Installing 10gR2 Clusterware on Redhat 4.2 Advanced Server

A Brief Pep talk: Choosing a perfect Oracle
RAC configuration

We have done the preparation and gone about installing the
OCFS2 and ASM on our RHEL4.2 servers. Oracle RAC is growing in popularity and I
liked this
at Oracle myself. Here, you can get pre-tested, documented best
practices of installing Oracle on Linux based systems. In addition, some good
recommendations, from this
author on Infostor
, will help companies decide what to go for. I like the
quote in which he says that you can also deploy RAC on systems besides Linux
(which I will be documenting here as an ongoing effort to demo RAC on Solaris,
HP-UX and AIX servers as well).

Getting the Oracle RAC software

We have gone through this several times, but just to keep you
in the loop, go to Part
to get all the necessary software you need.

Now go ahead and unzip all the files, while logged on as an
“Oracle” user, into /tmp/orasoft directory (you are free to choose the
directory, I name it orasoft to avoid any confusion when looking for the

We are talking about these three files and will go ahead and
unzip them in the /tmp/orasoft folder

Extract the Clusterware package as follows:

# su - oracle
$ cd ~tmp/orasoft
$ unzip
$ unzip
$ unzip

OK now make sure that you are logged in as user “Oracle,” and have unset a
couple of parameters such as ORACLE_HOME, etc. and allow for xserver
connections for access from any console.

After being logged in as root, do the following:

# xhost +

Then logon as Oracle and follow the steps as detailed out in the print

Welcome screen, click next.

Specify inventory directory and credentials. We choose
/u01/app/oracle/oraInventory and specify “dba” as the operating system username.

Specify home details.

Product specific pre-requisite checks.

Add a new node: The primary node where you are running the
installer will be picked up by the installer and you will have to specify the
additional node(s) by clicking the “Add” button:

We will leave the cluster name as “crs”, you can however
choose a name that fits your installation template.

Your Ethernet interfaces are presented to you:

Specify the Oracle CRS location: Remember
we created three files, which we formatted with OCFS.

Specify Voting Disk Location:

You are presented with a summary. If all is satisfactory
click on install:
