10 Uninstalling OCECAS

This chapter describes how to uninstall Oracle Communications Evolved Communications Application Server (OCECAS) and its components.

Uninstalling OCECAS in GUI Mode

To uninstall OCECAS components in GUI mode, perform the following on each machine in your OCECAS system:

  1. Log in to the target system.

  2. Manually shut down all services and WebLogic Server.

  3. Perform this step only on the machine that hosts your Management Domain:

    Go to the Ocecas_home directory, and enter the following command:

    ./root.sh -d remove
    
  4. Go to the Ocecas_home/oui/bin directory, and enter the following command:

    ./deinstall.sh
    
  5. If you have multiple Oracle products installed in your Oracle Inventory directory (oraInventory), the Distribution to Uninstall screen appears.

    Perform the following to specify the Oracle product to uninstall:

    1. From the Select Distribution to Uninstall list, select Evolved Communications Application Server~7.0.0.0.0.

    2. Click Uninstall.

  6. From the Welcome screen, click Next.

    The Deinstallation Summary screen appears.

  7. Verify that the list of feature sets to uninstall is correct.

    To save the information to a response file so you can uninstall the components later, click Save Response File and specify the name and location of the response file.

  8. Click Deinstall.

    The Deinstallation Progress screen appears, and a progress bar indicates the status of the uninstallation process.

  9. When the uninstallation process is complete, click Next.

    The Deinstallation Complete screen appears.

  10. Click Finish.

    The uninstaller exits.

Uninstalling OCECAS in Silent Mode

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 OCECAS components in silent mode, perform the following on each machine in your OCECAS system:

  1. Log in to the target system.

  2. Manually shut down all services and WebLogic Server.

  3. Create a text file.

  4. Add the following contents to your text 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=Evolved Communications Application Server~7.0.0.0.0
     
    #The oracle home location. This can be an existing Oracle Home or a new Oracle Home
    ORACLE_HOME=Ocecas_home
    

    where SELECTED_DISTRIBUTION is set to the component to uninstall. This parameter is required only if multiple applications are installed in the Oracle Inventory directory (oraInventory). For OCECAS, set SELECTED_DISTRIBUTION to Evolved Communications Application Server~7.0.0.0.0.

  5. Save the text file with the name response_uninstall.rsp.

  6. Perform this step only on the machine that hosts your Management Domain:

    Go to the Ocecas_home directory, and enter the following command:

    ./root.sh -d remove
    
  7. Go to the Ocecas_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, Ocecas_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:
