Installing WAS V5.1
This topic describes how to install WebSphere Application Server products as the root user on a Linux platform or on a UNIX-based platform, or from a user ID that belongs to the administrator group on a Windows platform.
Log in as user root
You cannot install WAS correctly as a non-root user on a Linux or UNIX-based operating system platform, or from a user ID on a Windows platform that is not part of the administrators group. If you back up the product CD-ROM on a Linux or UNIX platform, do so as root. Backup copies made from non-root users do not preserve the correct file attributes and do not work.
In addition, Linux and UNIX installers must verify that the umask setting is 022. To verify the umask setting, issue the following command:
umask
To set the umask setting to 022, issue the following command:
umask 022
Linux platforms and Solaris operating environments
On Linux platforms or Solaris operating environments, make sure that the /etc directory contains a shadow password file. The shadow password file is named shadow and is in the /etc directory. If the shadow password file does not exist, an error occurs after enabling global security and configuring the user registry as local operating system.
To create the shadow file, run the pwconv command (with no parameters). This command creates an /etc/shadow file from the /etc/passwd file. After creating the shadow file, you can configure local operating system security.
Some steps of the installation procedure on a Windows platform require the user to belong to the administrator group and have the following advanced user rights, Act as part of the operating system and Log on as a service.
WebSphere Business Integration Server Foundation is the V5.1
level of the Enterprise product. WebSphere Business Integration Server Foundation, V5.1 extends Network Deployment
V5.1. After migrating the underlying product to V5.1, do not reinstall the
V5.0.x Enterprise product. V5.0.x of the Enterprise product does not
extend V5.1 of the WAS ND
product.
Read through this topic and its related topics to prepare for installation and to make yourself familiar with installation options, before you start to use the installation tools.
Review the prerequisite requirements on the IBM WAS supported hardware, software, and APIs Web site to get started.
After verifying prerequisites, read these topics before installing WAS:
- Platform-specific tips for installing and migrating
- Tips for installing the embedded messaging feature
- Migrating and coexisting
- Using the Launchpad to start the installation
- Installing silently
If you encounter a problem such as not having enough disk space or temporary space or not having prerequisite packages on your Linux or UNIX-based system, cancel the installation, make the required changes, and restart the installation to pick up the changes that you made.
The installation uses InstallShield for Multiplatforms (ISMP) to perform the installation. You can use the Installation wizard or perform the installation from a command line, using the silent installation method.
The Installation wizard does not support hot keys, such as Alt-Y. You can tab to the Yes key and press Enter to select it, for example.
Although you can create multiple servers on a base WAS node, the servers all share one set of configuration files. Changes that you make to one server affect the others. There is a possibility that configuration documents might become corrupted. Use configuration instances to create multiple servers, each with its own set of configuration files. Or install the ND product to create and manage multiple base Application Servers.
Install the
base product before installing the ND product when installing
both products on the same machine. The embedded messaging feature that is
included in the default installation requires this specific order of installation.

Open this topic in the information center
for the WebSphere Business Integration Server Foundation product to learn how to install the Integration Server installation
image and extend the multimachine environment. The CD-ROM for the Integration Server installation
image is labeled, Integration Server.
This topic describes installing the ND product, using the installation image on WAS CD-ROM labeled, Deployment Manager. Use a CD-ROM labeled, Application Server, IBM HTTP Server, in the ND product package to install the base WAS product. Open this topic in the information center for the base WAS product to learn how to install the base WAS product.
The Deployment
Manager CD-ROM is available in both the ND product package
and the WebSphere Business Integration Server Foundation product package. Use this information center topic to install
the ND product, regardless of which package the CD-ROM comes
from. Open this topic in the information center for the Integration Server product
to learn how to install the Integration Server product and extend the multimachine
environment. The CD-ROM for the Integration Server product is labeled, Integration Server.
This topic is available in Adobe PDF format, on WAS CD-ROMs, and online in an information center that is available from the IBM WebSphere Application Server Web site at http://publib.boulder.ibm.com/infocenter/ws51help/index.jsp . When possible, access the most current version of this information by selecting the information center. The information center displays in the language of your machine locale.
OverviewThe Launchpad tool lets you access WAS overview, the readme.html file, and installation guides. You also use the Launchpad during the installation procedure to install WAS. See Using the Launchpad to start the installation for more information.
The Installation wizard performs the following actions:
- Automatically checks prerequisites
- Looks for a previous WAS installation, to determine whether to display the Migration panel or the Coexistence panel during the installation
Steps for this task
- Install WAS ND
on your platform.Use one of the following procedures:
- Install ND on AIX platforms, as described in Installing ND on AIX platforms.
- Install ND on HP-UX platforms, as described in Installing ND on HP-UX platforms.
- Install ND on Linux platforms, as described in Installing ND on Linux platforms.
- Install ND on Solaris platforms, as described in Installing ND on Solaris platforms.
- Install ND on Windows platforms, as described in Installing ND on Windows platforms.
- Install ND on AIX platforms, as described in Installing ND on AIX platforms.
Results
The Installation wizard configures WAS. It is not necessary to perform further configuration at this time.
You have now successfully installed WAS ND and the features that you selected.
