摘要
A transaction originator node identifies multiple data elements distributed at multiple enlisted nodes to lock for a transaction managed by the transaction originator node. The transaction originator node determines which of the enlisted nodes is a first enlisted node in a lock order for the transaction and sends an update request to the first enlisted node in the lock order to lock a data element residing at the first enlisted node. The transaction originator node sends update requests to remaining enlisted nodes in the lock order to cache the update requests until the remaining enlisted nodes receive a message to perform a lock.
