How to Install 11gR2 RAC linux for oracle apps r12.2.0

  1. 1. 11gR2.0.4, 3 Node RAC on Linux 6.5 for Oracle APPS R12.2.2 By GowraInfosys 3 Node Oracle RAC 11gR2.0.4, Linux 6.5 on Oracle private Cloud, vMotion Fixed VIP, Fixed SCAN, Fixed Public, Fixed Interconnect Network, Prepared for Oracle Apps R12.2.2 contact@gowrainfosys.com
  2. 2. Welcome and Introduction contact@gowrainfosys.com  Introduction  How to install and configure Oracle RAC 11gR2.0.4 on Linux 6.5 on Oracle Private Cloud with , Fixed VIP, Fixed SCAN, Fixed Public, Fixed Interconnect Network  Only Grid Infrastructure is installed Preparation for Oracle Apps R12.2.2  GNS is not used in this configuration.  Oracle RAC 11g release 2 (11.2) introduces the Single Client Access Name (SCAN). The SCAN is a single name that resolves to three IP addresses in the public network.  When using Grid Naming Services(GNS) and Dynamic Host Configuration Protocol(DHCP), Oracle Clusterware configures the Virtual addresses for the SCAN name that is provided during cluster configuration.
  3. 3. Overview contact@gowrainfosys.com  The node VIP and the three SCAN VIPs are NOT obtained from the DHCP server  If a new server joins the cluster, then Oracle Clusterware does NOT dynamically obtains the required VIP address from the DHCP server, Need to configure Manually.  We define these address in the DNS domain before installation. Optionally in /etc/hosts  Fixed Private interconnects are configure in /etc/hosts, two routes are used for interconnect, this was introduced from 11gR2 on wards.  SCAN needed to be configured in DNS to resolve to 3 (three) IP address in DNS.  In this presentation we will install and configure the Real Application Cluster(RAC) without Grid Naming Service(GNS), Oracle 11.1 on Linux 6.511.
  4. 4. Vocabulary contact@gowrainfosys.com  This document is divided into Three major sections ◦ Pre-Installation Steps ◦ Installation Steps ◦ Post-Installation Steps  Pre-Installation steps deals with the configuration of the O/S for installation of the Oracle software. Installation section deals with the installation of the Grid Infrastructure Oracle Server and ASM.  Post-Installation Steps are not covered, I will be part of Oracle Apps R12.2 installation with RAC, Multi Node configuration.

  6. 6. contact@gowrainfosys.com  Prerequisites ◦ Shared storage such as SAN Openfiler or Data ONTAP Simulator. ◦ iSCSI software is already configured. Lun’s are presented to the Virtual Machines. ◦ RAC and Oracle Apps R12.2.2 certified OS has been installed on the RAC nodes. In this document I will be using the Linux 6.5 x86_64bit with latest OS patches. ◦ BASH is the default shell for the root, oracle and grid user. ◦ Interconnect NIC has configured with fixed private address on all RAC nodes.
  7. 7. contact@gowrainfosys.com  Pre-Installation Steps ◦ Configure the Domain Name System(DNS) ◦ Configure the /etc/hosts file on the RAC Nodes ◦ Space requirement on the RAC Nodes ◦ Setup the O/S users and groups ◦ Setup the ulimit for grid and oracle User ◦ Setup the /etc/profile file ◦ Setup the /etc/hosts file ◦ Setup the environment variable ◦ Setup the kernel parameters ◦ Setup the Network Time Protocol(NTP) ◦ Install the O/S packages ◦ Enable the Name Service Cache Daemon ◦ Configure SSH equivalence
  8. 8. contact@gowrainfosys.com  Installation Steps ◦ Download the Software and verify using md5sum ◦ Install the Grid infrastructure for Cluster ◦ Install the Oracle Server with RAC option  Post Installation Steps ◦ Not covered in this presentation ◦ Please, see the Multimode Oracle Apps R12.2 installation and configuration
