复制可以配置为同步或异步复制。
Replication can be configured using synchronous or asynchronous replication.
您可以选择使用同步复制或异步复制。
与地理镜像一样，这里也存在同步和异步复制两种选项。
As with geographic mirroring, there are both synchronous and asynchronous options.
这些解决方案中涉及的复制是同步复制或异步复制。
The replication involved in these solutions is either synchronous or asynchronous.
在本文中，我们了解了使用ER实现异步复制的灵活性和集群的高可用性特性。
In this article, you've learned about the flexibility of asynchronous replication using er and the high-availability features of a cluster.
通过选择同步和异步复制的数量及其区域放置，您可以在失败时平衡性能、可用性和弹性。
By selecting the number of synchronous and asynchronous replicas, and their zone placement, you can balance your performance versus your availability and resilience in the face of failures.
异步复制更快，但如果J VM在复制之前就退出，就会导致最近事务发生的变化可能会丢失。
Asynchronous replication is much faster but changes from the very latest transactions may be lost if a JVM exits before they are replicated.
在确定异构数据库复制研究的重点方向以后，本文提出了异构数据库异步复制模型。
After deciding on the key research area of heterogeneous database replication, the dissertation has proposed a asynchronous replication model for heterogeneous database.
对于异步复制，顺序是一样的，但是无需等待目标节点确认已经收到写入操作，就可以完成生产节点上的写入操作。
With asynchronous replication, order is preserved, but the write is allowed to complete without waiting for an acknowledgement from the target node that the write has been received there.
不要将此与数据库的异步复制功能混淆，因为用于异步复制数据的数据库功能效率低下，不应该予以采用。
Do not confuse this with the features of a database to asynchronously replicate, because the database feature to replicate data asynchronously is insufficient and should not be employed.
数据容灾，是指建立一个异地的数据系统复制本地数据，可采用同步或异步复制技术。本文就此进行分析。
This paper discusses the key concepts of data replication disaster recovery, synchronous and asynchronous , and makes an analysis on them.
有状态的Web服务在集群的LotusDomino环境下不能进行故障恢复，因为Lotus Domino没有提供在节点间异步复制会话和状态的功能。
Stateful Web services do not fail over in a clustered Lotus Domino environment because Lotus Domino does not offer asynchronous replication among nodes to replicate sessions and states.
但是，由于传统复制解决方案固有的异步本性，我选择了在故障转移小节描述这个场景。
However, due to the inherent asynchronous nature of traditional replication solutions, I have chosen to describe this scenario in the failover section.
此解决方案的优势在于，它提供从非尽力服务的异步服务到有保证的同步事务复制的所有选择。
The advantage of this solution is that it provides everything from asynchronous replication that is not best effort to guaranteed synchronous transactional replication.
复制是一个异步的过程，不能保证故障转移期间两个副本之间所有数据都是一致的。
Replication is an asynchronous process and can not guarantee during a failover that all data is consistent between copies.
它是一个异步的、基于日志的过程，允许您将数据从一个位置复制到另一个位置，同时使第二个位置的数据和第一个位置的相同。
It's an asynchronous, log-based process that permits you to copy data from one location to another, keeping the data in the second location identical to the first.
标准的复制模型是可升级的且提供使用异步传输的“某时”仓库的同步。
The standard replication model is scalable and provides "some time" synchronization of repositories using asynchronous transportation.
它由一对服务器组成—主服务器和HDR备用服务器—并且同时支持异步和同步复制模式。
It consists of a pair of servers - the primary and the HDR secondary - and supports both synchronous and asynchronous replication modes.
首先，复制是异步进行的。
对于1 -safe设置，事务在主服务器上提交后，控制权立即回到应用程序。复制到备用服务器的操作是异步进行的。
With the 1-safe setting, control returns to the application immediately after a transaction is committed on the primary server; replication to secondary server is done asynchronously.
可靠性：就像WebSphereeXtremeScale复制和处理应用程序对象那样，同样的功能也被应用到网格中的异步消息。
Reliability: Just as WebSphere eXtreme Scale replicates and handles application objects, the same function is applied on the asynchronous messages within the grid.
复制可以是同步或异步的；将数据写入WebSphereeXtremeScale缓存时区别很重要。
Replicas can be synchronous or asynchronous; the distinction is important when data is written to a WebSphere eXtreme Scale cache.
通过磁盘复制系统，将捕获主要数据中心的状态数据的快照并以异步方式传输到灾难数据中心。
With this disk replication system, snapshots of the state of the primary data center are captured and asynchronously transferred to the disaster data center.
如果选择这种方法，则必须清楚或考虑复制本身的异步性。
You must be aware of or account for the asynchronous nature of replication if this is your chosen method.
在样例中，网格配置为当另一个容器可用时异步执行消息的单一复制。
In the sample as packaged, the grid is configured to synchronously perform a single replication of the message if another container is available.
本文前面探究了节点之间复制数据的各种方法(尤其是这两种—完全同步和完全异步)。
Earlier, this article explored the various methods for replicating data between nodes (two in particular-fully synchronous and asynchronous).
