AIX ( A dvanced I nteractive e X ecutive ) is a Unix - Operating system of the company IBM and for use in server systems or in workstations aligned.
history
The first version of AIX appeared in 1986. AIX was previously offered for IBM PS / 2 , IBM RT , IBM RS / 6000 , IBM PC Power Series, Motorola PowerStack and Apple Network Server , among others . Current AIX versions support only power - and PowerPC -based hardware from IBM ( pSeries or RS / 6000) and Bull (Escala).
Starting with version 4.3, the execution of GNU / Linux programs such as GIMP , KDE , Gnome and GCC is supported, but it was also generally possible to compile GNU programs from that time under older versions such as AIX 3.x, 4.1 or 4.2 and to use. With the AIX5L version, the support was also made clear by the "L" in the name.
AIX (from version 5.2L) supports dynamic repartitioning, which means that processors , memory and I / O adapters can be added or removed from the running operating system when using LPAR- compatible hardware . A restart is not necessary.
2004, Version 5.3 was introduced on the IBM eServer p5 is supported and virtualization and Micro Partitioning allows. Further innovations concern SMT support, “workload management” and a new “accounting system”. Since this version it is also possible to run AIX in a shell on the IBM iSeries in addition to i5 / OS and Linux .
AIX 6.1 was shipped in November 2007. For the first time in the history of AIX, there was an "open beta" program for this version in which anyone could participate. In addition to supporting the latest hardware, AIX 6.1 also offers additional virtualization features such as workload partitions, application and partition mobility, as well as a whole range of new security functions (Enhanced RBAC, Encrypted File System, Trusted AIX and Trusted Execution etc. .). The striking "L" for Linux affinity was removed from the product name in version 6. The aim is to illustrate the big leap from v5r3 to v6r1 (many new features, the break with the 32-bit kernel), to represent the harmonization with the Power6 processors and to dispel customers' fears about the future of AIX in coexistence with Linux .
features
AIX5L offers no binary compatibility with Linux (not even with PPC Linux), but source code compatibility . Thanks to native support for Linux libraries and programming interfaces , GNU / Linux programs can be run as native AIX programs after being recompiled once. IBM itself offers the most popular GNU / Linux programs as precompiled RPMs for AIX in the "AIX Toolbox for Linux Applications".
AIX includes a powerful Logical Volume Manager , JFS - and JFS2 - file systems , integrated workload manager and many other features that are offered rather than fee-based extensions in other commercial Unix systems. The mksysb tool enables (similar to make_tape_recovery from the HP-UX Ignite-UX package) a convenient and bootable system backup.
Since AIX 3, the system can be managed using the System Management Interface Tool (smit). Instead of entering command line commands directly , a menu-driven interface is used that generates and executes the appropriate commands with parameters. There are two versions available: smit ( X-Window-based ) and smitty (on the command line, the word is made up of “smit” and “tty”); both have identical options. The actions are logged (smit.log) and the commands executed are also written (smit.script). This means that you can use the generated commands in your own scripts.
