  • Automatic mode switching in a synchronous replication environment
    Patent number: 10650026
    Abstract: Disclosed in some examples is a method of database replication, the method including at a Relational Database Management System (RDMS), determining a first replication mode; identifying a triggering event; determining that the triggering event indicates a change in the first replication mode; responsive to determining that the triggering event indicates a change in the first replication mode, determining a second replication mode, the second replication mode being a different replication mode than the first replication mode; identifying a database change made by one or more database tasks; and replicating the database change to an external replication component according to the second replication mode.
    Type: Grant

  • Transaction completion in a synchronous replication environment
    Patent number: 9910733
    Abstract: Systems and methods are presented for completing transactions in a synchronous replication environment. In some embodiments, a computer-implemented method can include generating in a database server, an identifier to identify a database transaction. The method can also include transmitting the identifier to a replication server; receiving acknowledgement that the identifier is acknowledged by the replication server; storing the transaction in the database server; and executing the transaction after receiving acknowledgement from the replication server and after determining the transaction is stored in the database server; wherein transmitting the identifier to the replication server occurs in parallel with storing the transaction in the database server.
