This article presents how to install Oracle 11G on Fedora 20.

Read following article how to install Fedora 20 Linux: Install Fedora 20 (for comfort set 2G memory for your virtual machine before proceeding with Oracle software installation).

Installation software is available on OTN version 11.2.0.1 or metalink 11.2.0.4. In this installation I’m presenting installation for 11.2.0.4 but for previous version 11.2.0.X it shouldn’t be different.

Check article for new release Install Oracle 12C Release 1 (12.1) on Fedora 20

Oracle software which I verified

release 11.2.0.4

OS configuration and preparation

OS configuration is executed as root. To login as root just execute following command in terminal.

su - root

Add groups

--required groups
/usr/sbin/groupadd -g 501 oinstall
/usr/sbin/groupadd -g 502 dba
/usr/sbin/groupadd -g 503 oper

Add user Oracle

/usr/sbin/useradd -u 502 -g oinstall -G dba,oper 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
oracle   soft   nofile   131072
oracle   hard   nofile   131072
oracle   soft   core     unlimited
oracle   hard   core     unlimited
oracle   soft   memlock  50000000
oracle   hard   memlock  50000000

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

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

For example.

127.0.0.1 fedora fedora.dbaora.com localhost localhost.localdomain

Modify .bash_profile for user oracle in his home directory

# Oracle Settings
export TMP=/tmp

export ORACLE_HOSTNAME=fedora.dbaora.com
export ORACLE_UNQNAME=ORA11G
export ORACLE_BASE=/ora01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export ORACLE_SID=ORA11G

PATH=/usr/sbin:$PATH:$ORACLE_HOME/bin

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 \
unixODBC-devel

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

yum install unixODBC unixODBC-devel sysstat

Create directory structure

mkdir -p /ora01/app
chown oracle:oinstall /ora01/app
chmod 775 /ora01/app

create ORACLE_BASE directory for oracle

mkdir -p /ora01/app/oracle
chown oracle:oinstall /ora01/app/oracle
chmod 775 /ora01/app/oracle

Create ORACLE_HOME directory for oracle

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

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 !!!

SELINUX=disabled

Edit the “/etc/redhat-release” file replacing the current release information “Fedora release 20 (Heisenbug)” with the following.

redhat release 5

In Fedora 20 /tmp data is stored on tmpfs which consumes memory and is too small. To revert it back to storage just run following command and REBOOT machine to be effective.

systemctl mask tmp.mount

Install database software

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

su - oracle

--unizp software 11.2.0.3
unzip p10404530_112030_Linux-x86-64_1of7.zip
unzip p10404530_112030_Linux-x86-64_2of7.zip

--or unzip software 11.2.0.4
p13390677_112040_Linux-x86-64_1of7.zip
p13390677_112040_Linux-x86-64_2of7.zip
--I defined 4 aliases in .bash_profile of user oracle to make 
--administration heaven :)

[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
envo
ORACLE_UNQNAME=ORA11G
ORACLE_SID=ORA11G
ORACLE_BASE=/ora01/app/oracle
ORACLE_HOSTNAME=fedora.dbaora.com
ORACLE_HOME=/ora01/app/oracle/product/11.2.0/db_1

--run alias command cdob and cdoh to check ORACLE_BASE, ORACLE_HOME 
[oracle@fedora ~]$ cdob
[oracle@fedora oracle]$ pwd
/ora01/app/oracle

[oracle@fedora db_1]$ cdoh
[oracle@fedora db_1]$ pwd
/ora01/app/oracle/product/11.2.0/db_1

Post installation steps

Edit the “/etc/redhat-release” file to restore original release information.

Fedora release 20 (Heisenbug)

Edit the “/etc/oratab” file to set restart flag for ORA11G to ‘Y’.
