摘要： A method and apparatus for propagating and managing data, transactions and events either within a database, or from one database to another is provided. In one embodiment, messages are propagated from a source to a first queue and a second queue with the queues associated with the same database. The connection from the source to each queue maintains its own propagation job. This method could also be employed with cluster databases.

摘要： An approach for reducing transport of messages between nodes of a multi-node system is presented wherein a message queue is associated with a queue service, and based on which node the message queue resides, one of the nodes is registered as hosting the associated queue service. In response to a client attempting to connect and requesting a particular queue service, the client is caused to connect to the node on which the queue service resides.

摘要： Techniques are provided for maintaining high propagation availability for non-persistent messages. Destination-to-instance mapping information is provided to a listener process for a cluster database. The destination-to-instance mapping indicates the current owner instance of each single-instance destination within the cluster database. To establish a connection to a single-instance destination, a sending process sends a connection request to the global listener. The connection request identifies the desired destination queue, but not the owner instance of the queue. The global listener for the cluster database uses the destination-to-instance mapping to determine which instance is the current owner of the specified queue, and establishes a connection between the sending process and the appropriate owner instance.

摘要： A buffered message queue architecture for managing messages in a database management system is disclosed. A “buffered message queue” refers to a message queue implemented in a volatile memory, such as a RAM. The volatile memory may be a shared volatile memory that is accessible by a plurality of processes. The buffered message queue architecture supports a publish and subscribe communication mechanism, where the message producers and message consumers may be decoupled from and independent of each other. The buffered message queue architecture provides all the functionality of a persistent publish-subscriber messaging system, without ever having to store the messages in persistent storage. The buffered message queue architecture provides better performance and scalability since no persistent operations are needed and no UNDO/REDO logs need to be maintained. Messages published to the buffered message queue are delivered to all eligible subscribers at least once, even in the event of failures, as long as the application is “repeatable.” The buffered message queue architecture also includes management mechanisms for performing buffered message queue cleanup and also for providing unlimited size buffered message queues when limited amounts of shared memory are available. The architecture also includes “zero copy” buffered message queues and provides for transaction-based enqueue of messages.
摘要翻译：公开了一种用于管理数据库管理系统中的消息的缓冲消息队列架构。 “缓冲消息队列”是指在诸如RAM的易失性存储器中实现的消息队列。易失性存储器可以是可由多个进程访问的共享易失性存储器。缓冲消息队列架构支持发布和订阅通信机制，消息生成器和消息消费者可以彼此分离并且彼此独立。缓冲消息队列体系结构提供了持久性发布 - 订阅者消息系统的所有功能，而无需将消息存储在持久存储中。缓冲消息队列架构提供更好的性能和可扩展性，因为不需要持续的操作，并且不需要维护UNDO / REDO日志。只要应用程序是“可重复的”，发布到缓冲消息队列的消息至少发送一次，即使发生故障。缓冲消息队列架构还包括用于执行缓冲消息队列清理的管理机制，并且还用于当有限量的共享存储器可用时提供无限大小的缓冲消息队列。该架构还包括“零拷贝”缓冲消息队列，并提供基于事务的消息队列。

摘要： Techniques for propagating messages in a distributed system are provided. A set of messages enqueued in a source queue are sent to one or more destination queues. An acknowledgement is received from each of the one or more destination queues, where the acknowledgement indicates which messages of the set of messages have been consumed at the particular destination queue. Based on the acknowledgements, one or more messages of the set messages are ceased to be maintained in the source queue.

摘要： One embodiment of the present invention provides a system that facilitates accessing communication queues using a public network. The system operates by first generating a message or messages at a client. The system then formats these messages in a publicly available format. Next, the system communicates the messages across the public network to a web server. The web server receives the messages and transforms the messages to a database specific format. The web server then passes the messages to a queue within a database server across a proprietary network. In one embodiment of the present invention, the system includes queue-to-queue propagation with exactly once guarantees and recovery from failures. In one embodiment of the present invention, the system includes transactional guarantees when a client accesses a queue.
摘要翻译：本发明的一个实施例提供一种便于使用公共网络访问通信队列的系统。系统首先在客户端生成消息或消息。然后，系统以公开可用的格式来格式化这些消息。接下来，系统通过公共网络将消息传送到web服务器。 Web服务器接收消息并将消息转换为数据库特定格式。然后，Web服务器通过专有网络将消息传递到数据库服务器内的队列。在本发明的一个实施例中，系统包括具有一次保证的队列到队列传播和从故障恢复。在本发明的一个实施例中，当客户端访问队列时，系统包括事务保证。
