Using the SCHEDULER
QUEUE SAMPLES Screen
The SCHEDULER QUEUE SAMPLES screen initially displays the four most recent
queue samples collected by TSAMPLE for the READY queue. You can select any of
the other queues by placing the cursor next to the queue name and pressing F1 for the
Sample Queue function. The Queue field in the top left corner of the screen shows the
name of the queue currently displayed.
The most recent number of queue entries for each of the queues is shown down the
right side of the screen, under the Current Totals heading.
Each screen displays up to four sets of sample counts for each applicable type of work.
The most recent sample data in the set appears in the left column, with the oldest
sample data in the set displayed in the right sample data column. The Sample Taken
column headers give the year, month, and day of the sample, followed by the time in
24-hour format, indicating when the sample was collected.
You can retrieve different sets of sample data for the queue by pressing Latest Sample
(SF4), which gets you the most recent set of sample data; Later Sample (F4); and Earlier
Sample (F5). Because records are kept in reverse chronological order, F5 moves you
backward in time to earlier data and F4 moves you forward in time to more recent
data.
Interpreting the Numbers Each individual count is represented as a nine-digit number, with zeros suppressed.
For types of work that are not applicable to the current queue, the corresponding
count fields are blank. If a value displayed in a count field meets or exceeds a
configured threshold maximum value for the corresponding type of work and queue,
the field is highlighted.
Consider the following as you interpret the numbers on the SCHEDULER QUEUE
SAMPLES screen:
Lower-priority items in a queue accumulate while higher-priority items are being
serviced. For example, counts for Delete Item, Unsave Item, and End Session work
increase during the day while other higher-priority work requests, such as Submit
Package, are serviced.
If lower-priority items accumulate without being serviced, you can configure a
cleanup TAREQ, as explained in Section 11. If higher-priority items accumulate
and are not serviced fast enough, you might need to configure more TAREQs,
TWORKs, and TISERV-ASYNCs.
Counts for work in the READY queue include any HELD records found within the
queue.
A zero for the TIME queue Current Total indicates either that no entries were
found in the TIME queue when the most recent sample was taken or that TIME
queue sampling was disabled. (The end of this section tells you how to configure
the TSAMPLE server.)
If no sample counts exist for the TIME queue when you press F1 to get a sample
queue, the warning message "No TIME Queue sample available" appears on the
advice line.
