Roll-Delete Messages

There are two major classifications of messages displayed in the message display area:
Roll-delete messages convey information that is not of immediate critical
importance to your installation.
Non-roll-delete (NRD) messages convey information that is of critical importance
to your installation.
By default, when non-roll-delete messages are not present, the roll-delete message
area occupies the entire window space between the title line and information line.
As non-roll-delete messages appear, the non-roll-delete message area expands
downward from the top of the window, compressing the available space for roll-delete
messages until only the minimum roll-delete message area remains.
NonStop NET/MASTER MS requires that there always be at least one line of roll-
delete message space available.
Note You can change the minimum size of the roll-delete message area by using the PROFILE RDMIN
command.
Both roll-delete and non-roll-delete messages are also recorded in the activity log. You
can view them at any time by entering the Activity Log Browse facility. You can
access the Activity Log Browse facility by pressing the F7 (PF07) function key. See
Section 6, “Examining the Activity Log,” for more information on the Activity Log
Browse facility.
Roll-Delete Messages Most messages displayed in your OCS window are classified as roll-delete messages.
Typically, such messages are not of critical importance to your installation. These
messages might be the response to a NonStop NET/MASTER MS command, a report
that a user has logged on, or a report that a terminal has been opened.
Roll-delete messages are written line by line from the top to the bottom of the roll-
delete message display area.
By default, when the roll-delete message display area is full, the flow of incoming
messages pauses for a specified number of seconds (roll-time delay interval) and then
wraps to the top of the window again, overwriting the oldest displayed messages. If,
however, NonStop NET/MASTER MS determines that later messages will wrap past
the line on which the first message in the group is displayed, the message display
freezes and the holding-mode message
AUTO HOLD
appears in the information line. Press the ENTER key to continue the message display.
(This assumes the default AUTOHOLD setting of AUTO; see Table 4-1 for more
information.)
The roll-delete delimiter line (by default a line of “-” characters) separates the most
recent messages from the earlier messages.
