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 EntireX CICS Socket Listener
allows you to move workload from a mainframe environment to UNIX or Windows by replacing the RPC Server for CICS with an RPC Server for CICS Socket Listener running under UNIX or Windows
opens the CICS Container technology to the EntireX Adapter
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
Apart from installation there is no configuration necessary on mainframe platforms. All configuration data resides on the UNIX/Windows side. See:
Connection Parameters for CICS Socket Listener Connections in the EntireX Adapter documentation
Configuring an RPC Server Instance > CICS using the Command Central GUI | Command Line in the RPC Server for CICS Socket Listener documentation
The CICS Socket Listener is a subcomponent of the EntireX RPC Server for z/OS or z/VSE CICS®.
Under z/OS it is installed along with the RPC Server for CICS installation (job EXPINSTA in the JOBS data set). See Installing CICS Socket Listener in the z/OS Installation documentation for details.
Under z/VSE, execute job CICSDEF.J in sublibrary EXP960. See Installing CICS Socket Listener in the z/VSE Installation documentation for details.
Depending on your platform, more information on configuring the IBM standard listener for CICS can be found under the following IBM documentation:

To configure the IBM standard listener
Use the CICS-supplied transaction EZAC,ALT,LISTENER.
The PORT number corresponds to the configuration parameter CICS port.
See Connection Parameters for CICS Socket Listener Connections in the EntireX Adapter documentation and
Configuring an RPC Server Instance > CICS using the Command Central GUI | Command Line in the RPC Server for CICS Socket Listener documentation.
For SECEXIT, define EXXRFECS.
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.
