Multiprocessing transaction recovery manager

A method of operating a multiprocessing transaction recovery manager, in communication with a transactional application manager and a resource manager, comprising the steps of:

• receiving and storing, by a threadsafety indicator, a positive threadsafety data and a non-positive threadsafety data of at least one transactional component managed by one of said transactional application manager and said resource manager;
• performing, by a commit protocol component, commit processing for said at least one transactional component;
• and
• responsive to the positive threadsafety data, selecting, by a thread selector, a single thread for said commit processing to be performed by said commit protocol component.

A computer program product for managing the application assignments to processing threads, the computer program product comprising:

• a computer readable storage device having computer readable program code stored thereon, the computer readable program code comprising:
• first program instructions to receive, by a threadsafety indicator, a positive threadsafety data and a non-positive threadsafety data of at least one transactional component, wherein the positive threadsafety data and non-positive threadsafety data is managed by one of the transactional application manager and the resource manager;
• second program instructions to perform commit processing, by a commit protocol component, for the at least one transactional component;
• third program instructions to select, by a thread selector, a single thread for commit processing to be performed by the commit protocol component, based on the positive threadsafety data;
• and
• wherein the first and second program instructions are stored on the computer readable tangible storage device, and the computer readable storage device is not a signal per se.
