作用：  指定Oracle是否检查密码文件。
REMOTE_LOGIN_PASSWORDFILE    specifies whether Oracle checks for a password file.


Values:

shared

One or more databases can use the password file. The password file can contain SYS as well as non-SYS users.


exclusive:

The password file can be used by only one database. The password file can contain SYS as well as non-SYS users.


none:

Oracle ignores any password file. Therefore, privileged users must be authenticated by the operating system.


Notes:

When REMOTE_LOGIN_PASSWORDFILE is set to either exclusive or shared, but the password file does not exist, 

then the behavior is the same as setting REMOTE_LOGIN_PASSWORDFILE to none.



If you change REMOTE_LOGIN_PASSWORDFILE to exclusive or shared from none, 
then ensure that the password file is in sync with the dictionary passwords.
