Parallel Sysplex® and OAM

OAM functions in a z/OS Parallel Sysplex. A Parallel Sysplex links many systems together and provides multisystem data sharing through the use of the cross-system coupling facility (XCF) component of z/OS. XCF services allow authorized applications on one system to communicate with applications on the same system or on other systems. XCF services also allow data to be shared between the applications on these systems. The system linking and multisystem data sharing makes the sysplex platform ideal for parallel processing. In a Parallel Sysplex, objects can be accessed from all instances of OAM and from optical hardware within the sysplex, and transactions can be processed more efficiently.
