How NNM Works Processes associated with a user’s interactive ovw session. Foreground Processes, started by ovstart, which monitor network nodes. Background Processes (Services) Network OpenView Database Contains data stored and used by foreground and background NNM processes. OpenView and NNM Fundamentals

The OpenView Databases • Object database. Contains general object information, including some object attributes and capabilities. • Topology database. Contains specific topology information maintained and used by the IP network discovery and layout services. • Map database. Contains map-specific information, such as submap customizations and symbol placement. OpenView and NNM Fundamentals

Accessing Object Descriptions OpenView and NNM Fundamentals
Capabilities and General Attributes • Describe the object. • Set by NNM during discovery. • Capabilities cannot be changed. • General attributes are rarely changed. OpenView and NNM Fundamentals
IP Map Object Attributes • IP-specific attributes • Set and maintained by IP Map • Vary with the object type OpenView and NNM Fundamentals
Locating an Object • An object (corresponding symbols) may be located in the map via one of the following search methods: • By Selection Name • By Attribute • By Comment • By Symbol Status • By Symbol Type • By Symbol Label OpenView and NNM Fundamentals
Symbol Class and Subclass • Symbol class • Groups related symbols • Defines a symbol’s geometric shape • Symbol subclass • Corresponds to a symbol icon • Image displayed on a submap • Superimposed on class shape OpenView and NNM Fundamentals
