How to Answer AS400 Interview Questions
At an interview You will probably be asked questions to assess your level of knowledge about the subject you are asked about. We recommend applying the STAR method for answering these questions.


The answers to behavioral interview questions must include the word STAR which is a contraction of Situations (Statements, Tasks, Results) and actions.


What's the AS400 expansion?


The AS400 (or iSeries), designed by IBM since 1988 it is an IBM mid-range range of business computers. It has proven popular due to its reliability, scaling, security and low cost features. In addition, the system is capable of handling large amounts of data. IBM changed the name of its products and in 2006, the AS400 server changed its name to IBM System i Series.




IBM iSeries is an advanced platform that has the capacity to run a wide range of applications including ecommerce, enterprise resource management (ERP) and data warehouses. It is also used by businesses that deal with sensitive transactions, such as banking and healthcare. Additionally, its longevity makes it a great choice for businesses that require a reliable platform capable of handling massive data volumes.


The iSeries library is a hierarchical collection of directories and files, as well as different subsets. This is the primary storage area used by programs. When these programs run their output file, it is directly transferred to an output queue that remains there until it is sent directly to a printer, or deleted from the system.


You must study IBM as well as the job you applied. They look for traits like creativity, innovation and collaboration. These should be displayed in your responses in the interview process. Also, make sure to create personal stories of your successes that show those areas where your strengths are.


What are the kinds of libraries?


There are numerous libraries across the world, each with their own unique functions and purposes. Every library shares a similar mission: to provide users with information and resources.


Modern libraries are facilities that provide books as well as other materials for reading, viewing and listening to, studying or reference purposes. The librarians are educated to assist users in finding the information they need quickly. Online, libraries provide a range of services like archiving and dissemination for virtually no cost.


AS400 comprises a variety of libraries. There are a variety of libraries in AS400 that include the system library (QUSRSYS & QHLPSYS), products libraries which are automatically added and removed after job completions as well as current libraries utilized by programs during runtime, and user libraries developed by the users themselves. It is possible to view the details contained in each library by making use of commands to display the size of the library and its objects.


What is the physical source file?


The physical source file is the compilation of all source materials used to create different types of objects. as400 interview questions can have up to 32 768 members. Each source member isn't an object until it's compiled with the command CRTSRCPF.


Physical files are merely records. The format of the record can vary between them or they may share it with another physical file. These details are found in DB2 specs for RPG and RPGLE programs.


As400 library commands encompass the ones used by systems libraries, like QUSRSYS or QGPL. They also contain user libraries, like QLUB or QHLPSYS.


It is important to prepare for getting through any interview. Prepare yourself for the interview by gaining a thorough understanding of the position and being prepared to answer questions about information about software. Provide examples of previous accomplishments to show your capabilities. If you are attending your first interview at IBM make sure you do some study ahead of time to learn more about their values and culture.


What is an library command?


The AS400 computer series by IBM was developed to take care of diverse tasks associated with E-commerce, database administration, as well as enterprise resource planning. As one of most popular computing platforms, its popularity is only growing. You can expect your interviewer will ask whether you are familiar with the system. Make sure you have prepared answers that highlight your strengths and share your personal experiences of success.


AS400 has a library option that lets users quickly browse through objects and sizes of libraries. This is extremely useful in searching for members of a file in a library or viewing all members simultaneously. It's particularly helpful when working on large collections, such as QSYS System Libraries or Product Libraries, such as QHLPSYS and the QUSRSYS libraries, as well as the current libraries working on or not IBM libraries.


Using the CRTDUPOBJ to create duplicate files, order of formats for records must be in ascending or decrepit or ascending order. This is essential to join logical files which contain duplicate fields. SETGT is a way to reverse format of records order.
