Oracle Database 12c Release 2 (12.2) Installation On Fedora 28 (F28)

Do not install Oracle on Fedora before reading this!

This article describes the installation of Oracle Database 12c Release 2 (12.2) 64-bit on Fedora 28 (F28) 64-bit. The article is based on a server installation with a minimum of 2G swap and secure Linux set to permissive. An example of this type of Linux installation can be seen here.

Download Software

Download the Oracle software from OTN or MOS depending on your support status.

Unpack Files

Unzip the file.

unzip linuxx64_12201_database.zip

You should now have a single directory called "database" containing installation files.

Hosts File

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

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

For example.       localhost localhost.localdomain localhost4 localhost4.localdomain4  fedora28.localdomain  fedora28

Set the correct hostname in the "/etc/hostname" file.


Set Kernel Parameters

Add the following lines to the "/etc/sysctl.conf" file, or in a file called "/etc/sysctl.d/98-oracle.conf".

fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 4398046511104
kernel.panic_on_oops = 1
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.conf.all.rp_filter = 2
net.ipv4.conf.default.rp_filter = 2
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500

Run one of the following commands to change the current kernel parameters, depending on which file you edited.

/sbin/sysctl -p
# Or
/sbin/sysctl -p /etc/sysctl.d/98-oracle.conf

Add the following lines to a file called "/etc/security/limits.d/oracle-database-server-12cR2-preinstall.conf" file.

oracle   soft   nofile    1024
oracle   hard   nofile    65536
oracle   soft   nproc    16384
oracle   hard   nproc    16384
oracle   soft   stack    10240
oracle   hard   stack    32868
oracle   hard   memlock    134217728
oracle   soft   memlock    134217728

Stop and disable the firewall. You can configure it later if you wish.

# systemctl stop firewalld
# systemctl disable firewalld

Set SELinux to permissive by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.


The server will need a reboot for the change to take effect.


Before we consider the packages required by the Oracle installation, it's probably worth making sure some basic package groups are installed.

# Use desktop of your choice.
dnf groupinstall GNOME -y

dnf groupinstall "Development Tools" -y
dnf groupinstall "Administration Tools" -y
dnf groupinstall "System Tools" -y
dnf install firefox -y

If you have installed the suggested package groups, the majority of the necessary packages will already be installed. The following packages are listed as required, including the 32-bit version of some of the packages. Many of the packages should be installed already.

dnf install binutils -y
dnf install compat-libcap1 -y
dnf install compat-libstdc++-33 -y
dnf install compat-libstdc++-33.i686 -y
dnf install glibc -y
dnf install glibc.i686 -y
dnf install glibc-devel -y
dnf install glibc-devel.i686 -y
dnf install ksh -y
dnf install libaio -y
dnf install libaio.i686 -y
dnf install libaio-devel -y
dnf install libaio-devel.i686 -y
dnf install libX11 -y
dnf install libX11.i686 -y
dnf install libXau -y
dnf install libXau.i686 -y
dnf install libXi -y
dnf install libXi.i686 -y
dnf install libXtst -y
dnf install libXtst.i686 -y
dnf install libgcc -y
dnf install libgcc.i686 -y
dnf install libstdc++ -y
dnf install libstdc++.i686 -y
dnf install libstdc++-devel -y
dnf install libstdc++-devel.i686 -y
dnf install libxcb -y
dnf install libxcb.i686 -y
dnf install make -y
dnf install nfs-utils -y
dnf install net-tools -y
dnf install smartmontools -y
dnf install sysstat -y
dnf install unixODBC -y
dnf install unixODBC-devel -y
dnf install elfutils-libelf-devel -y

Create the new groups and users.

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 54328 asmdba
#groupadd -g 54328 asmoper
#groupadd -g 54329 asmadmin

useradd -u 54321 -g oinstall -G dba,oper oracle
passwd oracle

We are not going to use the extra groups, but include them if you do plan on using them.

Create the directories in which the Oracle software will be installed.

mkdir -p /u01/app/oracle/product/
chown -R oracle:oinstall /u01
chmod -R 775 /u01

Putting mount points directly under root without mounting separate disks to them is typically a bad idea. It's done here for simplicity, but for a real installation "/" storage should be reserved for the OS.

