HP OpenView Data: Objects and Fields
The OpenView database is used by applications to store a wide range of
information about network objects. An object is an internal
representation of a logical or physical entity or resource that exists
somewhere in a computer network. It consists of a unique object
identifier and a set of fields that specify all the characteristics of the
object.
VPO automatically makes topology information available in the
OpenView database; it also adds new fields such as “IP Status”. This
information is then available to management applications. VPO uses
OpenView database information to generate network maps and
hierarchies.
Other applications are able to read, write, and create OpenView
database objects and fields. New fields can include information such as
node serial numbers, trouble reports, or non-IP status. Access to this
database is provided through the HP OpenView programmer’s interface.
The HP OpenView programmer’s interface provides almost 50 functions
for interaction with the OpenView Windows object database. The API is
not as complex as it might first appear, though. Among other things, it
provides access to perform the following tasks:
❏ Field operations
• Creating Fields
Fields can be created either using the appropriate API routine or
the Field Registration File (FRF). The FRF is the normal and
preferred way to create fields.
• Getting Field information for a single or all fields
• Getting/Setting object field values
❏ Object operations
• Creating an object
• Deleting an object
❏ Convenience Routines
