PROCESSING TRANSACTIONS IN A SYNCHRONIZED REPLICATION SYSTEM |
| 摘要 |
Embodiments of the present disclosure provide a method, a computer program product and apparatus for processing transactions in a synchronized replication system, wherein the method comprises, at a source site in the synchronized replication system: serializing commits of transactions in the synchronized replication system so that only one of the transactions can be committed at the same time; in response to initiating the commit of the one transaction, generating a log for each of transactions that are ongoing in the synchronized replication system, so as to record impact of all operations of a respective transaction on the synchronized replication system; marking transactions for which the logs have been generated; and completing commits of the marked transactions. |

1. A method for processing transactions in a synchronized replication system, comprising, at a source site in the synchronized replication system:
serializing commits of transactions in a synchronized replication system so that only one of the transactions can be committed at a same time; in response to initiating the commit of the one transaction, generating a log for each of transactions that are ongoing in the synchronized replication system, so as to record impact of all operations of a respective transaction on the synchronized replication system; marking transactions for which the logs have been generated; and completing commits of the marked transactions. |
