ORACLE RAC TRAINING

About ORACLE RAC

Oracle RAC (Real Application Clusters) is a database or set of databases that are clustered on a set of servers using Oracle supplied software called Oracle Clusterware. Oracle RAC was first introduced with Oracle 9i. An Oracle RAC cluster can have up to 100 instances and each Oracle instance usually runs on a separate server. At its simplest, Oracle RAC is a single database that is accessed and shared by several Oracle instances running on separate servers as shown below.

Oracle RAC Architecture Basic

Since all instances in a RAC access the same database, the overall system must guarantee data integrity so that a computer always retrieves the current version of any data even it it was just updated by another instance in the cluster

A RAC System, by providing multiple instances (i.e., hosts and its associated resources) access the same database, creates multiple database computing centers and extends high availability and scalability.

The major components of a Oracle RAC system are

  • Shared disk system
  • Oracle Clusterware
  • Cluster Interconnects
  • Oracle Kernel Components

Benefits of Real Application Clusters (RAC)

  • Ability to spread CPU load across multiple servers
  • Continuous Availability / High Availability (HA)
  • Protection from single instance failures
  • RAC can take advantage of larger SGA sizes than can be accommodated by a single instance commodity server
  • Scalability that is more useful in long term applications
  • Protection from single server failures
  • RAC has offer less downtime for OS/DB upgrade and instance level failure
