Modes of installation and uninstallation

This topic describes the three modes that you can use during installation and uninstallation, both for the runtime components and the Message Brokers Toolkit:

In this topic installer and uninstaller, used in example commands, denote where you must enter the specific names of the installation or uninstall wizard. For the names of the installation and uninstall wizards, and full details of these tasks, see Installation Guide and Uninstalling.

Graphical mode

The installation and uninstallation wizards start in graphical mode if you invoke them with no options (this is the default mode). The wizards guide you through the installation or uninstallation process with a series of dialogs that present options and defaults. You can accept the default values, or change them to suit your environment and requirements.

This mode provides the highest level of information and guidance to help you complete an installation. Use this mode when you are unfamiliar with the product, or if you want to monitor the installation or uninstallation progress.

If you click Cancel before the Install Progress or Uninstall Progress panel appears, you can exit the setup. If you choose to exit, your system returns to its state before launching the wizard. However, if you cancel the installation wizard after installation or uninstallation has completed, and the final summary panel is displayed, your system is not restored to its previous state: the installation wizard stops immediately. If you want to remove any program that has been installed, you must invoke the uninstallation program.

When you use the wizards, you might have to wait a few seconds to move to the next panel after clicking Next >. Progress is not always displayed on all panels. If you click Next > twice, you might skip an entire panel. To ensure the installer or uninstaller is progressing, you can monitor your CPU usage: CPU usage increases greatly during both installation and uninstallation.

Console mode

Console mode presents a text based interface with which you interact in a command window. It presents the same options as the graphical interface, and you can choose values and navigate through the process using the keyboard only.

Use this mode if you prefer a command line interface to a graphical based interface, or if you require additional audible information for visually-impaired users. When you specify an accessibility option, the wizard generates modified and additional information about its processing that is more appropriate for screen reader software such as JAWS.

Use these prompts to navigate through the installation:
  • 1 Move to the next panel
  • 2 Return to the previous panel
  • 3 Cancel and terminate the install program
  • 4 Redisplay the current screen

The default option is always displayed within brackets, for example [1]. If this is the correct choice, press Enter to continue.

Action Invocation
Invoke the installation wizard in console mode. Messages are displayed on the console during installation. installer -console
Invoke the installation wizard in console mode with additional audible information for visually-impaired users. (This option sets the installation automatically to console mode so you do not need the -console option as well.) installer -accessibility

Silent mode

If you invoke a silent installation or uninstallation, the wizard runs without any interaction. In this mode, the process is completed with default options, or according to a predefined set of options, as described below.

Use this unattended interface for automated installations or uninstallations over a large number of identical systems.

Silent mode does not provide any feedback to the caller, therefore you must check the log to determine if the action was successful.

You can perform a silent installation:
  • With default settings. For example, for installation this results in these actions:
    • Check that prerequisite software is installed (runtime components only).
    • Install to the default directory.
    • Install all selectable features.

    Because the installation wizard for the runtime components checks for prerequisite software in silent mode, the program fails if the prerequisite software is not already installed. You can override this check if you use a response file (see Using response files), or include the appropriate parameter with a non-default value on the command invocation.

    To run a default silent installation, specify the -silent option on the command. For example, to install runtime components on Linux (x86 platform), enter the following command:
    setuplinuxia32 -silent 
  • With one or more non-default settings. If you want the installation wizard to use non-default values for one or more values, you can either specify non-default options on the command invocation or specify a response file, as described in Using response files.

    A sample response file for installation of the runtime components is provided in the sample-scripts directory of root CD directory. It includes detailed information about the options that you can change, and the values you must enter to change them. You can tailor this file to your requirements, or you can generate a new response file, as described below.

    To run a tailored silent installation using a response file called response1.txt, specify the -silent option and the filename on the installation command. For example, on Linux (x86 platform), enter the following command:
    setuplinuxia32 -silent -options response1.txt
