Oracle 19c Silent Installation

Oracle 19c Silent Installation : In this article we will discuss about Oracle 19c Silent Installation. Here we will do this installation in Oracle 19c Database (19.3.0.0).

Overview :

• Usually to install 19.3.0.0 database software we will use ./runInstaller graphical user interface.
• Some times may not have access to a graphical user interface.
• Silent mode installation allows to configure necessary Oracle components without using graphical interface
• In this response file can be used to provide all the required information for the installation, so no additional user input is required.

Steps:

• Download Software
• Hosts File
• Oracle Installation Prerequisites
  • Automatic Setup
  • Manual Setup
  • Additional Setup
• Installation
• Unzip software
• Install Database Software
• Configure listener
• Run dbca to create a database
• Post Installation

Download Software :

Download the Oracle software from OTN or MOS depending on your support status.

https://www.oracle.com/in/database/technologies/oracle-database-software-downloads.html

Hosts File :

The “/etc/hosts” file must contain a fully qualified name for the server.

[root@orakldba ~]# hostname
orakldba.localdomain
[root@orakldba ~]#
[root@orakldba ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.159.0.112 orakldba.localdomain orakldba

Oracle Installation Prerequisites :

Perform either the Automatic Setup or the Manual Setup to complete the basic prerequisites. The Additional Setup is required for all installations.

Automatic Setup:

commands must run on root user.

# yum search preinstall

# yum install oracle-database-preinstall-19c.x86_64 -y

It is probably worth doing a full update as well, but this is not strictly speaking necessary.

# yum update -y

If you are using RHEL7 or CentOS7, you can pick up the PRM from the OL7 repository and install it. It will pull the dependencies from your normal repositories.

# yum install -y https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

Manual Setup:

If you have not used the “oracle-database-preinstall-19c” package to perform all prerequisites, you will need to manually perform the following setup tasks.

Add the following lines to the “/etc/sysctl.conf“ file, or in a file called “/etc/sysctl.d/98-oracle.conf”.

fs.file-max = 6815744
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.conf.all.rp_filter = 2
net.ipv4.conf.default.rp_filter = 2
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500

Then run this following commands as root user :

# /sbin/sysctl -p

Or

# /sbin/sysctl -p /etc/sysctl.d/98-oracle.conf

Add the following lines to this file “/etc/security/limits.d/oracle-database-preinstall-19c.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
oracle hard memlock 134217728
oracle soft memlock 134217728

The following packages are listed as required. Many of the packages should be installed already.

yum install -y bc
yum install -y binutils
yum install -y compat-libcap1
yum install -y compat-libstdc++-33
yum install -y dtrace-modules
yum install -y dtrace-modules-headers
yum install -y dtrace-modules-provider-headers
yum install -y dtrace-utils
yum install -y elfutils-libelf
yum install -y elfutils-libelf-devel
yum install -y fontconfig-devel
yum install -y glibc
yum install -y glibc-devel
yum install -y ksh
yum install -y libaio
yum install -y libaio-devel
yum install -y libdtrace-ctf-devel
yum install -y libXrender
yum install -y libXrender-devel
yum install -y libX11
yum install -y libXau
yum install -y libXi
yum install -y libXtst
yum install -y libgcc
yum install -y librdmacm-devel
yum install -y libstdc++
yum install -y libstdc++-devel
yum install -y libxcb
yum install -y make
yum install -y net-tools # Clusterware
yum install -y nfs-utils # ACFS
yum install -y python # ACFS
yum install -y python-configshell # ACFS
yum install -y python-rtslib # ACFS
yum install -y python-six # ACFS
yum install -y targetcli # ACFS
yum install -y smartmontools
yum install -y sysstat
yum install -y unixODBC

Create the new groups and users.

groupadd -g 54321 oinstall
groupadd -g 54322 dba
groupadd -g 54323 oper

useradd -u 54321 -g oinstall -G dba,oper oracle

Set the password for the “oracle” user.

[root@vm-1 ~]#
[root@vm-1 ~]# passwd oracle
Changing password for user oracle.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.
[root@vm-1 ~]#

Additional Setup:

The following steps must be performed, whether you did the manual or automatic setup.
Set secure Linux to disabled by editing the “/etc/selinux/config” file.

SELINUX=permissive

Once the change is complete, restart the server or run the following command as ‘root’ user.

setenforce Permissive

If you have the Linux firewall enabled, you will need to stop and disable it.

run this following commands as root user :

# systemctl stop firewalld

# systemctl disable firewalld

Create the directories in which the Oracle software will be installed.

mkdir -p /u01/app/oracle/product/19.0.0/dbhome_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01

Unless you are working from the console, or using SSH tunnelling, login as root and issue the following command.

xhost + <machine-name>

Add the following lines at the end of the “/home/oracle/.bash_profile” file.

# Oracle Settings
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=orakldba.localdomain
export ORACLE_UNQNAME=prod.localdomain
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/19.0.0/dbhome_1
export ORA_INVENTORY=/u01/app/oraInventory
export ORACLE_SID=prod
export PATH=/usr/sbin:/usr/local/bin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

After settings done on .bash_profile run :

[oracle@orakldba ~]$
[oracle@orakldba ~]$ . ./.bash_profile
[oracle@orakldba ~]$

Installation:

Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.

DISPLAY=:0.0; export DISPLAY

1. Unzip software :

unzip -o /u01/LINUX.X64_193000_db_home.zip -d /u01/app/oracle/product/19.0.0/dbhome_1/

2. At first you need to take Backup response file :

Response files:

Once Oracle 19C binaries are unzipped. In following directories you can find response files that stores parameters necessary to install Oracle components:

• db_install.rsp – used to install oracle binaries, install/upgrade a database in silent mode
• dbca.rsp – used to install/configure/delete a database in silent mode
• netca.rsp – used to configure simple network for oracle database in silent mode

[oracle@orakldba ~]$
[oracle@orakldba ~]$ cd /u01/app/oracle/product/19.0.0/dbhome_1/install/response
[oracle@orakldba response]$ ls -ltr
total 20
-rw-r--r-- 1 oracle oinstall 19932 Feb  6  2019 db_install.rsp

[oracle@orakldba response]$
[oracle@orakldba response]$ cp db_install.rsp db_install.rsp_bkp
[oracle@orakldba response]$
[oracle@orakldba response]$ ls -ltr
total 60
-rw-rw-r-- 1 oracle oinstall 22924 Jan 26  2017 db_install.rsp
-rw-rw-r-- 1 oracle oinstall 22924 Jan 26  2017 db_install.rsp_bkp
[oracle@orakldba response]$
[oracle@orakldba response]$ cd $ORACLE_HOME/assistants/dbca
[oracle@orakldba dbca]$
[oracle@orakldba dbca]$ cp dbca.rsp dbca.rsp_bkp
[oracle@orakldba dbca]$
[oracle@orakldba dbca]$ ls -ltr
-rw-rw-r-- 1 oracle oinstall 22924 Jan 26  2017 dbca.rsp

-rwxrwxr-x 1 oracle oinstall 25502 Jan  5  2017 netca.rsp_bkp
[oracle@orakldba netca]$

3. Then Modify the response file :

[oracle@orakldba response]$
[oracle@orakldba response]$ cat db_install.rsp
