This appendix describes the format of a listen address when the protocol between two machines is SNA LU0. It also gives you the protocol- and platform-specific information to set up connection data entries.

A listen address is a unique identifier used for interprocess communications. A Communications Server has two kinds of listen addresses. It uses one to receive messages from local processes and the other to receive messages from remote Communications Servers.
This section describes the format of the listen address used to receive messages from remote processes when the network protocol is SNA LU0.
Note: To view or change your instance's listen addresses, use the Configuration-By-Forms (cbf) utility or Configuration Manager (vcbf).
When you install Ingres Net on an MVS machine, the listen address is determined by the IGWFPSVR macro:
INSTALL = xx
TYPE=sna_lu0
ACB=acb_name
where:
Is the installation ID, found in II_INSTALLATION
Is the ACB name defined for the Ingres Net application using the VTAM APPL statement
In the APPL statement, you can specify the ACB name explicitly using the ACBNAME parameter, or implicitly by omitting ACBNAME. If you omit ACBNAME, the label on the APPL statement is used as the ACB name.
Connection Data Entry Information:
Protocol: sna_lu0
Network address: This parameter is ignored by MVS. Enter x.
Listen Address: lu_name
where:
Is the name of the LU that corresponds to the listen address specified on the server node. This name does not necessarily have to match the name specified as the configured listen address on the server instance.
If the server instance is on an MVS system, the lu_name is the application minor node name for the target Ingres Net installation. The application minor node name is usually, but not always, the ACB name.
