Stopping Oracle Fusion Middleware

Before running the Uninstall Wizard, Oracle recommends that you stop all servers and processes associated with the Oracle home you are going to remove.

See Stopping an Oracle Fusion Middleware Environment in Administering Oracle Fusion Middleware.

Removing Your Database Schemas

Before you remove the Oracle home, Oracle recommends that you run the Repository Creation Utility (RCU) to remove database schemas associated with this domain.

Each domain has its own set of schemas, uniquely identified by a custom prefix. For more information about custom prefixes, see About Custom Prefixes in Creating Schemas with the Repository Creation Utility. This set of schemas cannot be shared with any other domain. For more information about creating schemas with the RCU, see Planning Your Schema Creation in 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 that you are removing.

For schema removal steps, see Dropping Schemas in Creating Schemas with the Repository Creation Utility.

Starting the Uninstall Wizard

To start the Uninstall Wizard:

1. Change to the following directory:
   (UNIX) ORACLE_HOME/oui/bin
   (Windows) ORACLE_HOME\oui\bin
2. Enter the following command:
   (UNIX) ./deinstall.sh
   (Windows) deinstall.cmd

Selecting the Product to Uninstall

Because multiple products exist in the Oracle home, ensure that you are uninstalling the correct product.

After you run the Uninstall Wizard, the Distribution to Uninstall screen opens. From the dropdown menu, select WebCenter Sites 12.2.1.3.0 and click Uninstall. The uninstallation program shows the screens listed in Navigating the Uninstall Wizard Screens.

Note:

You can uninstall Oracle Fusion Middleware Infrastructure after you uninstall Oracle WebCenter Sites software by running the Uninstall Wizard again. Before doing so, make sure that there are no other products using the Infrastructure; those products will no longer function once the Infrastructure is removed. You will not encounter the Distribution to Uninstall screen if no other software depends on Oracle Fusion Middleware Infrastructure. See Uninstalling Oracle Fusion Middleware Infrastructure in Installing and Configuring the Oracle Fusion Middleware Infrastructure.

Navigating the Uninstall Wizard Screens

The Uninstall Wizard shows a series of screens to confirm the removal of the software.

Removing the Oracle Home Directory Manually

After you uninstall the software, you must manually remove your Oracle home directory and any existing subdirectories that the Uninstall Wizard did not remove.

For example, if your Oracle home directory is /home/Oracle/product/ORACLE_HOME on a UNIX operating system, enter the following commands:

 cd /home/Oracle/product
 rm -rf ORACLE_HOME

On a Windows operating system, if your Oracle home directory is C:\Oracle\Product\ORACLE_HOME, use a file manager window and navigate to the C:\Oracle\Product directory. Right-click on the ORACLE_HOME folder and select Delete.

Removing the Program Shortcuts on Windows Operating Systems

On Windows operating systems, you must also manually remove the program shortcuts; the Deinstallation Wizard does not remove them for you.

To remove the program shortcuts on Windows:

1. Change to the following directory: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Oracle\ORACLE_HOME\Product

2. If you only have one product installed in your Oracle home, delete the ORACLE_HOME directory. If you have multiple products installed in your Oracle home, delete all products before you delete the ORACLE_HOME directory.

Removing the Domain and Application Data

After you uninstall the software, you must remove the domain and application data.

To remove the domain and application data:

1. Manually remove your Domain home directory. For example:

   On a UNIX operating system, if your Domain home directory is /home/Oracle/config/domains/wcs_domain, enter the following command:

   cd /home/Oracle/config/domains

   rm -rf wcs_domain

   On a Windows operating system, if your Domain home directory is C:\Oracle\Config\domains\wcs_domain, use a file manager window and navigate to the C:\Oracle\Config\domains directory. Right-click on the wcs_domain folder and select Delete.

2. Manually remove your Application home directory. For example:

   On a UNIX operating system, if your Application home directory is /home/Oracle/config/applications/wcs_domain, enter the following commands:

   cd /home/Oracle/config/applications

   rm -rf wcs_domain

   On a Windows operating system, if your Application home directory is C:\Oracle\Config\applications\wcs_domain, use a file manager window and navigate to the C:\Oracle\Config\applications directory. Right-click on the wcs_domain folder and select Delete.

3. Back up the domain_registry.xml file in your Oracle home, then edit the file and remove the line associated with the domain that you are removing. For example, to remove the wcs_domain, find the following line and remove it:

   <domain location="/home/Oracle/config/domains/wcs_domain"/>
   

   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 uninstalled the software by following the instructions in this section, including manually removing the Oracle home directory.

When you reinstall, you can then specify the same Oracle home as your previous installation.

If ODI is installed again in the same location where it was previously deleted, delete the entire Oracle Home where it was previously installed.

Consider the following cases where the Oracle home is not empty:

• Installing in an existing Oracle home that contains the same feature sets.

  The installer warns you that the Oracle home that you specified during installation already contains the same software you are trying to install.

• Installing in an existing, non-empty Oracle home.

  For example, suppose you chose to create your Domain home or Application home somewhere inside your existing Oracle home. This data is not removed when you uninstall a product, so if you try to reinstall into the same Oracle home, the installer does not allow it. Your options are:

  • Uninstall your software from the Oracle home (as this section describes) and then remove the Oracle home directory. After you uninstall the software and remove the Oracle home directory, you can reinstall and reuse the same Oracle home location. Any domain or application data that was in the Oracle home must be re-created.

  • Select a different Oracle home directory.
