To install Oracle Solaris, two general methods are available:
Using the text installer
Using Automated Installer (AI)
In turn, each method has options for further customizing how your chosen installation method would run in your specific environment.
Based on these available methods, the documentation for Oracle Solaris installation is organized as follows:
To use the text installer, refer to Manually Installing an Oracle Solaris 11.4 System. It describes procedures for installing Oracle Solaris manually.
To use the automated installer (AI), refer to Automatically Installing Oracle Solaris 11.4 Systems, which is the current guide. It describes procedures to set up the necessary components for a "hands-free" Oracle Solaris installation.
To perform a customized automated installation, refer to Customizing Automated Installations With Manifests and Profiles. This guide discusses in further detail how to use AI manifests and system configuration files to customize an automated installation. It is an important companion guide especially to Automatically Installing Oracle Solaris 11.4 Systems.
