您要查找的是不是:
- Standby database technology, clustering, parellel server option will be presented. 应准备备用数据库技术,CLUSTERING和并行服务器选件。
- Two effective methods of maintaining high availability for Notification Services applications are failover clustering or warm standby database servers. 有两种维护Notification Services应用程序的高可用性的有效方法:故障转移群集或备用数据库服务器。
- The value is an Oracle Net service name, which is assumed to be configured properly on the standby database system to point to the desired FAL server. FAL_SERVER参数为备用数据库指定了取得归档日志文件的数据库服务器位置。这个值通常用数据库服务器的网络服务名来表示,并且,这个数据库服务器的网络服务名需要在备用数据库上正确的被配置。:FAL_SERVER specifies the FAL (fetch archive log) server for a standby database.
- For Database Redundancy purpose, CRF (Continuous Roll Forward) Mechanism has been used for data redundancy purpose between the active and standby database server. 为具有数据库冗余,CRF(持续向前滚动)机制被用作活动与待机数据库服务器之间的数据冗余。
- Bring the standby database server online and fully recover the instance and application databases. 将备用服务器联机并完全恢复实例和应用程序数据库。
- If you require multiple standby databases, you can use log shipping alone or as a supplement to database mirroring. 如果需要多个备用数据库,可以单独使用日志传送或将其作为数据库镜像的补充。
- As the remote file server (RFS) process writes the redo data to standby redo log files on the standby database, apply services can recover redo from standby redo log files as they are being filled. Figure 7-1 展示了一个data guard配置情况,包含一个本地归档位置和一个远程归档位置,随着rfs进程将重做数据写入到备用数据库的备用日志文件中,应用服务将会从备用日志文件恢复重做数据,当它们被填写满的时候:shows a Data Guard configuration with a local destination and a standby destination.
- When performing Redo Apply, a physical standby database can use the real-time apply feature to apply redo directly from the standby redo log files as they are being written by the RFS process. 默认情况下,对备用数据库应用的重做数据来自于备用数据库上的归档日志文件。当执行重做数据应用时,通过使用real-time apply参数,备用数据库可以直接应用来自备用日志文件的重做数据,而不是来自于归档日志文件,当然,备用日志文件中的这些重做数据是由rfs进程写进去的。
- For logical standby databases, the changes are applied using SQL regenerated from the archived redo logs. 对于逻辑备份数据库,将利用归档重做日志重新生成SQL来应用修改。
- Design and application of backup and recovery based on standby database 基于待用数据库的备份与恢复方案设计与应用
- SQL> alter database recover managed standby database using current logfile disconnect; 要创建多个后备数据库,重复这些步骤即可。
- alter database recover managed standby database using current logfile disconnect from session; 在备机端:启动数据库到实时恢复管理模式
