Oracle Database 11g Release 1 (11.1) Installation On Fedora 11 (F11)

This article describes the installation of Oracle Database 11g Release 1 (11.1) on Fedora 11 (F11). 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_11gR1_database.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>

Set Kernel Parameters

Oracle recommend the following minimum parameter settings.

kernel.shmall = 2097152
kernel.shmmax = 2147483648 # Smallest of -> (Half the size of the physical memory) or (4GB - 1 byte)
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
fs.file-max = 65536 # 512 * PROCESSES
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default=4194304
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=262144

The current values can be tested using the following command.

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

For Fedora 11, the following lines should be appended to the "/etc/sysctl.conf" file. Some match default parameter values, but I've included them for clarity.

kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default=4194304
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=262144

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

Start the Firewall administration dialog (System > Administration > Firewall). Click the "Disable" button followed by the apply button on the toolbar, then close the dialog.

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

SELINUX=disabled

Alternatively, this alteration can be done using the GUI tool (System > Administration > SELinux Management). Set the "System Default Enforcing Mode" to "Disabled", agree to the confirmation dialog and reboot the system.

Setup

Install the following packages.

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

If you are performing the 64-bit installation, you will also need the following 32-bit packages.

The prerequisite check will still complain about missing packages, but ignore this. The installation will work fine.

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/11.1.0/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 11 (Leonidas)) 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=f1164.localdomain; export ORACLE_HOSTNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.1.0/db_1; export ORACLE_HOME
ORACLE_SID=DB11G; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:$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

During the installation enter the appropriate ORACLE_HOME and name then continue installation. Some of the prerequisite checks will not complete due to this not being a supported Linux distribution. Check each of these prerequisites to set them to "User Verified" then you can proceed.

Post Installation

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

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