AS400 Software for Security Access Controls

It is vital to protect exit point access to the AS400, DB2 database file, and instructions in environments where sensitive data is stored. It is necessary to audit and protect the AS400 since it has several access pathways that must be checked for various internal and external access vulnerabilities and threats as well as adherence to regulatory compliance standards. To ensure that your security policies are being followed, we provide a variety of AS400 security tools such as exit programs to secure AS400 exit point access.

We also provide industry leading reporting technologies to satisfy auditors as well as event log forwarding and integration tools for SIEM and ticketing systems.

Encryption, Masking, Scrambling and Tokenization

When dealing with sensitive data in an AS400 DB2 database file, it is recommended that the file be encrypted or that a comparable data protection technique be used to conceal or obscure the actual contents. Protecting sensitive data at rest using AS400 encryption using the AES256 algorithm is the safest and most widely acknowledged security method available. We offer a comprehensive set of data security technologies to secure your AS400 database if you have variables or other situations that prevent some DB2 fields from being encrypted and a compensating control for masking, scrambling, or tokenization has been authorized.

The encryption software contains a key management system and is compatible with third-party key management systems that are OASIS KMIP-compliant.

Auditing, SIEM and Ticket System Integration Software

AS400 systems have a plethora of event log sources that contain information about security and operational events, as well as performance, performance monitoring, and application events. This information can be used to identify and isolate critical incidents, which can then be fed into your company’s SIEM or Ticketing System. To facilitate interaction with important infrastructure tools, our AS400 software is capable of automatically formatting and forwarding event logs in real-time from the following log sources: Commands, SQL Statements, Message Queues (history, subsystems, traces), Socket Exit Programs (secured ports), Privilege Access Management (profile swap, adopted authorities, and other elevated authority events), MFA, and Static data (user profile, system values, authorities, objects and other static data) are all examples of information that can be found in the QAUDJRN and QHST security journals (HTTP, 3rd party applications) We can integrate with any SIEM, SYSLOG Server, Ticketing System, or other monitoring solutions that can handle and ingest the event log types listed below.

JavaScript Object Notation (JSON), Log Event Extended Format (LEEF), Common Event Format (CEF), LogRhythm SIEM (LOGR), Generic Message Format (GENR), User Defined Format (USRD), SYSLOG Message Format, Log Event Extended Format (LEEF), Log Event Extended Format (LEEF), Common Event Format (CEF), LogRhythm SIEM (LOGR), Generic Message Format (GENR), User Defined Format (USRD), SYSLOG Message Format (RFC5424).

The following third-party plug-and-play AS400 integrations are available: Splunk, QRadar, LogRhythm, DataDog (formerly DataDog), ArcSight (formerly SolarWinds), AlienVault (formerly Exabeam), ServiceNow Discovery (formerly ServiceNow Discovery), and other tools used for security and operations monitoring that use certified APIs or supported formats to enable immediate integration to display dashboards, run reports, and trigger alerts.

Database Replication, Conversion, Migration and ETL Projects

In addition to converting data across practically any database format and multiple operating systems and hardware platforms, our database replication solutions maintain the dissimilar databases synced in real time and without locking either the source or destination database files. Insert, update, and delete operations on the distant target database are handled by our database replication software just like any other insert, update, and delete transaction. For long-term analytics, reporting, and ETL efforts, as well as one-time conversion initiatives to move to a new database platform, duplicating a production database to a different database type has several applications.

Our database replication and conversion software allows programs and users to access and change both the production and target database files without causing any interruptions in their operations.

Disaster Recovery and High Availability Software

The high dependability of the AS400 should not be used as a justification for businesses failing to take the essential safeguards to develop a business continuity strategy. A company’s bottom line will surely benefit from ensuring that mission important applications stay online in the case of scheduled and unforeseen downtime events. Unplanned disasters are not always the most expensive or even the most prevalent type of total cost of ownership calculation. On an AS400 system, the availability events that cause the biggest disruptions and have the most impact on business continuity are nearly always tied to scheduled downtime events.

