groupadd -g 54323 oper
groupadd -g 54329 asmadmin
Add user Oracle
--user id is the same as for 12c installations
useradd -u 54321 -g oinstall -G dba,oper,asmadmin oracle

Change password for user

passwd oracle
Add kernel parameters to /etc/sysctl.conf
kernel.shmmni = 4096 
kernel.shmmax = 4398046511104
kernel.shmall = 1073741824
kernel.sem = 250 32000 100 128

fs.aio-max-nr = 1048576
fs.file-max = 6815744
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586

Apply kernel parameters

/sbin/sysctl -p

Add following lines to set shell limits for user oracle in file /etc/security/limits.conf

oracle   soft   nproc    131072
oracle   hard   nproc    131072

The /etc/hosts file must contain a fully qualified name for the server.

<IP-address>  <fully-qualified-machine-name>  <machine-name>

For example. fedora localhost localhost.localdomain

Modify .bash_profile for user oracle in his home directory

# Oracle Settings
export TMP=/tmp

export ORACLE_BASE=/ora01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1


export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib;
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib;

alias cdob='cd $ORACLE_BASE'
alias cdoh='cd $ORACLE_HOME'
alias tns='cd $ORACLE_HOME/network/admin'
alias envo='env | grep ORACLE'

umask 022

Check which packages are installed and which are missing

rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE}(%{ARCH})\n' binutils \
compat-libstdc++-33 \
elfutils-libelf \
elfutils-libelf-devel \
gcc \
gcc-c++ \
glibc \
glibc-common \
glibc-devel \
glibc-headers \
ksh \
libaio \
libaio-devel \
libgcc \
libstdc++ \
libstdc++-devel \
make \
sysstat \
unixODBC \

Install missing packages. It’s just example (many in one step):

yum install unixODBC unixODBC-devel sysstat

Stop and disable firewall

systemctl stop firewalld
systemctl disable firewalld

Edit the “/etc/redhat-release” file replacing the current release information “Fedora release 21 (Twenty One)” with the following.

redhat release 6

Add the following line to the “/etc/pam.d/login” file, if it does not already exist.

session    required

Create directory structure

ORACLE_BASE – /ora01/app/oracle

ORACLE_HOME – /ora01/app/oracle/product/11.2.0/db_1

mkdir -p /ora01/app/oracle/product/11.2.0/db_1
chown oracle:oinstall -R /ora01

Secure Linux

Disable secure linux by editing the “/etc/selinux/config” file, making sure the SELINUX flag is set as follows. It requires REBOOT to be effective !!!


Install database software

Issue the following command to avoid problems with starting binary installation in graphical mode

xhost +<machine-name>

--in my case it's
xhost +fedora

Let’s start with database software installation as oracle user.

su - oracle

--or unzip software

--I defined 4 aliases in .bash_profile of user oracle to make 
--administration easier :)

[oracle@fedora ~]$ alias envo cdob cdoh tns
alias envo='env | grep ORACLE'
alias cdob='cd $ORACLE_BASE'
alias cdoh='cd $ORACLE_HOME'
alias tns='cd $ORACLE_HOME/network/admin'

--run alias command envo to display environment settings

--run alias command cdob and cdoh to check ORACLE_BASE, ORACLE_HOME 
[oracle@fedora ~]$ cdob
[oracle@fedora oracle]$ pwd

[oracle@fedora db_1]$ cdoh
[oracle@fedora db_1]$ pwd
