oracle password in version 11.2
I am looking at the password data for oracle IDs in a database that was just upgraded from 10.2.0.4 to 11.2.0.3 and here is what I see
SQL> select name, spare4 from user$ where name in ('TEST1','OUTLN');
NAME SPARE4
------------------------------ --------------------------------------------------
OUTLN
TEST1 S:XXX
SQL> select username, password , password_versions from dba_users where username in ('TEST1','OUTLN');
USERNAME PASSWORD PASSWORD
------------------------------ ------------------------------ --------
OUTLN 10G
TEST1 10G 11G
TEST1 is an ID that I have created after the upgrade. So the password value is stored in the spare4 column in user$ table. OUTLN is an ID that was creaed under v10 version so I expected to see the value in the password column of the dba_users table, but that column is empty. Is that how it is supposed to look like or am I missing something? Would appreciate any thoughts
