    Abstract: Embodiments of the present invention relate to asynchronously replicating data in a distributed computing environment. To achieve asynchronous replication, data received at a primary data store may be annotated with information, such as an identifier of the data. The annotated data may then be communicated to a secondary data store, which may then write the data and annotated information to one or more logs for eventual replay and committal at the secondary data store. The primary data store may communicate an acknowledgment of success in committing the data at the primary data store as well as of success in writing the data to the secondary data store. Additional embodiments may include committing the data at the secondary data store in response to receiving an instruction that authorizes committal of data through a identifier.

    Abstract: Embodiments of the present invention relate to synchronously replicating data in a distributed computing environment. To achieve synchronous replication both an eventual consistency approach and a strong consistency approach are contemplated. Received data may be written to a log of a primary data store for eventual committal. The data may then be annotated with a record, such as a unique identifier, which facilitates the replay of the data at a secondary data store. Upon receiving an acknowledgment that the secondary data store has written the data to a log, the primary data store may commit the data and communicate an acknowledgment of success back to the client. In a strong consistency approach, the primary data store may wait to send an acknowledgement of success to the client until it receives an acknowledgment that the secondary has not only written, but also committed, the data.

    Abstract translation: 本发明的实施例涉及在分布式计算环境中同步复制数据。 为了实现同步复制，可以考虑最终一致性方法和强一致性方法。 收到的数据可能会写入主数据存储的日志，以便最终提交。 然后可以用诸如唯一标识符的记录对数据进行注释，这有助于次要数据存储器上的数据的重放。 在收到辅助数据存储已经将数据写入日志的确认之后，主数据存储可以提交数据并将成功确认传回到客户端。 在强一致性方法中，主数据存储可以等待向客户端发送成功确认，直到其接收到确认次要不仅写入但已经提交的数据。

    Abstract: An asynchronous peer-to-peer data replication method implemented within a replication cluster comprising at least one master node and at least a first client node includes entering an update in a data volume of the master node and storing the update in a master node storage. Next, updating a first active session in a master log and then sending a first message from the master node to the first client node. The first message comprises a first message content and first "piggybacked" data indicating that the first active session in the master log was updated. Next, receiving the first message by the first client node, registering that the first active session in the master log was updated and signaling internally that the first active session in the master log was updated. Next, sending an update request from the first client node to the master node, processing the update request by the master node and sending the update to the first client node. Finally, receiving the update by the first client node and updating the first active session in a first client log.

    Abstract: A method of journaling changes to system objects. A dummy function (6) is substituted for a system function (12). The system function (12) is executed (13) under operation of the dummy function (6). Copies of system objects (16) changed by execution of the system function are generated (17) for journaling (20). Execution of the dummy function (6) is then completed. Preferably the system objects are OS/400 system objects. The system objects may be program objects, configuration objects, queues and space/memory mapped objects. The copies of the system objects may be journaled for replication on another system. A system and software for journaling changes to system objects are also disclosed.
