Debugging of a transaction across multiple processors is facilitated by having debug information follow the transaction from processor to processor. The transaction can be debugged across processors without predefining the transaction path, and without performing a debug registration process between the client controlling the debugging and each processor of the multiple processors.

Debugging transactions across multiple processors

A program having a plurality of concurrently executing versions is debugged. A version of the program to be debugged is selected from the plurality of versions of the program, and that selected version is debugged. As one example, the selection is responsive to the receipt of at least one task of the computing environment that is associated with the version to be debugged. The debugging of the selected version does not affect other versions of the program, other programs executing within the computing environment or other tasks using that version.
