Removing an RPM-based Oracle Database Installation

Use this procedure to remove and deinstall a database installed using the yum command.

1. Log in as root.
2. Run the following command to remove the RPM-based database installation:

   # yum -y remove oracle-database-ee-18c

If the yum command detects other configured components in the Oracle home such as databases or listeners, then it stops the deinstallation process. A message is displayed that instructs you to remove the configured components manually. To remove these configured components:

1. Login as the Oracle Database installation owner user (oracle).

2. To remove any database associated with your installation, use Oracle Database Configuration Assistant (Oracle DBCA).

   $ cd $ORACLE_HOME/bin 
   $ ./dbca
   
   

3. To remove any listeners associated with your installation, run Oracle Net Configuration Assistant (Oracle NETCA).

   $ cd $ORACLE_HOME/bin 
   $ ./netca

4. Log in as root and run the yum command again to remove the rpm-based database installation.

   # yum -y remove oracle-database-ee-18c
