Abstract
A method and apparatus are provided for using a resource manager to coordinate the committing of a distributed transaction. According to the method, a first set of changes is communicated to a first resource manager. In communicating the first set of changes, the changes are directly communicated to the first resource manager without being received at a second resource manager. A second set of changes is communicated to the second resource manager. In communicating the second set of changes, the changes are directly communicated to the second resource manager without being received at the first resource manager. Either the first resource manager or the second resource manager is selected as a committing coordinator. A commit request message is transmitted to the committing coordinator to request that the first set of changes be committed at the first resource manager and that the second set of changes be committed at the second resource manager. In response to receiving the commit request message, the committing coordinator causes, as an atomic unit of work, the first set of changes to be committed at the first resource manager and the second set of changes to be committed at the second resource manager.
