After the required CONNX CICS components are installed, they must be defined to the target CICS region. The CONNX installation automates the definition of CONNX CICS programs, files, and transactions to the target region RDO file. Depending on the CICS version and release installed on the target region, optional manual steps include updating the DCT (Destination Control Table), the PPT (Program Processing Table), and PCT (Program Control Table). If the CONNX load modules were linked into a new load library, then the final required manual step is to add the CONNX load library (default name = CONNX.CICS.LOAD) to the target CICS region startup JCL DFHRPL (Run Program List) DDNAME.