The latest Global Server Hardware Server OS Reliability data reveal that the IBM Power system platform had an average of only 1.54 minutes of unexpected downtime per server as a result of faults in IBM hardware during the period under review.


System I often known as the AS/400, was a database machine designed by IBM that was a continuation of the System/38 architecture (announced by IBM in October 1978 and delivered in August 1979). The AS/400 was the first system to do away with capability-based addressing. The AS/400 enhanced source compatibility with the System/36, bringing together the two principal computers made by the IBM Rochester factory in one system. System/36 was IBM’s most successful minicomputer, although the design had reached its limits by this time.

  • Silverlake was beta-tested by Guy Dehond of Inventive Designers, who was also one of the beta-testers.
  • Dr.
  • The AS/400 was one of the first general-purpose computer systems to get a C2 security rating by the National Security Agency (the Gould UTX/C2, a UNIX-based system, was designated in 1986), and it was upgraded in 1995 to include a 64-bit CPU and operating system (the AS/400-64).
  • This created difficulties for people who purchased third-party items that were devoid of a source and were therefore unobservable.
  • It was in 2004 that IBM introduced the i5 servers, which were the first to employ the IBM POWER5 CPU.
  • When 128-bit processors become available, the system’s design will allow for the installation of those processors in the future.
  • Since the advent of Lou Gerstner as CEO in 1993, IBM has deemed such massive internal advances to be too dangerous to proceed with them.
  • It is worth noting that, following the resignation of CEO John Akers in 1993, when IBM appeared to be on the verge of being broken up, Bill Gates stated that the only part of IBM that Microsoft would be interested in purchasing was the AS/400 business.

As of that time, many of Microsoft’s business and financial systems ran on the AS/400 platform, which was no longer the case after the release of Windows 2000 in 1999.)

Logical PARtitioning

Multiple operating systems may be operated on one IBM System I unit thanks to LPAR (Logical PARtitioning), a technology that was first developed for mainframe computers and brought to the IBM System i. A system designed with LPAR allows users to run many operating systems on distinct partitions while guaranteeing that no one operating system takes up more memory or resources than is necessary. Through the use of a weighting mechanism, each LPAR is assigned a fraction of system resources (memory, hard disk space, and CPU time), which dictates where unused resources are allocated at any particular moment.

Others include an integrated DB2 database management system, a menu-driven interface, multi-user support, nonprogrammable terminals (IBM 5250) and printers, security and communications capabilities, and support for client–server and web-based applications, among other things. The IBM System I operating system includes a large amount of software that is required to run the system. This software is incorporated within the operating system.

Common Client-Server Support

In addition, standard client–server systems such as ODBC and JDBC are supported by the IBM System I for accessing its database via client applications such as Java, Microsoft.NET languages, and other programming languages.

AS400 Programming

The AS/400 supports a number of programming languages, including RPG, assembly language, C, C++, Pascal, Java, EGL, Perl, Smalltalk, COBOL, SQL, BASIC, PHP, PL/I, Python, and REXX, to name a few. CASE tools are available in a variety of flavors, including CA Plex (previously AllFusion Plex), Synon, the IBM Rational Business Developer Extension, Accelerator, the LANSA Framework, Uniface, and GeneXus.

Integrated Language Environment

With the ILE (Integrated Language Environment) programming environment, it is possible to combine programs written in ILE compatible languages (such as C, C++, COBOL, RPG, Fortran, and CL) into a single executable and call procedures written in any of the other ILE languages at the same time. The Java programming language, as well as 32- and 64-bit Java Virtual Machines, is fully supported by the IBM System i. (JVM). Commands in the Control Language (CL) can be prompted by pressing the F4 function key on the keyboard, and the majority of them feature cursor-sensitive assistance to make setting command arguments easier to understand.

