Create the directory for the software installation and assign ownership to oracle:oinstall
sudo mkdir /opt/oracle
sudo chown -R oracle:oinstall /opt/oracle
sudo chmod -R 775 /opt/oracle
In another console, login as oracle to make sure it works fine, then logout.
Append user oracle’s .bashrc with PATH and ORACLE:BASE,HOME and SID information
sudo vi /opt/oracle/.bashrc
export ORACLE_BASE=/opt/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10gR2
export ORACLE_SID=orcl
export PATH=$PATH:$ORACLE_HOME/bin
Make sure the correct kernel parmeters are appended to /etc/sysctl.conf
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.core.rmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_default = 262144
net.core.wmem_max = 262144
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
Set the kernel parameters or reboot
/sbin/sysctl -p
Set /etc/security/limits.conf
* soft nproc 2047
* hard nproc 16384
* soft nofile 1024
* hard nofile 65536
Create symbolic links and camoflage Kubuntu to look more like an enterprise rpm based distro because the oracle installer is expecting rhel, sles or asianux based distros.
sudo ln -s /usr/bin/awk /bin/awk
sudo ln -s /usr/bin/rpm /bin/rpm
sudo ln -s /lib/libgcc_s.so.1 /lib/libgcc_s.so
sudo ln -s /usr/bin/basename /bin/basename
Mount the Oracle10g CD and run the installer
/runInstaller -ignoreSysPrereqs
Installation will be uneventful provided above steps are followed
Enable the oracle user to dbshut, dbstart and lsnrctl start
