Abstract: A method for activating and executing objects containing data and procedures including the steps of relaying, by a first object in a first address space, a communication from a process in a second address space to a second object in the first address space, activating, by the second object, a third object containing data and procedures in response to the relayed communication, and executing, by the activated third object, an operation in response to the relayed communication. In addition, an apparatus for activating and executing remote objects containing data and procedures including a first object in a first address space for relaying a communication from a process in a second address space to a second object in the first address space, apparatus for activating, in the second object, a third object containing data and procedures in response to the relayed communication, and apparatus for executing, in the activated third object, an operation in response to the relayed communication.

Abstract: A method, system and process for providing an improved database blocking technique for updatable and scrollable cursors is disclosed. The invention is facilitated by the operation of a process in the memory of a processor. The processor, under the control of the process, builds a reserved area in the memory of the computer. The reserved area in the memory contains an image of a portion of the information residing on disk in the database. When an application opens a cursor to a database, the type of blocking is specified for that cursor. The application issues a fetch request, and if the row is not in the block in the reserved area in the memory, then a remote procedure call is performed to get the required next block of rows and return the block containing the rows back to the application. Various lock data structures are employed to manage and control the processing.
