In this article will perform step by step installation of Oracle 19c single instance database on Oracle Linux 7 operating system hosted on virtual box.
Prior to proceeding with the steps , do refer following link to setup a LAB environment which includes Installation of Oracle Virtual Box on windows and operating system Oracle Linux 7 setup.
Oracle Linux Installation on Virtual Box
Oracle 19c installation steps will include ..
1. Setting up internet network connection from virtual machine
2. Installation of prerequisite oracle 19c
3. Configuring & downloading Oracle 19c home setup
4. Performing oracle 19c installation
5. De-installation / Setup Cleanup
Lets begin ..
1. Setting up internet network connection from virtual machine
Internet connectivity within virtual host is must to install pre-requisite rpm for oracle 19c database installation as well few ad-hoc dependent rpm's using yum
Verify if NAT is selected for Adpater 1..
Add port forwarding for connecting the virtual machine from outside terminal ..
In windows host make sure wireless network ethernet adapter internet sharing is enabled from below path
Control Panel\Network and Internet\Network Connections
Make sure ONBOOT=yes in /etc/sysconfig/network-scripts
Either reboot the virtual machine or use ifdown & ifup to reflect appropriate nameserver entry in resolv.conf post host entry addition
ifconfig -a output should look like below ..
2. Installation of prerequisite oracle 19c
Downlod & install the oracle 19c database preinstall rpm which will create the user, groups and install necessary kernal packages/rpm's required as a prerequisites ..
[root@oraclesrv ~]# yum -y install
oracle-database-preinstall-19c

--> Running transaction check
---> Package oracle-database-preinstall-19c.
3. Configuring & downloading Oracle 19c home setup
Create installation directory for oracle home ..
[root@oraclesrv ~]# id oracle

4. Performing oracle 19c installation
Create separate disks as /u01 & /data . also add swap space as their should not be any exception to be ignored using this link
[oracle@oraclesrv /]$ cd /u01/app/oracle/db1
[oracle@oraclesrv db1]$ ./runInstaller
As a new feature in oracle 19c root password to be supplied to avoid manual execution of post installation scripts
fix this swap issue following these steps
Setup up bash profile for environment variables ..
[oracle@oraclesrv ~]$ cat .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
ORACLE_HOME=/u01/app/oracle/db1
export ORACLE_HOME
ORACLE_SID=LEARN
export ORACLE_SID
PATH=$PATH:$HOME/.local/bin:$HOME/bin:$ORACLE_HOME/bin
export PATH
[oracle@oraclesrv ~]$
[oracle@oraclesrv ~]$ . ./.bash_profile
Try accessing EM express https://<servername>:5500/em
few commands on pdb to play ..
