DG歸檔傳輸報 ORA-16191

整理文件時，發現生產端和DG端歸檔日誌沒有同步
檢查生產端:
SQL> select database_role from v$database;

經查，引數配置均沒問題

檢查DG端；

查alert日誌
[oracle@primary trace]$ tail -f alert_orcl.log |more
      returning error ORA-16191

Error 1017 received logging on to the standby
------------------------------------------------------------
Check that the primary and standby are using a password file
and remote_login_passwordfile is set to SHARED or EXCLUSIVE,
and that the SYS password is same in the password files.
      returning error ORA-16191
------------------------------------------------------------
remote_login_passwordfile引數配置，經查沒問題
問題估計在密碼檔案這塊，當初搭建DG時，在主備兩端透過 orapwd file=orapworcl password=oracle 生成
現將DG端密碼檔案刪掉，從生產端scp密碼檔案到DG端，問題解決
[oracle@standby dbs]$ rm -rf orapworcl
[oracle@primary dbs]$ scp orapworcl oracle@192.168.186.88:/u01/app/base/product/11.2.0/db_1/dbs/
oracle@192.168.186.88's password:
