Abstract
A fault occurs in a virtual environment that includes a base space, a first subspace, and a second subspace, each with a virtual address associated with content in auxiliary storage memory. The fault is resolved by copying the content from auxiliary storage to central storage memory and updating one or more base space dynamic address translation (DAT) tables, and not updating DAT tables of the first and second subspace. A subsequent fault at the first subspace virtual address is resolved by copying the base space DAT table information to the first subspace DAT tables and not updating the second subspace DAT tables. A fault occurring with association to the virtual address of the first subspace is resolved for the base space and the base space DAT table information is copied to the first subspace DAT tables, and the second subspace DAT tables are not updated.
