ORA-01366: failed to find redo logs required for terminal apply ORACLE 报错 故障修复 远程处理

文档解释

ORA-01366: failed to find redo logs required for terminal apply

Cause: LogMiner failed to find all the expected log files required to complete the terminal apply, requested using the FINISH APPLY clause. During terminal apply, LogMiner does not wait for logs to be reGIStered. It expects all logs between the starting point and the last log on any redo branch that it will or could mine through, to be present at the mining site.

Action: Examine system.logmnr_log$ to see which logs are known to LogMiner. Then, locate or restore any missing logs and use the ALTER DATABASE REGISTER LOGICAL LOGFILE statement to register them. Alternatively, do not use the FINISH APPLY clause, but if activating a logical standby, only do this when you are sure that the missing log files can not be located and registered as this can lead to data loss.

ORA-01366:failed to find redo logs required for terminal apply错误消息官方描述为：

ORA-01366: 在终端应用恢复时，无法找到必要的重做日志。

这是由于回滚段无法在回滚段索引文件中解析时发生的，如果索引文件不存在或者索引文件中找不到必要的未发布的重做日志，就会发生此错误消息。此错误消息表示客户端未能找到所需的重做日志以完成恢复过程。

常见案例

1. 当使用外部恢复进行恢复时，其回滚段索引文件可能不存在，也有可能不包含必需的未发布的重做日志；

2. 如果_allow_resetlogs_corruption选项设置为TRUE，则可以绕过这个错误；

3. 如果在备份数据库时未拷贝重做日志，则可能导致该错误；

4. 如果恢复操作时间超过储存期，重做日志可能被释放，从而可能发生这个错误；

正常处理方法及步骤

1、使用_allow_resetlogs_corruption选项，将其设置为TRUE：

sql> alter system set “_allow_resetlogs_corruption”=TRUE scope=spfile;

2、如果备份数据库时未拷贝重做日志，则检查拷贝的备份是否存在，以避免错误的恢复操作；

3、如果重做日志可用，则请使用RMAN快照控制文件，并按照适当的步骤进行恢复。
