Abstract: A computer system and process efficiently provides resource recovery for a failure during a commit procedure. An application is run on a processor and requests a work operation involving a resource such as a protected conversation with another application in a different real machine. A commit procedure is begun for the work request, and if the commit procedure fails before completion, the following steps are taken to optimize the use of one or both of the applications. At some time after the commit procedure fails, a return code is sent to at least the application that initiated the commit indicating the result of the application commit order and that the application can continue to run and does not have to wait for resynchronization (recovery). Then, while the initiating application continues to run and do other useful work, resynchronization is implemented in parallel, asynchronously.

Abstract: A computer system or network tailors scopes of commit processing by using local work unit identifiers and more global logical unit of work identifiers. The local work unit identifiers are used to identify the scope of commit processing within each execution environment, and the logical unit of work identifiers are used to identify related work units of different execution environments. The related work units are coupled to each other by a protected conversation between the execution environments.
