Definitions
- the invention relates to a method for operating a data processing system according to the preamble of claim 1 and an arrangement for performing this method.
- CORBA Common Object Request Broker Architecture
- C0M + trade name of a product from Microsoft
- RMI Remote Method Invocation, a Java implementation from Sun Microsystems
- Applications that do not use object-oriented approaches in the manner of RPC Remote Procedure Call, method from Sun Microsystems
- application also includes a combination of logically separated individual applications that communicate with one another via the mechanisms mentioned.
- a user calls methods of a remote server object (also referred to as "remote object") to execute an application.
- a valid reference to the server object must first be found. This process is referred to below as "binding".
- a client can theoretically bind any number of server objects as often as required and call the methods of a server object as often as required.
- a server object can theoretically be bound or referenced by any number of clients.
- FIG. 1 A known system of this type is outlined in FIG. 1, where the connections of four clients, client 1 to client 4, to four different server objects implemented on two servers A and B are shown as an example.
- This process is outlined in FIG. 2 for a client, a proxy object, a job and a server object - referred to here as the "original object”.
- this is intended to provide a performance-related and thus significantly more transparent billing of the use of software compared to the previous time and user number-related billing. Furthermore, an arrangement suitable for carrying out the method is to be specified.
- the invention includes the basic idea of a dynamic, request-oriented organization of distributed applications in units of the individual method calls " . It further includes the idea of using a suitable system structure to generate so-called” jobs "from the method calls that the existing server objects in It also includes the idea of transferring the processing of the individual jobs to the server object (which is suitably trained, ie "technically responsible") who first responds to the job offer.
- the jobs are managed individually - both in terms of the user (client) and in terms of load balancing.
- the jobs correspond to messages that are transmitted between clients and server objects.
- Each method call initiated by a client generates a job request (after conversion into a job and transmission as a message).
- the return values of method calls are transported back to the calling client as response jobs.
- a user interface can correspond to a client, but it can itself be the server object of another client in a method call chain.
