Computer system having an authentication and/or authorization routing service and a CORBA-compliant interceptor for monitoring the same

摘要

A CORBA-compliant computer network includes a registration server on which an AAR service resides, a registry database and an ORB which couples the registry server to the registry database. A CORBA-compliant interceptor residing on the ORB intercepts each message, generated by the AAR service, invoking the registry database and each message, generated by the registry database, responding to the invocation message generated by the service of the client server. The interceptor selects information useful in determining the cause of a failed usage of the service residing in the client server from each intercepted invocation and response messages, writes the selected information to a data store residing in the client server and then re-invokes the intercepted invocation and response messages. In the event of a network failure, the data written to the data store may be reviewed to obtain useful information regarding the network failure.
