Welcome to this comprehensive guide on installing Oracle Database 19c on Oracle Linux 7. In this tutorial, we will cover the prerequisites, software installation, and database creation using DBCA.

1. Prerequisites

Before starting the installation, ensure your system meets the following requirements:

  • At least 8GB of RAM
  • minimum 50GB of swap space (recommended)
  • Update the system using yum update

Run the following command to install the preinstall package:

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

2. Creating Directories

Create the necessary directories for Oracle software ownership:

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

3. Unzipping the Software

Login as the oracle user and unzip the downloaded file directly into the Oracle Home directory:

su - oracle
cd /u01/app/oracle/product/19.0.0/dbhome_1
unzip -q p29517242_190000_Linux-x86-64.zip

4. Launching the Installer

Once unzipped, run the installer to start the graphical wizard:

./runInstaller
Note: Ensure you have X11 forwarding enabled if you are running this from a remote SSH session.

Summary

This concludes the basic setup. In the next part, we will discuss creating a container database (CDB) and pluggable databases (PDB).
