The EntireX CICS Socket Listener is a remote connector on z/OS or z/VSE to call CICS mainframe programs. This document covers the following topics:
The CICS Socket Listener is used by the EntireX Adapter for CICS Socket Listener Connections. Apart from installation there is no configuration necessary in CICS. Configuration is done with the Adapter Connection. See Connection Parameters for CICS Socket Listener Connections in the EntireX Adapter documentation.
The implementation for CICS is based on the CICS standard listener provided by IBM. With this listener you can launch CICS transaction via TCP/IP. The launched transaction takes the TCP connection and continues the communication with the launching process.
Depending on your platform, more information on configuring the IBM standard listener for CICS can be found under the following IBM documentation:
z/OS Communications Server: IP CICS Socket Guide
z/VSE TCP/IP Support
The CICS Socket Listener is installed
together with the RPC Server for CICS, see Installing the RPC Server for CICS (z/OS | z/VSE), or
separately, see Installing CICS Socket Listener (z/OS | z/VSE)
Depending on your platform, more information on configuring the IBM standard listener for CICS can be found under the following IBM documentation:
z/OS Communications Server: IP CICS Socket Guide
z/VSE TCP/IP Support
To start/stop the IBM standard listener
Use the CICS supplied transaction EZAO. The listener is automatically started/stopped when CICS is started or stopped.
To configure the IBM standard listener
Use the CICS-supplied transaction EZAC,ALT,LISTENER.
For SECEXIT, define EXXRFECS.
Make sure the PORT number of the IBM standard listener corresponds to the configuration parameter Port.
