Defining resources for intercommunication

There are a number of tasks required to set up your CICS system to enable communications with other systems.

Defining intercommunication resources
In an intercommunication environment, you create resources that define the links to other systems, and local definitions of remote resources.
Resource definition to enable data conversion
In order to convert data in CICS® Transaction Server for z/OS®, you must define some resources in your CICS region.
Where is data converted?
When CICS intercommunication uses SNA links, system data is transmitted in EBCDIC format. Therefore, ASCII-based systems convert all data except for application data areas, which are converted by the system that receives the data.
Avoiding data conversion
In many cases, you can design your applications to reduce the amount of data that is converted.
Types of conversion
The possible types of conversion are standard conversion, no conversion, and user-defined nonstandard conversion.
Defining the conversion table
You define the conversion table with DFHCNV resource definition macros.