If you want to apply a text description to any object that is being created or updated, for example, the parameter keyword is spelt the same way for all of these actions. Examples:

  • Users’ profiles can be created, shown, changed, and deleted using the CRTUSRPRF, DSPUSRPRF, CHGUSRPRF, and DLTUSRPRF commands. CRTLIB, DSPLIB, CHGLIB, and DLTLIB are all libraries that may be created, shown, changed, and deleted. ADDLIBLE, RMVLIBLE, CHGLIBL – Add or remove entries from a library list, or alter the library list. A file may be copied and modified with the help of the CPYF, the CRTF, the DSPF and the CHGF.

Instead of batch processing with little or no user interaction, display files are used to support 5250 display operations. Display files serve as an interface between workstations, keyboards, and displays, and interactive applications, as opposed to batch processing with little or no user interaction. ASCII terminals and PC workstations are equally and well supported, as is connectivity to the internet or a local area network (LAN), which may be enhanced by IBM or non-IBM communication software, such as TELNET or TELNET 5250, for example.

The ability to create, maintain, and access record-oriented files on distant IBM mainframe systems running CICS enabled applications to communicate with remote System/36, System/38, and System/38-based mainframe systems. This support was expanded to include the AS/400 and its subsequent releases. It was improved in order to enable more services that had been established by DDM as well as AS/400-specific extensions that had been permitted by the DDM.

Is the IBM AS/400 software dead?

Many information technology experts still refer to the AS/400 as “AS/400.” There are examples of this in job titles, professional affiliations, and certificates. It has been included into the internet information we consume as well as the items we use on a daily basis. Despite this, the question “Is the AS/400 dead?” is a popular one voiced among the AS/400 user community. The question current users, job seekers, and companies are asking themselves is whether a platform that was first offered in 1988 is still relevant today.

  • The IBM AS/400 system was first presented in 1988.
  • Both the hardware and the software have undergone several updates, modifications, and renamings during the course of its existence.
  • One of the most distinguishing characteristics of this platform has been its upward compatibility since its inception.
  • A major reason why many firms that acquired an AS/400 years ago continue to refer to it as an AS/400 even though their Power server is orders of magnitude faster and incorporates cutting-edge capabilities is because of this seamless compatibility.

Every two to three years, they release new versions of the hardware and software, which represent quantum leaps forward in terms of processing power and usefulness compared to previous generations.

Why is AS/400 Still Used? 4 Reasons to Stick with a Classic

Since the 1980s, IBM Power Systems computers have been a cornerstone of business information technology. Their performance, stability, and dependability have been well regarded since the introduction of the AS/400 and on to the present IBM iSeries. However, as business cloud services have proceeded to supplant onsite ERP, some have written off the AS/400 as a result of this trend. With the ever-decreasing cost of cloud hosting, the IBM AS/400 is being depicted as an antiquated, expensive relic from a bygone era by its critics.

The critiques, on the other hand, are overblown, and there are valid reasons why so many businesses continue to rely on the IBM AS/400.

Companies That Use AS/400

AS/400 servers are still in widespread use today. IDatalabs estimates that IBM hardware is utilized by around 10.1 percent of firms who have their own servers, making it the second most common type of server behind HP servers (24.7 percent ). But those statistics are a bit misleading since they are based on hardware rather than operating system, and because cloud hosting services are counted in a different category from other types of computing. Only one percent of organizations use the IBM ioperating system, and only 0.7 percent use the AIX operating system, according to iDatalabs’ analysis of the two operating systems most closely linked with the IBM hardware.

In high-tech areas like as manufacturing, computer software development, and information technology, the AS/400 is widely used.

The AS/400 operating system is most common among midmarket enterprises (38 percent), but it is utilized by businesses of all sizes.

In 2016, the firm earned around $88 billion in worldwide revenue from the production of a diverse variety of consumer items, industrial technologies, and other products.

Bosch, being a huge corporation, manages its own internal IT, which oversees more than 900 SAP implementations worldwide. They chose IBM Power8 servers to operate its information technology systems because of their high performance, dependability, and scalability.

What is AS/400 Used For?

The AS/400 architecture is frequently used for enterprise resource planning (ERP) and other mission-critical activities, particularly in industries that demand high levels of reliability, such as the manufacturing industry. The IBM Power Systems database management system is popular among users of SAP as well as users of rival database management systems such as Oracle Database. With the rise of the AS/400 cloud, the IBM architecture has also become a more and more popular cloud-based option for businesses.

