Non-Roll-Delete (NRD) Messages

A full NRD message, which can be displayed on more than one OCS window
concurrently, can be simultaneously purged from all the OCS windows on which it is
displayed.
The Central NRD Message Queue. All full NRD messages are held in a central NRD
message queue until they are deleted from both the queue and the OCS windows on
which they are displayed. If the number of messages in the queue exceeds the limit of
the queue, the oldest outstanding message is deleted from the queue and copies of the
message are removed from all OCS windows in which the message is displayed.
OCS operators with monitor-class status receive a warning when the central NRD
message queue is 75% full and when NRD messages are lost from the queue.
Issue a SHOW NRD command to display the NRD messages currently stored in the
central queue.
Displaying the Messages Held in the Central NRD Message Queue. When you enter OCS, you
must explicitly issue a NRDRET command to display all the NRD messages currently
in the central NRD message queue that are associated with your OCS window. It
might be a good idea to include a NRDRET command as one of the commands to
execute automatically when you enter OCS (see “Your OCS Operator Profile,” later in
this section).
NRD Messages With the OPER Attribute
A NRD message with the OPER attribute is a non-roll-delete message that is local to
an OCS window. It does not have a DOM ID assigned to it, and it is not stored in the
central NRD message queue.
When a NRD Message Is Displayed on an OCS Window
A NRD message is displayed on an OCS window:
If the NRD message is unsolicited, and the OCS window is profiled to receive the
unsolicited message. That is:
For monitor-class messages, PROFILE UNSOL=YES and PROFILE
MONMSG=YES
For EMS messages, PROFILE UNSOL=YES and PROFILE EMS=YES
For all other unsolicited NRD messages, PROFILE UNSOL=YES
For messages with a certain message code, the value of PROFILE MSGCODE
entitles the OCS window to receive messages with that message code
The default values of these PROFILE command operands are determined by your
user ID definition record. You can find out the default values by browsing to the
UMS : OCS Details panel in your user ID definition record. See Section 2, “User ID
Management Services (UMS),” for details.
If the NRD message is sent directly to the OCS window by an NCL procedure.
That is, the NCL procedure uses the WRITE verb to create a NRD message and to
specify the terminal to which to send the message.
