TECHNICAL FIELD
The field of the present invention relates to common management information protocol (CMIP) agent registration methods, systems and computer program products, and more particularly to methods, systems and computer program products for autoregistration of CMIP agents with UNIX processes acting as a gateway between a management information server (MIS) running on a host and external entities which communicate with the local host MIS.
BACKGROUND OF THE INVENTION
Common management information protocol (CMIP) management protocol adapter (MPA) is a UNIX process which serves as a gateway between a local MIS running on a local host and an external or remote entity or agent, such as another MIS or a third party manager. The remote entity or agent communicates with the local MIS using CMIP protocols.

and a remote MIS

in communication with each other. The local host

has installed thereupon a local MIS

5
which is connected between the local MIS
3
′ and the remote MIS
4
for bilateral communication. Remote MIS

is a third party manager or an agent or another kind of a communicating entity. CMIP MPA

acts as a UNIX process gateway using CMIP protocol to effect communication between a local MIS
3
′ and a remote MIS
4
. For communication according to the prior art, the local MIS is preconfigured according to at least a single predetermined agent information model. As shown in the block diagram of
FIG. 1B
, the prior art local MIS
3
′ includes an information model
13
which is preconfigured with a configuration model for each predetermined communicating remote entity
14
, but not for unanticipated agents. If an agent or remote MIS which does not conform to the predetermined agent information model prepared in anticipation of agent communication by the local MIS, then run-time communications between hosts and particular remote entities are prevented. It is desirable to overcome this technological inadequacy of the prior art, which prevents unanticipated remote agents not falling within the preconfiguration model of the local MIS from engaging in local MIS communications.
It is additionally desirable to avoid technical problems arising when a remote agent or another remote communication entity, such as a remote MIS, or third party manager, is not recognized by the local MIS. Such a failure to recognize the remote entity prevents communication from being established.
It is further desirable to make unpreconfigurable remote agent communication possible with local MIS entities, as well as user transparent and convenient for rapid implementation.
SUMMARY OF THE INVENTION
According to one embodiment of the present invention, a computer network includes an object-oriented local MIS which is run-time configurable for communication with remote agents of unknown architectural configuration, and a common management information protocol (CMIP) MPA enabling communication between the local MIS and remote agents characterized by an unknown information model, by translation of management object instances and agent object instances. The computer network, according to the present invention, can implement installation of a computer program product according to one embodiment of the present invention and is able to identify remote agent communication events representing remote agent association requests received by the CMIP MPA. The CMIP MPA runs a code mechanism for translating messages transmitted between a remote agent and said local MIS. More particularly, according to the present invention, unregistered remote agents are represented in a local MIS for communication through a common management information protocol (CMIP) MPA, by identifying remote agent communication events representing a remote agent association request received by a CMIP MPA. Messages transmitted between a remote agent and a local MIS are translated by the CMIP MPA. According to one embodiment of the present invention, a remote agent is represented in the local MIS as an object identifying a communication configured remote agent entity.
