晚上接到用户电话，DG备机报错无法正常同步。ORA-00600: internal error code, arguments: [2619], [84747]，了解到之前出现磁盘空间满，已经人为删除处理过；这是一个典型的DG空间满后的问题，官方文档ORA-600[2619] During Physical Standby Recovery (Doc ID 1138913.1)对此有说明；总结理解一下，问题原因为磁盘空间满，导致归档日志未完全写入而出现损失，DG备机的MRP进程无法使用此归档日志。了解了原理后，处理就比较简单了。方法有两种：

方法1.mos文章上的方法，释放磁盘空间，从主库复制报错的归档日志到备机，再进行恢复。--->>>这种方式其实在操作的多时略烦琐；

方法2：使用rman进行归档删除(delete noprompt archivelog until time 'sysdate-2';)，再使用crosscheck archivelog all;将损坏的归档日志标记EXPIRED，使用delete noprompt expired archivelog all;命令删除损坏的归档日志；此时通常会自动重新传之前错误的归档日志，后续有缺少日志时在GAP机制下也可以自动传。方法2在顺利情况下就是会3条命令刷一下，然后就等着自动恢复即可。

本次问题使用这方法处理，三条命令刷上，问题顺利解决。相关日志如下：

1.DG备机alert日志中的RA-00600: internal error code, arguments: [2619], [84747]报错信息

2.对于日志操作的判断

at Apr 10 22:16:20 2021   =====>>>>报84747号日志文件操作
archivelog header validation failure for file /oracle/arch/1_84747_958258329.dbf

3.RMAN命令进行校验与删除EXPIRED状态日志

校验结果：

4.删除后自动重新传输归档日志
