AIX 5L is an IBM 64-bit UNIX version with strong Linux bias. Specifically for applications, database, and transaction services designed AIX 5L ("L" for Linux) is a versatile server operating system that provides the ability to work together between 32 and 64-bit applications by sharing this performance between file access, memory, and different system services.
The AIX
In single-user mode, AIX resets the password when the password of the root user is lost. This is troublesome and requires you to restart the machine. For security, the password of the root user must be properly configured and kept.
