Decide between Interactive and Noninteractive Installation

By default, the installation script prompts you for each configuration item. However, you can also point the script to a response file and let the installation processes run automatically.

Figure 3 illustrates the contrast between an interactive and a noninteractive installation.

Interactive vs. Noninteractive Installation

To install NNLS interactively, follow the instructions in Performing an Interactive Express or Custom Installation.

To install NNLS automatically (noninteractively), you must first prepare either an Express or a Custom response file. For more information, see Performing an Interactive Express or Custom Installation.

Table 1 might help you decide which installation method best fits your situation.

The installer (usually a system administrator) must access the server and answer each installation question as it is presented.

A system administrator can prepare a response file before the installation is run. Someone else can then run the installation script.

Each installation requires roughly the same time investment.

Multiple response files can be prepared using the first file as a template. This is especially useful if you have a number of NNLS installations that share similar configurations.

The disadvantage to the interactive, manual process is that it takes more of an individual's time, but it provides a better understanding of what is happening during the installation process.

This automated option requires fewer man-hours and is easily repeatable.