The AS/400 platform is capable of hosting virtually anything at this time, although various use cases may necessitate quite different deployment strategies.

Why is AS/400 still used?

  1. IBM Power Systems maintain the famed performance and dependability of the AS/400 system. A large amount of hardware redundancy was included in the design of the IBM AS/400, which was intended to be bulletproof — particularly at the top of the server range. It’s also exceptionally high-performing, thanks to CPUs that are 3-5 times more powerful than those used by its competitors. These characteristics are appropriate for applications like as SAP hosting, which demand exceptionally high performance and little downtime. There is a wide variety of AS/400 configurations available for purchase. A wide range of products are available, ranging from affordable entry-level systems to high-performance, massively redundant servers for larger business users, as well as scalable versions for ever-expanding data centers. The IBM iSeries is also capable of running a variety of operating systems, including AIX, IBM I SUSE, and RedHat Enterprise Linux
  2. However, moving away from IBM Power Systems is not a wise investment of time or money. Although IBM Power Systems are more expensive per core than their competitors, their cores are also far more powerful. During a recent presentation, IBM demonstrated a price/performance advantage for Power Systems LC machines versus Intel Proliant machines in both single and twin socket configurations, respectively. Keep in mind that this is a test conducted by IBM, and that there are no exact statistics for performance because it is dependent on the architecture and workload. To be sure, this demonstrates that the IBM AS/400 is priced comparable to its competitors, at the very least. Any cost savings realized by switching hardware will be overshadowed by the expenditure and inconvenience incurred by transitioning to a different platform — particularly in light of the availability of cloud-based solutions. Additional benefits include backward compatibility, which may significantly minimize the cost of transitioning from one system to another. In particular, this is true for businesses that may be relying on legacy software or bespoke code that is built on the AS/400 platform. Moving away from the AS/400 may entail the installation and configuration of new software and the audit and updating of existing data. This is a significant undertaking when you’ve been using the same platform for decades. When you’re a manufacturer with an old control system design, this may also be incredibly disruptive to your operations. In these cases, switching away from IBM is a waste of money that serves no purpose
  3. The AS/400 managed cloud, on the other hand, provides a comprehensive answer. As a result of our IBM iSeries cloud environment, the AS/400 has emerged as a really competitive alternative for the cloud age.” We lower your total cost of ownership by replacing uncertain CapEx with predictable OpEx, charging only for the resources you really use.

Is AS400 an ERP System

IBM AS400 ERP Software, its history, benefits, differences, checklist, and challenges will be discussed in this section. Next Generation Cloud-basedXimple ERP Software will be shown. AS400 Software for Enterprise Resource Planning

What is AS400 Software?

IBM’s AS400 Software is a mid-range server with a lot of features. The AS400 iSeries, which was first introduced in 1988, is a cornerstone product that more than one hundred thousand enterprises rely on today. Despite the fact that the AS400 Software System is not the most sophisticated software available today, it meets the demands of a variety of enterprises. Don’t be alarmed if you come across terms such as IBMi, iSeries, or System I that seem similar. All of them are referring to the same thing.

The operating system, originally known as OS400, has undergone several rebrandings throughout the years.

It combines an interactive AS400 System database with networking, security, internet services, and storage management capabilities to provide a comprehensive solution for the business world.

What is IBM As400 ERP? – History, Benefits and Challenges

The AS400 was created by IBM around 33 years ago. System had both hardware and an operating system, and it was marketed as an integrated offering (software). The hardware was an AS400, and the operating system was OS400. In order to maintain its mid-range product line competitive, IBM has made several upgrades to both the hardware and software throughout the years. Their product was likewise brand new, having been rebranded to better match it with the market and their offering. Currently, the hardware is referred to as Power Systems, and it operates on an improved operating system known as IBM i.

It is compatible with a variety of programs, including as400 inventory management and accounting software despite the fact that it is almost a decade old.

