The IBM System i is IBM's previous generation of midrange computer systems for IBM i users, and was subsequently replaced by the IBM Power Systems in April 2. The platform was first introduced as the AS/4. Application System/4. June 2. 1, 1. 98. Server i. Series in 2. As part of IBM's Systems branding initiative in 2. System i. The codename of the AS/4. The unified product line is called IBM Power Systems and features support for the IBM i (previously known as i. OS or OS/4. 00), AIX and GNU/Linux operating systems. Summary. It was sold alongside other product lines, each with a different architecture (System/3, System/3. System/3. 4, System/3. Realizing the importance of compatibility with the thousands of programs written in legacy code, IBM launched the AS/4. In 2. 00. 6, it was again rebranded as the IBM System i. In 2. 00. 8, almost 2. System i and IBM System p product lines were combined into a new product line called the IBM Power Systems line. The operating system has undergone name changes along with the rebranding of IBM's server lineup. The operating system was rebranded as i. OS to correspond with the introduction of POWER5 processors and the rebranding of the hardware to e. Server i. Series. For the 6. 1 release, the operating system was again renamed to IBM i. The operating system is object- based. Features include a RDBMS (DB2/4. IBM 5. 25. 0), and printers. It supports security, communications, and web- based applications which can be executed inside the optional IBM Web. Sphere Application Server or as PHP/My. SQL applications inside a native port of the Apache web server. IBM i offers Unix- like file directories using the Integrated File System. Equally important are the virtual machine and single- level storage concepts which established the platform as an advanced business computer. Instruction set. TIMI is a virtual instruction set independent of the underlying machine instruction set of the CPU. User- mode programs contain both TIMI instructions and the machine instructions of the CPU, thus ensuring hardware independence. This is conceptually somewhat similar to the virtual machine architecture of programming environments such as Smalltalk, Java and . NET. They constitute an intermediate compile time step and are translated into the processor's instruction set as the final compilation step. The TIMI instructions are stored within the final program object, in addition to the executable machine instructions. This is how application objects compiled on one processor family (e. CISC AS/4. 00 4. 8- bit processors) could be moved to a new processor (e. Power. PC 6. 4- bit) without re- compilation. An application saved from the older 4. TIMI instructions into 6. The system's instruction set defines all pointers as 1. This was the original design feature of the System/3. S/3. 8) in the mid 1. When at a point in the future 1. IBM i will already be fully 1. The original AS/4. CISC models used the same 4. S/3. 8. The address space was expanded in 1. RISCPower. PCRS6. CPU processor replaced the 4. CISC processor. For 6. Power. PC processors, the virtual address resides in the rightmost 6. S/3. 8 and CISC AS/4. The 6. 4- bit address space references main memory and disk as a single address set which is the single- level storage concept. Software. While IBM i, AIX, Linux and Lotus Domino are supported on the POWER processors, Windows is supported with either single- processor internal blade servers (IXS) or externally linked multiple- processor servers (IXA and i. SCSI). Windows, Linux, and VMware ESX(VI3) are supported on i. SCSI attached servers. LPAR (Logical PARtitioning), a feature introduced from IBM's mainframe computers, facilitates running multiple operating systems simultaneously on one IBM System i unit. A system configured with LPAR can run various operating systems on separate partitions while ensuring that one OS cannot run over the memory or resources of another. Each LPAR is given a portion of system resources (memory, hard disk space, and CPU time) via a system of weights that determines where unused resources are allocated at any given time. The operating systems supported (and commonly used) under the LPAR scheme are IBM i, AIX, and Linux. Other features include an integrated DB2database management system, a menu- driven interface, multi- user support, non- programmable terminals (IBM 5. Much of the software necessary to run the IBM System i is included and integrated into the base operating system. The IBM System i also supports common client. Most AIX 5. L compatible binaries may be executed without modification or recompilation in the PASE environment. Exceptions to this are programs that contain direct calls to AIX kernel based APIs as there is no AIX kernel in PASE. If necessary an AIX program may be built directly in PASE using a standard AIX XL C/C++/C# compiler, for example if native APIs are to be used. In that case APIs are provided to