Oracle Database 12c Release 1 (12.1) Installation On Fedora 19 (F19)

Do not install Oracle on Fedora before reading this!

This article describes the installation of Oracle Database 12c Release 1 (12.1) 64-bit on Fedora 19 (F19) 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 files.

unzip linuxamd64_12102_database_1of2.zip
unzip linuxamd64_12102_database_2of2.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.

127.0.0.1       localhost localhost.localdomain localhost4 localhost4.localdomain4
192.168.0.212   fedora19.localdomain  fedora19

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

fedora19.localdomain

Set Kernel Parameters

Add or amend the following lines in the "/etc/sysctl.conf" file.

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

Run the following command to change the current kernel parameters.

/sbin/sysctl -p

Add the following lines to the "/etc/security/limits.conf" file.

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

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.

SELINUX=permissive

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

Setup

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

yum groupinstall "GNOME Desktop" -y
yum groupinstall "Development Tools" -y
yum groupinstall "Administration Tools" -y
yum groupinstall "System Tools" -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.

yum install binutils -y
yum install compat-libstdc++-33 -y
yum install compat-libstdc++-33.i686 -y
yum install gcc -y
yum install gcc-c++ -y
yum install glibc -y
yum install glibc.i686 -y
yum install glibc-devel -y
yum install glibc-devel.i686 -y
yum install ksh -y
yum install libgcc -y
yum install libgcc.i686 -y
yum install libstdc++ -y
yum install libstdc++.i686 -y
yum install libstdc++-devel -y
yum install libstdc++-devel.i686 -y
yum install libaio -y
yum install libaio.i686 -y
yum install libaio-devel -y
yum install libaio-devel.i686 -y
yum install libXext -y
yum install libXext.i686 -y
yum install libXtst -y
yum install libXtst.i686 -y
yum install libX11 -y
yum install libX11.i686 -y
yum install libXau -y
yum install libXau.i686 -y
yum install libxcb -y
yum install libxcb.i686 -y
yum install libXi -y
yum install libXi.i686 -y
yum install make -y
yum install sysstat -y
yum install unixODBC -y
yum install unixODBC-devel -y
yum install zlib-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 54327 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/12.1.0.2/db_1
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 19 (Schrödinger’s Cat)" with the following.

redhat release 6

Login as the oracle user and add the following lines at the end of the "/home/oracle/.bash_profile" file.

# Oracle Settings
export TMP=/tmp
export TMPDIR=$TMP

export ORACLE_HOSTNAME=fedora19.localdomain
export ORACLE_UNQNAME=cdb1
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.1.0.2/db_1
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

Installation

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

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

Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory.

./runInstaller

Proceed with the installation of your choice.

You can see the type of installation I performed by clicking on the links below to see screen shots of each stage.

The "Database Configuration Assistant Complete" screen displays the Database Express 12c URL, which will be something like "https://fedora20.localdomain:5500/em".

Post Installation

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

Fedora release 19 (Schrödinger’s Cat)

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

cdb1:/u01/app/oracle/product/12.1.0.2/db_1:Y

12.1.0.1 Notes

Oracle 12c (12.1.0.2) installs cleanly. If you attempt the installation using 12.1.0.1 there will be some problems. The notes here explain how to complete a 12.1.0.1 installation.

Due to the issues during the linking phase, it probably makes sense to do a relink, just to make sure.

dbshut $ORACLE_HOME
cd $ORACLE_HOME/bin
./relink all
# Following line should return no errors.
grep -i err $ORACLE_HOME/install/relink.log
dbstart $ORACLE_HOME
