Install Oracle 12C Release 1 (12.1) on Fedora 25

This article presents installation of Oracle database 12C(12.1) on Fedora 25. Read following article to install Fedora 25 Linux: Install Fedora 25(for comfort set 4G memory for your virtual machine). Software Software for 12CR1 is available on OTN or edelivery

Database software

If you are going to use version you can encounter bugs. Solutions for the bugs are described in the following post: Install Oracle 12C Release 1 (12.1) on Fedora 20.

OS configuration and preparation

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

su - root

It’s recommended to update your Fedora 25 kernel to latest version as root

dnf update

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.localdomain localhost

Add groups

#groups for database management
groupadd -g 54321 oinstall
groupadd -g 54322 dba
groupadd -g 54323 oper
groupadd -g 54324 backupdba
groupadd -g 54325 dgdba
groupadd -g 54326 kmdba
groupadd -g 54327 asmdba
groupadd -g 54328 asmoper
groupadd -g 54329 asmadmin

Add user Oracle for database software

useradd -u 54321 -g oinstall -G dba,oper,backupdba,dgdba,kmdba oracle

Change password for user Oracle

passwd oracle

OS configuration

Check which packages are installed and which are missing

rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE}(%{ARCH})\n' binutils \
compat-libcap1 \
compat-libstdc++-33 \
gcc \
gcc-c++ \
glibc \
glibc-devel \
ksh \
libaio \
libaio-devel \
libgcc \
libstdc++ \
libstdc++-devel \
libXi \
libXtst \
make \

Install missing packages (two options)

  • from dvd. It’s just example:
#directory with mounted Oracle Fedora 25 install disk 

cd /media/<Fedora 25>/Server/Packages 

#install missed packages (example for package ksh) 

rpm -Uvh ksh
  • or install via internet connection. It’s just example:
dnf install ksh

Add kernel parameters to “/etc/sysctl.conf”

fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 4398046511104
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500

Apply kernel parameters

/sbin/sysctl -p

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

oracle   soft   nofile   1024
oracle   hard   nofile   65536
oracle   soft   nproc    2047
oracle   hard   nproc    16384
oracle   soft   stack    10240
oracle   hard   stack    32768

Additional steps

Create .bash_profile for user oracle

# Oracle Settings
export TMP=/tmp

export ORACLE_BASE=/ora01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/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


Directory structure

Create directory structure ORACLE_BASE – /ora01/app/oracle ORACLE_HOME – /ora01/app/oracle/product/12.1.0/db_1

mkdir -p /ora01/app/oracle/product/12.1.0/db_1
chown oracle:oinstall -R /ora01

SSH server

I use it for later connection as user oracle in GNOME using command ssh oracle@fedora -X. Without it it won’t be possible to run X interfaces like Oracle Universal Installer.

Install ssh server. In workstation it should be already installed.

dnf install openssh-server

start ssh server

systemctl start sshd

verify it works

systemctl status sshd

Install database software

Let’s start with database software installation as oracle user. Usually I’m connected as my personal user tomasz in GNOME so you need to use ssh.

Connect as user Oracle

[tomasz@fedora ~]$ ssh -X

and start universal installer after unzipping binaries

--unizp software it will create directory database with binaries
--to install

--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
[oracle@fedora ~]$ envo
--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

  1. Followed exact same procedures, but net assistant but dbca failed.
    They worked in 12.2, though. May I should try net assistant separately.
