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.

1-45. (canceled)
A method of journaling changes to system objects including the steps of:
- i) substituting a dummy function for a system function;
- ii) executing the system function under operation of the dummy function;
- iii) generating copies of system objects, changed by execution of the system function, for journaling;
- and
- iv) completing execution of the dummy function.
A method of journaling changes to system objects including the steps of:
- v) executing a system function during which changes to system objects occur;
- and
- vi) journaling changes to system objects during execution of the system function.
A system for journaling changes to system objects including:
- vii) 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
- viii) memory for use by the processor during execution.
