DASD sharing in DOS/VSE
Josef S. Ottmann · Software Practice and Experience · 1982
Abstract The first part of this report discusses DASD sharing in loosely‐coupled data processing systems. For the locking of shared files two design concepts are presented. The second part describes DASD sharing in the IBM operating system DOS/VSE. The control program routines which serialize the lock requests within one processing unit and the cross‐system locking facility are discussed.
