To allow the silent installation of Identity Governance to work, Identity Governance reads passwords stored in environment variables or entered into silent properties files. For more information, see Understanding the Passwords that Identity Governance Reads from Environment Variables During the Installation Process.
Specify each password either as an environment variable, or in the silent properties file before you run the silent installer.
If you are performing a silent installation for the Identity Governance components, ensure that you use the current silent properties file for the proper component, and then update these properties with the values in your old silent properties files.
If you specified passwords as environment variables for the silent installation, you can remove these variables after the installation completes by following the appropriate procedure for your operating system.
