Oracle Database 11g Release 2 (11.2) Installation On Fedora 12 (F12)
This article describes the installation of Oracle Database 11g Release 2 (11.2) 64-bit on Fedora 12 (F12) 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.
- Gnome Desktop Environment
- Graphical Internet
- Development Libraries
- Development Tools
- Server Configuration Tools
- Administration Tools
- Hardware Support
- Input Methods
- System Tools
- X Windows System
Variations on this installation may require additional steps for the Oracle installation to complete successfully.
- Download Software
- Unpack Files
- Hosts File
- Set Kernel Parameters
- Post Installation
Download the following software.
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.
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.
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.
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.
Alternatively, this alteration can be done using the GUI tool (Applications > System Settings > Security Level). Click on the SELinux tab and disable the feature. If SELinux is disabled after installation, the server will need a reboot for the change to take effect.
If you have installed the suggested package groups during the installation, the majority of the necessary packages will already be installed. Install the following packages.
yum install binutils yum install libaio libaio-devel yum install ksh yum install sysstat yum install unixODBC unixODBC-devel yum install compat-libstdc++-33
Notice we have not explicitly installed any 32-bit packages. The installer prerequisite checks will fail because of this, but they can be ignored and the installation will proceed normally.
Create the new groups and users.
groupadd oinstall groupadd dba groupadd oper groupadd asmadmin useradd -g oinstall -G dba,oper,asmadmin oracle passwd oracle
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.
Edit the "/etc/redhat-release" file replacing the current release information (Fedora release 12 (Constantine)) 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=$TMP; export TMPDIR ORACLE_HOSTNAME=f1264.localdomain; export ORACLE_HOSTNAME ORACLE_UNQNAME=DB11G; export ORACLE_UNQNAME ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE ORACLE_HOME=$ORACLE_BASE/product/11.2.0/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
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. You can see the installation I performed by clicking on the links below to see screen shots of each stage. Note. The prerequisites checks will show a number of packages missing, but these can be ignored.
