Ubuntu Linux Install Oracle Database XE Server

To install the Oracle Database XE (Express Edition) server on an Ubuntu Linux system, you can follow these steps:

1. Download the Oracle Database XE installation package from the Oracle website. The installation package is a .deb file that can be installed using the dpkg package manager.

sudo apt-get install libaio1

3. Install the Oracle Database XE server by running the following command:

sudo dpkg -i oracle-xe_18c-1.0-1_amd64.deb

Replace oracle-xe_18c-1.0-1_amd64.deb with the name of the .deb file that you downloaded.

4. Run the Oracle Database XE configuration script by running the following command:

sudo /etc/init.d/oracle-xe configure

This will prompt you to enter a password for the Oracle Database XE system user (system), set the port number for the Oracle Database XE listener (1521), and set the password for the Oracle Database XE database administrator (sys).

5. Start the Oracle Database XE server by running the following command:
