在 RMAN 的 RECOVER 还原过程中，RMAN 界面正常，但是检查、刷新告警日志，发现告警日志里面有 ORA-279，如下所示：

其实这个场景下，告警日志中 ORA-279 更像是“输出消息”，而不是“错误信息”，它是在提示需要请求的归档日志才能继续恢复。以前在使用 RMAN 进行 RECOVER 时没有留意过这个细节信息。顺便记录一下。以免初次遇到这个提示信息的时候，还以为出现了什么异常或错误。

[root@DB-Server  2019_02_16]$ oerr ora 279

00279, 00000, “change %s generated at %s needed for thread %s”

// *Cause: The requested log is required to proceed with recovery.

// *Action:  Please supply the requested log with “ALTER DATABASE RECOVER

//          LOGFILE <file_name>” or cancel recovery with “ALTER DATABASE

//          RECOVER CANCEL”.

Yes, you can ignore the ORA-279s. Treat them as “messages” rather then “errors”.

You need to ensure that all archivelogs are being applied by the recovery process.
