Adding product modules to an installation

You can add product modules to an existing IBM® InfoSphere® Information Server installation by rerunning the same installation program that was used for the installation of the most current version.

Before you begin

Ensure that you use the same version of the installation program to install additional tiers or product modules. For example, if you install version 11.5, and then 11.5.1 is released, do not try to install additional tiers or product modules with the 11.5.1 image. If you want to install a later version of the tiers or product modules, then migrate your existing version. You can, however, add tiers or product modules to a version of the product that has had fixes and service packs applied. However, in that case you might need to reapply the updates afterward.
- Choose your installation topology, review the installation checklists, and prepare the tier computers.
- Obtain the product media to include the installation and entitlement packages.
- Configure your browser correctly so that the installation program runs smoothly.
- Microsoft Windows: Start an administrator session by using one of the following methods:
  - Run the following command:
```
runas /user:Administrator cmd.exe
```
  - Open an elevated command window.
    1. Click Start > Search.
    2. In the Search Results box, enter cmd and press Ctrl+Shift+Enter.
    3. Click Continue to accept the prompt asking for your permission to continue.
- AIX Linux: Log in as the root user.
Ensure that you have a current backup of your InfoSphere Information Server installation.
Do not use the InfoSphere Information Server installation program to add IBM InfoSphere DataStage® editions or feature packs after initial installation. Instead, enable them by using the iisAdmin tool. Refer to Activating entitled IBM InfoSphere DataStage editions and feature packs.
If the WebSphere® Application Server processes or node agents are currently running under a non-root user, there is no longer a need to change them to run as root before running the installation or uninstallation program. However, after running the program, the application server will have been switched to run as root. Therefore, if you want to run it as non-root again, you will need to switch it to run as the non-root user afterward.

About this task

Depending on the product modules that you select, you might not have to run the installation program for all tiers. Not all product modules have components on all tiers. You only need to run the installation program on the tier computers that contain components for the product modules. You can skip tier computers that do not contain components for the product modules.

The following table lists product modules and indicates the tier computers on which you must run the installation program.

Table 1. Product modules and the tiers on which you must run the installation program
Product module	Services tier	Engine tier	Repository tier	Client tier
IBM InfoSphere FastTrack	X			X
IBM InfoSphere Information Analyzer	X	X	X	X
IBM InfoSphere Information Governance Catalog	X	X		X
IBM Glossary Anywhere (requires Information Governance Catalog). The client is installed separately.	X
Metadata interchange agent and bridges (installs IBM InfoSphere Metadata Integration Bridges for use with InfoSphere Metadata Asset Manager.				X
All others	X	X		X

The installation program only installs the appropriate software for the tiers on a computer. You can run the installation program on all of the computers in your configuration, and select the products to be installed each time. The installation program determines automatically which tiers exist on each computer and adds the appropriate components.

Run the program on the computers in the following order:

Repository tier, if the product modules you are installing require changes to this tier.

If you preinstalled the database system for the metadata repository and configured the databases within the database system by using the scripts that are supplied with the installation media, you do not run the installation program on the repository tier computers.
Services tier. All product module additions require changes to the services tier.
Engine tier, if needed. Refer to the table to determine whether you need to run the installation program on the engine tier.

If the product modules you are installing require an engine tier installation, and the engine tier is not present, first install the engine tier as described in the procedure.

Note: If the metadata repository contains host computer assets with names that are not specified in all upper case (that is, lower case or mixed case), then contact IBM Support before running the installation program to install additional products on the engine tier. You can determine the case of the host computer assets (data resources) by logging into InfoSphere Metadata Asset Manager and navigating to Repository Management > Browse Assets > Implemented Data Resources.
Client, if the product modules you are installing require changes to this tier.

The client tier installation can take place at any point in the sequence.

For example, to install IBM InfoSphere Information Analyzer, first run the installation program on the repository tier computer. Then run it on the services tier computer. Lastly, run the program on the engine tier. You can run the installation program on the client tier computers at any point in the sequence.

InfoSphere DataStage and IBM InfoSphere QualityStage® share many components. For this reason, if you add one of these product modules to a system on which the other product module is installed, the installation process runs faster.

IBM InfoSphere Information Analyzer shares many of the same components as InfoSphere DataStage and InfoSphere QualityStage. The installation process for IBM InfoSphere Information Analyzer runs faster if InfoSphere DataStage or InfoSphere QualityStage is already installed.

Procedure

Verify that the appropriate software tiers are present in your installation to install the product module. If a required tier is not present, install and configure the tier as described in the Adding additional tiers to an installation topic.
For example, if you installed only IBM InfoSphere FastTrack, your installation does not have an engine tier. To add InfoSphere DataStage, first create an engine tier.
Run the installation program on the computers.
- Follow the prompts. When the installation program detects the existing installation and prompts you to choose whether to add additional products or tiers, select Add products.
- Continue to follow the prompts to select the products to install and to complete the installation. The product modules that are displayed are only those that are part of the entitlement package that you purchased.
Repeat the process for each target computer.
Run the IBM Support Assistant Lite for InfoSphere Information Server tool to verify the installation.

What to do next

Configure the newly installed product modules.

If you disabled scheduled tasks or deployed applications before running the installation program, restart the tasks and reenable the applications.
