SQL> 

remote_login_passwordfile 参数为exclusive(启用口令文件，允许远程登录)

SQL> show parameter remote_login_passwordfile

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

查看密码文件:

SQL> select * from  V$PWFILE_USERS;

no rows selected

说明密码文件没有设成功,设密码文件:

orapwd file=orapwLU8DB entries=10 password=1254878@1020 force=y　　--注意ORACLE_SID 是大写的,否则不成功

再次查看密码文件:这时有内容了,再次远程用SYS 登录,成功
