What is AIX system ?

AIX (Advanced Interactive eXecutive) is a proprietary operating system developed by IBM for its line of Power Systems servers. It is a Unix-like operating system, based on the Open Group’s Single UNIX Specification (SUS).

AIX is designed for use in enterprise environments, and is known for its scalability, reliability, and security features. It is used by many large organizations around the world, including banks, insurance companies, and government agencies. AIX is supported on IBM’s Power Systems servers, which are based on the Power Architecture processor architecture.

What are advantages to using AIX

There are several advantages to using AIX :

Scalability: AIX is designed to scale up and support large workloads, making it suitable for use in enterprise environments.

Reliability: AIX is known for its reliability and uptime, which is important for mission-critical applications.

Security: it includes various security features, such as encryption, access controls, and secure boot, which help to protect against cyber threats.

Virtualization: AIX supports virtualization, which allows multiple virtual machines to run on a single physical server, improving resource utilization and reducing hardware costs.

Compatibility: AIX is compatible with a wide range of applications and hardware, including those developed for other Unix-like operating systems.

Support: IBM provides a range of support options for AIX, including online resources, technical support, and training.

Is AIX better than Linux ?

It is difficult to make a general statement about whether AIX is « better » than Linux, as the choice of operating system depends on the specific needs and requirements of an organization. Both AIX and Linux are robust and reliable operating systems that are widely used in enterprise environments.

One advantage of AIX is that it is designed specifically for use on IBM’s Power Systems servers, which are known for their scalability and performance. AIX also includes a range of enterprise-grade features, such as virtualization and security enhancements.

On the other hand, Linux is an open-source operating system that has a large developer community and a wide range of software and tools available. Linux is also highly customizable and can be modified to meet the specific needs of an organization.

This command will display a list of all installed software packages, along with their version, release, and other information.

You can also use the « -f » option to list the files that are included in each package:

# lslpp -l

Command correspondence on CentOS :

# rpm -qa

Delete a user :

To delete a user on an AIX system, you can use the « rmuser » command. This command will remove the user account and any files associated with the user.
