This topic outlines various procedures used to install WebSphere Process Server.

Draft comment:
I replaced the version numbers following WAS
and WAS ND with "supported version."
WebSphere Process Server is
built upon WebSphere Application Server Network Deployment. As a result, there
are many different scenarios that can exist when you are installing the product.
You might install
WebSphere Process Server on
a clean system, or on top of an existing installation of a supported version
of WebSphere Application Server or WebSphere Application Server Network Deployment.
You might prefer to install the product with an interactive Installation Wizard
interface or silently, using a response file. You might want to let the Installation
Wizard create a default stand-alone server profile for you or bypass that
option and later use the Profile Wizard to create stand-alone, deployment
manager, and custom profiles. You might only want to install additional features
on an existing installation of
WebSphere Process Server or
want to install a completely new installation to coexist with an existing
one.

Because
there are so many different installation variations, we cannot document all
of them here. We have created some typical installation procedures, which
can be selected from the following list. Find the link to the installation
procedure you require and then use that procedure to install
WebSphere Process Server on
your system.

- Starting the Launchpad -- The
Launchpad is the single point of reference for installing the entire process
server environment, which can include WebSphere Process Server,
WebSphere Application Server or WebSphere Application Server Network Deployment,
a set of Web development tools, a Web server, and additional supporting software
and documentation.
- Installing additional features on an existing installation --
Select this installation method to install additional features on an existing
installation of WebSphere Process Server using
the Installation Wizard GUI. Ensure you have an existing installation of WebSphere Process Server on
your system. You do not have to have an existing WebSphere Process Server profile
to install additional features on an installation.
Installing the product for the first time using an existing installation of WebSphere Application Server or WebSphere Application Server Network Deployment Draft comment:
I
replaced the version number following WAS and WAS ND with "supported version.".
--
Select this installation method to install
WebSphere Process Server for
the first time using the Installation Wizard GUI, when you want to use an
existing installation of a supported version of WebSphere Application Server
or WebSphere Application Server Network Deployment. This procedure allows
you to run the Profile Wizard at the end of the installation to create a
WebSphere Process Server profile.
Ensure that you have WebSphere Application Server or WebSphere Application
Server Network Deployment already installed.

Installing the product silently Draft comment:
I
removed the version number following WAS ND.
-- Select the
silent installation method to install the product silently by using a command-line
invocation with a parameter that identifies an options response file, which
you edit before installing. You can use the silent method to install
WebSphere Process Server for
the first time using default or custom selections and configuration, or install
features on an existing installation. A silent installation can install
WebSphere Process Server,
WebSphere Application Server Network Deployment, and create a
WebSphere Process Server profile.

Draft comment: Add this note when NLS is supported:
Important: The
language of the Installation Wizard is determined by the default language
on the system. If the default language on the system is not one of the supported
languages, then a default language of English is used. You can override the
system’s default language by starting the Installation Wizard from the command
line and using the java user.language setting to replace the default language.
Use the following command, which can be run from the
WBI directory
on the
WebSphere Process Server CD
1:
On Linux and UNIX platforms: ../JDK/repository/prereq.jdk/java/bin/java
-Duser.language=locale -cp setup.jar run
On Windows platforms: ..\JDK\repository\prereq.jdk\java\bin\java
-Duser.language=locale -cp setup.jar run
For instance, to start the Installation Wizard in the German language
on a Windows system, type the following:
..\JDK\repository\prereq.jdk\java\bin\java
-Duser.language=de -cp setup.jar run
Remember: 
If you plan to install
WebSphere Process Server over an existing installation of WebSphere Application Server or WebSphere
Application Server Network Deployment for which you have enabled global security,
ensure you disable global security before installing
WebSphere Process Server.
For information on enabling and disabling global security, see the WebSphere
Application Server Network Deployment, version 6.0, information center at
http://publib.boulder.ibm.com/infocenter/wasinfo/v6r0/index.jsp.

Restriction: You cannot have two instances of the Installation
Wizard running concurrently. Attempts to run multiple instances of the Installation
Wizard concurrently result in a warning about installation already being in
progress.
The installer program does not support the ISMP-console installation method
at this time.
