you can finish it by following COMMAND

c:\>orapwd file=%oracle_home%\database\pwd%oracle_sid%.ora password=yournewpassword entries=5


usage:
C:\Documents and Settings\xl>orapwd
Usage: orapwd file=<fname> password=<password> entries=<users>

where
file - name of password file (mand),
password - password for SYS (mand),
entries - maximum number of distinct DBA and OPERs (opt),
There are no spaces around the equal-to (=) character.

C:\Documents and Settings\xl>

Remember first you have to rename or delete the current password file.
Otherwise it will not allow you to create new password file.

hi.....
just see the following step to create carsh because of password file and then how to recover it...


RECOVERY OF PASSWORD FILE
-------------------------
If in any case password file gets corrupted (i.e. deleted) then we have to generate password file.

Generating crash

[1] Shutdown

[2] Rename PASSWORD FILE or delete it.

[3] Go to DOS.
Start sqlplus sys as sysdba/password.

[4] Startup Database
Database does not start and gives following error :

ERROR at line 1:
ORA-01990: error opening password file 'E:\oracle\ora90\DATABASE\PWDora9i.ORA'
ORA-27041: unable to open file
OSD-04002: unable to open file
O/S-Error: (OS 2) The system cannot find the file specified.

[5] Shutdown

GENERATING PASSWORD FILE

[6] Create PASSWORD FILE

C:\ > ORAPWD FILE=e:\oracle\ora90\database\PWDora9i.ora password=oracle
entries=5

--“ORAPWD” is the utility to create password file
--password file we are creating must have extension as “.ORA”
--“ENTRIES” means how many users can be added to password file
