Hi all,

I have a great confusion plz read the contents below (red in color)
what is meant by same MVS systems complex (sysplex).
If it is different system then how we are using MRO instead of ISC.
And what is the differance between IRC(MRO) and ISC.



For CICS-to-CICS communication, CICS provides an interregion communication
facility that is independent of SNA access methods. This form of communication is
called multiregion operation (MRO). MRO can be used between CICS systems
that reside:
v In the same host operating system
v In the same MVS systems complex (sysplex).

Sysplex
A SYSPLEX is a collection of MVS systems that cooperate, using certain hardware and software products, to process work.

For MRO - isc
Although CICS/VS 1.4.1 was the latest product release to be delivered in 1979, the announcement of CICS/VS 1.5, to be delivered in 1980, created a high level of expectation among CICS users. CICS/VS 1.4 introduced Intersystem Communication (ISC) and the ability of CICS systems (OS and/or DOS) to interact with each other using VTAM. Applications on one CICS system could cause "function shipping" of a request to another ISC-connected system, accessing remote data or initiating remote transactions.

CICS/VS 1.5 was announced to provide Multi-Region Operation (MRO) by which multiple regions in CICS/OS/VS or partitions in CICS/DOS/VS could intercommunicate. The term "transaction routing" was now added to the CICS vocabulary. MRO enabled the user to distribute the CICS workload across multiple CICS regions, providing benefits such as virtual storage constraint relief (VSCR), better multiprocessor utilization or simply separation of test and production systems. Customers became anxious awaiting delivery of 1.5 planned for 1980.
