The invention especially relates to the execution of at least one transaction in a transaction processing system comprising a transaction-oriented monitor (), said at least one transaction being executable in an open-type execution environment, by the sequential execution of a plurality of transaction-oriented components (). According to the invention, and owner-type execution space is created () for enabling the execution of at least one transaction-oriented component from said plurality of transaction-oriented components, said at least one transaction-oriented component being developed for an owner-type execution environment separate from the open-type execution environment, during the reception () of a corresponding execution control from the transaction-oriented monitor.

Method and device enabling the execution of heterogeneous transaction components

The present invention concerns a device permitting the utilization of a remote procedure call of open systems employing the socket process in a proprietary application, utilizing primitives which do not exist in the proprietary system and running on a computer system which makes use of an open subsystem utilizing the socket, comprising: means for communicating between the proprietary application and an application of the open subsystem; means for coding the primitives of the proprietary application into a special format and storage of the primitives; means for launching an application under the open system (UNIX) to decode and execute the function called by the primitive and to return the result; means for decoding the result; means for ensuring the synchronization of the accesses to the shared memory.

Device for the utilization of exported pseudosockets

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. The first machine (PS) then requests the input parameters of the function to be executed, which are known to the relay machine (RE), then executes the function upon their reception by furnishing the result as an output parameter to the second machine (CL) via the relay machine (RE).
