Abstract: The invention relates to a process for simulating, in a network, a server architecture from a client architecture in a first machine (PS) for the execution of remote procedure calls (RPC sent by at least one machine with client architecture (CL). In this this process, the first machine (PS) initially sends an RPC call to a third machine with server architecture (RE) which is used as a relay machine between the first (PS) and the second (CL) machines, and this RPC call opens a communication context for the sequence of exchanges while the first machine (PS) blocks itself on standby for a return of the RPC call. When the second machine (CL) sends an RPC call which represents a predetermined function to be executed by the first machine (PS), this call is transmitted to the relay machine (RE) which, after recognizing the function, retransmits it to the first machine (PS) through a return of the blocked RPC call.

Abstract: A tool for generating and executing graphical interface commands (OGEC) for an information system (SI) including heterogeneous platforms (PLC1-PLC4) disposed in a multi-protocol (PR1 through PR6) network (RE), comprising a descriptor file (FD) which describes the graphical interface to be produced in a specific grammar, means (AL) for verifying the grammar, means (MRG) for generating a graphical representation, connected to the verification means and to the graphical interface tools, means (AS) for checking the syntax of the data entered by the user into the graphical representation, multi-protocol means (ENC) for encapsulating the attributes of each command to be executed in the target platform(s) (PLC1 through PLC4), and means for receiving the attributes of each command and for executing it (EXEC1 through EXEC4) in accordance with these attributes.

Abstract: An application integration architecture (MO) for a data processing platform (PL) constituted by a network (RE) of machines running a plurality of heterogeneous applications (APA), the codes of which are not modifiable and each of which includes a plurality of external interfaces (IE), characterized in that, for the purpose of modifying the basic characteristics of these applications in a way that is transparent to the user, it comprises:a) an ergonomic integration module (MIG) for the centralized control of the applications with a graphical interface (GI),b) an operational continuity module (MCF) which executes actions to prevent them from operating abnormally,c) a module (MSC) for intercepting the dialogues between the components in order to ensure their logical security and the accounting of the resources consumed by the user.
