Some database features are also integrated with Oracle Streams, Advanced Queuing to achieve queue location transparencyand Oracle Scheduler to map services to specific job classes. Windows clusters use the TCP protocol.
Automatic Storage Management provides the infrastructure for a storage grid. The LMS process also controls the flow of messages to remote instances and manages global data focumentation access and transmits block images between the buffer caches of different instances. For availability reasons, the data must be located at both sites, thus requiring the implementation of disk mirroring technology for storage.
This includes providing the highest availability for database connections, rapid failure recovery, and balancing workloads optimally across the active configuration. Data Guard Concepts and Administration. If your application performs well on a noncluster Oracle database, then it will perform well in an Oracle RAC environment.

Oracle Dlcumentation uses Oracle Clusterware for the infrastructure to bind multiple servers so they operate as a single system. This is especially true if your environment requires scalability across a greater number of CPUs.
Also, note the following recommendations about monitoring Oracle RAC environments: Oracle Clusterware manages the allocation of nodes to run the instances and Oracle RAC allocates the required redo threads and undo tablespaces, as needed.
Oracle cloning copies images of the software to other nodes that have similar hardware and software. Documentation on this page describes how to manage Documenntation Clusterware and Oracle Real Applications Clusters deployments.

Real Application Clusters Administration and Deployment Guide - Contents
Oracle Clusterware attempts to keep the required number of servers in the server pool and, therefore, the required number of instances of the Oracle RAC database.
For example, to run Oracle9 i and Oracle Database 10 g in the same cluster:. This chapter includes the following topics: With SCAN, you are no longer required to modify your clients when changes occur to the cluster configuration.
