A method, apparatus and program product are provided for servicing a production program. A mirror program is dynamically created using source code associated with the production program. The mirror program includes enhanced serviceability functionally relative to the production program that generates service information relevant to the production program. The mirror program executes while the production program remains in an active state such that the production program may be serviced using service information generated by the mirror program. The source code used to compile the production program is compared to a base line copy of the source code. Portions of the source code that differ from the base line copy of the source code are stored. The stored portions of the source code are associated with a unique identifier which is saved with the compiled production program.
