GOAL:
What is LPAR?
FACT(s) (Environment):
OS/400 V4R2
FIX:
LPAR is an acronym for Logical Partitioning. Logical partitioning is the allocation of system resources in such a way to create systems that are contained in the same physical footprint but are logically separated from each other.
System resources include:
o Processors
o Main Storage (for example, memory)
o Interactive Performance
o System buses
o IOPs and their attached devices
Each partition operates as a complete system.
Each partition has its own:
o Address space
o Auxiliary Storage Pools (ASPs)
o Memory Pools
o Processors
o Problem Logs, LIC Logs, PAL entries, and so on
o Data (libraries, objects, file systems, and so on
o Performance characteristics
o Language feature code(s)
o SLIC, OS/400, and LPPs
o and so on
Software errors are isolated in each partition.
