Copy Services Collection Control dialog box
You use this dialog box to configure the data collection settings for the Copy Services feature.
The Copy Services Status feature is turned off by default. It is recommended that you first run a collection cycle off-hours to test how the feature may affect performance. Use the information from this test session to estimate the impact of collection on the address space of the Tivoli® Enterprise Monitoring Server and on the overall z/OS system. This estimate can help you choose optimal configuration settings, such as what time of day to start collection of data, what deadline (if any) to impose for completion of collection, and whether to include dataset-level attributes in the collection.
Details regarding the Collection Control dialog box
| Section/option | Comments |
|---|---|
| Collection Scheduling | |
| Start collection at (hh:mm) | Select this check box to activate most of the
other fields in the dialog box. hh is an integer from 1 to
12, and mm is an integer from 0 to 60. By default, collection is set to run daily. You deselect specific days of the week in the Every area to prevent collection on specific days. Start collection at causes the backend controller to schedule Summary Collection to begin at the specified time on the specified days of the week. If unchecked, Summary collection does not automatically run. |
| Stop collection at (hh:mm) | Use this setting to prevent data collection
from continuing into a time period when critical jobs run that require
significant amounts of system resources. You can also use this setting
to prevent collection when the Copy Services subsystem itself is in
heavy use and requires exclusive access to its CDS. hh is an
integer from 1 to 12, and mm is an integer from 0 to 60. If you specify a stop time and collection is halted because that time is reached, attributes and reports for every volume and dataset processed up to the point that collection was halted are available for viewing from the Tivoli Enterprise Portal. Stop collection at causes the backend controller to halt the Copy Services Summary Collection process at the indicated time of day. This response can be useful in environments where the Copy Services CDS is extremely large and the summary process interferes with normal Copy Services processing, or where a limit should be placed on the amount of elapsed time/resources consumed by the summary collection process. |
| Collection Options | |
| Summarize Copy Services dataset attributes | When you deselect this check box, no Copy Services
information is obtained for any tape dataset. You continue to see
a total dataset count, however, because this metric is obtained by
accumulating the total number of datasets on each processed volume. Note: By
deselecting this option, you reduce resource consumption and elapsed
time. However, several summary report workspaces are empty when you
do not collect this data, specifically, Job and Program summary.

| Collection Status | |
| Status message: Force Start button or Force Stop button | Status messages include, Collection
not active, Collection in progress, Collection
waiting, Collection failed, Collection
completed, Collection halted due to deadline,
and Collection halted by user or operator. Click Force
Start to manually force data collection to start. A Force Stop button
is available while data collection is running to manually force data
collection to stop. Results are displayed that include all volumes
and datasets processed up to the point that collection was halted.
And the status shown is If
you stop the collection by clicking on Force Stop button, the
state in the Collection Status area is |
