You can install additional features on an existing IBM WebSphere
Application Server - Express for i5/OS installation. You can install from
the installation image on the product disc, or the downloaded Passport Advantage
image.
Before you begin
This topic assumes that you have an existing Express for i5/OS installation
and that you want to install a feature using the installation wizard from
a Windows workstation graphical user interface (GUI).
One feature is available,
which installs sample applications.
About this task
When you run the GUI installation tool, you specify installation
options interactively during the installation process.
Use the following
procedure to add a feature to an existing Express for i5/OS installation.
Procedure
- If TCP/IP is not started or if you don't know if TCP/IP is started,
enter the Start TCP/IP (STRTCP) command on the Control
Language (CL) command line.
- Verify that the host server jobs are started on your iSeries server.
The host server jobs allow the installation code to run on iSeries.
Enter this command on a CL command line:
STRHOSTSVR SERVER(*ALL)
- Verify that your user profile has the *ALLOBJ and *SECADM special
authorities.
- Stop each running application server
with the stopServer command.
Stop
all server processes in all profiles on the machine. For example,
issue the following command from the
profile_root/bin directory
to stop the server1 process in the application server profile:
./stopServer.sh server1
If
a server is running and security is enabled, use the following command:
./stopServer.sh server1 -user user_ID -password password
- Uninstall all maintenance packages.
You are using the product installation image to install additional
features. The features have not had any maintenance applied to them.
If you remove all maintenance packages, your entire product will be
at the same release level. You can then reapply the maintenance packages
as described in a later step.
Start the Update Installer program with the updi_root/update command
to search for and uninstall all maintenance packages.
- Place the Express for i5/OS disc that provides the feature in the
disc drive of your Windows workstation. The autorun feature brings up the
launchpad.

Do not use the product Windows disc or any other operating system
disc from the product package.
- On the Welcome panel, click Next.
- On the next panel, if you accept the terms of the license agreement,
select I accept the terms in the license agreement,
then click Next. If you do not accept the terms of
the license agreement, you cannot continue with the installation.
- After confirming that your operating system is supported and that
you have installed all necessary patches, click Next to
continue.
The installation wizard checks for a previous installation
at the same product level. This task describes the scenario where a previous
installation exists and you are adding features with an incremental installation.
When
the wizard detects a previous installation, it displays the Existing installation
panel. The panel lets you add features to the existing installation, or perform
a new installation to another directory.
- Choose to install additional features. Click Next to
continue to the Features selection panel.
Do not change the
installation directory unless another existing installation is in another
directory. An incremental installation adds features to the shared binaries
identified in the location field.
You can add features to the binaries
at any time, by running the Installation wizard again. Installing additional
features does not affect profiles that you might have already created. (Profiles
are runtime environments that are described in a later step.)
When adding
features during an incremental installation, the wizard displays the Features
selection panel.
- Select features to install and click Next.
In Version 6.1, one feature is available, which
installs sample applications.

Application Server
Samples |
Installs the Samples Gallery and Plants
By WebSphere applications. |
For better performance in either a development or production environment,
do not install the Samples. By omitting the Samples, you can improve application
server startup time by 60 percent and save 15 percent of disk space. You can
save up to 30 percent of process footprint (based on a maximum heap size of
256 MB).
The installation wizard displays a confirmation panel.
- On the next panel, verify that the summary information is correct.
If not, click Back to change your specifications. If
the summary information is correct, click Next to install
the feature.
The InstallShield program displays messages that
indicate the status of the installation and a status bar to show the progress
of the installation.
After the installation runs, the Configuration
Manager progress panel is displayed. The configuration manager performs post-installation
tasks and creates the default profile.
After the installation process
is complete, the summary panel displays the results of the installation process
and links to additional information about the product.
- Select the check box to open the First Steps console, then click Finish to
close the InstallShield program.
- For security purposes, if the host servers were not running prior
to installation, it is recommended that you run the End Host Server (ENDHOSTSVR)
command after the installation is complete
Results
The installation wizard installs the new feature in the existing installation
root directory. The installation wizard configures the Express product for
the new feature.
What to do next
Create any application server profile that your configuration requires.
Adding
the samples feature does not automatically deploy the samples to existing
profiles that did not have samples deployed to them initially. You must create
a new profile to deploy the samples. For example, create an application server
profile and select to deploy the sample applications.
Use the Profile Management tool to
create profiles in the default profile_root directory
or in a directory that you select.
After creating an
application server profile, you can deploy an application. See Fast paths for WebSphere Application Server to
get started deploying applications.
