Batch processing is used for some of an organization’s most critical and time-sensitive business operations. It is used across many industries including, memo-posting of banking transactions in high volume, settlement and clearing, claims processing, risk assessments, payroll handling, ledger postings and reconciliations, and operational activities such as backups, reporting, data transfer, and archival. Batch jobs perform many read, write, and sort activities on sequential and VSAM files without manual intervention or input required unless, of course, a job does not end successfully. Batch window processing often takes place during off-hours or non-peak hours, and it is not unusual for OLTP to wait on the completion of the batch processing, as OLTP start of day (input) often requires the results of batch processing
