Automatic Erasure of Released Disk Space on an IBM 370 Computer Using the MVS Operating System

reportActive / Technical Report | Accession Number: ADA091957 | Open PDF

Abstract:

The standard MVS operating system supplied for use on IBM 370 computers does not erase or protect data residing on areas of disk that have been released for reuse. This report discusses the problem and describes efficient techniques that have been developed and installed at the DRCS which automatically erase all data when disk space is released by its owner. This has involved modifying the disk space management software and included some restructuring to eliminate contention for system resources while data is erased.