Despite the widespread belief that the system is out of date, numerous businesses continue to rely on it because of its seamless interoperability.

Every two to three years, IBM refreshes and enhances its platform, which is a standard practice for the company. The following is a brief overview of its history:


The AS400 system line is compatible with the OS/400 operating system. Everything that was written for System/34 and System/36 might potentially be ported to the new AS400 platform. System/34 and System/36 were part of the company’s initial series of minicomputers, which comprised the System/3 and System/32, which were introduced in 1979.


The IBM AS400 System was rebranded to the iSeries.


The IBM AS400 System was renamed to the iSeries system in 2003.


Earlier this year, IBM unified the System I and System P product lines and labeled the resulting product offering as IBM power system

Benefits of AS400 ERP

Despite the fact that it is a computer server that was created many years ago, the iSeries computer is still operational. It provides the following advantages:

  • Affordability– Your company may start with the most economical core server and then upgrade to a more powerful 256-core server. The AS400 is the most reliable server available if you are searching for a server that can provide close to 100 percent uptime. Safe– As long as you have your IBMi configured correctly, it will operate in a safe manner. A sophisticated server, because it is continuously updated, it has grown more current and supports a wide range of programming languages, including RPG and Java, among others
  • It is also more secure. Compatibility– As previously said, System I provides exceptional compatibility, allowing for more seamless transitions.


Despite being equipped with cutting-edge technology, the i5 system faces a number of difficulties:

No IBM AS400 is not enterprise resource planning software, despite the fact that many beginner users refer to it as AS400 Enterprise Resource Planning Software. Consider AS400 to be an operating system that is on par with Microsoft Windows or Linux in terms of performance. What distinguishes AS400 from other operating systems is that everything in AS400 is specified as an object, whereas other operating systems have files. Instead of recognizing hardware and software things as objects, Windows and Linux treat them as files.

This platform supports a large number of mission-critical corporate applications and enterprise resource planning systems.

What’s different between legacy Software vs Next Generation of ERP

ERPs that are not online are known as legacy software systems. It is for this reason that they are referred to as on-premise ERP systems. The next generation of ERP, on the other hand, refers to enterprise Resource Planning solutions that are hosted in the cloud. When contrasting the two, it is necessary to distinguish the differences. These are the ones:

  • The main distinction between Legacy ERP and Cloud ERP is that the latter provides more accessibility. When it comes to legacy ERP systems, you, as the owner, are required to lease and maintain them on your desktops or servers. As a result, anyone who is permitted to use them will only be able to access them on your computers. Next-generation ERPs, on the other hand, are stored on an internet server that you either own or lease on a monthly basis. To access the system, just web browsers like as Safari, Chrome, and Edge are required
  • Next Generation ERPs are built on a foundation that will last for years to come. Future technologies such as the Internet of Things (IoT), machine learning, artificial intelligence, big data analytics, and cloud computing will be supported by its open design. ERP offers basic features that are highly specific to the particular sectors that it serves. Such enterprise resource planning systems are SaaS-based, often known as Software as a Service. It simply implies that you must pay a membership fee in order to be granted access to use the software and hardware on which it is based. Because it is structured as a series of monthly payments, your company will suffer operational expenses. Legacy ERP systems, on the other hand, are the property of the firm that maintains them. Both the software and hardware components must be purchased in advance, granting the purchaser complete ownership of both. In this case, software development consulting businesses might be of assistance. They are less expensive than employing a team of in-house IT professionals who are paid on a monthly basis
  • Cloud-based next generation ERP systems are simpler to adapt and upgrade. The user has the ability to make adjustments automatically. The other side, on-premise legacy ERP systems are tough to modify and upgrade unless your IT crew is well-versed in the process. Using a freelance software development consultant is a good idea if you don’t have a solid information technology workforce. Because all that is required to access a modern generation ERP system is a web browser, any internet-enabled device may be used to do so. Legacy ERP, on the other hand, can only be accessed through a computer at your workplace.

What’s ERP upgrade processes Checklist?

