Hi,

First, I am new to Oracle DB. I have a Vista and installed Oracle 10G. I also installed the sample schemas. After installation, i tried to use scott account. I was able to unlock the account using this command

alter user scott unlock;

however, upon checking, it shows that scott password expired and tried this command:

ALTER USER SCOTT IDENTIFIED BY newpassword;

but i'm getting this error:

C:\OraHome_1\RDBMS\ADMIN>sqlplus /nolog

Rem DESCRIPTION
Rem This is a script for enabling the password management features
Rem by setting the default password resource limits.
Rem
Rem NOTES
Rem This file contains a function for minimum checking of password
Rem complexity. This is more of a sample function that the customer
Rem can use to develop the function for actual complexity checks that the
Rem customer wants to make on the new password.

-- This script sets the default password resource parameters

Your password contains characters and digits but no punctuation
