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 system for journaling changes to system objects includes: i) a processor adapted to execute a dummy function in place of a system function wherein the dummy function executes the system function and generates copies of system objects resulting from system function execution for journaling; and ii) memory for use by the processor during execution.

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.