  • Come up with a strategy to assist you in completing the software upgrade
  • Preparation of a selection of ERP specialists that can assist you The finances, track record, and capacity to produce on schedule are all important considerations when selecting a consultant. Organize a group of people to supervise the upgrading process. This team will serve as a liaison between your company and the consulting firm that you have picked. With the support of your consultant, put into action the strategy you developed in the first phase.

What are ERP upgrade benefits?

If you are still using a legacy ERP system, it is critical that you modernize it in order to reap the benefits that others who utilize cloud-based next generation ERP systems enjoy. It is critical to upgrade to the most recent version in order to receive frequent software updates, new features, service packs, and other key features in real time. A system that has been upgraded will run properly and decrease the amount of downtime experienced by your employees. An improved system increases the speed with which everyday duties are completed and ensures compliance with government laws such as ISO, HIPPA, ACA, and IFRS, among others.

As you transition away from IBM AS400 ERP and toward Cloud-based ERP, it’s critical to minimize any business interruptions. AS400 Enterprise Resource Planning

Why Major Distributors are migrating AS400 ERP to Cloud ERP

These organizations have recognized that the AS400 ERP system is an excellent system, but it suffers from the legacy syndrome. Once you have it you will only access it on your in-house PCs or servers. It is more difficult to update while on the go, as opposed to the most recent IBM iSeries version on the web. That is why the majority of businesses are looking to replace their AS400 ERP systems to Cloud ERP systems. When it comes to combining the greatest features of System I with those of contemporary software, a smart consultant knows how to do it.

What’s the benefits of APIs, microservices, Java and Angular Technology AS400 ERP?

There are two types of architectures used in software consulting and development. Microservices are one type of architecture, whereas monolithic architecture is another. The former is preferred due to the fact that it is more contemporary. A single large application is divided into a number of small modular services using this design strategy. When every tiny modular service contributes to the achievement of a specific business goal, agility and scalability are possible. A single piece of code can be reused for several implementations.

When migrating from an on-premises ERP system to a cloud-based ERP system, microservices will make the integration process much more smooth.

They are simple to read, which is important when working with complicated systems, and the Java EE standards are compatible with microservices applications, such as JAX-RS for RESTful APIs.

How ERP Consultants can facilitateeasy ERP migration

  • Initially, consultants will assess the present state of your ERP systems in order to establish where your historical ERP requirements have changed. Find strategies to make the transition as seamless as possible while keeping your company’s objectives and goals in mind. Technological executives are faced with a difficult decision: should they update to a new version of existing ERP software or should they move to a new ERP? If you want to lay the groundwork for years to come, then moving to modern Cloud-ERP is a better option than staying with traditional ERP. Plan ahead of time to ensure that disruptions are kept to a minimum. If the migration process is to be successful, it must be comprehensive and uninterrupted. Take precautions to avoid the possibility of causing mistakes or losing data during the transfer process. It is essential to establish excellent working relationships with consultants and ERP vendors. Customer-centricity is required on the side of both partners in order to provide world-class service during and after the ERP transformation.

Published on February 26th, 2020 The most recent update was made on March 13, 2020. How many programmers/developers are there in your immediate vicinity that are familiar with or interested in learning about AS400? Perhaps only a small number, or perhaps none at all. Although the AS400 is regarded to be extinct, the newest IBM Power systems with IBM I are still considered to be one of the most resilient and stable system designs, and are still in use by many enterprises. Despite the fact that it is a legacy system, its updated versions feature a strong operating system and documentation.

AS400-Why and What?

IBM introduced the AS400 computer series, which was designed to be simple to use for small companies and corporations. When compared to other computer systems of the 1980s, this mid-range computer series provided superior performance and more data security than their counterparts.

A brief history…

The AS400 has a long and illustrious history that dates back to 1988. IBM had previously introduced the System38 in 1979, along with a comprehensive product range that included the System3, System32, System34, and System36. Later, the AS400 platform was introduced together with the OS400, which enabled the porting of applications created for the System34 and System36 platforms to the AS400 platform. If you are unfamiliar with this technology, it is possible that you will not understand what AS stands for.

