Oracle Database 11g Release 2 (11.2) Installation On Fedora 20 (F20)

Do not install Oracle on Fedora before reading this!

This article describes the installation of Oracle Database 11g Release 2 (11.2) 64-bit on Fedora 20 (F20) 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 using one of the two link below. If you have access to My Oracle Support (MOS), then it is better to download the 11.2.0.4 version.

Unpack Files

Unzip the files.

unzip linux.x64_11gR2_database_1of2.zip
unzip linux.x64_11gR2_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
192.168.0.213   fedora20.localdomain  fedora20

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

fedora20.localdomain

Set Kernel Parameters

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

fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default=262144
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=1048586

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    nproc   2047
oracle              hard    nproc   16384
oracle              soft    nofile  4096
oracle              hard    nofile  65536
oracle              soft    stack   10240

Add the following line to the "/etc/pam.d/login" file, if it does not already exist.

session    required     pam_limits.so

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 elfutils-libelf -y
yum install elfutils-libelf-devel -y
yum install gcc -y
yum install gcc-c++ -y
yum install glibc -y
yum install glibc.i686 -y
yum install glibc-common -y
yum install glibc-devel -y
yum install glibc-headers -y
yum install glibc-devel.i686 -y
yum install ksh -y
yum install libaio -y
yum install libaio.i686 -y
yum install libaio-devel -y
yum install libaio-devel.i686 -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 make -y
yum install numactl -y
yum install numactl-devel -y
yum install sysstat -y
yum install unixODBC -y
yum install unixODBC.i686 -y
yum install unixODBC-devel -y
yum install unixODBC-devel.i686 -y

Create the new groups and users.

groupadd oinstall
groupadd dba
groupadd oper
groupadd asmadmin

useradd -g oinstall -G dba,oper,asmadmin oracle
passwd oracle

Note. We are not going to use the "asmadmin" group, since this installation will not use ASM.

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

mkdir -p /u01/app/oracle/product/11.2.0.4/db_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01

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 20 (Heisenbug)" 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
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR

ORACLE_HOSTNAME=fedora20.localdomain; export ORACLE_HOSTNAME
ORACLE_UNQNAME=DB11G; export ORACLE_UNQNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0.4/db_1; export ORACLE_HOME
ORACLE_SID=DB11G; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH

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

if [ $USER = "oracle" ]; then
  if [ $SHELL = "/bin/ksh" ]; then
    ulimit -p 16384
    ulimit -n 65536
  else
    ulimit -u 16384 -n 65536
  fi
fi

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 type of installation I performed by clicking on the links below to see screen shots of each stage. When installing 11.2.0.1, the prerequisites checks will list a number of packages as missing, but these can be ignored as we have installed newer versions. For 11.2.0.3 onward, only the "pdksh" package will be listed as missing, which can be ignored because we installed the "ksh" package instead.

  1. Configure Security Updates
  2. Select Install Option
  3. System Class
  4. Node Selection
  5. Select Install Type
  6. Typical Install Configuration
  7. Create Inventory
  8. Perform Prerequisite Checks
  9. Summary
  10. Install Product
  11. Database Configuration Assistant
  12. Database Configuration Assistant 2
  13. Execute Configuration Scripts
  14. Finish

During the link phase you will encounter an error invoking the "ins_emagent.mk" file. To fix this, edit the "$ORACLE_HOME/sysman/lib/ins_emagent.mk", doing a search and replace for the line shown below.

FROM:
$(MK_EMAGENT_NMECTL)
TO  :
$(MK_EMAGENT_NMECTL) -lnnz11

Click the "Retry" button.

Post Installation

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

Fedora release 20 (Heisenbug)

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

DB11G:/u01/app/oracle/product/11.2.0.4/db_1:Y
