Oracle 12.1.0.2 silent install and de-install

After Oracle Enterprise Linux setup we must set up some settings shown bellow:

Edit “/etc/hosts” file and add fully qualified name of your server.

[root@agcns Desktop]# vi /etc/hosts
127.0.0.1      localhost localhost.localdomain 
192.168.8.157  agcns agcns.localdomain

Then install oracle-rdbms-server-12cR1-preinstall package to perform all your prerequisite setup

[root@agcns Desktop]# yum install oracle-rdbms-server-12cR1-preinstall -y

Add lines bellow to the /etc/security/limits.conf  file.

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

Install  packages bellow if they are not already installed.

Set the password for the oracle user.

[root@agcns Desktop]# passwd oracle
Changing password for user oracle.
New password: 
Retype new password: 
passwd: all authentication tokens updated successfully.

change   /etc/security/limits.d/90-nproc.conf  like below.

*     -   nproc 16384
root soft nproc unlimited

Set  SELINUX to permissive, disable firewall and then reboot server:

[root@agcns]# vi /etc/selinux/config
SELINUX=permissive
[root@agcns]# service iptables stop
[root@agcns]# chkconfig iptables off
[root@agcns]# reboot

Create the ORACLE_HOME directory in which the Oracle software will be installed.

[root@agcns ~]# mkdir -p /u01/app/oracle/product/12.1.0.2/db_1
[root@agcns ~]# chown -R oracle:oinstall /u01
[root@agcns ~]# chmod -R 775 /u01

Switch to oracle account and unzip Oracle Installation zip files:

[oracle@agcns]$ unzip linuxamd64_12c_database_1of2.zip
[oracle@agcns]$ unzip linuxamd64_12c_database_2of2.zip

Edit bash_profile and add lines  bellow to this file:

[oracle@agcns]$ vi /home/oracle/.bash_profile

export PATH
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=agcns.localdomain
export ORACLE_UNQNAME=gcdb
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.1.0.2/db_1
export ORACLE_SID=gcdb
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

To perform silent installation  we must create and  use oraInst.loc and response file.

[root@agcns ~]# vi /etc/oraInst.loc
inventory_loc=/u01/app/oraInventory
inst_group=oinstall

[root@agcns ~]# chown oracle:oinstall /etc/oraInst.loc 
[root@agcns ~]# chmod 664 /etc/oraInst.loc
