Abstract
One of the offshoots of the increasingly competitive global business environment is growing pressure to reduce the number of outages, both of a planned and unplanned nature. In the area of planned outages, IBM has been steadily reducing the number of changes that require a system restart to implement. However, because of the detailed nature of these changes, many of them are not widely publicized and therefore not widely known.
This IBM Redbooks publication attempts to redress this situation by listing the changes that have been made to the operating system since OS/390 1.3.
