How to Answer AS400 Interview questions
At an interview You will probably be questioned to gauge the level of your understanding of a given subject matter. We suggest applying the STAR method for answering these questions.


Questions for behavioral interviews should include the acronym STAR. STAR stands for Situations tasks, results, and Actions.


What is AS400's expansion?


IBM's AS400 line (or iSeries) has been in existence since the year 1988. It's a mid-range business computer, which has become popular because of its attributes like reliability, scalability, and security. The system is also capable of handling huge amounts of data. IBM changed the name of the product in 2006, and the AS400 was changed to IBM System i Series Server.



The IBM iSeries can be used to run a variety of applications, which include e-commerce, enterprise resources planning (ERP) as well as data warehouses. Additionally, businesses that handle sensitive transactions, such as healthcare and banking services frequently depend on it. Additionally, as400 interview questions makes it a perfect solution for companies that require an unbreakable platform that can handle massive volume of data.


A iSeries library is a collection of directories, files and other subsets of objects organized into hierarchies that serve as primary storage locations for applications. When these programs run, their output file is written directly to an output queue, which stays there until the file is either printed directly to a printer or deleted from the system.


You should research IBM as well as the job for which you have applied. It is important to demonstrate qualities such as innovation, creativity and collaboration in your answers to the interview. In addition, be sure to record your personal stories of your successes that show those areas where your strengths are.


What exactly is a library? what are its types?


Libraries are all over the world today, each serving their own niche, with distinct objectives and functions. Every library shares a similar purpose: to supply people with information and resources.


Modern libraries are facilities that provide books and other resources to read, watch the internet, listening to or for reference. They are staffed by librarians who will help you find the information that you need. Online, libraries offer many services, including archiving or dissemination for almost no cost.


AS400 contains several different kinds of libraries. These include the system libraries (QUSRSYS and QHLPSYS) products libraries, which are automatically removed and added upon job completion as well as current libraries that software programs utilize during runtime and user libraries that are designed by end-users themselves. You can look up the information that is contained in each library using commands that display its size and the objects.


What is the source physical file?


A physical source file holds all the materials used in the creation process for different object types. It may have up to 32,768 members; each member of the source file doesn't transform into an object until it's been compiled using the command CRTSRCPF.


Physical files are only information. Their record format may differ among them or share a file with another physical file the details are available in DB2 specifications for RPG or RPGLE applications.


As400 library commands include those that are utilized for systems libraries, like QUSRSYS or QGPL. They also include user libraries, such as QLUB or QHLPSYS.


Similar to any interview, preparation is essential for success. You should be familiar with the role and able to answer the questions of software. You should also provide the accomplishments you have made in the past that show your skills. If it is your first IBM interview, you may consider doing some background studies to gain a greater knowledge of IBM's culture and values.



What is a library command?


The AS400 computer series by IBM was designed to manage the various aspects of E-commerce, database administration, and enterprise resource planning. As one of the world's most-widely used computing platforms - seen across industries - its popularity will continue to increase. Expect your interviewer to ask you about your familiarity and levels of expertise with it. Prepare answers that show your expertise in these areas, while also sharing personal success stories related to using it effectively.


AS400's library commands allow users to look at the sizes and objects in AS400 libraries. It is possible to locate the members of a file within the collection and also view all members simultaneously. This is especially useful when working with large libraries like QSYS's system libraries, or product libraries like QUSRSYS, QHLPSYS or any current libraries that are under development.


If you utilize the CRTDUPOBJ command to duplicate files, you must be sure to sort the formats of records in ascending up-and-down order. In other words, records that are not the same will be skipped. SETGT can be used to reverse the record format order.
