Transaction participant registration with caveats

摘要

In a distributed computing system, a processing device executing a caveat enabled transaction manager registers one or more transaction participants with the transaction manager. To register a transaction participant, the caveat enabled transaction manager records an address of the transaction participant. The caveat enabled transaction manager additionally determines whether the transaction participant is associated with any transaction caveats. If the transaction participant is associated with a transaction caveat, the caveat enabled transaction manager records the transaction caveat.
