What is resource definition?
To run your system, you need to supply CICS with information
about your system resources, including software resources such as programs
and data, and hardware resources such as terminals, printers, and telecommunications
links. Many of the properties of these resources are variable, so you can
choose the particular functions and combinations of resources that your business
needs. Resource definition is the process by which you tell your CICS system
which resources to use, what their properties are, and how it can use them.
Resource definition installation
When a resource definition is installed, information about the
resources is used to construct the data structures that represent the resource
in the CICS address space.