The initial language supported by this system was RPG, and as the system evolved, so did the support for succeeding versions of the RPG language.

Other AS400 variants and variations were gradually introduced, including: In 2000, the AS400 was renamed to theeServer iSeries; in 2006, the iSeries was renamed to theIBM System I and in 2008, all of the systems in the System I and System p series were renamed and relaunched as theIBM Power Systems.

Updates were also made to the operating system, and the whole table is provided below for your convenience. Hardware by the year OS1988 AS400 OS4002000 iSeries OS4002006 System I i5/OS2008 Power SystemIBM iSeries OS4002006 System I i5/OS2008 Power SystemIBM iSeries

Have a sneak peek into the architecture

Despite the fact that it is simple to use for the end user, IBM I has a sophisticated internal design. It is integrated with other components such as hardware, software, security, a database, and so on. In comparison to other systems, the AS400, now known as IBM Power System, is exceedingly modern, distinctive, and incredibly versatile, allowing it to easily adopt new technology. When designing IBM I it was important to keep the software and hardware distinct so that changes in one did not influence the other.

This is how the AS400 is able to control its own independent software and hardware segments.

It is important to note that the file system in IBM I is an integrated file system (IFS).

From AS400 to IBM i-quick updates

Despite the numerous problems and general lack of interest in humans, technology has its own unique charm. The most distinguishing aspect of the IBM I system is that it was designed from the beginning to be object oriented. To put it another way, while Linux regards everything as a file, including devices such as printers, IBM I treats everything as a collection of objects. The AS400/IBM i-series is capable of supporting a variety of languages. This operating system supports a wide range of programming languages, including RPG, assembly language, C, C++, Pascal, Java, EGL, Perl, Smalltalk, COBOL, SQL, BASIC, PHP, PL/I, Python, and REXX.

It is prohibited to use multiple ILE languages in the same executable and to call procedures written in any of the other ILE languages.

Other tools supported include: Synon Accelerator, LANSA, IBM Rational Business Developer Extension Uniface and GeneXus, CA Plex, and IBM Rational Business Developer Extension (formerly AllFusion Plex)

Important characteristics of IBM i

Kernel with an object-based model: As we stated before, the AS400 or IBM I OS treats every file or device as if it were an object. The fact that IBM I OS offers additional special features as compared to other operating systems is explicitly stated in the text. For instance, single level storage, which ensures the stability and security of an enterprise system, is one of them. Offerings of integrated components: The IBM I series is unique in that it comes pre-installed with a large number of fundamental functions and utilities.

  1. With the ability to execute more than 300 activities spanning from backup and recovery to communication to operations and security, this integrated system is exceptionally resilient and efficient.
  2. You may utilize IBM autonomic technologies to conduct a variety of low-priority jobs on an IBM I system, for example.
  3. In turn, this minimizes the complexity of administration as well as the expense of your energy use.
  4. Firmware virtualization solution: When discussing software-based virtualization solutions such as VMware, XEN, or HyperV, one of the most significant disadvantages is that they are not firmware-based.

In most cases, this results in a deterioration in performance. In order to understand what efficiency actually means, you need a firmware virtualization solution, and the IBM I series is the one-stop answer.

Since inception AS400 promises reliability and security, is it really true?

Since its inception, OS400, the operating system of the AS400 server, has featured five security settings with values ranging from 10, 20, 30, 40, and 50. Despite the fact that the value 10 setting has become obsolete and has been deleted from the most recent IBM I system, the other four values remain and are utilized in accordance with the business needs of enterprises. Level 10: It made no assurances about the security of any kind. It was not necessary to enter a password in order to sign into the terminal session.

