Oracle Database can be configured in two basic ways: as a single instance (SI) database (non-cluster) or a Real Application Clusters (RAC) database. A single instance database has the Oracle software, database files, memory and processes all on one server. (link to database technical architecture diagram). Oracle RAC Architecture. Oracle’s RAC is heavily dependent on an efficient, high reliable high-speed private network called the interconnect, make sure when designing a RAC system that you get the best that you can afford. The table below describes the difference between a standard oracle database (single instance) and a RAC environment

The advantage of Oracle RAC is that resources on both nodes are used by the database, and each node uses its own memory and CPU. Information is shared between nodes through the interconnect—the virtual private network. Real Application Clusters provide high availability because of the failover of connections in the event of a hardware failure or server connection failure.

2 MPLEMENTING AN A REFERENCE ARCHITECTURE FOR I ORACLE RAC DATABASE ON ORACLE SERVERS, SWITCHES, AND SAN STORAGE HARDWARE A third objective is to outline the Oracle database workload testing and performance measurement environment. The environment we have used is based on freely available software. 2.8 Logical Architecture The following diagram describes the logical architecture of a two-node RAC on vSphere 5.0. The actual deployment uses four nodes. Figure 3. Logical Architecture of Two-Node Oracle RAC on vSphere Oracle RAC Architecture 10g and 11g Architecture Diagram: This is a basics architecture of Oracle RAC, We will discuss about new features/additions in 11g in each sections.

Oracle rac architecture diagram. "RAC Only" Architecture "RAC only" architecture uses Real Application Clusters and is an inherently high availability system.The clusters that are typical of RAC environments can provide continuous service for both planned and unplanned outages. RAC build higher levels of availability on top of the standard Oracle features. Hi, I will explain Architecture of Oracle RAC ( Real Application Cluster ) and What is the Oracle RAC in this article . In order to provide High Availability for Oracle database, Real Application Cluster (RAC) software was introduced in 2001 together with Oracle 9i. This diagram provides a roadmap for discussion. At a very high level, RAC architecture consists of these components: * Physical Nodes or Hosts. * Physical Interconnects and interconnect protocols. * Cluster Manager Software and Cluster Ready Services. * Oracle Instances and Cache Fusion. * Shared Disk System. Overview of Oracle RAC Architecture and Processing. At a minimum, Oracle RAC requires Oracle Clusterware software infrastructure to provide concurrent access to the same storage and the same set of data files from all nodes in the cluster, a communications protocol for enabling interprocess communication (IPC) across the nodes in the cluster ...
