The Traffic Manager can also be used in a failover system in case the primary instance isn’t available.
在主实例不可用的情况下，流量管理器也可用作灾备系统。
Failover is the planned or unplanned shutdown of the primary system and includes the accompanying task of bringing a standby node online to take over the processing load.
故障转移是主系统在计划内或计划外的关闭，并包括完成将备用节点置于在线以接管处理负载的任务。
This script is more complex because it starts multiple partitions, cleans the system, and updates some configuration parameters and files for the proper failover of each partition.
该脚本更为复杂一些，因为它要启动多个分区，清理系统，以及为每个分区进行适当的故障转移更新一些配置参数和文件。
NOTE: While this configuration supports a basic production deployment, it does not provide any redundancy for system failover nor does it provide the ability to scale up to support growing user loads.
注意：虽然该配置支持基本的产品配置，但没有提供任何系统故障恢复冗余，也不具备支持用户负载增长的扩展能力。
This can be done using known techniques, such as placing the Deployment Manager on its own system, and protecting that system with an operating system failover mechanism (for example, HACMP for AIX).
这可以使用已知的方法实现，如在自已的系统上放置部署管理器和使用操作系统故障转移机制(例如，用于AIX的HACMP)来保护系统。
System configurations support failover and disaster recovery, as primary and backup systems may be separated by many miles.
系统配置支持故障转移和灾难恢复，而主系统和备份系统可以放置在距离很远的两个位置。
This makes your system more amenable to failover.
这样做可以使您的系统更经得起故障转移。
Is manual intervention needed, or can the system failover automatically?
需要手动干预，还是系统可以自动进行故障转移？
Thus, the system will either become inconsistent or simply stop until the failover (to only one data center) of some Shared resource.
因此，系统要么变得不一致，要么完全停止，直到对某些共享资源进行了故障转移(仅转移到一个数据中心)。
This way, when failover occurs, the other members can easily assume the additional load (minus the replication traffic from the failed system).
这样，当发生故障转移时，其他成员可以轻松地承担额外的负载(减少来自失败系统的复制流量)。
Therefore, administrators do not need to do any extra work during a system failure to failover Kerberos authentication service to the backup server.
因此在系统失败时，管理员不需要做额外工作就可以将Kerberos身份验证服务故障转移到备份服务器。
If automatic failover is not desired, it is also possible to configure PowerHA to wait for direction from an system administrator.
如果不需要自动故障转移，也可以将PowerHA配置为等待系统管理员的指示。
This can be done using known techniques, such as placing the Deployment Manager on its own system, and protecting that system with an Operating System failover mechanism (for example, HACMP for AIX).
这可以使用已知的方法实现，如在自已的系统上放置DeploymentManager和使用操作系统故障转移机制（例如，用于 AIX 的HACMP）来保护系统。
The service group must have a system (or systems) designated in its SystemList attribute as a potential failover target.
服务组必须在其系统列表中指定一个系统(或多个系统)作为一个可用的故障恢复目标。
In the failover process, the data source is moved from the primary to the secondary system.
在故障转移过程中，数据源从主系统移动到辅助系统。
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)。
Simulate failover by simply stopping heartbeat on the primary system using the command shown below.
在主节点上使用下面的命令仅仅停止heartbeat来模拟故障转移(failover)。
Loosely coupled Web services are seen as a better alternative; a Web service failure doesn't disable the entire system, provided a failover Web service server is in place.
松散耦合的WebServices可以视为更好的替换方法；只要提供了备用的故障转移WebServices，某个Web Services的故障就不会让整个系统无法使用。
During a quick failover, all stable calls are lost when ap or EIN hardware, Operation System, platform software, or some application software faults occur.
在快速失败切换期间，当ap或ein硬件、操作系统、平台软件或某些应用程序软件出现故障时，所有稳定呼叫都会掉线。
Redundant memory provides the system with a failover memory bank when a memory bank fails.
冗余内存在某个内存块故障时为系统提供一个故障转移的内存块。
A failover module significance about to improve the work efficiency of the invade check system, and subdivide the class of the invade check system.
对提高入侵检测系统的工作效率，细化入侵检测的分类有一定的指导意义。
A failover module significance about to improve the work efficiency of the invade check system, and subdivide the class of the invade check system.
