LBI-39169 USING OPENVIEW NETWORK NODE MANAGER

13.11 MULTIPLE EDACS NETWORK MANAGER SESSIONS
OpenView Network Node Manager supports multiple login sessions. Multiple sessions can be accomplished by using an
X-Station or by using a PC running PC Xware.
Certain restrictions apply in situations where multiple users are logged in using OpenView Network Node Manager. The
main restriction is that only one user gets full map read-write access. All other simultaneous users of OpenView NNM get
read-only map access. See LBI-39171, EDACS Network Management Installation and Technical Reference Manual, for
information on restricting write access to OpenView.
The read version of OpenView will see icon status updates and be able to perform the following operations:
•
Event Configuration
•
IPMAP polling
•
Application Builder
•
MIB Browser
•
MIB loading/unloading.
The main ramification of this restriction is that a read-only map cannot be edited. The effect of this is that during a read-
only OpenView Network Node Manager session, any changes in map topology are not reflected; i.e., any newly discovered IP
Network Elements are not shown to the read-only user. However, this also means that the user may not move icon positions
on maps or delete/add icons. The customer may therefore designate the write privilege for an administrator and the read-only
privilege for general users.
The read-only user continues to see Network Element status changes through icon color changes. Also, a read-only user
can still run management applications to monitor performance and change configuration on Network Elements.
Remote login is supported via an X-session from the remote device to the EDACS Network Manager. This is available
over a LAN or via a terminal server with modem (using SLIP or PPP). Due to memory constraints, the maximum number of
remote sessions available at one time is dependent on the EDACS Network Manager option chosen. Refer to the Remote
Access section in the Installation manual, LBI-39171.
13.12 INTEGRATION WITH OTHER NETWORK MANAGER APPLICATIONS
OpenView Network Node Manager provides the mechanism for allowing multiple applications to be registered with it via
Application Registration Files (ARFs). In order for the EDACS Network Manager to be interoperable with other OpenView
Network Node Manager-based applications, all applications must be registered with OpenView Network Node Manager. The
ARF provides information to OpenView Network Node Manager on how to integrate the application into the menu structure,
how to invoke the application, and how to manage the application.
The EDACS menu co-exists with all other menus, including those added by another EDACS NM application. The user
of the EDACS Network Manager can manually place icons from another application into EDACS NM maps or vice versa.
