Abstract
A DSM component is organized as a matrix of page. The data structure of a set of data structures occupies a column in the matrix of pages. A recovery file is maintained in a persistent storage. The recovery file consists of entries and each one of the entries corresponds to a column in the matrix of pages by a location of each one of the entries. The set of data structures is stored in the DSM component and in the persistent storage. Incorporated into each one of the plurality of entries in the recovery file is an indication if an associated column in the matrix of pages is assigned with the data structure of the set of data structures; and additionally incorporated into each one of the plurality of entries in the recovery file are identifying key properties of the data structure of the set of data structures.
