J2EE Policy Agents Guide

Appendix A  
Silent Installation

In addition to the GUI installation and the Command Line installation, you can do a silent installation of J2EE Policy Agents. This appendix provides steps for doing that.

About Silent Installation/Uninstallation

Silent installation/uninstallation provides a means for scripting the installation/uninstallation. When you perform a silent installation/uninstallation, you use a state file, to provide all the answers that you would normally supply to the installation/uninstallation program interactively. This saves time and is useful when you want to install/uninstall multiple instances of Sun ONE Identity Server Policy Agent using the same parameters in each instance.

Silent installation is a simple two-step process. First, you generate a state file that records the installation/uninstallation process and all the inputs you provide. Then you run the installation/uninstallation program with the state file as the input source.

Generating a State File for Installation

To generate a state file, do the following:

  1. Change to the directory where the installation program is located.
  2. Enter one of the following commands if you are running the GUI installation program.

    3. If you are on Solaris, HP-UX, AIX, or Linux, enter:

    # ./setup.sh -saveState StateFile

    If you are on Windows, enter:

    C:\> setup.bat -saveState StateFile

    You can give a name of your choice to the state file. Follow the instructions as specified in the section "Using the GUI Installation Program."

  3. Alternatively, you can enter one of the following commands if you are using the command line installation program.

    4. If you are on Solaris, HP-UX, AIX, or Linux, enter:

    #./setup.sh -nodisplay -saveState stateFile

    If you are on Windows, enter:

    C:\setup.bat -nodisplay -saveState stateFile

    You can give a name of your choice to the StateFile. Follow the instructions as specified in the section "Using the Command-Line Installation Program."

  4. Proceed through the installation. Your answers to the prompts are recorded in the state file. When the installation is complete, the state file is created in the same directory where the installation program is located.

    5. Note

    When generated, a state file will have read permissions for all users. However, because the state file contains clear text passwords, it is recommended that you change the file permissions to restrict read/write access to the user root.

Using the State File for Silent Installation

To perform silent installation using the state file, do the following.

  1. Change to the directory where the installation program and the state file are located.
  2. Enter the following command:

    3. If you are on Solaris, HP-UX, AIX, or Linux, enter:

    # ./setup.sh -nodisplay -noconsole -state StateFile

    If you are on Windows, enter:

    C:\> setup.bat -nodisplay -noconsole -state StateFile

    The installation takes place hidden from your view. On completion, the program exits automatically and displays the prompt.

    Note

    The installation program doesn’t validate inputs or the state in the silent installation. You must ensure that the proper environment exists before performing the silent installation.

Generating a State File for Uninstallation

To generate a state file for uninstallation, do the following.

  1. Change to the agent installation directory, where the uninstallation program is located.
  2. Enter one of the following commands if you are using the GUI installation program:

    3. If you are on Solaris, HP-UX, AIX, or Linux, enter:

    # ./uninstall.sh -saveState StateFile

    If you are on Windows, enter:

    C:\> uninstall.bat -saveState StateFile

    You can give a name of your choice to the state file. Follow the instructions as specified in the section "Using the GUI Uninstallation Program" to proceed with the uninstallation.

  3. Alternatively, you can enter one the following commands if you are using the command line installation program.

    4. If you are on Solaris, HP-UX, AIX, or Linux, enter:

    #./uninstall.sh -nodisplay -saveState stateFile

    If you are on Windows, enter:

    C:\> uninstall.bat -nodisplay -saveState stateFile

    You can give a name of your choice to the state file.

  4. Proceed through the uninstallation program as explained in "Using the GUI Uninstallation Program". Your answers to the prompts are recorded in the state file. When uninstallation is complete, the state file is created in the same directory where the uninstallation program is located.

    5. Note

    When generated, a state file will have read permissions for all users. However, because the state file contains clear text passwords, it is recommended that you change the file permissions to restrict read/write access to the user root.

Using the State File for Silent Uninstallation

To perform silent uninstallation using the state file, do the following:

  1. Change to the agent installation directory where uninstallation program and the state file are located.
  2. Update the state file with the ID of the uninstallation program class as follows:

    3. If you are on Solaris, HP-UX, AIX, or Linux, enter:

    #./uninstall.sh -id

    If you are on Windows, enter:

    C:\> uninstall.bat -id

    This command will print the id of the uninstallation program class file.

  3. Replace the ID in the state file with this ID.

    4. Note

    The state file id for the uninstallation program will change every time because the installation program creates a new class file for uninstallation. While running uninstallation program in the silent mode, you must ensure that the id in the class file matches the id of the uninstallation class.

  4. Begin the uninstallation process by using one of the following commands:

    5. If you are on Solaris, HP-UX, AIX, or Linux, enter:

    # ./uninstall.sh -nodisplay -noconsole -state StateFile

    If you are on Windows, enter:

    C:\> uninstall.bat -nodisplay -noconsole -state StateFile

    The uninstallation takes place hidden from your view. On completion, the program exits automatically and displays the prompt.

    Note

    The uninstallation program doesn’t validate inputs or the state in the silent uninstallation. The user must take care to ensure that the proper environment exists before performing the silent mode uninstallation
