Potential Applications
The use of LPs allows multiple systems, including the I/O for the systems, to be
migrated to a single CPC while maintaining the I/O performance, recovery, and
multipathing capability of each system, and with minimum impact to the system
generation procedures.
LPs are suitable for consideration in the following environments:
Consolidation
Multiple production system images can be consolidated onto 1 CPC
without having to merge them into one image.
Migration Control programs or applications can be migrated by running the
old and new systems or applications in independent LPs that are
active on the same CPC at the same time.
Production and Test
Multiple production and test systems can run on the same CPC at
the same time.
Coupling Facility
A coupling facility enables high performance, high integrity data
sharing for those CPCs attached to it and configured in a sysplex.
Coupled Systems
Multiple instances of the same workload can be run in multiple LPs
on one or more CPCs as part of a sysplex configuration that takes
advantage of the centrally accessible, high performance data
sharing function provided by the coupling facility.
Extended Recovery Facility (XRF)
Primary and alternate XRF systems can run on 1 CPC. Multiple and
alternate XRF systems can run on 1 CPC.
Communications Management Configuration (CMC)
The communications management configuration (CMC) machine,
usually run on a separate CPC, can be run as an LP on the same
CPC.
Departmental Systems
Multiple applications can be isolated from one another by running
each in a separate LP.
Constrained Systems
Those systems that cannot fully use a large system because of
storage constraints can alleviate the problem by using LPs to define
multiple system images on the same CPC.
Diverse Workloads
Interactive workloads such as the Customer Information Control
System (CICS
®
) and time-sharing option (TSO) can be isolated by
running each in a separate LP.
