Partition set definition

Partitions are defined by coding the macros DFHPSD (partition set definition) and DFHPDI (partition definition). Each partition definition must be part of a partition set definition.

DFHPSD

Each partition set definition contains a single DFHPSD macro followed by one or more DFHPDI macros, and ending with a partition set definition TYPE=FINAL.

Before CICS® can load a physical map, you must define a physical map using an RDO transaction with the MAPSET attribute.

An alternative to defining maps using RDO is to use the program autoinstall exit to create the definition when the map set is first used. (For programming information about the autoinstall user program, see Writing a program to control autoinstall of LUs.)

DFHPDI

A partition set contains one or more partitions. Each partition is defined by coding a partition definition macro.

Ending a partition set definition

A partition set definition ends with a macro of the form:

The PARTNSET name (if specified) must match that specified on the DFHPSD macro that started the partition set definition.
