Extra information for Spotlight on Oracle RAC

Within Spotlight on Oracle RAC the rules that govern alarms are complicated by the fact that Spotlight is diagnosing the operation of a cluster of database instances as well as the overall behavior of the cluster itself.

Perhaps Spotlight has inhibited the alarm because it has not met a secondary criterion. One such criterion is that of "low load", where a cluster element is essentially idle.

This is an important consideration, for example, when the Balance gauge on the Instance Panels shows an imbalance without raising an alarm. Even though one database instance has a higher workload than others in the cluster, Spotlight has determined that the overall workload on the cluster is too low for the imbalance to be a problem.

For more information on this, see Cluster | Balance Page.
