How to change password expiration in Oracle 11g


Another quick hint, this time for Oracle database administration.

Starting Oracle 11g the default profile that users belong to, if no other profile is specified, forces the password to be changed within 180 days. Previous versions didn’t have this “feature”, so this might result in a nice surprise when you find out that your application isn’t working anymore after 6 months.

Although security-wise it’s a good idea to change passwords now and then, sometimes it’s necessary for the password to remain the same. To change the expiration time to unlimited for the default profile, execute the following statement:

alter profile default limit password_life_time unlimited;
