A method of resolving a transaction by a participant of a plurality of participants, the method comprising:

• communicating with the plurality of other participants, a coordinator, and a distributor to determine whether to commit a transaction;
• determining whether communication with the coordinator is available;
• determining whether communication with the distributor is available;
• and
• if communication with the coordinator and the distributor are not available, sending a voting message to each of the plurality of other participants indicating whether to commit the transaction and receiving voting messages from the plurality of other participants indicating whether to commit the transaction.

• means for determining whether communication with the coordinator is available;
• means for determining whether communication with the distributor is available;
• and
• means for sending a voting message to each of the plurality of other participants indicating whether to commit the transaction and receiving voting messages from the plurality of other participants indicating whether to commit the transaction if communication with the coordinator and the distributor are not available.

A method of resolving atomic transactions within a distributed system, the method comprising:

• sending messages from a plurality of participants to a coordinator indicating that the plurality of participants are prepared for an atomic transaction;
• sending a message from the coordinator to a distributor indicating that the plurality of participants are ready to commit the atomic transaction;
• sending messages from the distributor to the plurality of participants instructing the plurality of participants to commit the atomic transaction;
• sending messages among the plurality of participants indicating that the plurality of participants committed the atomic transaction;
• and
• sending messages from the plurality of participants to the coordinator indicating that the plurality of participants committed the atomic transaction.

A coordinator configured to participate in resolving a transaction within a distributed system, the coordinator comprising:

• a first module configured to receive from a plurality of participants messages indicating that each of the plurality of participants are prepared to commit a transaction;
• a second module configured to send a message to a distributor indicating that the distributor should send a commit message to the plurality of participants instructing the plurality of participants to commit the transaction;
• and
• a third module configured to receive messages from each of the plurality of participants indicating that the plurality of participants have committed the transaction.
