This topic describes how to prepare your Windows systems for the installation of IBM WebSphere Application Server, Version 6 products.
Before you begin
The installation uses a InstallShield for Multiplatforms (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.
Why and when to perform this task
Use the following procedure to prepare the operating system for the installation of WebSphere Application Server products.
Steps for this task
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.
The installation root directory includes the core product files. This size includes the Sample applications. This size includes space for the default Application Server profile for the server1 process. The requirement does not include space for applications that you might install.
Each Application Server profile requires approximately 200 MB plus 40 MB of temp space, and space for any applications that you develop and deploy.
The temporary directory is the working directory for the installation program.
This amount is the total space requirement when installing the product from the CD.
The following space is required for the IBM HTTP Server product:
The following space is the maximum amount that is required for the Web server plug-ins for WebSphere Application Server:
The following space is required for the Rational Web Developer:
The amount of space that is required to install the Rational Web Developer is actually less than 2.5 GB, depending on the optional features you select during installation.
The amount of space that is required depends on the features that you install. For example, without the language pack feature for support of national languages, the space required is approximately 1.7 GB. Included in the 1.7 GB is approximately 550 MB of disk space for the integrated test environment for Version 6. An integrated test environment for Version 5 is on disc 4.
The integrated test environment lets you install Rational Web Developer without installing the Express product on your development machine. The test environment is an exact replica of the product code that is sufficient for developing and testing applications.
After installation, additional disk space is required for developer work space. The size required by the work space depends on the size of the applications under development.
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.
Although the Installation wizard checks for prerequisite operating system patches with the prereqChecker application, review the prerequisites on the IBM WebSphere Application Server supported hardware, software, and APIs Web site if you have not already done so.
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 from the following Microsoft Web page: http://www.microsoft.com/ downloads/ details.aspx? FamilyId= C717D943-7E4B-4622-86EB-95A22B832CAA.
If you created your own product CD from an ISO image or by copying the actual CD, perform the following steps to verify that the Java 2 SDK on the product CD-ROM is working correctly.
cd CD_Drive_D:\WAS\jdk\java\bin
.\java -version
The command completes successfully with no errors when the Java 2 SDK is intact.
Result
This procedure results in preparing the operating system for installing the product.
What to do next
After preparing the operating system for installation, you can install the WebSphere Application Server product.
Go to Preparing to install the Express product on a Windows system for the next step in the overall procedure, which is selecting the type of installation to perform.
