protection of a volume
The VOLPRO privilege permits control only over
volumes that the user's process can mount or initialize. Volumes
mounted with the /SYSTEM qualifier are safe from a process with the
VOLPRO privilege as long as the process does not also have the SYSNAM
privilege.
Exercise extreme caution when granting the VOLPRO
privilege. If unqualified users can override volume protection, the
operating system and service to others can be disrupted. Such disruptions
can include destruction of the database and exposure of confidential
information.
The VOLPRO privilege lets a process perform the
following tasks:
