These instructions are a quick and simple way to set up Oracle for experimenting - it is no no way fit for production use. This assumes familiarity with Amazon EC2 - you could also use RHEL 7.9 installed another way but I have not tested that.
Start an EC2 Instance in a region of your choice (Ideally the same one where you will be running MongoDB Atlas). Oracle XE has limitation on hardware and data size so it should be
- 2 CPU, 4GB RAM (t3.medium instance)
- OS: RHEL 7.9 64 bit (RHEL-7.9_HVM-20211005-x86_64-0-Hourly2-GP2 in COmmunity AMIs)
- 25GB gp3 root disk (Change on Add Storage screen from 10GB gp2)
Log onto your Instance using ssh, the command I used is below, modify for your key and IP
ssh -i ~/.ssh/johnpage.pem ec2-user@63.32.235.119

Install Oracle Prerequisites
sudo yum -y localinstall oracle-database-preinstall-18c-1.0-1.el7.x86_64.rpm
Setup the database
sudo yum install -y oracle-database-xe-18c-1.0-1.x86_64.rpm
sudo /etc/init.d/oracle-xe-18c configure
You are prompted for a password here, this is used for the various initial system accounts SYS, SYSTEM, PDBADMIN - set a password here you can remember and type.
This part can take 10-20 minutes.
When complete you will see
Database creation complete. For details check the logfiles at:
/opt/oracle/cfgtoollogs/dbca/XE.
Database Information:
Global Database Name:XE
System Identifier(SID):XE
Look at the log file "/opt/oracle/cfgtoollogs/dbca/XE/XE.log" for further details.
Connect to Oracle Database using one of the connect strings:
Pluggable database: ip-172-31-32-141.eu-west-1.compute.internal/XEPDB1
Multitenant container database: ip-172-31-32-141.eu-west-1.compute.internal
Use https://localhost:5500/em to access Oracle Enterprise Manager for Oracle Database XE
Use the following commands to set up your paths then connect.
export ORACLE_HOME=/opt/oracle/product/18c/dbhomeXE/
export PATH=${PATH}:/opt/oracle/product/18c/dbhomeXE/bin
Log in with
sqlplus sys/YOUPASSWORD@$(hostname)/XEPDB1 as sysdba
replace YOURPASSWORD with the password you set earlier and verify you can log in and get an SQL> prompt
