Oracle Database 12c Release 1 (12.1) Installation On Fedora 25 (F25)
This article describes the installation of Oracle Database 12c Release 1 (12.1) 64-bit on Fedora 25 (F25) 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.

- Post Installation
Download the Oracle software from OTN or MOS depending on your support status.
- OTN: Oracle Database 12c Release 1 (18.104.22.168) Software (64-bit).
- edelivery: Oracle Database 12c Release 1 (22.214.171.124) Software (64-bit)
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.
The "/etc/hosts" file must contain a fully qualified name for the server.
<IP-address> <fully-qualified-machine-name> <machine-name>
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 192.168.56.141 fedora25.localdomain fedora25
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 the following command to change the current kernel parameters.
Add the following lines to a file called "/etc/security/limits.d/oracle-rdbms-server-12cR1-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 32768 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.
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/126.96.36.199/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.
Edit the "/etc/redhat-release" file replacing the current release information "Fedora release 25 (Twenty Five)" 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/188.8.131.52/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
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.
Proceed with the installation of your choice. Ignore any warnings about the system configuration.
You can see the type of installation I performed by clicking on the links below to see screen shots of each stage.
- Configure Security Updates
- My Oracle Support Credentials
- Select Installation Type
- System Class
- Grid Installation Options
- Select Install Type
- Typical Install Configuration
- Create Inventory
- Perform Prerequisite Checks
- Install Product
- Execute Configuration Scripts
- Oracle Database Configuration
- Database Configuration Assistant
- Database Configuration Assistant Complete
- Database Express 12c Login
- Database Express 12c Dashboard
The "Database Configuration Assistant Complete" screen displays the Database Express 12c URL, which will be something like "https://fedora25.localdomain:5500/em".
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/184.108.40.206/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/220.127.116.11/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/18.104.22.168/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.
Edit the "/etc/redhat-release" file restoring the original release information.
Fedora release 25 (Twenty Five)
Edit the "/etc/oratab" file setting the restart flag for each instance to 'Y'.

Hope this helps. Regards Tim...
