DETERMINING AND REGISTERING PARTICIPANTS IN A DISTRIBUTED TRANSACTION IN RESPONSE TO COMMENCING PARTICIPATION IN SAID DISTRIBUTED TRANSACTION

A mechanism and system are provided for making available information that identifies participants of a distributed operation by registering the information with a name service. Once the participant information has been registered with the name service, the name service supplies the information to entities that request it. An example of a distributed operation is a distributed transaction executed by two or more database servers.
