Abstract:
A method for implementing a customer information control system (CICS) application programming interface (API), with transient data queue functions, in a data processing environment, the method comprising the steps of: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; providing at least one CICS-API operating system server (COSS) within the loosely coupled CICS region, each COSS operating in one of the at least two address spaces within the loosely coupled CICS region; providing an information resource within the loosely coupled CICS region, the information resource including a file for holding a transient data queue; and providing a suite of functions including the transient data queue functions in each COSS, each COSS being capable of coordinated interaction with any other COSS within the loosely coupled CICS region, and each COSS being able to directly access the transient data queue from anywhere in the loosely coupled CICS region irrespective of which address space the COSS is operating in, wherein there is no affinity between the address space in which each COSS is operating and the address space being occupied by the transient data queue, and wherein the information resource is shared by each COSS.
