IBM BladeCenter running Red Hat Enterprise Linux 5 and IBM System Storage DS4800 http://www.ibm.com/support/techdocs © Copyright 2010, IBM Corporation    Abstract The purpose of this paper is to assist those who are looking to implement Oracle Real  Application Clusters (RAC) on Red Hat Enterprise Linux 5 (RHEL5) running on IBM BladeCenter® servers and IBM System Storage™ products. The information provided herein is based on experiences with test environments at the IBM Oracle International Competency Center, and is based on available documentation from IBM, Oracle, and Red Hat. This paper does not cover the setting up of the shared disk for Oracle RAC. Prerequisites   Good knowledge of Oracle Database   Knowledge of the Linux® operating system Introduction This paper will discuss the necessary steps to prepare for and successfully install Red Hat Enterprise Linux 5 64-bit and Oracle Database 11 g Release 2   Enterprise Edition with Oracle Real Application Clusters 64-bit on IBM BladeCenter servers and IBM System Storage disks. The operating system environment described is the 2.6 kernel-based Red Hat Enterprise Linux 5 (RHEL5).  An implementation of Oracle Real Application Clusters 11 g   Release 2 consists of three main steps: Planning the hardware for Oracle Real Application Clusters implementation Configuring the servers and storage disk systems Installing and configuring the Oracle Clusterware and Oracle RAC database Oracle Database 11   Release 2 new features There are many new features found in Oracle Database 11 g Release 2. They can be found in Oracle 11 g Release 2 documentation available on the Oracle web site. According to Oracle Database New Features Guide 11g Release 2  , the main highlights are as follows: High Availability    Automatically repair corrupted blocks on the primary database or physical standby database (which must be in real-time query mode).    As part of Oracle Cloud Computing offering, databases can be backed up to Amazon S3.   With connection to a catalog and auxiliary database, DUPLICATE command in RMAN can be executed without any connection to the target database.   Tables with compression are supported in logical standby databases and Oracle LogMiner.    A primary database can support up to 30 standby databases.
