Download link: https://www.oracle.com/database/free/...

Oracle Database Free CPU Limitations:
Oracle Database Free limits itself automatically to two cores for processing. For example, on a computer with 2 dual-core CPUs (four cores), if a large number of database clients try to simultaneously run CPU-intensive queries, then Oracle Database Free will process the queries at the rate of just two cores even if more CPU capacity is available.

Oracle Database Free Installation and Runtime Restrictions:
Oracle Database Free restricts itself to only one installation per logical environment. The logical environment can either be a virtual host such as a VM or container, or a physical host. If you attempt to start more than one Oracle Database Free installation in such a logical environment, then an ORA-00442: Oracle Database Free single instance violation error is displayed and your database will not start.

Oracle Database Free User Data Limitations:
The maximum amount of user data in Oracle Database Free cannot exceed 12 GB. If the user data grows beyond this limit, then the system displays an ORA-12592 error.

Oracle Database Free RAM Limitation:
The maximum amount of RAM for Oracle Database Free cannot exceed 2 GB, even if more is available.

Other Requirements:
A static ip address was already set to access the database in host machine.
SQL Developer installed in host machine to access the database.
Linux User "oracle" is created to install and configure the database.
Open the Oracle database port in Firewall (if you are using VM or try to access the database outside the network) by executing the command "firewall-cmd --add-port=1521/tcp --permanent"
