Oracle 19c Installation on Linux

Oracle 19c adds more features to Oracle database and this article demonstrates Oracle 19c installation on Linux 7. We will be using Oracle Linux 7 and Oracle Database 19.3 softwares for this activity. We will also be looking at database creation via DBCA.

Oracle 19c Pre-requisites

Use the YUM repository to perform all the pre-install steps. Make sure your VM is able to ping google.com before executing below command

yum install -y oracle-database-preinstall-19c

Set password for Oracle user

passwd oracle

Create Oracle home directory and give ownership to Oracle user

mkdir -p /u01/app/oracle/product/19.3/db_home
chown -R oracle:oinstall /u01
chmod -R 775 /u01

Setup Oracle user bash_profile

su - oracle
vi .bash_profile

Delete all and paste below. Make sure to change environment variables according to your environment

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
	. ~/.bashrc

# User specific environment and startup programs

export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/19.3/db_home

export ORACLE_SID=orcl

export LD_LIBRARY_PATH=\$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=\$ORACLE_HOME/jlib:\$ORACLE_HOME/rdbms/jlib
export NLS_LANG=american_america.al32utf8
export NLS_DATE_FORMAT="yyyy-mm-dd:hh24:mi:ss"


export PATH

Export bash profile

. .bash_profile

Install Oracle 19c Software

Download Oracle 19c and copy the 19c software file to ORACLE_HOME location and unzip. Start the run installer to perform installation


unzip -qo /softwares/LINUX.X64_193000_db_home.zip

DBCA Create 19c Database

Fire DBCA to create 19c database

#for GUI database creation

#for silent database creation
dbca -silent -createDatabase                            \
     -templateName General_Purpose.dbc                  \
