This section describes how to uninstall Converged Application Server components in silent mode on all platforms.

Use silent mode to uninstall duplicate installations on multiple machines. In silent mode, you create and use a response_uninistall.rsp configuration file, and then specify it as a parameter at the command line. The program does not display any options during the uninstallation process.

To uninstall Converged Application Server components in silent mode:

1. Create a text file on your target system.
2. Add the following contents to your file:

   [ENGINE]
   
   #DO NOT CHANGE THIS.
   Response File Version=1.0.0.0.0
    
   [GENERIC]
    
   #This will be blank when there is nothing to be de-installed in distribution level
   SELECTED_DISTRIBUTION=Oracle Communications Converged Application Server~8.0.0.0.0
    
   #The oracle home location. This can be an existing Oracle Home or a new Oracle Home
   ORACLE_HOME=Oracle_home
   

   where SELECTED_DISTRIBUTION is set to the component to uninstall. For Converged Application Server, set SELECTED_DISTRIBUTION to Oracle Communications Converged Application Server~8.0.0.0.0.

3. Save the file with the name response_uninstall.rsp.
4. Go to the Oracle_home/oui/bin directory and enter the following in a command window:

   ./deinstall.sh -silent -responseFile ResponseFile
   

   where ResponseFile is the full path and name of the response_uninstall.rsp file. For example, Oracle_home/oui/bin/response_uninstall.rsp.

   The uninstallation process completes with no prompts.

If the uninstallation procedure completes successfully, you see a response similar to the following:
