All domain controllers need to be able to replicate at least once during this period or they become worse than useless; they create an opportunity for USN rollback.
在这段时间内,所有域控制器都必须能至少复制一次,否则不仅于事无补,而且会让事情更糟;它们为usn回滚创造了机会。
In such cases, the USN value has a special value that signals the CE server to skip the USN check.
在这些情况中,US n值有一个表示CE服务器跳过usn检查的特殊值。
The second cause of USN rollback occurs when a domain controller has been restored using an unsupported method, most frequently using a disk cloning or imaging tool.
导致发生usn回滚的第二个原因是使用不受支持的方法(最常使用的是磁盘克隆或映像工具)还原了域控制器。
So if a DC has a USN of 1000 at 11:00 a.m., and 1005 at 11:30 a.m., you know that 5 changes have been made to the Active Directory database on that DC.
因此如果某DC的USN在上午11:00时为1000,而在上午11:30时为1005,您就会知道已在该DC上对ActiveDirectory数据库进行了5次更改。
If you later fetch or refresh any properties from the server, the current USN is obtained as well.
如果您稍后从服务器获取或刷新任何属性,也会获取当前usn。
If the USN value sent does not match the USN value currently persisted in the repository, the ce server knows that a change was made (by some other caller) since the object was fetched.
如果发送的US n值与储存库中储存的值不匹配,CE服务器就知道已经(由其他调用方)进行了更新,因此该对象已被获取。
You「re still going to have to make the same number of server round-trips to update the dispenser object or fetch the USN value.
您仍然需要多次到达服务器以更新分发器对象或获取usn值。
Step 4: DC1 sends DC2 the change that corresponds with USN 3001, that is, the object that was created on DC1 in Step 2.
步骤4:dc1向DC2发送与usn 3001相对应的更改,即在步骤2中在DC1上创建的对象。
Again, if this USN is the same as the USN of the DC that is replicating the change, then this is an originating write.
同样,如果此usn与复制更改的DC的USN相同,就表明这是原始写入。
DC1」s UTDV table (shown in Figure 6), indicating the highest originating USN that it has received from all DCs including DC3.
DC1的UT dv表(如图6所示),指示已从所有DC(包括DC3)接收的最高原始usn。
Each domain controller maintains a USN that is specific to that domain controller.
每个域控制器都维护特定于该域控制器的USN。
Let「s further say that DC1」s current USN is 3000, DC2「s current USN is 4500, and that these two DCs are fully up-to-date with one another as we begin our example.
我们再假设DC1的当前usn为3000,dc2的当前usn为4500,在开始我们的示例时两个DC对彼此而言都已处于最新状态。
Actually, the CE progression pattern for USN is only vaguely specified.
事实上,ce对usn的递增模式的指定是模糊的。
One underlying cause of USN rollback has to do with the way that object deletions are processed in the Active Directory multi-master environment.
导致usn回滚的一个基本原因与在ActiveDirectory多主机环境中处理删除对象的方式有关。
The incrementing of the USN is not, strictly speaking, under your control.
严格来说,USN的递增是不受我们控制的。
Step 2: An administrator creates a new object on DC1, and DC1」s USN is incremented to 3001, as shown in Figure 2 .
步骤2:管理员在DC1 上创建了一个新对象,DC1的USN增加到了 3001,如图2所示。
USN rollback can occur because these tombstoned objects don「t hang around indefinitely.
因为这些逻辑删除对象不会无限期保留,所以可能会发生usn回滚。
When you fetch an object from the server, the USN is also fetched and brought to the client side.
当您从服务器获取一个对象时,USN也被获取并传递到客户端。
But this is not the only way that a DC」s USN can be incremented.
但这并不是增加dc的usn的唯一方式。
The CE server increments the USN whenever the persisted object is updated, not just when someone has requested a new sequence number.
除了某人请求新的序列号之外,CE服务器还在每次更新持久化对象之后都将 USN 增加 1。
