Setting up the Oracle HTTP Server for Installation
During installation, the user account that owns the Oracle HTTP Server software
must be a member of the ORAINVENTORY group in order to complete installation.
The Oracle HTTP Server also must be started by the root user in order for ports
reserved for root to be made available to the database and applications. For
security reasons, Oracle Corporation recommends that provisions be made to
change the Oracle HTTP Server group membership to a low-privileged group, and
to transfer ownership of Oracle HTTP Server processes from root to a
low-privileged account.
