the end of the reader job.
