Database Traits Console Command Summary
285
Choosing a value for a queue’s display lines trait depends on which is more important:
displaying as many stories as possible at one time, or showing a large portion of each story.
For instance, in a rundown queue it is important to display as many stories on the screen at a
time as possible, so the display lines trait is usually set to one line per story.
In queues where people often browse (such as those in the Wires directory), display a small
part of each story.
Stories in a queue display are usually separated by a blank line. The only exception is any
queue that displays one line per story, such as a rundown queue. Stories in these queues are
not separated from each other.
Type the display command to temporarily change the number of lines displayed per story for
a queue you are viewing. This change applies only to a single user’s workstation and lasts
only while the queue is being viewed.
Refresh
To set the queue refresh trait at the console, use:
dbtraits <queue name> [+refresh | -refresh]
To turn on this trait for a queue, use +refresh; to turn it off, use -refresh. For instance, to turn
on the refresh trait in RUNDOWNS.5PM, type:
dbtraits rundowns.5pm +refresh
Queues with refresh turned on display R in the preview lines column of list d output.
Use this trait only on important queues, like rundowns, that more than one person may
modify simultaneously. This allows everyone working on that rundown to immediately see
changes made by others.
n
To automatically refresh a queue, your system must spend a long time monitoring
workstations where users are viewing that queue. Using the refresh option on too many
queues simultaneously greatly increases the amount of work your system has to do and may
severely degrade its overall performance.
FTSindex Attribute
The iNEWS system supports up to 50 separate index bases for fast text searching. This
separation allows indexing of more documents while avoiding the index base file size limit
of 2GB. The index base is assigned using the dbtraits command and the ftsindex attribute.
