12c AWR - Top 10 Foreground Events
Figure
6-5
provides the top 10 foreground wait events at the instance level and contains RAC-specific wait events.
AWR also provides a global level cache load profile, illustrating the global cache activity between the various instances
in the cluster. Figure
6-6
provides the overall workload characteristics on a RAC instance.

12c AWR - RAC Workload Characteristics
AWR is also organized into sections. When the AWR report is generated in a RAC environment, the second page of
this report relates to RAC. Apart from the performance data illustrated in Figure
6-5
and
6-6
, there is other important
data discussed later in this section. The various profiles are calculated using the formulas described in Table
6-2
.
