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
Install Oracle 19c Software
DBCA Create 19c Container Database
DBCA Create 19c Database (non-cdb)

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
fi

# User specific environment and startup programs

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

PATH=$PATH:$HOME/.local/bin:$ORACLE_HOME/bin

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

cd $ORACLE_HOME

unzip -qo /softwares/LINUX.X64_193000_db_home.zip

#for GUI installation
./runInstaller

#for silent installation
./runInstaller -ignorePrereq -waitforcompletion -silent      \

DBCA Create 19c Container Database

To create 19c container database along with multiple PDBs, use below

dbca -silent -createDatabase                            \
     -templateName General_Purpose.dbc                  \
     -gdbname ${ORACLE_SID} -sid  ${ORACLE_SID}         \
     -characterSet AL32UTF8                             \
     -sysPassword enterCDB#123                          \
     -systemPassword enterCDB#123                       \
     -createAsContainerDatabase true                    \
     -totalMemory 2000                                  \
     -storageType FS                                    \
     -datafileDestination /u01/${ORACLE_SID}            \
     -emConfiguration NONE                              \
     -numberOfPDBs 2                                    \
     -pdbName PDB                                       \
     -pdbAdminPassword enterPDB#123                     \
     -ignorePreReqs

Check all the containers inside the database

sqlplus / as sysdba

SELECT  NAME, OPEN_MODE, CDB FROM V$DATABASE;
SELECT CON_ID, NAME, OPEN_MODE FROM V$CONTAINERS;

DBCA Create 19c Database (non-cdb)

Oracle has stopped supporting non-cdb architecture but you can still create a non-cdb database

export ORACLE_SID=orcl
     
#for silent database creation
dbca -silent -createDatabase                            \
     -templateName General_Purpose.dbc                  \
     -gdbname ${ORACLE_SID} -sid  ${ORACLE_SID}         \
     -characterSet AL32UTF8                             \
     -sysPassword enterDB#123                           \
     -systemPassword enterDB#123                        \
     -createAsContainerDatabase false                   \
     -totalMemory 2000                                  \
     -storageType FS                                    \
     -datafileDestination /u01/${ORACLE_SID}            \
     -emConfiguration NONE                              \
     -ignorePreReqs -sampleSchema true
