To remove Oracle Database Express Edition (Oracle XE) from an Ubuntu Linux system, you can use the apt-get command with the remove and purge options and the oracle-xe package. The apt-get command is a package management tool that is used to install, remove, and manage packages on Ubuntu systems. The oracle-xe package is the package that contains the Oracle XE software.
Here's the command to remove Oracle XE from an Ubuntu Linux system:
sudo apt-get remove --purge oracle-xeSource:wwal.wutturi.com
This command will remove the Oracle XE software and its dependencies from the system and delete the configuration files. It will also remove any packages that were installed as dependencies of Oracle XE and are no longer needed.
Keep in mind that this command will only remove the Oracle XE software and its dependencies from the system. It will not delete the data files or the Oracle XE database itself. If you want to delete the database and the data files, you will need to manually delete them from the file system.
For more information on the apt-get command and how to use it on Ubuntu Linux systems, you can refer to the apt-get documentation or the Ubuntu documentation.
Alternatively, you can also use the dpkg command to remove Oracle XE from an Ubuntu Linux system. The dpkg command is a low-level package management tool that is used to install, remove, and manage packages on Ubuntu systems. To remove Oracle XE using the dpkg command, you can use the following command:
sudo dpkg --purge oracle-xe
This command will have the same effect as the apt-get command, but it may be more time-consuming and less user-friendly. The apt-get command is generally preferred over the dpkg command for managing packages on Ubuntu systems.
For more information on the dpkg command and how to use it on Ubuntu Linux systems, you can refer to the dpkg documentation or the Ubuntu documentation.
