Policy Details The Policy Details tab, shown in Figure 5-13, is where a DBA can view
the global policies applied to a selected deployed data-tier application. The Policy
Details tab can also be used to create a custom policy that overrides the default global
policy applied to a deployed data-tier application. For example, by expanding the
Data-Tier Application CPU Utilization Policies section, you can observe that the global
policy is applied. With this policy, a CPU of a data-tier application is considered to be
overutilized when its usage is greater than 70 percent and underutilized when it is less
than zero percent. If you wanted to override this global policy for a data-tier applica-
tion, you would select the Override The Global Policy option button and specify the
new overutilized and underutilized numeric values in the box. You would then click
Apply to enforce the new policy. In Figure 5-13, the global policy has been modied
from its original settings, and the CPU of a data-tier application is now considered to
be overutilized when its usage is greater than 30 percent. To override this setting, you
would choose the Override The Global Policy option button and set a desired value
in the box to the right of the policy description. For this example, the setting was
changed from 30 percent to 70 percent.
