9.
Choose whether the configuration is to be currently active (true/false). This switch allows you
to turn the optimization off and on as required.
10. When done, click Submit Query. An alert window appears confirming that Adaptive
Optimization configuration has been added.
11. Click OK to return to the Sampling Policies window.
Changing an Adaptive Optimization Configuration
To change an Adaptive Optimization configuration:
1.
From the Adaptive Optimization Configuration window, click Change next to the configuration
that you want to change.
The Change Adaptive Optimization Configuration window appears.
2.
Make the necessary changes.
3.
When done, click Submit Query. An alert window appears confirming that the Adaptive
Optimization has been changed.
4.
Click OK to return to the Sampling Policies window.
Removing an Adaptive Optimization Configuration
To remove an Adaptive Optimization configuration:
1.
From the Adaptive Optimization Configuration window, click Remove Adaptive Optimization.
The Remove Adaptive Optimization Configuration window appears.
2.
Choose the configuration to remove from the pull-down menu based on tiers that are defined.
3.
When done, click Submit Query. An alert window appears confirming that the Adaptive
Optimization has been removed.
4.
Click OK to return to the Sampling Policies window.
NOTE:
When removing a CPG (tier) associated with an Adaptive Optimization configuration,
the VV data remains on that tier. If you want to remove a tier, you should first make sure that
there is no VV data on the tier. To do so, set the space limit for that tier to 0. Adaptive
Optimization will, over time (it may require multiple iterations), move the data to the other
tiers. Once that CPG has no used space, you can then safely remove or change that CPG.
Adaptive Optimization Reports
System Reporter provides three types of Adaptive Optimization reports as follows:
•
Region IO Density -- Show the I/O access rate and distribution of data for each tier.
•
VV Tiers -- Shows the distribution of space in each VV among the tiers in absolute terms and
also as a percentage.
•
Space Moved -- Shows the space moved over a selected time interval.
You can access these reports through the System Reporter Main Menu by clicking on the Custom
Reports tab and then selecting the Adaptive Optimization report.
NOTE:
See
“Adaptive Optimization Reports” (page 112)
for details on interpreting an Adaptive
Optimization report.
Region IO Density Report
The Region IO Density report for an Adaptive Optimization configuration, shows three charts. The
first two charts (
and
) show histograms with the X-axis
(category) illustrating the IO access rate.
