Oracle Database 18c Installation On Fedora 29 (F29)

Do not install Oracle on Fedora before reading this!

This article describes the installation of Oracle Database 18c 64-bit on Fedora 29 (F29) 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.

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
192.168.56.141  fedora29.localdomain  fedora29

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

fedora29.localdomain

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.

/sbin/sysctl -p

Add the following lines to a file called "/etc/security/limits.d/oracle-database-server-18c-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.

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.

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

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

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 -y bc    
dnf install -y binutils
# Next package will fail. Ignore it.
dnf install -y compat-libcap1
dnf install -y compat-libstdc++-33
dnf install -y compat-libstdc++-33.i686
dnf install -y elfutils-libelf.i686

# New for F29
dnf install -y libnsl2
dnf install -y libnsl2.i686

dnf install -y http://rpmfind.net/linux/fedora/linux/development/rawhide/Everything/x86_64/os/Packages/c/compat-libpthread-nonshared-2.28.9000-12.fc30.x86_64.rpm

#dnf update -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/18.0.0/dbhome_1
mkdir -p /u02/oradata
chown -R oracle:oinstall /u01 /u02
chmod -R 775 /u01 /u02

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 +<machine-name>

Edit the "/etc/redhat-release" file replacing the current release information "Fedora release 29 (Twenty Nine)" 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 F29.
rm -f /usr/lib64/libnsl.so.1
rm -f /usr/lib/libnsl.so.1
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

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

Perform a software-only installation either using interactive mode (GUI) or silent mode and run the root scripts when promted.

Run the root scripts when prompted.

As a root user, execute the following script(s):
        1. /u01/app/oraInvenotry/orainstRoot.sh
        2. /u01/app/oracle/product/18.0.0/dbhome_1/root.sh

You are now ready to create a database.

Database Creation

You create a database using the Database Configuration Assistant (DBCA). The interactive mode will display GUI screens to allow user input, while the silent mode will create the database without displaying any screens, as all required options are already specified on the command line.

# Start the listener.
lsnrctl start

# Interactive mode.
dbca

# Silent mode.
dbca -silent -createDatabase                                                   \
