Method, system and program products for providing efficient syncpoint processing of distributed transactions

摘要

Syncpoint processing is performed for a distributed transaction. The distributed transaction includes a plurality of units of recovery, and syncpoint processing is performed for at least a portion of the units of recovery, without passing messages between the units of recovery of the at least a portion of the plurality of units of recovery. Instead, syncpoint processing (including transactional logging) is controlled by one syncpoint manager associated with one of the units of recovery, and that unit of recovery collects information representative of the other units of recovery.
