Abstract

A translation table entry contains a change recording override field for controlling whether a change bit is to be set on a store or not. Each 4K byte block of main storage has an associated storage key comprising a change bit. The change recording override field controls whether the change bit of the storage key associated with the desired 4K byte block of main storage is set to 1 for a store operation.
