TECHNICAL FIELD
This invention relates, in general, to data processing within a distributed computing environment, and in particular, to the duplexing of structures, such as structures of one or more coupling facilities.
BACKGROUND OF THE INVENTION
Some distributed computing environments, such as Parallel Sysplexes, today provide a non-volatile shared storage device called the coupling facility, that includes multiple storage structures of either the cache or list type. These structures provide unique functions for the operating system and middleware products employed for the efficient operation of a Parallel Sysplex. For example, the cache structures provide directory structures and cross-invalidation mechanisms to maintain buffer coherency for multisystem databases, as well as a fast wr
