3) Execute runInstaller from the /stage/db directory and install Oracle Clusterware.
a) From a graphical terminal session on your first node, set the value of
ORACLE_BASE=/u01/app/oracle and execute /stage/db/runInstaller.
[oracle@vx0301 lesson1]$ export ORACLE_BASE=/u01/app/oracle [oracle@vx0301 lesson1]$ /stage/db/runInstaller
b) On the Select a Product to Install screen, choose Oracle Clusterware and click Next.
c) On the Specify Inventory directory and credentials page, ensure the inventory directory path is /u01/app/oraInventory and the operating system group name is oinstall. Click Next to continue.
d) On the Specify Home Details page, the Name should be OraCrs11g_home.
Do not accept the default location for the Path field. Enter /u01/crs11g in the Path field. Click Next.
e) The Product-Specific Prerequisite Page should check the minimum requirements and report no errors. Click Next to continue.

f) Enter the Cluster Name assigned to you by your instructor in the Cluster Name field on the Specify Cluster Configuration page. The only node appearing in the Cluster Nodes window is the installing (local) node. Click the Add button to add the second node in your cluster. Enter the Public Node Name, the Private Node Name, and the Virtual Host name, all in fully qualified format. Click OK to return to the Specify Cluster Configuration page. Review the name information for the second node and click Next.
g) On the Specify Network Interface Usage page, all network interfaces will be marked private. The proper interface type designations are: eth0-Public, eth1-Do Not Use, and eth2-Private. Select eth0 and click Edit. Change the interface type to Public and click OK. Next, select eth1 (the storage network), and click Edit.
Change the interface type to Do Not Use and click OK. Leave eth2 as the Private interface and click Next to continue.
h) On the Specify OCR Location page, select External Redundancy and enter /dev/sdb1 for the OCR location. Click Next when finished.
i) Select External Redundancy on the Specify Voting Disk Location page and enter /dev/sdb5 for the Voting Disk location and click Next.
j) Review the information on the Summary page and click Install. Monitor the progress on the Install page.
k) When the Execute Configuration scripts dialog box appears, open a terminal window to your local node and execute the
/u01/app/oraInventory/orainstRoot.sh script as root using the sudo command. When finished, ssh to the second node and run the
/u01/app/oraInventory/orainstRoot.sh as root. When finished, exit back to your first node in your terminal window.
[oracle@vx0301 ~]$ sudo /u01/app/oraInventory/orainstRoot.sh Changing permissions of /u01/app/oraInventory to 770.
Changing groupname of /u01/app/oraInventory to oinstall.
