The EZASOKET configuration file (EZACONFG) contains details of CICS regions (that is, enterprise servers capable of running CICS applications) and the CICS listeners within those regions. The file can be shared by multiple enterprise servers. The location of the file used by your enterprise server is governed by the File Path configuration setting for the server.
For each CICS region that supports EZASOKET and is controlled by the configuration file, there is an associated object (referred to as a CICS object) in the configuration file. The object is identified by the APPLID of the CICS region. There is also a listener object for each listener defined for a CICS region.
The first task you will perform is to use the EZAC transaction to define a CICS object in the configuration file for your CICS region/enterprise server. If the configuration file does not exist, EZAC will create it.
