RE: password iin dba_users - Oracle 11

I saw that on my system Jared and didn't really understand it but I am sure I 
have head or read something that it is to do with migrating users.
I am happy to be corrected on the matter by anybody who knows better than me 
(which won't be that difficult)

John

Jared,

I understood that the old style password hash was there to support a database 
which has been migrated from 10g to 11g and converted to use the new case 
sensitive passwords.

As an ex 10g user changes his password or has an alter user command run against 
him he changes from the old hash to the new hash (which also includes case 
sensitivity) which is the reason why there is room to accommodate both hash 
versions.

I don't claim to know exactly why the hash and sha1 passwords are both included 
in
sys.user$, but that doesn't seem to fit the bill.

on an 11.1.0.7 database

SQL> create user scott identified by tiger

SQL >select name, password, spare4
from sys.user$
where type#=1
and name = 'SCOTT';

NAME            PASSWORD             SPARE4
--------------- -------------------- 
--------------------------------------------------------------------------------
SCOTT           F894844C34402B67
