Descripción

SETROPTS PASSWORD(MINCHANGE(<nnn>) specifies the number of days that must pass between a user's password and password phrase changes. Users can not change their own passwords and password phrases within the minimum change interval. How frequently a password can be changed should be limited to prevent a user from immediately changing the password multiple times to get back to the original one.
