Installing Oracle Database 12c Release 1 on Fedora 25


This guide demonstrates the installation of Oracle Database 12c Release 1 (12.1) 64-bit on Fedora 25 64-bit. If you don't know how to install and prepare Fedora 25 for oracle database installation, please go through this step by step guide.







Prerequisites

You can download the Oracle software from OTN or MOS depending on your support status.

Unpack 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.

   

For example.

127.0.0.1       localhost.example.com localhost
192.168.56.141  fedora25.example.com  fedora25

Set Kernel Parameters

Create a file called "/etc/sysctl.d/98-oracle.conf" with the following contents.

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.

dnf groupinstall "MATE Desktop" -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-libstdc++-33 -y
dnf install compat-libstdc++-33.i686 -y
dnf install gcc -y
dnf install gcc-c++ -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 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 libaio -y
dnf install libaio.i686 -y
dnf install libaio-devel -y
dnf install libaio-devel.i686 -y
dnf install libXext -y
dnf install libXext.i686 -y
dnf install libXtst -y
dnf install libXtst.i686 -y
dnf install libX11 -y
dnf install libX11.i686 -y
dnf install libXau -y
dnf install libXau.i686 -y
dnf install libxcb -y
dnf install libxcb.i686 -y
dnf install libXi -y
dnf install libXi.i686 -y
dnf install make -y
dnf install sysstat -y
dnf install unixODBC -y
dnf install unixODBC-devel -y
dnf 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 is typically a bad idea. It's done here for simplicity, but for a real installation "/" should be reserved for the OS.

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

xhost +

Edit the "/etc/redhat-release" file replacing the current release information "Fedora release 25" with the following.

redhat release 7

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=fedora25.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=:0.0; export DISPLAY

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

./runInstaller

Proceed with the installation of your choice. Ignore any warnings about the system configuration.

You can see the following screenshots for reference and type of installation we performed.

Installation Problems

If you are doing this installation in a VM on a Mac/PC with a new-ish chipset, you may encounter some issues, especially around the Perl installation. If so, check out these notes.

During the linking phase, you may see the following error.

Error in invoking target 'irman ioracle' of makefile '/u01/app/oracle/product/12.1.0.2/db_1/rdbms/lib/ins_rdbms.mk'

To fix it, run the following command as the "oracle" user, then click the "Retry" button.

cp  $ORACLE_HOME/javavm/jdk/jdk6/lib/libjavavm12.a $ORACLE_HOME/lib/

During the database creation as part of the installation, or after when using the DBCA, you may get the following error.

Error while executing "/u01/app/oracle/product/12.1.0.2/db_1/rdbms/admin/dbmssml.sql". Refer to "/u01/app/oracle/cfgtoollogs/dbca/orcl/dbmssml0.log" for more details. Error in Process: /u01/app/oracle/product/12.1.0.2/db_1/perl/bin/perl

To fix it, follow the instructions to rebuild Perl as described towards the end of this post by Laurent Leturgez. You will have to redo the database creation.

Post Installation

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

Fedora release 25

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

Conclusion

This is for your information that oracle database is not supported and we do not recommend keeping oracle database on fedora Linux in production environment. However, consider using oracle Linux or red hat enterprise instead.
