2.3.2.1 Required Programs, CICS Definition Needed

You need to define 10 programs and one mapset to run CICS TCP/IP, or to provide supporting functions:

EZACIC00 is the connection manager program. It provides the enabling and disabling of CICS TCP/IP through the transactions EZAO and EZAP.

EZACIC01 is the task related user exit (TRUE).

EZACIC02 is the Listener program that is used by the transaction CSKL. This transaction is started when you enable CICS TCP/IP through the EZAO transaction.

| Note: While you do not need to use the IBM-supplied Listener, | you do need to provide a Listener function.

| EZACIC20 is the initialization/termination front-end module for CICS | sockets.

| EZACIC21 is the initialization module for CICS sockets.

| EZACIC22 is the termination module for CICS sockets.

| EZACIC23 is the primary module for the configuration transaction (EZAC).http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/EZAP1004/2.3.2.1?SHELF=&DT=19970730010745&CASE=[27/03/2012 13:30:42]


| EZACIC24 is the message delivery module for transactions EZAC and EZAO.

EZACIC25 is the Domain Name Server (DNS) cache module.

| EZACICME is the US English text delivery module.

EZACICM has all the maps used by the transactions that enable and disable CICS TCP/IP.

The following figures show sample RDO definitions of these programs.

Using Storage Protection: When running with CICS 3.3.0 on a storage-protection-enabled machine, all the required CICS TCP/IP programs (EZACIC00/01/02) must have EXECKEY=CICS as part of their CEDA definitions. The CICS/ESA 3.3 Release Guide contains more information on storage protection with TRUEs.

Figures 13, 14, and 15 show EZACIC00, EZACIC01, and EZACIC02 defined with EXECKEY(CICS). Note that, if the machine does not support storage protection or is not enabled for storage protection, EXECKEY(CICS) is ignored and does not cause an error.
