Installing Informix Warehouse Accelerator

You can use the graphical mode, console mode, or silent mode to install Informix® Warehouse Accelerator.

Before you begin, see the Informix Warehouse Accelerator prerequisites and requirements.

You can install Informix Warehouse Accelerator on the same computer as your Informix database server, on a separate computer, or on a cluster system.

You can install Informix Warehouse Accelerator from the provided installation media, or you can install it after you download Informix from IBM® Passport Advantage®.

On the computer where you want to run the Informix Warehouse Accelerator installation program, log in as user root.
From the product media or the download site, locate the HCL Informix bundle and unpack the iif.version.tar file.
Select the installation mode that you want to use:
- For the graphical or console mode:
  1. Issue the install command to start the installation program:
    Installation mode Installation command
    
    Graphical ./iwa_install -i gui
    
    Console ./iwa_install -i console
  2. Read the license agreement and accept the terms.
  3. Respond to the prompts in the installation program as the program guides you through the installation.
- For the silent mode:
  1. Make a copy of the response file template that is located in the same directory as the Informix Warehouse Accelerator installation program. The name of the template is iwa.properties.
  2. In the response file change the value for license from FALSE to TRUE, to indicate that you accept the license terms. For example:
```
DLICENSE_ACCEPTED=TRUE
```
  3. Issue the installation command for the silent mode. The command for the silent mode installation is:
```
./iwa_install -i silent -f "file_path"
```
    Tip: Specify the absolute path for the response file.
    For example, to use the silent mode with a response file called installer.properties that is located in the /usr3/iwa/ directory, the command is:
```
./iwa_install -i silent -f "/usr3/iwa/installer.properties"
```
