6.1 Removing Oracle Software Files

To remove Oracle software by using Oracle Universal Installer, you must perform the following steps:

Note:

Always use Oracle Universal Installer to remove Oracle software. Do not delete any Oracle home directories without first using Oracle Universal Installer to remove the software.

If necessary, log in as the oracle user:
```
$ su - oracle
```
Set the ORACLE_HOME environment variable to specify the path of the Oracle home that you want to remove:
- Bourne, Bash, or Korn shell:
```
$ ORACLE_HOME=oracle_home_path
$ export ORACLE_HOME
```
- C shell:
```
$ setenv ORACLE_HOME oracle_home_path
```
Start Oracle Universal Installer by entering the following command:
```
$ORACLE_HOME/oui/bin/runInstaller
```
On the Welcome screen, click Deinstall Products.

The Inventory screen lists all the Oracle homes on the system and the products installed in each Oracle home.
On the Inventory screen, select the Oracle home containing the products that you want to remove.
If you want to delete specific products, then select them in the tree window.
Click Remove.

Oracle Universal Installer displays a confirmation screen prompting you to confirm that you want to remove the selected products and their dependent components.
Click Yes.

Oracle Universal Installer displays a progress indicator as it removes the software.
