&SYS.NM.DID The &SYS.NM.DID system variable contains the value of the NonStop NET/MASTER
MS domain identifier. The PARAM DID command, which can be used only in the
configuration file, specifies a one-character through four-character domain identifier.
If PARAM ID is not specified, the first four characters of the NonStop NET/MASTER
Management Services (MS) system name (or ANON, for anonymous, if no system
name is specified) is used.
The domain identifier is used to identify a NonStop NET/MASTER MS system and
should be unique throughout all connected systems. It is also used as a prefix in
creating the user ID names to be used for the background environments. If a unique
value for the domain identifier is not selected, conflicting systems are not able to
initiate Remote Operator Control (ROC) sessions from background environments, and
Inter-System Routing (ISR) flows may not be set up.
&SYS.NM.DID
Considerations
Use the SHOW PARAM command to see the command setting of the NonStop
NET/MASTER MS domain identifier.
For a description of the PARAM DID command, refer to the NonStop
NET/MASTER MS Command Reference Manual.
