Data will not be considered committed until a primary and a secondary both report success and the transaction logs are written to disk.
负载均衡器使用的是一种即时的方法，它会基于集群中各节点的当前负载来选择主副本和二级副本的位置。
The load balancer uses a just in time methodology by selecting the location of the primary and secondary replicas of a new database based on current load on nodes within a cluster.
重要的是要注意到所有的读写都发生在主副本上，所以这会对SQLAzure数据库的性能造成很大的影响。
It is important to note that all reads and writes take place on the primary replica so this can dramatically effect performance of a SQL Azure database.
辅助DNS服务器直接从主dNS服务器传输其区域信息，并在本地保留副本。
Secondary DNS servers transfer their zone information directly from the primary DNS server and keep a copy locally.
模型的主实例保持长期状态，并提供应用程序逻辑；而视图使用的副本实际上是一个可任意使用的数据访问对象。
The primary instance of the model is keeping long-term state and providing application logic; the copy used by the view is essentially a disposable data-access object.
这些服务器可能与主服务器不同步，导致新副本再次被检索。
These servers may not be synchronized with the master server, which could result in new copies being retrieved again.
您还可以复制数据库(一个主数据库，多个副本)，从而在多个CPU之间分担查询处理的负担。
You can also replicate a database (one master, many copies) to share the burden of query processing among many CPUs.
原因在于，次节点上的副本仍然指向主节点的存储库。
The reason is that the copy on the secondary node is still pointing to the repository of the primary node.
在复制架构中，一个Solr服务器充当主服务器，负责向一个或多个处理查询请求的从服务器提供索引的副本(称为snapshot)。
In a replicating architecture, one Solr server ACTS as the master server, providing copies of the index (called snapshots) to one or more slave servers that handle query requests.
在使用LDAP目录时，一种非常常见的配置是使用一个主 LDAP服务器和另外几个 LDAP 副本服务器，这种配置可以实现目录数据的负载平衡和高可用性。
When using the LDAP directory, it is very common to have one master LDAP server and a few other LDAP replica servers, so as to achieve the load-balancing and high availability of the directory data.
当故障区域重新上线时，主数据网格和副本数据网格通过目录服务在所有可用区域之间重新分布，从而最大化高可用性。
When the failed zone comes back online, the primary and replica data grids are redistributed among all of the available zones by the catalog service to maximize high availability.
使用异步副本是一个备选方案，这可以避免同步副本带来的某些性能开销，但是这不能保证与主分区始终同步。
Using asynchronous replicas is an alternative that avoids some of the performance overhead of synchronous replicas, but they are not guaranteed to be identical to the primary at all times.
如果愿意，您可以按IP地址或主机名列出多个LDAP服务器副本，并且应用服务器将在主服务器失败时自动切换到备用服务器。
If you wish, you can list multiple LDAP server replicas by IP address or hostname, and the application servers will automatically failover to one of the backup servers if the primary fails.
这样的话，即使两个ldap主服务器都停止运行了，从KDC仍然可以使用LDAP副本服务器继续提供服务。
So even if both the LDAP master servers are down, the slave KDC should continue its service by using the LDAP replicas.
如果原始分区(主分区)出现故障，将把它的一个副本提升为新主分区，然后在其他地方创建一个新副本。
If the original partition (the primary partition) fails, one of its replicas is promoted to become the new primary, and then a new replica is created somewhere else.
区域帮助目录服务确定数据网格的放置，以便主数据网格和副本数据网格被放置到不同的区域中。
Zones help the catalog service determine placement of data grids such that primary and replica data grids are placed in different zones.
对于每个主数据网格，将在不包含该主数据网格的设备上创建一个副本数据网格。
For each primary data grid, a replica data grid is created on an appliance that does not contain the primary data grid.
复制碎片是主碎片中所有数据的备份副本，它们的主要目的是从主碎片失败中恢复，提供高可用性。
Replica shards are backup copies of all the data in the primary shard, and their main purpose is to recover from a primary shard failure to provide high availability.
在主-副本设置中，在主服务器上执行所有修改，更新传播到一个或多个副本服务器。
In the master-replica setup, all changes occur on the master server and the updates are propagated to one or more replicas.
现在，用两个ldap主服务器和三个LDAP副本服务器配置从KDC。
Now configure the slave KDC with the two LDAP master servers and three LDAP replica servers.
如果包含主数据网格的设备上出现故障，则副本数据网格将升格为主数据网格。
If there is a failure on the appliance that contains the primary data grid, the replica data grid is promoted to primary data grid.
如果包含主数据网格的设备上出现故障，则副本数据网格将升格为主数据网格。
If there is a failure on the appliance that contains the primary data grid, the replica data grid is promoted to primary data grid.
