How to Install Oracle 10gR2 CRS Software

1. Login with VNC Viewer to Node 1 as Oracle User
2. CRS Software Location: /home/source/Oracle/software/crs/base/10.2.0/linux_64bit/clusterware
• > cd /home/source/Oracle/software/crs/base/10.2.0/linux_64bit/clusterware
3. Start OUI Installer
• csrv0dbxd11 | ORA1020 | /home/source/Oracle/software/crs/base/10.2.0.1/linux_64bit/clusterware
  > ./runInstaller
4. Choose Y when prompted if rootpre.sh has been run
5. At CRS Install Welcome Screen Click Next

• Notice the naming convention used:
• -ic = Interconnect or Private Network
• -vip = Virtual IP
10. On the Specify Network Interface Usage screen, change eth0 to Public
    
11. On the Specify Oracle Cluster Registry Location screen, Choose Normal Redundancy and enter the location to the OCR Disks.  You can run cat /etc/sysconfig/rawdevices to view what rawdevices are configured.
12. On the Specify Voting Disk Location screen, Make sure Normal Redundancy is checked and then enter the paths to the Voting Disks.
13. On the Summary Oracle Clusterware screen, review settings and then click Install.
14. CRS Install Progress
    
15. On the CRS Execute Configuration Scripts screen

17. To run Patch 4679769 which has been scripted in /export/home/oracle/ln.sh and run as root.
• See section 4.2.1.1 of Atlanta's Oracle Install Guide by Eddie Ambler
• [root@csrv0dbxd11 ~]# /export/home/oracle/ln.sh
18. To run script as root use sudo. Note, must run on both nodes.
• $ sudo /u00/app/oracle/oraInventory/orainstRoot.sh
  Changing permissions of /u00/app/oracle/oraInventory to 770.
  Changing groupname of /u00/app/oracle/oraInventory to dba.
