Method And Systems For Providing Transaction Support For Executable Program Components
Methods and systems are described for providing transaction support for executable program components. In one embodiment, transaction information is associated with an instruction included in an executable addressable entity included in an executable program component generated from source code written in a programming language, wherein the transaction information is independent of the source code and the programming language. Further, an access to the instruction is detected for executing by a processor. A transaction operation to perform in association with the executing of the instruction is determined based on the transaction information associated with the instruction. The transaction operation is performed in association with the executing of the instruction, wherein the transaction operation is performed by a program component other than the executable program component including the executable addressable entity.

8 . The method of claim 1 wherein the transaction operation includes at least one of generating a new transaction, committing and terminating a transaction, aborting a transaction and rolling back changes made by the transaction, and invoking a specified event handler.
9 . The method of claim 1 wherein the transaction operation is performed at least one of before the executing of the instruction, during the executing of the instruction and after the executing of the instruction.
10 . A system for providing transaction support for executable program components, the system comprising:
