Mutual authentication between a client and server over the Internet utilizing the IOP protocol in its current state is enabled by first engaging in a “dummy” request when a client initiates a request to a new target server for the first time. This provides the means for creating a two way authentication mechanism. Rather than creating an object reference for the dummy request, the object reference at hand in the client, which the client is about to utilize for a request, is reused by extracting a proxy object from the request. The request is intercepted in the client and the proxy object passed to the interception method. The client next issues a two-way remote method already defined for the proxy object, such as the “non_existent( )” method defined on the CORBA object. The client then computes a security token, and sends the dummy request to the server. The server intercepts the dummy request, validates the security token received in the dummy request, and acquires a new authentication token to be returned to the client. Upon interception of the outgoing message, the new security token is marshalled in the security service context and sent to the client on the response message. The client intercepts the reply message and demarshals the security service context to recover the security token and complete mutual authentication.

A method and implementing computer system are provided in which a unique primary key is generated to identify an original message which is received for processing. The record for the original message is stored at the primary key. As the message is propagated to the services that are to be performed on the original message, the primary key is also passed to the service. Derivative messages which are produced as a result of the services applied to the original message are identified with the primary key code along with additional derivative key codes related to services applied to the original message. The resulting derivative message storing and tracking process provides a means by which derivative messages are readily identified and associated with an original message as well as the services performed upon the original message in generating the derivative message.

A method for metering on-demand service (ODS) resource consumption by a user comprising a web services interface, a processing engine, and configuration data. A data gathering agent in the ODS stores the usage data in records, combines the records into packets, and transmits the packets to the web services interface. The web services interface passes the packets onto the processing engine, which stores the records in the packet into a database. The generalized format of the record is critical because it allows the metrics to be stored in the record table with the usage data. When a record contains an instruction to close a UOW, the processing engine applies the configuration data comprising composition rules and record selection rules to the database. The record selection rules select the desired records from the database. The composition rules aggregate, normalize, and compose the selected records to produce a metric.