translate between the AIX style pointers and the native 1. Support is provided for running both 3. AIX executables. IBM systems may also come with programming and development software like Programming Development Manager. Programming. Several CASE tools are available: CA Plex (formerly All. Fusion Plex) (see *Plex Wiki), Synon, IBM Rational Business Developer Extension, Accelerator, LANSA, Uniface and Gene. Xus. The ILE (Integrated Language Environment) programming environment allows programs from ILE compatible languages (C, C++, COBOL, RPG, Fortran, and CL), to be bound into the same executable and call procedures written in any of the other ILE languages. The IBM System i fully supports the Java language, including 3. Java Virtual Machines (JVM). Commands in the Control Language (CL) are promptable using the keyboard F4 function key, and most provide cursor- sensitive help to make specifying command parameters simpler. All command names and parameter keywords are based upon uniform standardized and mostly 3- letter abbreviations for verbs and subjects, making for easy rendering and interpretation by the application developer, as opposed to other operating systems with often cryptic or inconsistent command names for related functions or command parameter switches. For instance, the parameter keyword to apply a text description to any object to be created or changed is spelled the same way for all such commands. Examples: CRTUSRPRF, DSPUSRPRF, CHGUSRPRF, DLTUSRPRF - create, display, change, and delete user profile. CRTLIB, DSPLIB, CHGLIB, DLTLIB - Create, display, change and delete a library. ADDLIBLE, RMVLIBLE, CHGLIBL - Add or remove library list entry or change library list. CPYF, CRTF, DSPF, CHGF, DLTF - Copy, create, display, change, and delete file. WRKACTJOB - Work with Active Jobs. WRKSYSSTS - Work with System Status. STRSST, STRPASTHR, STRSBS - Start System Service Tools, start pass through (remote login), start subsystem. VRYCFG - Vary configuration, bring interfaces up or down. PWRDWNSYS - Power Down System. WRKSPLF - Work with spooled files. For traditional business programming languages such as RPG, COBOL, and C, the IBM System i provides an interface to the integrated database that allows these languages to treat database files much like other platforms treat ISAM or VSAM files. Support for 5. 25. ASCII terminals and PC workstations are equally and well supported, also via internet or LAN network access supplemented by either IBM or non- IBM communication software, for example TELNET or TELNET 5. History. The AS/4. The System/3. 6 was IBM's most successful mini- computer but the architecture had reached its limit. The first AS/4. 00 systems (known by the development code names Silverlake and Olympic) were delivered in 1. Guy Dehond from Inventive Designers was one of the beta- testers of Silverlake. The programmers who worked on OS/4. AS/4. 00, did not have a UNIX background. Dr Frank Soltis, the chief architect, says that this is the main difference between this and any other operating system. The AS/4. 00 was one of the first general- purpose computer systems to attain a C2 security rating from the NSA (Gould UTX/C2, a UNIX- based system was branded in 1. This caused problems for those who had bought third- party products that had no source and no observability. In 2. 00. 8, the introduction of V6. R1 caused similar problems, although this time IBM preferred to call it a . The product line was further extended in 2. IBM POWER5 processor. The architecture of the system allows for future implementation of 1. Although announced in 1. AS/4. 00 remains IBM's most recent major architectural shift that was developed wholly internally. Since the arrival of Lou Gerstner in 1. IBM has viewed such colossal internal developments as too risky. Instead, IBM now prefers to make key product strides through acquisition (e. Lotus Software and Rational Software) and to support the development of open standards, particularly Linux. It is noteworthy that after the departure of CEO John Akers in 1. IBM looked likely to be split up, Bill Gates commented that the only part of IBM that Microsoft would be interested in was the AS/4. This enabled programs to create, manage, and access record- oriented files on remote System/3. System/3. 8, and IBM mainframe systems running CICS. This support was extended into the AS/4. It was enhanced to support additional services that had been defined by DDM and to support AS/4. DDM. In 1. 99. 0, the AS/4. Distributed Relational Database Architecture, which is based on DDM. Hardware. It was later migrated to a POWER- based RISC CPU family eventually known as RS6. These CPUs are developed and manufactured by IBM. The POWER 4/5/5+ chips contain two cores. There are Multi- Chip Modules (MCM) available. They have 2 CPUs (4 cores) or 4 CPUs (8 cores) in one MCM. CPUYear. Clock Speed. Server- Model. Cobra (A1. MHz. Model: 4xx, 5xx. Muskie (A2. 5/A3. MHz.
