Installation methods

Select the appropriate installation method for environment. You can use either a graphical interface program, console mode, or a response file for a silent installation.
GUI

The graphical user interface program gathers essential information, such as host name and node, and then performs the installation. Some OSs do not support a graphical user interface.

Console mode

The console mode is a textual representation of the graphical user interface program. Enter a number that corresponds to selection and then press Enter to proceed through the installation.

Silent installation

The silent installation uses a response file to supply installation options without user interaction. Use this option when installing or uninstalling WebSphere Portal on multiple machines with a similar setup. To configure the installation, change the options in the response file before issuing the installation task.

Installation notes: Read the following information before installing:

• Applies to all installation methods:

  • Before you begin installing or uninstalling, disable or turn off any screen saver software that is running on the machine. This software can affect the ability of the machine to connect to the network and sometimes interfere with the operation of the installation program.

  • The installation program verifies the OS and its prerequisites, available disk space, and any required software prerequisites prior to installation.

  • You cannot install two instances of the server at the same time, even if you are installing to different directories. You must install each server completely before installing the next one.

  • The installation directory that you specify must NOT contain any files.

  • The installation directory that you specify must NOT contain the following characters:
    ~

    !

    @

    #

    $

    %

    ^

    &

    *

    (

    )

    _

    +

    {

    }

    |

    <

    >

    ?

    `

    =

    [

    ]

    ;

    '

    ,

    "

• Applies to both the graphical user interface and the console mode methods:
  If the host name displays incorrectly, for example serve1.server1.rtp.raleigh.ibm.com, correct the information; for example, change serve1.server1.rtp.raleigh.ibm.com to server1.rtp.raleigh.ibm.com. This behavior is only found when the installation is run on a Windows™ server where an instance of Microsoft Exchange server is already installed.

• Applies only when using the graphical user interface:
  When a dialog is displayed and enter text, use either pointing device or press the TAB key to move between the entry fields.

32 bit installation on 64 bit OS

Choose one of the following methods to install a 32 bit installation on a 64 bit OS:

Method	Instructions
Manual installation	Manually install the 32- bit IBM WAS product. Then install WebSphere Portal into the existing WAS installation.
Command-line installation	Enter the install.bat|sh -W defaults.force32bit=true command to install a 32- bit WAS and WebSphere Portal on a 64- bit OS. This command is not supported on zLinux™ and IBM i OSs. Important for IBM i: If you use IBM i and a J9 32- bit JVM, you can enter the -W enableClassicJVM.active=false parameter to install the server with J9 32- bit JVM instead of Classic 64- bit JVM.