  1. Sign on password security is provided at level 20, which implies that once a person has logged in, he or she will have access to all of the system’s objects.
  2. Level 30: This level grants users the ability to perform object-level operations.
  3. Level 40: This level is currently the default option in all IBM I systems, including the mainframe.
  4. All requests that originate from unauthorised interfaces are denied access to the system.
  5. It is suggested that enterprises use the greatest level of security possible since this guarantees that data is protected in an impenetrable manner.
  6. It is possible to implement level 40 without using Level 30 if you are experiencing software troubles with level 40.
  7. The appropriate use of OS/400 Group Profiles is one of the most effective methods of maintaining object level access restrictions.
  8. Then implement your access controls on the group profiles rather than on the individual user profiles.
  9. When we talk about Level 20, there are concerns regarding security.
  10. The question is, what happens if you are utilizing a legacy system that is configured to level 20 or 30?
  11. Whether you are unsure about utilizing your third-party software on an updated system, you can turn on audit logging a few weeks before upgrading the level to determine if there are any issues with the program in question.

When advancing from level 20 to level 30, the procedure might be a little time-consuming. Generally speaking, the problem emerges with legacy systems, which were previously reliant on application security and menu controls as their major means of protecting themselves.

More Power to the ‘POWER Processors’

The first power processor was introduced in the AS400 servers, which were then in use. As technology progressed, these processors became more efficient and eventually made their way into IBM Power computers. Modern CPUs are more than capable of running AIX, IBM I and Linux operating systems. IBM power9 servers, which were introduced with the 9th generation of POWER CPUs, witnessed a significant increase in popularity in 2018. When it comes to businesses and sectors, IBM I is commonly utilized in environments where dependability, efficiency, and security are of the highest importance.

The latest versions of the AS400, the IBM power systems, and the Oracle database are beneficial to SAP and Oracle database customers.

IBM collaborates with its channel partners to give the best possible service to its customers, and it also offers customized cloud solutions.

Why AS400 is rarely seen, in spite being powerful?

There are a variety of factors that have contributed to the current issues associated with the use of the AS400 or IBM i. Despite the fact that it uses cutting-edge technology and is constantly upgraded, this system has encountered problems: Many people, particularly young programmers, are uninterested in studying this technology because they believe it is outmoded. The AS400 was first introduced in 1988 and has gone through several iterations since then, which is why it is considered antiquated.

Organizations are also not dependent on AS400 or IBM I because the majority of the talent is nearing retirement age and there are no fresh programmers interested in learning about these technologies.

But it is still the heart of large scale organizations…

The AS400, now referred to as IBM I has been modernized and changed to reflect current technologies. Because it is still built on the AS400 platform, data security and authenticity are of the utmost importance. This legacy technology is being used in a modernized manner in several industries such as banking, logistics, insurance, manufacturing, transportation, and others. It is estimated that roughly 35000+ firms are employing IBM I with the majority of them being in the United States, according to Enlyft.

Top industries that use IBM i

AS400 Programming Green ScreenSource:Looking at these numbers, it is evident that this technology is not only still in use, but is also a vital element of the operations of many large technological corporations. The following are the primary reasons why leading corporations continue to place their faith in the capabilities of IBM i. It is quite scalable, since it can simply be implemented on a 4 core server and scaled up to 250 core machines in a matter of months. With proper configuration and setup, it becomes the most secure system available.

IBM I supports a wide range of native and open source languages, including RPG, Java, PHP, C++,.Net, and SQL.

The AS400 was designed to provide great redundancy and dependability, and the CPUs in the IBM I Series are 3 to 5 times more powerful than those in other brands of computers.

Although the AS400 is not currently shown in the image, it serves as the foundation for power systems that are linked with IBM i.

IBM i is today and tomorrow-In the end…

Even though many technocrats believe that the AS400 system is dead and outmoded, when you look at the facts and features of the system, the significance of this system in its upgraded configuration today cannot be overlooked. Despite the fact that it has lost a significant amount of value over time, it remains one of the most important systems for businesses, industrial industries, banking, and other sectors. Rather of being deterred, new programmers who are interested in pursuing a career as IBM I Programmers should be encouraged because this system has its origins in the past and is evolving alongside us.

Even the IBM I cloud is gaining traction in the industry and posing a serious threat to many other cloud computing platforms.

You’ve probably heard the expression ‘Old is gold,’ and in the case of the AS400, this shows to be quite accurate.
