The ECHO Transaction

CA Gen provides a unique version of an ECHO transaction server for each server execution environment to which a Client Manager can connect (CICS, IMS, Windows Transaction Enabler, UNIX Transaction Enabler, and Tuxedo). The ECHO transactions do not test your generated applications. Rather, they are used in cooperation with the Client Manager to test the network connection between the client workstation and the execution environments that potentially host one or more target DPS applications.

The following activities must be completed prior to using the ECHO transaction server:

The Client Manager must be configured to use the target server that hosts the ECHO transaction server. See the chapter Configuring Client Manager Server Connections for information required to configure the Client Manager for server connections.
The ECHO server application must be installed and configured within the target server environment.

To test using ECHO, the CA Gen ECHO server must be installed and configured on the target server. Configuration requirements for ECHO depend on the platform on which you install the ECHO transaction.

The following table describes where to find a description of the ECHO application used in the various server execution environments to which a Client Manager can connect.

Target Server Execution Environment	Configuring the ECHO transaction
Windows or UNIX Transaction Enabler	When testing the connection to CA Gen Transaction Enabler target server environment, the ECHO transaction server is installed during the installation of the Implementation Toolset or Transaction Enabler CA Gen products. Note: See the Transaction Enabler User Guide for information about configuring to use the ECHO transaction server.
UNIX Tuxedo using CA Gen Tuxedo Proxy Client	When testing the connection to a Tuxedo execution environment and the communications type being used is TCP/IP, the ECHO transaction server is installed during the installation of the Implementation Toolset or Transaction Enabler CA Gen products. Note: See the Tuxedo User Guide for information about configuring a transaction server.
z/OS CICS	When testing LU6.2, TCP/IP, or ECI connections to the CICS target server environment, the ECHO transaction server is installed during the installation of the Implementation Toolset for z/OS product. The ECHO program is supplied in the CA Gen Load Library (ISPLLIB) provided with the Host Encyclopedia or z/OS IT software. Ensure the ECHO program is made available to CICS in the DFHRPL concatenation and that the relevant transaction and program definitions have been done. Note: For information about configuring to use the ECHO transaction server, see the z/OS Implementation Toolset Installation Guide or the Host Encyclopedia and Host Construction Installation Guide.
z/OS IMS	When testing LU6.2 or TCP/IP connections to z/OS IMS target server environments, the ECHOI transaction server is installed during the installation of the Implementation Toolset for z/OS product. The ECHOI program is supplied in the CA Gen Load Library (ISPLLIB) provided with the Host Encyclopedia or z/OS IT software. Ensure the ECHOI program is made available to an application IMS Load Library and that the relevant transaction and program definitions have been done. Note: For information about configuring to use the ECHO transaction server, see the z/OS Implementation Toolset Installation Guide or the Host Encyclopedia and Host Construction Installation Guide.
