Abstract:
A method for providing a customer information control system (CICS) application programming interface (API), with global and local system and file control functions, in a data processing environment, the method comprising:implementing a loosely coupled CICS region in the data processing environment, the loosely coupled CICS region including at least two of a plurality of machines and their respective address spaces;allocating a flat segment in the address space of each of the at least two machines;providing a keeper in the address space of the at least two machines, one of the keepers being designated as a master keeper and the flat segment associated therewith being designated as a master flat segment;providing more than one CICS-API operating system server (COSS) within the loosely coupled CICS region, each COSS residing in one of the at least two address spaces within the loosely coupled CICS region; andproviding a suite of functions including the global and local system and file control functions in each COSS so that each COSS is capable of registering as a flat segment user and interfacing with a keeper and a master keeper, and so that each COSS is further capable of interfacing via the keeper with the master keeper in another of the at least two machines, each COSS being also capable of coordinated interaction with any other COSS within the loosely coupled CICS region, the suite of functions offering each COSS direct access to system and data resources from anywhere within the loosely coupled CICS region.
