264.-How To Password file Oracle / advanced orapwd utility
1. Create the password file. This is done by executing the following command
$ orapwd file=filename password=password entries=max_users
2. Edit the init.ora parameter remote_login_passwordfile. This parameter must be set to either
SHARED or EXCLUSIVE. When set to SHARED, the password file can be used by multiple databases,
yet only the SYS user is recognized. When set to EXCLUSIVE, the file can be used by only one
database, yet multiple users can exist in the file. The parameter setting can be confirmed by:
SQL> show parameter password
NAME TYPE VALUE
----------------------------- ----------- ----------
remote_login_passwordfile string EXCLUSIVE
3. Grant SYSDBA or SYSOPER to users. When SYSDBA or SYSOPER privileges are granted to a user,
that user's name and privilege information are added to the password file.
SQL> grant sysdba to scott ; Grant succeeded.
4. Confirm that the user is listed in the password file.
SQL> select * from v$pwfile_users;
USERNAME SYSDBA SYSOPER
------------------------------ ------ -------
SYS TRUE TRUE
SCOTT TRUE FALSE
Now the user SCOTT can connect as SYSDBA. Administrative users can be connected and
authenticated to a local or remote database by using the SQL*Plus connect command. They must
connect using their username and password, and with the AS SYSDBA or AS SYSOPER clause:
SQL> connect scott/tiger as sysdba;
Connected.
The password file creation utility evaluates the new parameter ignorecase to allow case-sensitive
passwords or restrict passwords to case insensitivity. In order to create a password file with
orapwd, which allows case-sensitive passwords, set ignorecase to N.
[oracle@rhas4 ~]$ orapwd help=y
Usage: orapwd file=<fname> password=<password> entries=<users> force=<y/n>
ignorecase=<y/n> nosysdba=<y/n>
