您要查找的是不是：
- Extracting the data dictionary into the redo log files. 将数据字典摘取到重做日志文件中。
- Recovering from the loss of an only active redo log group. 从惟一活动重做日志组的丢失中恢复。
- Recovering from the loss of the current redo log group. 从当前重做日志组的丢失中恢复。
- It is defined as "istance" between is and the end of the redo log. 它也被定义为从该位置到日志文件结束点的距离。
- Multiplex the redo log files and put group members on different disks. 分组放在不同磁盘上。
- The primary function of the redo log is to record all changes made to data. 重做日志的主要功能是记录对数据的操作。
- During log switch, online redo logs will be archived. 在日志切换期间,将归档联机重做日志。
- Lost of online redo logs before they are archived. 在对联机重做日志进行归档之前,这些日志丢失了。
- Now that you are confirmed that the lost redo file is an ACTIVE redo log, shutdown the database - shutdown immediate. 既然您确认丢失的重做文件是ACTIVE重做日志,那么现在就可以关闭数据库shutdown immediate。
- Now that you are confirmed that the lost redo file is an INACTIVE redo log, shutdown the database - shutdown immediate. 既然您已经确认丢失的重做文件是INACTIVE重做日志,那么现在可以关闭数据库shutdown immediate。
- Online redo log files have to be multiplexed before putting the database in ARCHIVELOG mode. 当然有多个。。。但是不归档模式也有多个。。。
- The information stored in the SGA is divided into several types of memory structures, including the database buffers, redo log buffer, and the shared pool. SGA的内容可以被分为以下几类内存结构，包括数据库缓冲区，重做日志缓冲区，和共享池。
- If a failure prevents modified data from being permanently written to the datafiles, then the changes can be obtained from the redo log, so work is never lost. 如果某种故障导致无法将修改过的数据永久的写入数据文件，那么这些修改内容可以从重做日志中获得，用户已完成的任务不会丢失。
- The operation of writing all data in the buffers of the SGA to the datafiles and redo log files is skipped.Refer to Database and Instance Startup and Shutdown. 特别说明：由于各方面情况的不断调整与变化，商城学网所提供的所有考试信息仅供参考，敬请考生以权威部门公布的正式信息为准。
- They could also contain uncommitted changes that were either saved to the datafiles before the failure, or were recorded in the redo log and introduced during cache recovery. 但数据文件还有可能出现未提交的修改。这些修改可能是在故障前被写入数据文件的，也可能是记录在重做日志中并在缓存恢复时被写入数据文件的。
- Redo log group not archived. 时应该增加日志组。
- Note: Sometimes, if more buffer space is needed, LGWR writes redo log entries before a transaction is committed. These entries become permanent only if the transaction is later committed. 有时,如果重做日志缓冲区内空间不足,LGWR进程会在事务提交前就将重做日志条目写入磁盘。这样的重做日志条目只有在相关事务提交后才能永久地存储。
- If you know that an archived redo log group has been damaged, immediately back up all datafiles so that you will have a whole database backup that does not require the damaged archived redo log. 实际上，归档日志文件丢失并不可怕，只要及时发现，并且目前还没有文件损坏，还不需要进行完全恢复，则马上做一个全库备份，则丢失的归档日志文件不再需要。
- If the redo log buffer fills, or another transaction commits, LGWR flushes all of the redo log entries in the redo log buffer to a redo log file, even though some redo records may not be committed. 例如如果重做日志缓冲满了，或者有其它的事务提交了。LGWR进程会把所有在重做日志缓冲中的重做日志事项写入重做文件，即使是一些重做记录可能还没有提交。
- 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.
