22 DSView Installer/User Guide
The default preemption levels for built-in user groups within the DSView software are listed in
Table 1.8.
A user-defined user group may be assigned a preemption level of 1-4.
• Effective user preemption level - The largest value between the user and group preemption
level. This is the actual preemption level that will be recognized by the DSView software when
the DSView user attempts to preempt another DSView user’s DSView session. For example, if
a DSView user belongs to the Auditors group (level 1) but is assigned a user preemption level
of 4, the DSView user will have an effective user preemption level of 4. Even though the
DSView user is a member of the Auditors group, they would be able to preempt the DSView
session of a DSView user belonging to the DSView Administrators or Appliance Administra-
tors user groups.
A DSView Administrator or User Administrator may also specify an OSCAR preemption level that
is applied to DSView users accessing target devices through OSCAR. See Modifying DSR switch
or CPS appliance port settings on page 174 for more information.
Using Certificates with the DSView Software
The DSView system uses certificates to provide secure transactions between components and to
uniquely identify components in the DSView system.
DSView Server certificate
A DSView Server certificate is used to do the following:
• Uniquely identify the DSView Server to DSView Clients connecting to the server using
web browsers.
• Uniquely identify the DSView Server to other DSView Servers in a DSView System
• Provide for secure transactions between DSView Clients and the DSView Server.
• Provide for secure transactions between DSView Servers.
