This topic describes how to prepare your Windows systems for the
installation of IBM WebSphere Application Server Version 6.x 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.
Silent mode is a command
line invocation with a parameter that identifies an options response file.
Edit the options response file before installing.
If
you encounter a problem such as needing more temporary space or missing prerequisite
packages on your operating system, cancel the installation, make the required
changes, and restart the installation.
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.
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 the latest supported
version of Internet Explorer so that you can use the launchpad on the product
disc. Download Internet Explorer 6 from the following location:
http://www.microsoft.com/windows/ie/default.mspx
- Optional: Download and install Mozilla 1.7.5 or later.
If you plan to use the Mozilla browser, install the 1.7.5 version
to avoid a known problem that causes two browser windows to open when using
the launchpad.bat script. This problem is caused by a known bug with the Mozilla
-CreateProfile feature. See bugzilla bug 249585 for more information.
- 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.
Attention:
The Network Deployment product requires
the following disc space:
- 730 MB for the C:\Program Files\IBM\WebSphere\AppServer directory
before creating profiles
The installation root directory includes the core
product files. This size does not include space for profiles or applications.
Profiles require 40 MB of temp space in addition to the sizes shown. Profiles
have the following space requirements:
- 30 MB for the Deployment manager profile
This size does not include space for Sample applications
that you might install. The size also does not include space for applications
that you might deploy.
- 200 MB for an Application Server profile with the Sample applications
This size does not include space for applications
that you might develop and install.
- 10 MB for an unfederated custom profile
This size does not include space for applications
that you might develop and install. The requirement does include space for
the node agent. However, you must federate a custom profile to create an operational
managed node.
After federating a custom profile,
the resulting managed node contains a functional node agent only. Use the
deployment manager to create server processes on the managed node.
- 100 MB for the C:\temp directory
The temporary directory is the working directory
for the installation program.
- 830 MB total requirement
This amount is the total space requirement when installing
the product from the disc and when not installing service. Installing profiles
requires more space.
The following space is required for the
IBM HTTP Server product:
- 110 MB for the C:\Program Files\IBM HTTP Server directory
The IBM HTTP Server product requires this space.
- 25 MB for the C:\Program Files\ibm\gsk7 directory
The IBM Global Security Kit (GSKit) requires this
space.
The following space is the maximum amount
that is required for the Web server plug-ins for WebSphere Application Server:
- 200 MB for the C:\Program Files\IBM\WebSphere\Plugins directory
The Web server plug-ins require this space.
- 25 MB for the C:\Program Files\ibm\gsk7 directory
The IBM Global Security Kit (GSKit) requires this
space.
The following space is required for the
Application Client for WebSphere Application Server:
- 150 MB for the C:\Program Files\IBM\WebSphere\AppClient directory
The amount of space required to install the application
clients is actually less than 150 MB. The amount of space depends on the clients
that you install as features.
The following space is required for the Update Installer:
- 200 MB for the C:\Program Files\IBM\WebSphere\UpdateInstaller directory
-
The following space is
required for the Application Server Toolkit:
- 550 MB maximum for the C:\Program Files\IBM\WebSphere\AST directory
The Application
Server Toolkit does not include an integrated test environment.
Install the WebSphere Application Server Network Deployment product
and configure an application server to create a test environment.
- 550 MB maximum for the C:\Program Files\IBM\WebSphere\AST directory
The Application
Server Toolkit does not include an integrated test environment.
The installation wizard for each component
displays required space on the confirmation panel before you install the product
files and selected features. The installation wizard also warns you if you
do not have enough space to install the product.
If you
plan to migrate applications and the configuration from a previous version,
verify that the application objects have enough disc space. As a rough guideline,
plan for space equal to 110 percent of the size of the application objects:
- For Version 4.0.x: The size of enterprise archive (EAR) files
- For Version 5.0.x: The size of EAR files
- 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
disc is functioning correctly.
If you created your own product
disc from an ISO image or by copying the actual disc, 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 \win\WAS\jdk\java\bin directory
on the product disc. Type the following command:
cd disc_drive_D:\WAS\jdk\java\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.
