While trying to install 11gR1 on Oracle Enterprise Linux (OEL5), runInstaller failed for unixODBC* packages. To solve the issue , I started following OTN article

http://www.oracle.com/technology/pub/articles/smiley-11gr1-install.html

When trying to install RPM from CD3, faced following errors for unixODBC* rpm

#rpm -ivh compat-libstdc++-33* libaio-devel* sysstat* unixODBC*
warning: compat-libstdc++-33-3.2.3-61.i386.rpm: Header V3 DSA signature: NOKEY, key ID 1e5e0159

unixODBC = 2.2.11-7.1 is needed by unixODBC-kde-2.2.11-7.1.i386

Issue is because of missing rpm unixODBC-2.2.11-7.1.i386.rpm which is present in CD2 . Install it first and then the other RPM i.e
unixODBC-devel-2.2.11-7.1.i386 and unixODBC-kde-2.2.11-7.1.i386 can be installed without errors

Mount CD2
#cd /media/E*/Server
#rpm -ivh unixODBC-2.2.11-7.1.i386.rpm

Once rpm is successfully installed, mount CD3 and install unixODBC* rpm

Mount CD3
#cd /media/E*/Server
#rpm -ivh unixODBC*

Update
=====

Frits Hoogland commented on the post and pointed me to Oracle yum (Yellowdog updater modified) for taking care of dependencies. I had heard of yum but I had never tried it earlier. But as I checked today, it is very easy to setup. Process is listed at http://public-yum.oracle.com/
I am documenting the steps for setting it up on OEL5

<span style="font-family: arial, helvetica, sans-serif;">#</span> cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-el5.repo

Edit the copied file based on your OEL5 release and set enabled=1. e.g

cat /etc/enterprise-release
Enterprise Linux Enterprise Linux Server release 5.3 (Carthage)

[el5_u3_base]
name=Enterprise Linux $releasever U3 - $basearch - base
baseurl=http://public-yum.oracle.com/repo/EnterpriseLinux/EL5/3/base/$basearch/
gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-el5
gpgcheck=1
enabled=1

To check

[rroot@db11g ~]# yum list ocfs2
Loaded plugins: security
Error: No matching Packages to list

ocfs2 packages are not available. Let’s install it now

[root@db11g ~]# yum install ocfs2

It’s cool..:)
There is one more method using which all the validated oracle packages can be installed during OEL5 installation.This also creates the oracle user/groups, sets up sysctl.conf, limits.conf, etc. Check out the article here
