Install Oracle 11G Release 2 (11.2) on Fedora 20

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 or metalink In this installation I’m presenting installation for but for previous version 11.2.0.X it shouldn’t be different.

Oracle software which I verified


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. 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

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 !!!


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

--or unzip software
--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

--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

--run installation

1. Uncheck checkbox “I wish to receive security updates via My Oracle Support” and then click “Next” button.

2. Ignore following message and click “Yes” button.

3. Select “Skip software updates” and click “Next” button.

4. Select “Create and configure a database” then click “Next” button.

5. Select “Server Class” then click “Next” button.

9. Just click “Next” button.

10. Check checkbox “Ignore All” to ignore this error. Then click “Next” button.

11. Just click “Yes” button to continue with installation.

12. Summary screen just before installation. Click “Install” button.

13. Boring installation …

14. I received following error during linking binaries

To fix this error edit $ORACLE_HOME/sysman/lib/, search for the line


and replace the line with


then click “Retry” button

15. Database Configuration will start and create database for you.

16. You should see summary screen for your new database. Click “OK” button to continue with installation.

17. In the “middle” of installation you will be asked to run 2 scripts as user root. when scripts are executed just click “OK” button. Installation will proceed.

--execute scripts

18. Installation completed. Just click “Close” button.

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’.


Have a fun 🙂

  1. Excelente!!! Muchas gracias colega, siempre he tenido problemas cuando he tenido que instalar ORACLE 11g R2 sobre Fedora o RHE; mas aun tratandose de alguna version nueva de alguno de ellos… Eternamente agradecido 🙂

  2. Hi: In step 14. in my system the Retry button is unable when the installation hangs.
    Is there any way to get visible that button?

  3. This is the most perfect, step-by-step guide in installing Oracle Server on Linux. Thank you so much for this wonderful guide and screenshots that are absolutely spot on!

  4. When i execute the command “./runInstaller”, show a message =

    [oracle@localhost database]$ ./runInstaller

    Some requirement checks failed. You must fulfill these requirements before
    continuing with the installation,
    Continue? (y/n) [n]

    Could you help me?


    • Log into database as user sys without password. You must do it from UNIX oracle account

      as user root switch to oracle account
      unix user root> su – oracle

      as user oracle start sqlplus and log as sysdba
      unix user oracle> sqlplus / as sysdba

      change a user password in sqlplus
      sqlplus>alter user identified by ;


  5. Im using Oracle Linux 7.1. Install stuck/freezes just before summary screen (after warning 13016 before step 10 of 12). Inventory folder is created but empty, no log. In tmp lot of scripts is present.
    I have made couple installs without such problems. But this particulary system is build on quite new hardware, I suppose there is some problem in operating system itself exposed by launching java programs. Any sugesstions?

  6. Hello everyone,

    As guided above, I tried to install oracle 11gR2 accordingly but I got these errors related to (1.

    ### modify:
    ctxhx: $(CTXHXOBJ)
    -static $(LINK_CTXHX) $(CTXHXOBJ) $(INSO_LINK) /usr/lib64/stdc.a
    modify: /u01/app/oracle/product/11.2.0/dbhome_2/sysman/lib/
    Change to:
    $(MK_EMAGENT_NMECTL) -lnnz11

    ++ Retry didn’t work so tried again to run “. runInstaller”.
    but again getting same error, I came to know that my modified file no more after fresh installation in same directory since i opted ‘yes’ for directory. hence, it created altogether a new file.

    any idea???
