Oracle：DG error ORA-16191錯誤

告警日誌出現大量的：
[oracle@primary trace]$ tail -f alert_orcl.log
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

看到這樣的告警，感受是主備庫的sys密碼不一致致使的，因此：
當初搭建DG時，在主備兩端經過 orapwd file=orapworcl password=oracle 生成
現將DG端密碼文件刪掉，從生產端scp密碼文件到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:
orapworcl 100% 1536 1.5KB/s 00:00
