Oracle When sys login using tnsnames ORA-01017

事情是因為 Oracle 要與 NetBackup 對接，但 NetBackup 一直無法正常登入，因此測試了一下，發現有 ORA-01017 的錯誤

[oracle@test-db1 ~]$ sqlplus sys/oracle@test  as sysdba

正常情況用本機登看看，發現可以

[oracle@test-db1 ~]$ sqlplus / as sysdba

用 system 帳號透過 tns 登入可以

檢查了環境參數 remote_login_passwordfile 是設定 EXCLUSIVE

[oracle@test-db1 trace]$ sqlplus / as sysdba

SQL> show parameter remote_login_passwordfile

NAME				     TYPE	 VALUE
------------------------------------ ----------- ------------------------------
remote_login_passwordfile	     string	 EXCLUSIVE

檢查了 passwordfile 是否存在，發現是不存在

[oracle@test-db1 trace]$ ls -l $ORACLE_HOME/dbs/orapw*
total 0

重建 orapwfile 問題就解決

[oracle@test-db1 trace]$ orapwd file=$ORACLE_HOME/dbs/orapwtest password=oracle entries=10
