    You can also modify the password file status. Password file status information stored in the document, when it is created, its default state of SHARED. By changing the initialization parameter can be set to change the password file REMOTE_LOGIN_PASSWORDFILE state. When you start the database instances when, Oracle systems from the initialization parameter file to read REMOTE_LOGIN_PASSWORDFILE parameter settings; when loading the database, the system password file this parameter and to compare the state, if different, then update the password file status. Best of luck.
