LU name and netid

LU name and netid are used mostly for qualifying CICS®, DB2®, DDF, and IMS™ work. If you want to filter on the fully qualified name, you can use the LU name value of up to 8 characters, and then define a sub-rule of netid for up to 8 characters.

CICS
Only the LU name is available for CICS. It is the 8-byte NETNAME of the principal facility of the transaction instance. For details of the value of this parameter for non-VTAM terminals, and for transaction-routed transactions see CICS/ESA Performance Guide.
DB2
The LU name and netid associated with the originator of the query; for example, the LU name and netid from DDF. For more information about the format of the LU name, see DB2 SQL Reference.
DDF
The VTAM® LU name and netid of the system that issued the structured query language (SQL) request. For more information about the format of the LU name, see DB2 SQL Reference.
IMS
If a transaction comes in from an LU 6.2 device, you can specify both the LU name and the netid. Otherwise, you can specify only the 8 byte LU name.
NETV
The LU name and the netid associated with the NetView® subtask.
