All Implemented Interfaces:

ORemoteTask

public class OCompleted2pcTaskV1
extends OCompleted2pcTask

Task to manage the end of distributed transaction when no fix is needed (OFixTxTask) and all the locks must be released. Locks are necessary to prevent concurrent modification of records before the transaction is finished.
This task uses the same partition keys used by TxTask to avoid synchronizing all the worker threads (and queues).
