How can Oracle delete a database?

To remove an Oracle database, you can follow these steps:

Firstly, make sure you have an Oracle user account with administrator privileges and log in to the database server.

2. Open the command line terminal or SQL Plus interface and log in to the database using an administrator account. For example:

sqlplus / as sysdba

3. Input the following command in the SQL Plus interface to shut down the database:

shutdown immediate

After confirming that the database is closed, enter the following command to delete the database:

startup mount exclusive restrict;
drop database;

5. Enter the confirmation information as prompted and wait for the database deletion to be completed.

Please be aware that deleting a database is a risky operation, as it cannot be recovered once executed. Before performing the deletion, make sure to have backed up any important data.
