LINUXRECIPE: 1. Oracle Database 11g GUI/Silent Installation

To install the Oracle Database 11g on a server follow the following steps:

1. Prepare a Centos/Oracle system and update it.
2. Remove open-java and install oracle-jdk.
3. Specify a fully qualified hostname and a static ip address.
4. Do the entry in /etc/hosts file of hostname and ip-address.
5. Disable selinux and iptables.
6. For Centos
# cd /etc/yum.repos.d
# wget https://public-yum.oracle.com/public-yum-ol6.repo
# wget https://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 -O /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
# yum install oracle-rdbms-server-11gR2-preinstall
It installs the required dependencies . We can install these dependencies one by one or manually using rpm command.

# /etc/security/limits.d/90-nproc.conf
* soft nofile 65536
* hard nofile 65536 // Now database user have permission to open this number of files.//

Check the following kernel parameters value. It should be equivalent to as described below or greater then. If a
kernel parameter value is greater then as described below then you do not need to specify it in kernel parameter file.

# /etc/sysctl.conf
kernel.shmall = 4294967296
kernel.shmax = 4294967295
kernel.shmmni = 4096
kernel.sem = 256 32000 100 142
kernel.msgmni = 2878
kernel.msgmax = 1892
kernel.msgmnb = 65535
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.wmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_max = 1048576
fs.aio-max-nr = 1048576

# sysctl -p


For Oracle Linux
# yum install oracle-rdbms-server-11gR2-preinstall

# /etc/sysctl.conf
net.core.rmem_default = 262144
net.core.wmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_max = 1048576
fs.aio-max-nr = 1048576

# sysctl -p

7. usermod -G oinstall oracle
passwd oracle
mkdir /u01
chmod -R 775 /u01
chown -R oracle:oinstall /u01

8. Now logout from system and login with oracle user
# unzip Oracle-Database-11.2.0.3.zip
# unzip p10404530_112030_Linux-x86-64_1of7.zip
# unzip p10404530_112030_Linux-x86-64_2of7.zip
# cd database
# ./runInstaller
