The Target LU Status page shows all the VTAM server applications that have been connected to Mainframe Access through SNA LU6.2 sessions
Target LUs for Mainframe Access Data Connect, IMS Option and CICS Option must be defined in the server configuration. DB2 LUs are not defined in the server configuration; all necessary connection information for DB2 is specified in the XDB Link configuration for SQL Option for DB2 and this connection information is provided to Mainframe Access with the first client request for a particular DB2 server.
The example shown in Figure 4-3 shows that sessions have been established with a Mainframe Access Data Connect server, a DB2 subsystem (on behalf of a SQL Option for DB2 client), an IMS system (on behalf of an IMS Option client) and a CICS system (on behalf of a CICS Option client). The example also shows that the internal LU for Password Expiration Manager functions, PEMDB62, has been accessed. This LU name will always show a status of "Not Active" because it is only used internally by Mainframe Access. The example also shows two CICS LU names with a status of "Not Active". The appearance of an LU name in the list indicates that it has been requested by a client and the status of "Not Active" may indicate that the associated subsystem is not up or that the connection attempt by Mainframe Access was rejected, possibly due to a configuration error in Mainframe Access or in the subsystem.
