This
document explains the step by step process of installing Oracle 11g R1
(11.1.0.6) Clusterware Software.
Task List:
Setting Up oracle user
Environment
Running OUI (oracle Universal Installer) to
install 10g RAC Clusterware
Verify CRS status.
Verify Nodeapps status
Setting Up Oracle Environment:
Add the below lines into the .bash_profile under the oracle home directory to set the CRS_HOME in the
session.
export CRS_HOME=/u01/app/crs
Running OUI (Oracle Universal Installer) to install
Oracle Clusterware:
Complete the following steps to install Oracle
Clusterware on your cluster. You need to run the runInstaller from ONLY ONE
node (any single node in the cluster). Start the runInstaller
command as oracle user from any one node When OUI displays the Welcome page,
click Next
Xlib: connection to
":0.0" refused by server
Xlib: No protocol specified
Can't connect to X11 window server using ':0.0' as the value of the DISPLAY
variable.
If
you get the above error, please execute the below command as root and then
start the runInstaller by connecting as oracle.
[root@node1-pub ~]#
xhost +
access control disabled, clients can connect from any host
[root@node1-pub ~]# su - oracle
[oracle@node1-pub ~]$ /mnt/cdrom/runInstaller
At this step, you should not receive any error. If you have configured the
Pre-Installation steps correctly, then you will not get any errors. I get one
warning here as you can see which is complaining about the low memory than
required. I had only 512 MB ram and the required memory is 1GB but I would not
worry about this warning and will check the status box.
Check
whether the interface has correct subnet mask and type associated to it. If you
have configured the network for all the nodes correctly
Enter the filename and location (mount point) for
the OCR file. In the Pre-Instalation steps, I have configured ocfs2 for the OCR
files (/u02/oradata/ocr).
Use
the same mount point as OCR files and enter the filename you want for Voting
Disk file. If you choose the External Redundancy, then you need to mention only
one location.
The below commands can be used to verify the CRS status.
crsctl check crs <<-- for the local node
crsctl
check cluster <<-- for remote nodes in the cluster
[root@node1-pub ~]#
crsctl check crs
Cluster Synchronization Services appears healthy
Cluster Ready Services appears healthy
Event Manager appears healthy
[root@node1-pub ~]#
For the below command to run successfully, CSS needs to be running on the local
node.
[root@node1-pub ~]#
crsctl check cluster
node1-pub ONLINE
node2-pub ONLINE
Now,
verify that the nodeapps are configured and running by executing the below
command.
[oracle@node2-pub
dbs]$ crs_stat -t
Name
Type
