All sensitive information, such as passwords, is now read from files. This information is not typed in clear text during an interactive session. Therefore, it is never displayed in the command line or in any logs. For more information about the use of a password file, see the related pre-installation step in the following section,Preparing to Install Agent for BEA WebLogic Server 9.0/9.1 for information about creating and using a password file during the agent installation process.
Benefit - Secure Handling of Sensitive Information: The benefit of this feature is increased security. With the use of this feature in the new installation process, the need for typing passwords in clear text on the command line has been eliminated, thereby making the installation process less vulnerable to password theft.
