This article presents installation of Oracle database 12C(12.1) on Fedora 23. Read following article to install Fedora 23 Linux: Install Fedora 23(for comfort set 4G memory for your virtual machine). Software Software for 12CR1 is available on OTN or edelivery
- OTN: Oracle Database 12c Release 1 (12.1.0.2) Software (64-bit).
- edelivery: Oracle Database 12c Release 1 (12.1.0.2) Software (64-bit)

If you are going to use version 12.1.0.1 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 23 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.
127.0.0.1 fedora.dbaora.com 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-libstdc++-33 \ gcc \ gcc-c++ \ glibc \ glibc-common \ glibc-devel \ glibc-headers \ ksh \ libaio \ libaio-devel \ libgcc \ libstdc++ \ libstdc++-devel \ libXext \ libXtst \ libX11 \ libXau \ libXi \ make \ sysstat \ unixODBC \ unixODBC-devel \ zlib-devel
Install missing packages (two options)
- from dvd. It’s just example:
#directory with mounted Oracle Fedora 23 install disk cd /media/<Fedora 23>/Server/Packages #install missed packages (example for package unixODBC*) rpm -Uvh unixODBC*
- or install via internet connection. It’s just example:
dnf install unixODBC* zlib-devel
Add kernel parameters to /etc/sysctl.conf
--kernel parameters for 12gR1 installation 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
--shell limits for users oracle 12gR1 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft nproc 2047 oracle hard nproc 16384 oracle soft stack 10240 oracle hard stack 32768
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 !!!
SELINUX=permissive
Add the following line to the “/etc/pam.d/login” file, if it does not already exist.
session required pam_limits.so
Additional steps Create .bash_profile for user oracle
# Oracle Settings export TMP=/tmp export ORACLE_HOSTNAME=fedora.dbaora.com export ORACLE_UNQNAME=ORA12C export ORACLE_BASE=/ora01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1 export ORACLE_SID=ORA12C PATH=/usr/sbin:$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 envo
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
Install database software Let’s start with database software installation as oracle user.
