Multiprocessor performance

Using MRO, you can take advantage of a multiprocessor by linking several CICS systems into a CICSplex, and allowing any terminal to access the transactions and data resources of any of the systems.

The system programmer can assign transactions and data resources to any of the connected systems to get optimum performance. Transaction routing presents the terminal user with a single system image; the user is not aware that more than one CICS system is present.

Transaction routing is described in CICS transaction routing.
