ORA-16047: DGID mismatch between destination setting and target database

做DG的时候 主库两个节点无法把日志传到备库上

SQL> select dest_name,status,type,database_mode,protection_mode,destination,applied_seq#,db_unique_name from v$archive_dest_status;

                                                                                    og

发现 STATUS 非 VALID状态。

select dest_id,error from v$archive_dest;

ORA-16047: DGID mismatch between destination setting and target database

看来没有把日志传过去

查看 ALTER.ORA日志

检查 log_archive_dest_2 设置

SQL> show parameter LOG_ARCHIVE_DEST_2



NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

log_archive_dest_2                   string      service=shardb lgwr sync affirm valid_for=(online_logfiles,primary_role)db_unique_name=sharkdg	
 
查看备库的DB_UNIQUE_NAME 是否有错  果然设置成了SHARKDB了 
或查看log_archive_config='DG_CONFIG=()‘
 
修改了 LOG_ARCHIVE_DEST_2  SCOPE=BOTH   依旧要重启实例 否则好像并不能生效。
