Installing

You can use the graphical mode, console mode, or silent mode to install .

Before you begin

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

You can install from the provided installation media, or you can install it after you download Informix®.

On the computer where you want to run the 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 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"
```

Installation mode	Installation command
Graphical	`./iwa_install -i gui`
Console	`./iwa_install -i console`

is installed in the directory that is specified by the INFORMIXDIR environment variable, if the INFORMIXDIR environment variable is set in the environment in which the installer is launched. Otherwise, the default installation directory is /opt/IBM/informix.
The configuration file, $IWA_INSTALL_DIR/dwa/etc/dwainst.conf, is generated during the installation. This configuration file is required to start .
The installation log file, $IWA_INSTALL_DIR/IBM_Informix_Warehouse_Accelerator_InstallLog.log, is generated during the installation. This log file provides information on the actions performed during installation and success or failure status of those actions.

You must configure and start before you can use it.
