AIX

See also: Aix

AIX is the Operating system of the type UNIX of IBM. AIX is the Acronyme of Advanced Interactive executive , but only the acronym is used.

AIX was designed for IBM by INTERACTIVE Systems starting from IN/ix based on Unix System V Release 2. The first version was launched in January 1986 with the Ordinateur IBM RT-PC. The system was related to the computers IBM PS/2 and IBM System/370. In 1990, AIX version 3 left with IBM RS/6000. Following an alliance with IBM, Bull has a contract OEM with IBM to sell the waiters PowerPC and POWER using AIX, which makes the first IBM customer of it all over the world. Bull takes part in the development of AIX, as well as waiters supporting it (pSeries). Motorola, Harris, General Automation and Apple also supported AIX. In the long run, it improbable that it is replaced by GNU/Linux, from now on is not supported by IBM.

Positioning compared to the others *IX

  • AIX had the reputation among its users to be incoherent with the other systems *IX. A usual joke was that its acronym meant “Ain' T Unix” ( it is not Unix ). In practice, UNIX had already so much mixed alternatives of BSD and System V that few people really knew where was the standard, nor even only if whoever had defined one of them. The problem is found to a lesser extent between distributions different of Linux (tools of administration and different high level installation).
  • Some interesting ideas of AIX include orders such chuser, mkuser, rmuser and other things similar, making it possible to manage the accounts in the same way that files.

Test of differentiation

To offer a a little gravitational side, AIX version 3 also had in 1990 some assets:
  • Management of the logical volumes (noncontiguous disk spaces, therefore extensible upon request, and seen like consecutive) out of standard.
  • interactive Assistance in hypertext (all documentation) out of standard
  • interactive Assistance in mode full screen with the management of the system (with possibility of generation of scripts) out of standard.
  • But largest differentiating of AIX compared to another Unix is truly the utility " SMIT " who allows to manage the system since the recognition of the peripherals until the management of the licenses and the management of clusters (and to indicate on request the detail of the corresponding orders).

The involuntary asset

However, one of the reasons of the success of AIX 3.0 at the beginning was ignored of IBM, and the customers hid it to him more the possible for a long time: IBM did not have with the departure thought of of invoicing its software maintenance like the other suppliers, and had kept the policy of specific in the past exemption from payment to its great systems. The terms of the contracts did not make it possible to return on this involuntary gift, but the situation was corrected in this respect as of the following version of AIX.
