Oracle Password Complexity Configuration
I want to configured password complexity on oracle database level like,
The password has a minimum length.
The password is not the same as the username.
The password has at least one alpha, one numeric, and one punctuation mark character.
The password is not a simple or obvious word, such as welcome, account, database, or user.
The password differs from the previous password by at least 3 characters.
Could you please someone let me know that where should I configured these setting means which configuration file.
I also found on the internet that the Oracle's password complexity verification routine can be specified using a PL/SQL script (UTLPWDMG.SQL). Is this file where I set the parameters as per the requirement or should I use init_<sid>.ora file.
Thanks in advance.
