密碼檔案導致Data Guard同步錯誤：error 12514，Error 1033 - 1

Linux 6.5 ， Oracle 11.2.0.4 

按照建立Data Guard的文件建立資料庫standby後，發現同步總是報錯， 如下是主庫的alert log ,  透過主庫上設定的tnsnames.ora中的備庫別名，發現連線沒有問題，
sqlplus /nolog
conn   sys/xxxxx@em12cdg  as  sysdba 
....

同樣驗證了主庫備庫中的sys密碼一樣。 但是備庫中的 orapwSID 密碼檔案是透過orapwd命令生成的(不是從主庫複製過來的)，雖然密碼相同，但是奇怪的是，大小不一樣，
一個1536 Bytes (主庫)， 一個2048 Bytes(備庫)， 懷疑是不是密碼檔案的問題， 關閉備庫後重新複製主庫上的orapwem12c 到備庫， 開啟備庫到managed standby狀態，結
果可以正常同步了。 


主庫報錯資訊如下：
