Individual Encryption Key for Secure Storage

You can set a randomly generated individual encryption key for the secure storage in the file system and the secure storage in the database.

DNS Domain Name for SAP System

The DNS Domain Name is used to calculate the Fully Qualified Domain Name which is configured in SAPLOCALHOSTFULL. It consists of the hostname and the domain name.
