Oracle 12c (12.1.0.2) GI Cluster Installation (ASMFD): Linux

<- Legacy

Overview

What follows is the most common way to install the Oracle 12c Grid Infrastructure (GI) for Linux enterprise environments.

Prerequisites

• You have performed the LINUX OS Prerequisites.
• You have configured ASMFD, performed a base GI install and applied the latest patches on all nodes. If not go here.

Cluster Installation

• Log into GUI as the grid user.
• Ensure other initial nodes are up and can ping and nslookup each other.
• Ensure all potential nodes can see the ASMFD configured disks:
  root> $ORACLE_HOME/bin/asmcmd afd_scan
  root> $ORACLE_HOME/bin/asmcmd afd_lsdsk
• You can monitor the process of the root scripts watching the alert log. Example:
  tail -f /u01/app/grid/diag/crs/rac02/crs/trace/alert.log

Procedure

Run Cluster Configuration Assistant:

  grid> /u01/app/12.1.0.2/grid/crs/config/config.sh

Installation Option

 (x) Configure Oracle GI for a Cluster

Cluster Type

 (x) Configure a Standard cluster

Grid Plug and Play

 Cluster Name: rac-cluster
 SCAN Name:    rac-scan
 SCAN Port :   1521
 [ ] Configure GNS

Cluster Node Information Should see current system. Example: rac01 | rac01-vip

 [Add]
 Public Hostname:  rac02.localdomain
 Virtual Hostname: rac02-vip.localdomain
 [SSH connectivity]
    OS Username: grid 
    OS PW:       ********
 [Setup] ...
    Msg displayed: 
    "Successfully established passwordless SSH connectivity between the selected nodes."
 [Test] ... Shows OK (already established)
 [Next] ... Verification process runs for a moment

Network Interface Usage

 192.168.56.0  = Public  (pubnet)
 192.168.10.0  = Private (privnet)

Storage Option

 (x) Use standard ASM for storage

ASM Disk Group

 (x) Create a new Disk Group

Create a new Disk Group

 Disk group name: GRID

 Select Redundancy & Disks for Group:
   Generally use:
     (x) Normal   = if needing ASM based redundancy.
     (x) External = if not needing ASM based redundancy.
 Allocation Unit Size = 1mb

 Add Disks  
   [ ] AFD:DATA   
   [ ] AFD:FRA      
   [x] AFD:GRID  <= Just select disks to be used for the GI (+GRID).
   Other disks (for +FRA, +DATA...) can be added later.

ASM Password

  (x) Use same passwords for these accounts.

Failure Isolation

  (x) Do not use Intelligent Platform Management Interface (IPMI)

Management Options

  [ ] Register with Enterprise Manager (EM) Cloud Control

Root script execution

  [ ] Automatically run configuration scripts
    Disabling this makes it easier to debug.

Prerequisites Check

  Fix any issues then return to this point.
  If everything acceptable then [Next]

Summary

 [Install]
 Process runs... 
 [Close] when completed.

Create grid BASH User Profile (.bashrc)

Uncomment ORACLE_SID entry setting it to the ASM instance name on this system (ASM1, ASM2 ...).

umask 022

# Get the aliases and functions (if .bash_profile)
#if [ -f ~/.bashrc ]; then
#	. ~/.bashrc
#fi

# Global Definitions
if [ -f /etc/bashrc ]; then
   . /etc/bashrc
fi

if [ $USER = "oracle" ] || [ $USER = "grid" ]; then
   if [ $SHELL = "/bin/ksh" ]; then
      ulimit -p 16384
      ulimit -n 65536
   else
      ulimit -u 16384 -n 65536
   fi
   umask 022
