This article will show how to install Oracle 11gR2 RDBMS software in silent mode ( Command line only, no GUI).

It is usual that you have an shell terminal access to a server without graphical X display.
In that case, it may be usefull to install Oracle in silent mode.

Before starting, you will need :
- Oracle Linux 7 installed (see oel7 installation here)
- Oracle Grid Infrastructure installed (optional but recommanded, see install here)
- Oracle 11g installation files downloaded
   * 11.2.0.4 is available on MOS (recommanded)
   * 11.2.0.1 is available on OTN
- at least 5GB free disk space

Be aware ...
Starting with Oracle Database 11g Release 2 (11.2.0.4), Oracle Linux 7 and Red Hat Enterprise Linux 7 are supported on Linux x86-64 systems. (see certification information here)

Install Prerequisites

Automatic preinstall setup

The easiest way is to use an oracle package call "oracle-rdbms-server-11gR2-preinstall"

Overview

This special package will install required packages needed for Oracle 11g and also add/change some system parameters by modifying the following system files : /etc/sysctl.conf /etc/passwd /etc/group /etc/security/limits.conf

Here is its packages dependencies below.

oracle-rdbms-server-11gR2-preinstall.x86_64
    |- compat-libcap1
    |- compat-libstdc++-33
    |- gcc-c++
    |    |- gcc
    |    |    |- libgomp
    |    |    |- cpp
    |    |    `- libgcc
    |    `- libstdc++
    |- ksh
    |- libaio-devel
    `- libstdc++-devel

Deployment

Install required packages with these two following commands as root:

$ yum -y --enablerepo=ol7_addons install oracle-rdbms-server-11gR2-preinstall.x86_64

$ yum -y install glibc

Check commands output below

# Install all required package with oracle-rdbms-server-11gR2-preinstall
[root]$ yum -y --enablerepo=ol7_addons install oracle-rdbms-server-11gR2-preinstall.x86_64

Manual preinstall setup

Packages

Install required packages with the following command

[root]$ yum -y install compat-libcap1 compat-libstdc++-33 gcc-c++ ksh libaio-devel libstdc++-devel glibc

Users and groups

Create minimal required groups and users with the following commands:

[root]$ /usr/sbin/groupadd -g 54321 oinstall
[root]$ /usr/sbin/groupadd -g 54322 dba
[root]$ /usr/sbin/useradd -u 54321 oracle
[root]$ /usr/sbin/usermod -g oinstall -G dba oracle
[root]$ passwd oracle

Kernel parameters

In order to satisfy the Oracle installer's requirements, modify the /etc/sysctl.conf file by adding or amending the following lines:

fs.file-max = 6815744
fs.aio-max-nr = 1048576
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 4398046511104
kernel.panic_on_oops = 1
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.ip_local_port_range = 9000 65500

Make these changes effective immediately with the following command

[root]$ /sbin/sysctl -p

Shell Limits

To improve the performance, you can increase the shell limits for the oracle user by adding the following lines to /etc/security/limits.conf:

oracle   soft   nofile   1024
oracle   hard   nofile   65536
oracle   soft   nproc    16384
oracle   hard   nproc    16384
oracle   soft   stack    10240
oracle   hard   stack    32768

Make sure, the following lines is in /etc/pam.d/login file:

session required pam_limits.so

Additional setup

Additionnal packages

[root]$ yum -y install unixODBC elfutils-libelf-devel xorg-x11-xinit sysstat rsync

Hosts files

In order to connect to oracle from another machine, Oracle need a fully qualified name for the server otherwise loopback connecton will be used.
You will need to add a new line in /etc/hosts structured as follow

<IP-address>  <fully-qualified-machine-name>  <machine-name>

For example, a server named oel7db in localdomain with 192.168.0.34 ip address

# Add the new host line
[root]$ printf "\n192.168.0.34\toel7db.localdomain oel7db" >> /etc/hosts

# /etc/hosts should contain at least these two lines
[root]$ cat /etc/hosts
    127.0.0.1       localhost localhost.localdomain
    192.168.0.34    oel7db.localdomain  oel7db

# Set the hostname
[root]$ echo "oel7db.localdomain" > /etc/hostname
[root]$ hostname "oel7db.localdomain"

Oracle user limits

Make sure oracle user's default shell is Bourne, Bash, or Korn shell.
Then add the following lines to the end of /etc/profile file:

if [ $USER = "oracle" ]; then
    if [ $SHELL = "/bin/ksh" ]; then
        ulimit -p 16384
        ulimit -n 65536
    else
        ulimit -u 16384 -n 65536
    fi
fi

Mountpoint with dedicated filesystem

It is advised to create a mountpoint with a dedicated filesystem which will store oracle binaries for several reasons:

  • to not to fill up root filesystem
  • to increase this specific filesystem only if needed
  • to be able to move disk and filesystems to an other server

Execute theses commands as root for a new sdb disk:

# Create filesystem
$ fdisk /dev/sdb
    # then press p <enter> <enter> w

$ mkfs -t xfs /dev/sdb1

# Create mountpoint directory
$ mkdir /u01
$ chown oracle.oinstall /u01
$ chmod 775 /u01

# Mount mountpoint
$ printf "\n/dev/sdb1 \t/u01\txfs \tdefaults \t1 2\n" >> /etc/fstab
$ mount /u01

Check output below

# If sdb is the new added disk
# Create partition on the new disk
[root]$ fdisk /dev/sdb
    Welcome to fdisk (util-linux 2.23.2).

    Changes will remain in memory only, until you decide to write them.
    Be careful before using the write command.
