In an interview, you will likely be asked questions that will test your level of understanding about the topic you're asked to discuss. To ensure a positive response, we recommend the STAR Method.
Answering behavioral interview questions should include the word STAR which is a contraction of Situations and Tasks, Results and actions.
What's the expansion of AS400?
IBM's AS400 line (or iSeries) has been present since 1988. It's a mid-range business computer, which has become famous due to its characteristics like reliability, scalability and security. The system is also able to handle massive amounts of data. IBM changed the designation of the product in 2006, and the AS400 was changed to IBM System i Series Server.
IBM iSeries is an advanced platform that has the capacity to be used to run a variety of programs including ecommerce, enterprise resource management (ERP) and data warehouses. Additionally, businesses that handle sensitive transactions such as healthcare and banking frequently depend on it. Furthermore, as400 interview questions makes it a perfect solution for companies needing an infallible platform that is capable of handling huge quantities of data.
An iSeries library is an object collection of directories, files and other subsets of objects arranged into hierarchies that serve as the primary storage location for programs. As these programs run their output files, they are stored directly in an output queue. It remains there until it is sent directly to a printer, or removed out of the system.
In your interview preparation it's crucial to conduct a thorough research of IBM and the job you to apply. They are looking for qualities such as innovation, creativity, and collaboration which should be displayed in your responses during an interview. You should also be prepared to share your own personal success stories that highlight these areas.
What is a library and what types are there?
Libraries are found all over the world. Each has its own purpose and function. Libraries offer access to resources and data.
Modern libraries have audiobooks, videobooks, books and other items that can be used for studying, reading, or listening. Staffed by trained librarians ready to help users find the items they require fast. Libraries offer a wide range of services like the archiving of information and dissemination for a minimal cost.
AS400 contains several different kinds of libraries. These include the system libraries (QUSRSYS and QHLPSYS), product libraries that are automatically added and removed after the job is completed, current libraries that programs use during runtime and user libraries built by users themselves. There are commands that allow you to look up information such as size or objects inside the library.
What is a physical source file?
The source physical file is the collection of all the raw materials utilized to make different kinds of objects. It may contain up to 32 768 members. Every member isn't an object until it's compiled with the command CRTSRCPF.
Physical files are just information. The format of their records could differ among them or share one with another physical file - this information is available in DB2 specifications for RPG or RPGLE programs.
AS400 library commands comprise those for system libraries such as QUSRSYS and QGPL and product libraries such as IBM product libraries, user libraries such as QLUB or QHLPSYS; LCD to change local system directory; GET to retrieve library/source physical member from source physical file members list; and REPLACE for transferring information directly to software or other physical file locations.
As with every interview, preparation is the key to a successful interview. Prepare yourself for your interview by gaining a thorough understanding of the job and preparing to answer any questions related to software knowledge. Offer examples of past achievements to demonstrate your abilities. If you're going to be attending your first interview at IBM make sure you do some study beforehand to better understand their culture and values.
What is the library command?
IBM created the AS400 computer in order to tackle the many tasks associated with ecommerce, database management, and enterprise resource planning. As one of most popular computing platforms it is growing. You can expect your interviewer to ask you about your knowledge and levels of expertise with it. Prepare answers that highlight your strengths in these areas as well as sharing your personal stories of success working with it effectively.
AS400's library command lets users to view the sizes and types of objects that are in AS400 libraries. It is able to locate the members of a file within a collection as well as see all members at once. This is particularly helpful for large collections like QSYS system libraries or product libraries such as QHLPSYS, QUSRSYS or libraries currently under development.
When using the CRTDUPOBJ command to duplicate files formats should be ordered in ascending order for join the logical files that have fields that are duplicates; otherwise, records in one file which don't align with the secondary counterpart will be removed from the file. SETGT is a way to reverse record format order.
