Uninstalling EPM System Products

When you uninstall Oracle Enterprise Performance Management System products, EPM System Uninstaller removes the binaries from the installation location. Use uninstall when you want to completely remove components that are not in use any more in any instance in the deployment.

Caution:

When you uninstall EPM System products, EPM System Uninstaller removes everything from the installation directory. Before you uninstall, be sure to back up any files you want to keep. For information about backing up files, see Oracle Enterprise Performance Management System Backup and Recovery Guide.

To uninstall EPM System products:

Ensure that no EPM System processes are running.
Choose a method to launch the uninstaller:
- (Windows) In epm_oracle_home/uninstall, double-click uninstall.cmd.
- (Windows) In the Windows Control Panel, select Oracle EPM System to remove/uninstall.
- (Windows) From a Windows console, change to epm_oracle_home/uninstall/, and then enter uninstall.cmd.
- From the Start menu, select Programs, then Oracle EPM System, and then Uninstall EPM System.
- (Linux) Change to the /uninstall directory and enter ./uninstall.sh.
- (Linux) Change to the /uninstall directory and enter ./uninstall.sh —console.
Exit other programs before you continue, and then click or select Next.
Select the products to uninstall, and then click or select Next. All components on the same tier of the selected products are uninstalled.

For example, if you uninstall any Oracle Hyperion Financial Management web component, EPM System Uninstaller uninstalls all Financial Management web components.

All installed products are selected by default. Select "Uncheck all" to clear the selections for all products, and then select only the products you want to uninstall.
Specify whether you want to delete all the files and directories in the EPM Oracle Home directory.

If you select this option, data and customized files are deleted.
Confirm the products to uninstall, and then click or select Next.

EPM System Uninstaller displays progress incrementally as each assembly's uninstallation is complete.

Note:

To cancel the uninstallation, click or select Cancel. When you select Cancel, EPM System Uninstaller stops the uninstallation of the current assembly and rolls that assembly back to an installed state. It does not undo uninstallations for assemblies that were already uninstalled.

EPM System Uninstaller indicates the success or failure of the uninstallation. If any part of the uninstallation failed, EPM System Uninstaller notes which assembly failed to uninstall. Check the log files for more information about the errors. You can find the log files in epm_oracle_instance/diagnostics/logs/install. There is a log file for each assembly, named product-install.log; for example, hss-install.log.
Click or select Finish to close EPM System Uninstaller.
On Windows, if you uninstalled Oracle HTTP Server, you must reboot to completely remove the installation. This step is required if you plan to reinstall.
Reboot after uninstalling EPM System products.

When uninstalling a client, select Delete common components in the Setup Type window only if you are deleting all EPM System clients that are installed on a machine. If multiple EPM System clients are installed on the same machine and you are deleting only one client, deselect Delete common components.

Performing a Silent Product Uninstallation

Silent uninstallations automate the process so that you can uninstall EPM System products on multiple computers without manually specifying uninstallation settings on each machine.

To uninstall EPM System products on multiple computers using the same uninstallation options, record a response file during installation. You can then run a silent uninstallation from the command line, using the options that were saved in the response file.

To run a silent uninstallation:

Copy the response file that you created during installation to the machine on which you want to run the uninstallation. You can also copy the file to a network drive that is accessible from the machines on which you want to uninstall.

For information about recording a response file during installation, see "Performing Silent Installations" in the Oracle Enterprise Performance Management System Installation and Configuration Guide.
From the command line, enter a command:

For Windows:
```
uninstall.cmd -silent filename
```
For Linux:.
```
uninstall.sh -silent filename
```
The uninstallation runs in the background.
