Reset AIX root password without shutting down the system
Hi All,
I'm stuck in a severe problem here , Someone have changed the root password
and he cannot remember it and there is no other user privileged user on the system , But I do have access to a non privileged user.
On the top of the system an application which requires a theoretical 24/365 availability and that application requires graceful shutdown and it's running under another user ID which the password is also lost bad luck we always do su to that to stop the application ( true laziness ) we (the unix admins guys ) cannot risk to forcelly shutdown the application .
Now I want to at least stop the application gracefully if someone have an idea to do it or reset the root password without shutting down the system.
I'm running AIX 5.3 password length 8 characters , please suggest anything else except to brute force or dictionary attack password methods I have access to HMC and sever's console also there is a VIO sever run on same server but different lpar I have access to ASMI you can say anything else except the root's password

systemd-ask-password-console.service, systemd-ask-password-console.path, systemd-ask-password-wall.service, systemd-ask-password-wall.path - Query the user for system passwords on the console and via wall SYNOPSIS
systemd-ask-password-console.service systemd-ask-password-console.path systemd-ask-password-wall.service systemd-ask-password-wall.path DESCRIPTION
systemd-ask-password-console.service is a system service that queries the user for system passwords (such as hard disk encryption keys and SSL certificate passphrases) on the console. It is intended to be used during boot to ensure proper handling of passwords necessary for boot. systemd-ask-password-wall.service is a system service that informs all logged in users for system passwords via wall(1). It is intended to be used after boot to ensure that users are properly notified. See the developer documentation[1] for more information about the system password logic. Note that these services invoke systemd-tty-ask-password-agent(1) with either the --watch --console or --watch --wall command line parameters. SEE ALSO
systemd(1), systemd-tty-ask-password-agent(1), wall(1) NOTES
