This topic describes how to prepare your Windows® systems
for the installation of IBM® WebSphere® Application
Server products.
Before you begin
The installation uses an InstallShield MultiPlatform
(ISMP) wizard. You can use the graphical interface of the wizard.
You can also use the wizard in silent mode.
About this task
Preparing the
operating system involves such changes as allocating disk space and
installing patches to the operating system. IBM tests WebSphere Application
Server products on each operating system platform. Such tests verify
whether an operating system change is required for WebSphere Application Server products to
run correctly. Without the required changes, WebSphere Application Server products do
not run correctly.
Procedure
- Log on to a user ID that belongs to the administrator group.
Log on as a member of the administrator group to successfully
install the product. You cannot create Windows services
from a user ID that does not belong to the administrator group. The
creation of Windows services requires the
user to have the advanced user rights Act as part of the
operating system and Log on as a service.
During
the procedure, you can assign another ID or the one you are using
to install as the user who will log on the Windows service.
That user requires the advanced user right: Log on as a service.
However,
if you do not have this advanced user right or if the user ID that
is to log on the Windows service does not have
the advanced user right, the Installation wizard assigns the advanced
right to the user.
Tip: Windows service
creation can be disabled by launching the graphical interface from
the command line with the following additional option:
install.exe -OPT PROF_winserviceCheck="false"
- Optional: Download and install a Web browser.
You must install a Web browser if you want to use the launchpad application.
If your system does not have a default browser or the browser
has been corrupted or installed incorrectly, then you might experience
errors when trying to open various hyperlinks in the installation
wizard panels.
- Stop all WebSphere Application
Server-related Java™ processes
on the machine where you are installing the product.
- Stop any Web server process such as the IBM HTTP Server.
- Stop all instances of the process_spawner.exe program.
- Provide adequate disk space. The amount of disk
space required varies with the number of features or products installed.
If you are installing the product using the installation wizard, the
installation summary panel indicates the approximate amount of disk
space required based on the features and products you have selected.
Installing all features and products, including the centralized installation
manager (CIM) requires approximately 3 GB of disk space. Installing
all features and products without the CIM requires approximately 2
GB of disk space. This estimate includes the following products, components,
and features:
- Main application server product installation
- Profiles
- Sample applications
- IBM HTTP Server
- Web server plug-ins
- Application Client for WebSphere Application Server
- IBM Update Installer for WebSphere Software
If you plan to migrate applications
and the configuration from a previous version, verify that the application
objects have enough disk space. As a rough guideline, plan for space
equal to 110 percent of the size of the applications.
- Verify that prerequisites and corequisites are at the required
release levels.
Although the installation wizard checks
for prerequisite operating system patches with the prereqChecker application,
review the prerequisites on the Supported hardware and software Web
site if you have not done so already.
Refer to the documentation
for non-IBM prerequisite and corequisite products to learn how to
migrate to their supported versions.
- Download Windows Script 5.6 to create
Start menu items correctly on Windows 2000
and Windows XP.
Download Windows Script 5.6 from the following Microsoft® Web page: http://www.microsoft.com/ downloads/ details.aspx?
FamilyId= C717D943-7E4B-4622-86EB-95A22B832CAA.
- Verify that the Java 2
SDK on your copy of the product disk is functioning correctly.
If you created your own product disk from an ISO image or
by copying the actual disk, perform the following steps to verify
that the Java 2 SDK on the product CD-ROM
or DVD is working correctly.
- Change directories to the JDK\jre.pak\repository\package.java.jre\java\jre\bin directory
on the product disk. Type the following command:
cd disk_drive_D:\JDK\jre.pak\repository\package.java.jre\java\jre\bin
- Verify the version of the Java 2
SDK. Type the following command:
.\java -version
The
command completes successfully with no errors when the Java 2 SDK is intact.
Results
This procedure results in preparing the
operating system for installing the product.
What to do next
After verifying prerequisites, verifying the product disk,
and setting your installation goals, you can start installing. Use
one of the following links to open the installation procedure that
you require.
Install the application server product
on your operating system.
- Perform a custom installation.
The custom installation lets
you select features to install.
See Installing WebSphere Application Server.
- Perform a silent installation.
A silent installation requires
you to edit the example response file to contain all of your installation
choices. After creating a valid response file, issue the install command
with the silent parameter from a command window.
See Installing silently.
- Install additional features to an existing product.
After using
a custom installation to omit one or both of the optional features,
you can install the product again to add the features. Select a missing
feature to install it.
See Installing additional features on an existing base product.
- Upgrade a trial to the WebSphere Application Server
product.
After installing a trial, you can install the actual product
to upgrade the trial to the real product.
See Upgrading from the trial to the full product.
- Upgrade the Express product to the base WebSphere Application
Server product.
You can install the base product on a system where
the Express product is installed. The installation upgrades the Express
product to the base product.
See Upgrading from Express to the WebSphere Application Server product.
