It doesn't. The Oracle Grid is clustered, low cost, hardware and storage
components being intelligently shared to execute one or more workloads,
with higher availability ( and other measure of QoS). RAC is used to
cluster the database machines together, ASM is used to help manage the
shared storage, Application Server can farm out the application logic
which is integrated via BPEL and other cool App Server wonderfulness,
and Grid Control provides a management stack that can provision each
layer horizontally, but also measure and manage service levels for
specific workloads up and down the stack.
