Specific LU Name

If you want an MAI-OC session with a target application in which the MAI-OC LU name must be the name of a specific terminal, the MAILOGON LU= operand lets you specify the LU name that MAI-OC is to use.

This technique requires that you have knowledge of the terminal that is to be used on the session, but it also means that the identity of the terminal is predictable.

This facility is necessary to establish an MAI-OC session that has to have particular attributes, for example:

• An IMS system is generated with its IMS Master Terminal (primary operating console) having the LU name of MTO3767P.
• An operator is to operate an MAI-OC session from the OCS window of a terminal, with the MAI-OC session driving the IMS Master Terminal.
• The Operator requests the MAI-OC session with a MAILOGON command, specifying LU=MTO3767P on the command text. MAI-OC will open a VTAM ACB whose APPL name is MTO3767P and which must have been defined to VTAM as an APPL.

Note: An MAI Installation Exit (MAIEX02), if provided, is driven whenever a session request is processed. This exit may override the LU name or prefix, if required.
