Qualifying network LU names
You can use the same name for LUs on different systems by adding the network identifier. This eliminates the need to have unique names for every LU on every system in your complex. You can use the network-qualified LU name as the name of the partner LU to allocate remote LU 6.2 conversations and sessions.
A network-qualified LU name consists of a one- to eight-character network identifier of the originating system, followed by a period and the LU name. A network-qualified LU name must be enclosed in single quotes for commands.
Example: /DISPLAY
LUNAME'NETID1.LUAPPC2'
Use a network-qualified LU name when transmitting data to a remote destination. If no network identifier is present, IMS allows z/OS® to determine the destination.
The parameter ALL for either the network identifier or the LU name cannot be substituted in a network-qualified LU name in commands.
Example: /DISPLAY
LUNAME'NETID1.ALL'
The LU name in the LU 6.2 descriptor
can be network qualified. The network-qualified LU name is optional
on commands that support the LUNAME keyword.
APPC/MVS™ uses the name of LU 6.2 network-qualified LUs to allocate conversations. APPC/MVS strips off the network ID and passes the 8-byte LU name to VTAM®. Without APPC/MVS support for network-qualified names, the LU name must be unique for the different networks.
The ALL parameter for either the
network identifier or the LU name cannot be substituted in a network-qualified
LU name in a command.
The LU name in the LU 6.2 descriptor can be network qualified.
