Method and apparatus for managing distribution of change-controlled data items in a distributed data processing system

摘要

A method and apparatus in a data processing system for managing distribution of data structures. A first data structure is received including a first version identifier. The version identifier is stored for the first data structure. A second structure is received including a second version identifier. Responsive to receiving a second data structure, a determination is made as to whether the second data structure is a replacement for the first data structure. Responsive to the second data structure being a replacement for the first data structure, a determination is made as to whether the first version identifier is different from the second version identifier. Responsive to a determination that the first version identifier is different from the second version identifier, the first data structure is replaced with the second data structure.
