The configuration macro (EZACICD) is used to build the
configuration data set. This data set can then be incorporated into CICS® using resource definition
online (RDO) and can be modified using the configuration transactions
(see Customizing the configuration transaction (EZAC)). The macro is keyword
driven; the TYPE parameter controls the specific function request.
The data set contains one record for each instance of CICS that it supports, and one record for each
listener. The following is an example of the macros required to create
a configuration file for two instances of the CICS socket interface listeners each:
