How to avoid kernel-uek is needed by oracle-rdbms-server-12cR1-preinstall on CentOS while installingOracle Database 12c release 1

So as you should know Oracle Database Server 12c release 1 is finally out thereand this is my first post about it.I've just finished to download some fundamental documents from Oracle websitesuch as "2 Day DBA", "New Features Guide", "Concepts Guide", "Upgrade Guide","Administrator's Guide" (1360 pages!!!), "Backup and Recovery User's Guide" (684pages) and "Database Installation Guide for Linux".

I'm starting to read the "Database Installation Guide for Linux" guide, setting up arunning virtual CentOS machine and, of course, preparing to install the new OracleDatabase 12cR1:I want to use the so useful rpm package provided by Oracle for automaticallycomplete default operating system configurations. There are many optionsdescribed on the documentation to configure your Oracle Linux distribution withOracle RDBMS pre-install rpm... but you can find some difficulties while using adifferent release such as "RedHat like" distribution like that one I'm going to use: thelatest CentOS 6.4 distribution.Do not use the following instruction on a production environment because theywon't be supported by Oracle guys: this post is only for testing purpose.

So open a terminal and use wget command to get the requested rpm package fromOracle public yum repository: view plainprint?

1. [root@localhost ~]$ wget http://public-yum.oracle.com/repo/OracleLinux/OL6/latest/x86_64/oracle-rdbms-server-12cR1-preinstall-1.0-8.el6.x86_64.rpm

2. --2013-07-04 10:15:03-- http://public-yum.oracle.com/repo/OracleLinux/OL6/latest/x86_64/oracle-rdbms-server-12cR1-preinstall-1.0-8.el6.x86_64.rpm

While installing the rpm package, it fails because some dependencies were notsatisfied. I indeed installed the default minimal CentOS distribution. view plainprint?

1. [root@localhost ~] rpm -Uvh oracle-rdbms-server-12cR1-preinstall-1.0-8.el6.x86_64.rpm

Execute a yum install command with the previous missing packages and one ofthem would not be available from the public CentOS repository. Just try to guesswhich one... view plainprint?

1. [root@localhost database]# yum -y install compat-libcap1 compat-libstdc++-33 gcc-c++ kernel-uek ksh libaio libaio-devel libstdc++-devel nfs-utils smartmontools sysstats smartmontools

Indeed when you issue again the command to install Oracle RDBMS pre-installpackage it discovers kernel-uek is still needed: UEK stands for UnbreakableEnterprise Kernel.

I don't want to use a different kernel just to install a configuration package in a testingenvironment so why do not recompile that package instead and exclude thatdependency ?I loved to recompile packages when I studied at the university: it was time of RedHat 4.0 and I should still have a CD-ROM to install it at home.So the first things you must have are the packages to rebuild a rpm package. view plainprint?

1. [root@localhost ~]# yum -y install rpm-build rpmdevtools

To avoid a rpmbuild error you have to create also the same user Oracle used tocompile its package. It was called "mockbuild". So simply create it using useraddcommand and then set a password for him. view plainprint?

1. [root@localhost ~]# useradd mockbuild -m -s /bin/bash 2. [root@localhost ~]# passwd mockbuild 3. Changing password for user mockbuild. 4. New password: 5. Retype new password: 6. passwd: all authentication tokens updated successfully.

Login with the new mockbuild user and download the rpm package containing all thesource information that you have to modify. view plainprint?
