As illustrated in Figure 3, a noninteractive installation can be used for either an Express or a Custom installation.
IMPORTANT: A noninteractive installation requires that you install the gettext.rpm on the server or the installation will fail. See System Software Requirements.
The NNLS installation can run automatically (noninteractively) if you prepare a response file with the required information prior to running the installation script. When properly configured, a response file provides all the configuration input the installation script needs to install a product. We provide both Custom and Express template files that you can customize and then use as response files for performing noninteractive installations.
If you have multiple servers with similar configurations, you can quickly create a response file for each server by doing either of the following:
IMPORTANT: All parameters must be properly specified, including passwords. Otherwise, a noninteractive installation will fail and indicate the first incorrectly specified parameter. The install script assigns the password you supply, but it doesn't write the password to the configuration file that you can save at the end of the installation process.
Download the template response file for the installation type you want to run:
Open the file in a text editor that saves in standard UNIX* text format.
For help identifying the information needed, refer to the NNLS Planning Worksheet.
For help completing the installation, refer to the instructions at the start of the file.
IMPORTANT: In contrast to Interactive installations that let you save the .conf file at the end of the process, noninteractive installations do not save (overwrite) the .conf file.
This means that the .conf file remains on the system after the installation concludes, and the passwords you specified in the .conf file are available to anyone who can read it.
Therefore, you might want to manually delete the .conf file after performing a noninteractive installation.
