One of the
best features of Oracle 10g RAC is
Services. With
Services, client connections can be
divided into logical connection
targets. These targets can be any
combination of nodes on the cluster
with specific failover practices
applied. In addition, Services can
use Resource Manager Plans (not
related to the DRM feature from the
previous Finding). With
Resource Manager Plans,
connections can be throttled in
terms of CPU usage, parallelization,
UNDO space, and other features.
There are also highly complex
possibilities, such as query
estimation and throttling based on
estimated time.
