AIX (Advanced Interactive eXecutive)

AIX = (Advanced Interactive eXecutive)
is the proprietäre version of the UNIX operating system of the company IBM.

AIX history

The first version from AIX appeared in the year 1986. AIX was offered to blank, IBM RS/6000, IBM PC power Series, Motorola power stack as well as Apple network server in former times among other things for IBM PS/2, IBM. Current AIX versions support only POWER and power-PC-based hardware of IBM (PSeries and/or RS/6000) and bulletin (Escala).

Since the version 4.3 also the execution of GNU/Linux programs such as GIMP, KDE, supported GNOMES and GCC, in addition, under older versions such as AIX 3.x, 4,1 or 4,2 it was generally possible to translate and use GNU programs at that time. With the current version AIX5L the support is made clear also by L in the name.

AIX (starting from version 5.2L) supports the dynamic Repartitionieren, i.e. that when using LPAR able hardware the current operating system processors, memory and I/O adapters can be added or extracted. A restart is not necessary.
2004 were introduced the version 5.3, on IBM of eServer p5 supported and Virtualisierung and Micropartitionierung are made possible. Further innovations concern SMT support, "workload management" and a new "accounting system". Since this version it is also possible to operate AIX in a logical partition on IBM ISeries beside I5OS and Linux.

AIX characteristics

AIX5L does not offer binary compatibility to Linux (also not to the PPC Linux), but a source text compatibility. GNU /Linux programs can be implemented by native support of the Linux libraries and programming interfaces after unique Rekompilieren as native AIX programs. IBM offers the most popular GNU /Linux programs as before-compiled RPMs for AIX in the "AIX Toolbox for to Linux Applications".

AIX contains an efficient Logical volume manager, JFS and JFS2-Dateisysteme, an integrated Workload manager and many other characteristics, who are offered in other commercial Unix systems rather than liable to pay the costs extensions. The Tool mksysb makes (similarly as make_tape_recovery from the HP-UX package Ignite UX) a comfortable and boatable system safety device possible.

Since AIX 3 the system is administered over the system management interface Tool (SMIT). Instead of directly CLI instructions will enter over a menu controlled surface worked, which generates and implements the appropriate commands with parameters. The actions are logged (smit.log) and the implemented commands additionally geschreiben (smit.script). Thus one can transfer the generated commands to own Skripte.
