找到相关文档Note:262996.1,经过分析,产生错误的原因是由在本版本的数据库中SGA管理中存在的漏洞造成,但此错误没有对数据库的数据造成损坏及性能影响.

处理建议
1．当前版本ORACLE已经不再提供补丁支持,建议升级到高版本解决(有sr中介绍10.2中解决);
2．由于此报错并没有对数据库的数据及性能造成损坏及影响,可以忽此错误。

问题原因分析
从log_archive_dest_2 参数上可以看出默认是配置lgwr进程传输日志，但是因为备库没有配置standby redo log，所以使得启动arch传输日志，然后出现该问题，因为在传输过程中出现异常，导致arch不能继续和备库建立连接。

解决方法
查看了很多资料，给出的解决方法都是重启主库或者备库解决，我想既然是ARCH建立连接的失败，那么重启log_archive_dest_state_2参数，让arch进程重启。

SQL> ALTER SYSTEM SET log_archive_dest_state_2='DEFER' SCOPE=BOTH;

System altered.

SQL> ALTER SYSTEM SET log_archive_dest_state_2='ENABLE' SCOPE=BOTH;

System altered.

SQL> alter system switch logfile;

这个时候，查看备库日志也已经传输过去，通过修改log_archive_dest_state_2解决

使用rman基于scn实现数据库增量恢复是在dg中修复gap的时候常见的方法,其实该方法也可以使用常规的增量恢复,通过人工控制,实现数据库的某种特殊的业务需求(特殊的数据迁移).处理思路主要是获得备库的数据文件最小scn(这个scn可能是通过全备恢复或者增量恢复产生),然后基于该SCN实现数据库增量备份,然后利用该备份进行增量恢复.
