Oracle Database 11g Release 2 (11.2) Installation On Fedora 15 (F15)

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 15 (F15) 64-bit. The article is based on a server installation with a minimum of 2G swap and secure Linux disabled. An example of this type of Linux installation can be seen here. The installation should also include the following package groups:

Variations on this installation may require additional steps for the Oracle installation to complete successfully.

Download Software

Download the following software:

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.localdomain  localhost
192.168.0.150   fedora15.localdomain  fedora15

Set Kernel Parameters

Oracle recommend the following minimum parameter settings.

fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
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

The current values can be tested using the following command.

/sbin/sysctl -a | grep <param-name>

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  1024
oracle              hard    nofile  65536

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

session    required     pam_limits.so

Disable secure linux by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.

SELINUX=disabled

If SELinux is disabled after installation, the server will need a reboot for the change to take effect.

Setup

If you have installed the suggested package groups during the installation, 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.

yum install binutils
yum install compat-libstdc++-33
yum install compat-libstdc++-33.i686
yum install elfutils-libelf
yum install elfutils-libelf-devel
yum install gcc
yum install gcc-c++
yum install glibc
yum install glibc.i686
yum install glibc-common
yum install glibc-devel
yum install glibc-headers
yum install glibc-devel.i686
yum install ksh
yum install libaio
yum install libaio.i686
yum install libaio-devel
yum install libaio-devel.i686
yum install libgcc
yum install libgcc.i686
yum install libstdc++
yum install libstdc++.i686
yum install libstdc++-devel
yum install make
yum install numactl
yum install numactl-devel
yum install sysstat
yum install unixODBC
yum install unixODBC.i686
yum install unixODBC-devel
yum install unixODBC-devel.i686

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/db_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01

Login as root and issue the following command.

xhost +<machine-name>

Edit the "/etc/redhat-release" file replacing the current release information "Fedora release 15 (Lovelock)" with the following.

redhat release 5

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

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

ORACLE_HOSTNAME=fedora15.localdomain; export ORACLE_HOSTNAME
ORACLE_UNQNAME=DB11G; export ORACLE_UNQNAME

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. Note. The prerequisites checks will show the "pdksh" package as missing, but this can be ignored. The emagent will fail to link and produce an error message. When this happens, click the "Continue" button and the installation will complete.
