The LPAR (Logical Partitions) feature in an IBM mainframe allows a site to divide its mainframe into "partitions" and run multiple operating systems in parallel.
For our purposes, we can treat each partition as a standalone mainframe computer and we can treat the processor complex as a type of "multi-CPU configuration."
To determine how Control‑M controls the production work in two logical partitions, we need to determine what connection (if any) exists between the two partitions. Relevant connections are: shared SPOOL, shared-DASD only, and NJE.
If an MVS system runs in both partitions and the only connection between them is shared-DASD, then the description under Multi-CPU Configuration With Shared-DASD Only also applies to this configuration.
In addition, these considerations apply to other supported CPUs with hardware partitioning capabilities, which can be operated in either "single image mode" or "partition mode."
