Oracle RAC Statistics and Events in AWR and Statspack Reports

The statistics snapshots generated by AWR and Statspack can be evaluated by producing reports displaying summary data such as load and cluster profiles based on regular statistics and wait events gathered on each instance.

Most of the relevant data is summarized on the Oracle RAC Statistics Page. This information includes:

• Global cache load profile

• Global cache efficiency percentages—workload characteristics

• Global cache and Enqueue Service (GES)—messaging statistics

Additional Oracle RAC sections appear later in the report:

• Global enqueue statistics

• Global CR statistics

• Global CURRENT served statistics

• Global cache transfer statistics.
