Abstract: A method of journaling changes to system objects. A dummy function is substituted for a system function. The system function is executed under operation of the dummy function. Copies of system objects changed by execution of the system function are generated for journaling. Execution of the dummy function is then completed. Preferably the system objects are OS/400 system objects. The system objects may be program objects, configuration objects, queues and space/memory mapped objects. The copies of the system objects may be journaled for replication on another system. A system and software for journaling changes to system objects are also disclosed.

Abstract: A method of replicating a database from a source computer system to a target computer system comprising: i) receiving journal entries from the source computer; and ii) allocating program components to process journal entries; and update the target database, wherein a control program allocates tasks to program components and controls the program components substantially without program components interacting with one another.

Abstract: Un procedimiento de réplica de una base de datos para replicar datos desde un sistema de origen (1) a unsistema objetivo (6) que comprende las etapas de:i) recepción (7) de las entradas del diario desde el sistema de origen (1) en el sistema objetivo (6) donde cadauna de las entradas del diario está asociada con un objeto de la base de datos que identifica una tabla de labase de datos que tiene una o más filas a actualizar, en donde el procedimiento está caracterizado por:ii) extracción de la información de procesamiento desde una base de datos de asignación donde la informaciónde procesamiento determina si los objetos de la base de datos necesitan agruparse con otros objetos de la basede datos,iii) procesamiento de las entradas del diario de acuerdo con la información de procesamiento extraída por a) laidentificación del grupo de serialización (8) asociado con el objeto de la base de datos y b) la asignación de lasentradas del diario al grupo de serialización identificado (8) en base a la información de procesamiento en labase de datos de asignación, en donde las entradas del diario del mismo tipo o relacionados con otras entradasdel diario se procesan en el mismo grupo de serialización (8) yiv) el procesamiento de los grupos de serialización (8) con las entradas del diario asignadas en paralelo parareplicar los datos desde el sistema de origen (1).

Abstract: The invention relates to data processing methods and systems including: a method of database replication in which information strings are assigned to serialisation groups for processing. A method of memory management in which data is read from a storage space area whilst no data is written to it. A method of replicating a database in which a dynamic table is created to provided processing information for database members. A method of replicating a database wherein tasks are allocated to program components without program components interacting.
