Follow the instructions in this section to uninstall or reinstall Oracle Business Intelligence.
Oracle recommends that you always use the instructions in this section to remove the software. If you try to remove the software manually, you may encounter problems when you try to reinstall the software again at a later time. Following the procedures in this section ensures that the software is properly removed.
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.

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 bi_platform 12.2.1.4.0 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 Business Intelligence 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.

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 Linux or UNIX operating systems, enter the following commands:
cd /home/Oracle/product rm -rf ORACLE_HOME
After you uninstall the software, you must remove the domain and application data.
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.
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.
