Product Uninstallation Roadmap
The Oracle Fusion Middleware uninstaller removes software from the Oracle home directory that it starts from.
The following table summarizes the procedure and provides links to supporting documentation.
Table 5-1 Roadmap for Uninstalling Oracle Fusion Middleware Infrastructure
Stop Oracle Fusion Middleware.
Oracle recommends that you stop all servers and processes in your domain before you run the uninstaller.
Remove your database schemas.
Run Repository Creation Utility to remove your database schemas.
Remove the software.
Run the product uninstaller to remove Oracle Fusion Middleware Infrastructure.
Remove the Oracle home directory.
The uninstaller does not remove all files and folders from the Oracle home directory. After the uninstaller finishes, you must manually remove the Oracle home to complete your product removal.
Remove the program shortcuts on Windows operating systems.
The uninstaller does not remove the program shortcuts on your Windows operating system.
Remove your domain and application data.
The uninstaller does not remove data contained in your Domain home nor Application home directories, even if they are located inside the Oracle home. If necessary, you must remove these directories manually.
Stopping Oracle Fusion Middleware
Before you run the uninstaller, Oracle recommends that you stop all servers and processes associated with the Oracle home that you are going to remove.
For more about how to stop servers and processes, see Stopping an Oracle Fusion Middleware Environment in Oracle Fusion Middleware Administering Oracle Fusion Middleware.
Removing Your Database Schemas
Before removing the Oracle home, Oracle recommends that you run Repository Creation Utility to remove database schemas associated with a domain.
Each domain has its own set of schemas that a custom prefix uniquely identifies (see Understanding Custom Prefixes in Oracle Fusion Middleware Creating Schemas with the Repository Creation Utility). This set of schemas cannot be shared with any other domain (see Planning Your Schema Creation in Oracle Fusion Middleware Creating Schemas with the Repository Creation Utility).
If there are multiple sets of schemas on your database, be sure to identify the schema prefix associated with the domain you are removing.
For schema removal steps, see Dropping Schemas in Oracle Fusion Middleware Creating Schemas with the Repository Creation Utility.
Uninstalling the Software
You can use the uninstaller or perform a silent install.
To perform a silent (command-line) uninstallation, see Running the Oracle Universal Installer for Silent Uninstallation in Oracle Fusion Middleware Installing Software with the Oracle Universal Installer.
Starting the Uninstallation Program
The method you use to start the uninstallation program depends on your operating system: Windows or UNIX.
On UNIX operating systems, go to the
/oui/bin directory and enter command .
On Windows operating systems, use a file manager window to go to the
\oui\bin directory and double click on
Distribution to Uninstall
The installer shows the Distribution to Uninstall screen only if it detects more than one distribution in the Oracle home that you start the program from.
Select the distribution you want to uninstall from the drop-down list, then click Uninstall.
Beneath the drop-down list are the contents of the selected distribution, so you can verify that you are choosing to remove the correct distribution.
Navigating the Uninstallation Screens
The uninstallation program shows a series of screens in the order that the following table describes.
If you need additional help with any uninstallation screen, click the screen name.
Table 5-2 Uninstall Screens and Descriptions
Introduces you to the product uninstaller.
Shows the Oracle home directory and its contents that will be uninstalled. Verify that this is the correct directory.
Click Deinstall to begin removing the software.
Shows the progress of the uninstallation.
Opens when the uninstallation is complete. Review the information on this screen then click Finish to dismiss the uninstaller.
Removing the Oracle Home Directory Manually
After the uninstaller finishes, you must manually remove your Oracle home directory and any existing sub-directories that the uninstaller did not remove.
For example, if your Oracle home directory was
/home/Oracle/Products/Oracle_Home on a UNIX operating system:
cd /home/Oracle/Products rm -rf Oracle_Home
On a Windows operating system, if your Oracle home directory was
C:\Oracle\Products\Oracle_Home, use a file manager window and navigate to the
C:\Oracle\Products directory, then right-click on the
Oracle_Home folder and select Delete.
Removing Program Shortcuts on Windows Operating Systems
On Windows operating systems, you must also manually remove the program short cuts; the uninstaller does not remove them for you.
Go to the
C:\Program Data\Microsoft\Windows\Start Menu\Programs\Oracle\
Product directory. If you only have one product installed in your Oracle home, you can remove the
Oracle Home directory. If you have multiple products installed in your Oracle home, you must remove all products before removing the
Removing Your Domain and Application Data
If you will no longer use domain and application files, you can remove them.
To remove your domain and application data:
- Manually remove your Domain home directory.
For example, if your Domain home directory was
/home/Oracle/config/domains/infra_domainon a UNIX operating system:
cd /home/Oracle/config/domains rm -rf infra_domain
On a Windows operating system, if your Domain home directory was
C:\Oracle\Config\domains\infra_domain, use a file manager window and navigate to the
C:\Oracle\Config\domainsdirectory, then right-click on the
infra_domainfolder and select Delete.
- Manually remove your Application home directory.
For example, if your Application home directory was
/home/Oracle/config/applications/infra_domainon a UNIX operating system:
cd /home/Oracle/config/applications rm -rf infra_domain
On a Windows operating system, if your Application home directory was
C:\Oracle\Config\applications\infra_domain, use a file manager window and navigate to the
C:\Oracle\Config\applicationsdirectory, then right-click on the
infra_domainfolder and select Delete.
- Backup the
domain_registry.xmlfile in your Oracle home, then edit the file and remove the line associated with the domain you are removing. For example, to remove the
infra_domain, find the following line and remove it:
Save and exit the file when you are finished.
Reinstalling the Software
You can reinstall your software into the same Oracle home as a previous installation only if you have uninstalled the software by following the deinstallation instructions, including manually removing the Oracle home directory.
When you reinstall, you can then specify the same Oracle home as your previous installation.
Consider the following cases where the Oracle home is not empty:
Scenario: Installing in an Existing Oracle Home that Contains the Same Feature Sets
The installer warns you that the Oracle home you specified during the installation already contains the same software you are trying to install.
Select a different installation type. In this case, only feature sets that don't already exist in the Oracle home directory get installed.
Select a different Oracle home directory.
Scenario: Installing in an Existing, Non-Empty Oracle Home
Suppose that you have chosen to create your Domain home or Application home somewhere inside your existing Oracle home.
The deinstallation process doesn’t remove this data, so if you attempt to reinstall into the same Oracle home, the installer does not allow it.
Deinstall your software from the Oracle home as this topic describes, and then remove the Oracle home directory. After this is complete, you can reinstall and reuse the same Oracle home location, using the instructions in Installing the Infrastructure Software. You will need to re-create any domain or application data that was in the Oracle home.
Select a different Oracle home directory.