If you are using X Emulation, login as root and issue the following command.

xhost +<machine-name>

Edit the "/etc/redhat-release" file replacing the current release information "Fedora release 28 (Twenty Eight)" with the following.

redhat release 7

You will need to add the following symbolic links or the Oracle Universal Installer (OUI) will not start.

# Fix for Oracle on F28.
ln -s /usr/lib64/libnsl.so.2.0.0 /usr/lib64/libnsl.so.1
ln -s /usr/lib/libnsl.so.2.0.0 /usr/lib/libnsl.so.1

Set up the environment for the "oracle" user.

mkdir -p /home/oracle/scripts

cat > /home/oracle/scripts/setEnv.sh <<EOF
# Oracle Settings
export TMP=/tmp
export TMPDIR=\$TMP

export ORACLE_HOSTNAME=fedora28.localdomain
export ORACLE_UNQNAME=cdb1
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=\$ORACLE_BASE/product/
export ORACLE_SID=cdb1

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

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

echo ". /home/oracle/scripts/setEnv.sh" >> /home/oracle/.bash_profile

chown -R oracle.oinstall /home/oracle/scripts


Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.

DISPLAY=<machine-name>:0.0; export DISPLAY

Perform a software-only installation either using interactive mode (GUI) or silent mode.

# Interactive mode (GUI).
cd /u01/software/database

# Silent mode (software unzipped below "/u01/software")
cd /u01/software/database
./runInstaller -ignoreSysPrereqs -ignorePrereq -waitforcompletion -showProgress -silent \
    -responseFile /u01/software/database/response/db_install.rsp \
    oracle.install.option=INSTALL_DB_SWONLY \
    ORACLE_HOSTNAME=fedora28.localdomain \
    UNIX_GROUP_NAME=oinstall \
    INVENTORY_LOCATION=/u01/app/oraInventory \
    ORACLE_HOME=/u01/app/oracle/product/ \
    ORACLE_BASE=/u01/app/oracle \
    oracle.install.db.InstallEdition=EE \
    oracle.install.db.OSDBA_GROUP=dba \
    oracle.install.db.OSBACKUPDBA_GROUP=dba \
    oracle.install.db.OSDGDBA_GROUP=dba \
    oracle.install.db.OSKMDBA_GROUP=dba \
    oracle.install.db.OSRACDBA_GROUP=dba \

Run the root scripts when prompted.

As a root user, execute the following script(s):
        1. /u01/app/oraInventory/orainstRoot.sh
        2. /u01/app/oracle/product/

You can read more about silent installations here.

Clean up some library stubs and relink the software. Thanks to Andy Campbell for telling me about this solution.

cd $ORACLE_HOME/lib/stubs
mkdir BAK
mv libc* BAK/
$ORACLE_HOME/bin/relink all

You are now ready to create a database.

Database Creation

You should now be able to create a database in the normal way using the DBCA in interactive (GUI) or silent mode. Here is the silent mode database creation I used.

# Interactive mode (GUI).

# Silent mode.
dbca -silent -createDatabase \
     -templateName General_Purpose.dbc \
     -gdbname cdb1 -sid cdb1 -responseFile NO_VALUE \
     -characterSet AL32UTF8 \
     -sysPassword OraPasswd1 \
     -systemPassword OraPasswd1 \
     -createAsContainerDatabase true \
     -numberOfPDBs 1 \
     -pdbName pdb1 \
     -pdbAdminPassword OraPasswd1 \
     -databaseType MULTIPURPOSE \
     -memoryMgmtType auto_sga \
     -totalMemory 1536 \
     -storageType FS \
     -datafileDestination "/u01/app/oracle/oradata/" \
     -redoLogFileSize 50 \
     -emConfiguration NONE \

You can read more about silent database creation here.

Post Installation

Edit the "/etc/redhat-release" file restoring the original release information.

Fedora release 28 (Twenty Eight)

Edit the "/etc/oratab" file setting the restart flag for each instance to 'Y'.
