Function: Abstracts the The cross-system extended services (XES) component of z/OS enables applications and subsystems to take advantage of the coupling facility. For instance, the system could receive the next instruction from memory as the current instruction is processed by the CPU’s arithmetic-logic unit (ALU). Concurrent use of shared resources can be a source of indeterminacy leading to issues such as deadlocks, and resource starvation. Learn more about Multicore vs Parallel Systems. system('a.
