Non-Roll-Delete (NRD)
Messages
Non-roll-delete (NRD) messages convey information that is of critical importance to
your installation. These messages do not roll by and disappear from your OCS
window. They remain displayed until you either delete or remove them from the
window, or the event that caused the message to be sent is resolved.
When a NRD message is delivered to an OCS window, it is initially displayed in the
roll-delete message area. It may be colored or highlighted, but there is no special
indication that it is a NRD message. When the roll-delete message area is full and a
NRD message is overwritten by another message, the NRD message currently
embedded in the roll-delete message area is redisplayed in the non-roll-delete message
area.
The non-roll-delete message area expands downward from the top of the window,
compressing the available space for roll-delete messages.
NRD messages are separated from the roll-delete message area by a non-roll-delete
delimiter line (by default a line of “=” characters).
Note You can change the non-roll-delete delimiter character by using the PROFILE NRDELCH command.
There are two types of NRD messages:
Full NRD messages
NRD messages with the OPER attribute
Full NRD Messages
A full NRD message is a non-roll-delete message that has a Delete Operator Message
Identifier (DOM ID) assigned to it when it is created. A DOM ID has the following
format:
domain-id/nrd-id
where
domain-id is the domain ID of the system from which the NRD message
originated, and
nrd-id is a unique number assigned by NonStop NET/MASTER MS.
The following is an example:
