Abstract
Discovering transaction managers participating in a transaction. A method may be practiced, for example, in a commit tree topology including a number of transaction managers to manage transactions. The transactions include a set of operations that are all performed if a transaction is completed or all aborted if a transaction is not completed. The transaction managers store transaction result information to allow recovery of a transaction in case of system failure. The method includes receiving at a first transaction manager, a token from a second transaction manager on a machine external to the first transaction manager. The token specifies that the first transaction manager is the originator of the token. The token is associated with a transaction. The first transaction manager identifies that it has not previously participated in the transaction associated with the token. A transaction manager is identified that is participating in the transaction associated with the token.
