Because SHUTDOWN ABORT does not checkpoint the open data files, instance recovery is necessary before the database can reopen.
因为shutdownabort不会生成检查点，所以再次打开数据库时要进行实例恢复。
INACTIVE - Log is no longer needed for instance recovery. It may be in use for media recovery. It might or might not be archived.
表明例程恢复不再需要联机重做日志组，它可能已经归档也可能未归档。
In order to be ready to react quickly and efficiently to any of these type scenarios, it is recommended that you put in place a plan for instance recovery.
为了快速有效地应对这些情况，建议准备一个实例恢复计划。
After the physical restore completes, the database instance waits in fast recovery mode to restore logical logs.
在物理恢复完成之后，数据库实例处于快速恢复模式，等待恢复逻辑日志。
Although it was originally developed as a disk-cloning tool for disaster recovery, you can use it to convert a physical server instance into a VM for easy deployment into a virtualized infrastructure.
虽然该工具最早是作为灾难恢复的磁盘克隆工具开发的，但它可以被用来将一个物理服务器实例转化成一个VM，以便于部署在一个虚拟基础设施内。
The DB2 HADR stand-by server USES a third EC2 instance in a different availability zone within the US-East region as the disaster recovery site.
DB 2HADR备用服务器使用第三个EC2实例，放在美国东部地区不同访问区中，作为灾难恢复网站。
If the cause is unknown, then you should perform a full recovery of the instance.
如果原因不明，那就应当执行实例的完全恢复。
Perhaps the instance is performing some form of work, but only to help prime a recovery in the event of a failure; for example, in a High Availability Disaster Recovery (HADR) scenario.
这个实例可能正在执行某种形式的工作，而只是在出现故障事件时帮助启动恢复（例如在 HADR 场景中）。
By putting together a backup and recovery strategy for an instance, you can potentially avoid having to do a complete operating system restore when faced with a compromised instance.
通过为实例准备备份与恢复策略，可在遇到实例损坏问题时，不必进行整个操作系统恢复。
For the process and database instance failures, you can enable automatic crash recovery by verifying that the database configuration auto restart is set to on (by default, auto restart is on).
对于流程和数据库实例故障，可以通过确认已将databaseconfigurationautorestart设置为on(缺省情况下，自动重启已启用)来启用自动故障恢复功能。
As described in this section, if you know the cause of an instance failure, a complete recovery may not be necessary.
正如本部分所描述的，如果导致实例故障的原因是已知的，就不必进行完全恢复。
