How to avoid kernel-uek is needed by oracle-rdbms-
server-12cR1-preinstall on CentOS while installing
Oracle Database 12c release 1
So as you should know Oracle Database Server 12c release 1 is finally out there
and this is my first post about it.
I've just finished to download some fundamental documents from Oracle website
such as "2 Day DBA", "New Features Guide", "Concepts Guide", "Upgrade Guide",
"Administrator's Guide" (1360 pages!!!), "Backup and Recovery User's Guide" (684
pages) and "Database Installation Guide for Linux".
I'm starting to read the "Database Installation Guide for Linux" guide, setting up a
running virtual CentOS machine and, of course, preparing to install the new Oracle
Database 12cR1:
I want to use the so useful rpm package provided by Oracle for automatically
complete default operating system configurations. There are many options
described on the documentation to configure your Oracle Linux distribution with
Oracle RDBMS pre-install rpm... but you can find some difficulties while using a
different release such as "RedHat like" distribution like that one I'm going to use: the
latest CentOS 6.4 distribution.
Do not use the following instruction on a production environment because they
won'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 from
Oracle public yum repository:

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 not
satisfied. I indeed installed the default minimal CentOS distribution.

8.el6.x86_64
15. sysstat is needed by oracle-rdbms-server-12cR1-preinstall-1.0-
8.el6.x86_64
Execute a yum install command with the previous missing packages and one of
them would not be available from the public CentOS repository. Just try to guess
which 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-install
package it discovers kernel-uek is still needed: UEK stands for Unbreakable
Enterprise Kernel.

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

3. error: Failed dependencies:
4. kernel-uek is needed by oracle-rdbms-server-12cR1-preinstall-1.0-
8.el6.x86_64
I don't want to use a different kernel just to install a configuration package in a testing
environment so why do not recompile that package instead and exclude that
dependency ?
I loved to recompile packages when I studied at the university: it was time of Red
Hat 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 to
compile its package. It was called "mockbuild". So simply create it using useradd
command 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 the
source information that you have to modify.
