    Hello everyone

    I tried to create a profile to visit below but got an error:

    Password_Lifetime 7

    Function search function password_verify;

    password_verify-function Verification function

    ERROR in episode 11:

    I removed the d password_verify_function and it worked:

    Profile created.

    Now I tried to reset the Verify+ function, but I also found errors:

    SQL> /
    Edit app_user

    ERROR on line 1:

    How do I create a profile with all the settings I need, especially the password_verify_function?

    The hyphen must be a characterol underscore. And you know what happens after it’s actually a working name (you have so many typos that I can’t tell if you’re entering invalid commands or just typos). By default, I don’t think the verify_function is the last one in the database. Ask your current DBA. It is in utlpwdmg script.sql

    . Oracle can use this setting to enable this password strength.

    Now, in order to implement this password checking function, you must first create a function in the SYS schema.
