Does it meet performance and failover time requirements?
它满足性能和故障转移时间要求吗？
If we had to add more disks, this would increase the failover time.
如果我们必须添加更多磁盘，那么将增加故障转移时间。
Therefore, you should use concurrent access for faster failover time.
因此，您将使用并发访问以获得更快的故障转移时间。
We can also have the concurrent access on for the raw disks, and that even further reduces failover time.
我们还可以对原始磁盘进行 并发访问，甚至可以进一步减少故障转移时间。
We succeeded in achieving the goal of this POC because the measured failover time was approximately 60 seconds in most cases.
我们成功达到了此POC的目标，因为大多数情况下所测的故障转移时间约为60秒。
For faster failover time the best configuration is to use DMS tablespaces and raw devices, and even better allow concurrent access to the disks.
为了获得更快的故障转移时间，最佳配置是使用dms表空间和原始设备，甚至最好允许对磁盘的并发访问。
We wanted to test for performance, reliability, stability and the requirement to achieve the fastest failover time with a target failover time below 60 seconds.
我们需要测试性能、可靠性、稳定性，并需要取得最快的故障转移时间，其目标故障转移时间要少于60秒。
Raw device usage also improves failover time in case the database is large, because during failover the operating system does not have to do a file check to the file system (FSCK).
如果数据库很大，那原始设备的使用也能减少故障转移时间，因为进行故障转移时，操作系统不必对文件系统进行文件检查(fsck)。
With database managed space (DMS) and raw device, we can decrease the time to fail over the disk resources, because there will be no checking of disks during failover.
通过数据库管理的空间(DMS)和原始设备，我们可以减少磁盘资源的故障转移时间，因为在故障转移时将不会进行磁盘检查。
Failover is another feature of this, meaning that at any time, one of the nodes in the cluster could fail, and the state of a user's session would survive on another machine in the cluster.
故障转移是群集的另一个功能，表示在任何时候，如果群集中的某个节点发生故障，用户会话的状态会在群集中的另一台机器上保留。
Because failover always anticipates failback, it is usually worth the time to create automation or processes that promote consistent, reliable, and repeatable execution of the activities.
由于故障转移始终预期要退回，因此花时间创建可促进活动一致、可靠和可重复执行的自动化或流程是值得的。
So as the number of installed SCA applications increases, the time it takes to start or failover the me also increases, but at a quicker rate.
因此，随着所安装的SCA应用程序的数量的增加，ME启动或故障转移所花的时间也会增加，但是后者增加速度会更快一些。
This setting can be reset by failover, preferred server change, unreachable cache file, replication interval setback, or any other time you need to synch with a new server mail file.
在以下情况下可能重新设置此设置：故障转移、首选服务器更改、缓存文件不可访问、复制间隔错误，或者在其他任何需要与新的服务器邮件文件进行同步时。
Opening the physical standby database read-only may lengthen the time it takes to recover from a failure or outage, because the database must be restarted after a failover.
以只读方式打开物理备库可以延长失败或中断恢复的时间，因为数据库必须在故障切换后重新启动。
Since there is only a single copy of the database, it is always in sync. The time for the failover and restart of the database engine depends on several factors.
由于只有一个数据库副本，所以它总是同步的。
Besides having access to a marketplace, Google Apps users have zero RPO (Recovery Point Objective) and instant failover for RTO (Recovery Time Objective).
除了能够访问应用程序市场，Google Apps用户还能享受到0 RPO(恢复点目标)以及即时rto的故障转移(回复时间目标)。
