Abstract:
1. A method for accessing data stores, the method comprising: establishing communications between a first control module and a first connection module, wherein the first control module is configured to access a plurality of data stores in a single management structure of a mainframe coupling facility through a control block of a mainframe Cross System Operating System having a single physical communication channel limiting the first control module to communication with a single connection module, the single management structure comprising a cache structure within the coupling facility, each data store configured to communicate with a mainframe data processing system through a single physical communication channel; establishing communications between the first connection module and a first association module in communication with a first data store of a plurality of data stores of the single management structure wherein the first connection module comprises a single physical connection from the first control module, to the first connection module, and then to the coupling facility and wherein the first association module comprises a linked array mapping data addresses into the first data store, and the first control module accesses the first data store exclusively through the a single physical connection, the first connection module directly physically connected exclusively to the first association module; and establishing communications between the first association module and a second association module in communication with a second data store, wherein the first control module accesses the second data store exclusively through the first connection module, the first association module, and the second association module in a series connection.
