Abstract

Apparatus and method for performing an application-defined operation on data as part of a system-defined operation on the data. The apparatus and method are embodied in a distributed transaction processing system in which processes running on component systems which may be heterogeneous interact according to the client-server model. In the apparatus and method, a type is associated with the data and application-defined operations which are part of certain system-definedoperations are defined for each type. The system-defined operations which the application-defined operations are part of include allocation, reallocation, anddeallocation of buffers and sending buffers between clients and servers using remote procedure calls. In the allocation and reallocation operations, the application-defined operation is initialization; in the deallocation operation, it is uninitialization. In buffer sending, the application-defined operations include operations done on the buffer contents before sending, routing, encoding the buffer contents into a transfer syntax, operations done on the buffer contents after sending, decoding the buffer contents from the transfer syntax after receiving, and operations done on the buffer contents after receiving. Data structures in the processes associate the data and its type and a type and its application-defined operations. Servers employ a shared bulletin board data structure to indicate the types they accept.
