DESCRIPTION
The   IBM   Advanced  Interactive   Executive   (AIX)   Operating
System Version 1.1  provides enhancements and service  updates to
Version  1.0  of  the  AIX   Operating   System,   which   became
available in May 1986.
Shared Libraries
The   shared  library  capability allows  users  to specify  that
certain  routines be  shared  among  several executing  programs.
Routines  to be   shared  are   stored   in  special   libraries,
designated  as "shared"  libraries.   Programs  that share  these
executable   routines  do   not  link   to   the  routines  until
run-time,   and  share   a  single   in-memory   copy  of   these
routines with other executing programs.
The  use  of  shared library routines  can eliminate the need for
redundant  copies   of  common   routines   in    memory   during
execution,   and redundant  copies on  disk with  the storage  of
object programs.  In some high  usage multi-use systems,  the use
of  shared  library routines can improve performance of programs.
Advanced Display Graphics Support Library
The  Advanced Display  Graphics   Support   Library  provides   a
program   interface for  graphics applications  to  the IBM  6153
Advanced   Monochrome  Graphics   Display   and   the  IBM   6154
Advanced    Color  Display,      and   the   IBM  6155   Extended
Monochrome Graphics Display.   This interface includes a   set of
graphics primitives  designed to  achieve high  performance.  The
graphics primitives can be called by programs written in IBM   RT
PC FORTRAN 77,  IBM Pascal,  and  the  C   compiler provided with
the AIX Operating System.
Functions  provided by  the  Advanced  Display Graphics   Support
Library include:
o Adapter initialization and termination
o Line, multiline, and polyline drawing
o Line drawing logical operations
o Solid rectangle and polygon fill
o Fixed pitch text painting
o User defined character fonts and cursor functions
o Keyboard,   mouse,   tablet,   dials,    and   lighted  program
function key facilities
o Query for display type, active font, mouse/tablet
Graphics Device Drivers
Version 1.1  of the  AIX Operating  System includes   a  set   of
device    drivers  for   several   of   the  graphics   displays,
printers, and plotters that have been  announced by  IBM  for the
IBM 6150 Micro  Computer. These device drivers  are equivalent to
the drivers announced  with the IBM 6150  Micro Computer Graphics
Development Toolkit  (see IBM Product Announcement  dated January
21,   1986.)    Object   programs   that   require  these  device
drivers  at run-time  can now  execute under  the AIX   Operating
System    without   the    requirement    to    have   the    IBM
Graphics Development Toolkit installed.
The graphics device utilities support the following:
o Displays
- IBM 6154 Advanced Color Graphics Display
- IBM 6153 Advanced Monochrome Graphics Display
- IBM 6155 Extended Monochrome Graphics Display

- IBM 6180 Color Plotter
o IBM 6150 Micro Computer Mouse
Enhancements to the C Compiler
The  AIX  Operating System Version 1.1 includes the addition of a
global  optimizer  to  the  C  compiler.    The  global optimizer
is  designed  to   improve  the  performance  of  C programs that
have been compiled under Version 1.1 of the  C compiler.
Optimizations   provided  with   Version 1.1  of  the C  compiler
include:
o Elimination of unused variables
o Constant folding -- propagation and evaluation
o Code motion of loop invariants
o Operator assignment benefits
o Elimination of common subexpressions
o Register allocation
o Value identification
Version 1.1  of the  C compiler  also provides  the addition   of
single   precision   floating  point   operations,   and   shared
library support.
Usability Services Enhancements
A function has  been added to the Usability  Services  portion of
the AIX  Operating System  to provide  an improved  interface for
users  to customize  the TOOLS window.  This function  is part of
the TOOLS  application,  and  allows  the  addition, modification
and  deletion  of   Tools  Groups  or commands.   Also, Usability
Services now supports  the  IBM  5083  Tablet (Models  11 and 12)
as an optional pointing device.
TCP/IP
Major functions include:
o Simple  Mail  Transfer   Protocol (SMTP) to send  outgoing mail
to other hosts
o File Transfer  Protocol (FTP)  to send,  retrieve,  delete,  or
rename  files  sent  between  the user  and server or between two
hosts
o Telnet Protocol to allow remote logging to another host
o Network    services     commands    to      support     network
definitions, maintenance, and problem determination
o Trivial  File Transfer Protocol (TFTP)  to read and write files
(or mail) to and from a remote server
Other Functional Enhancements
System   installation   functions  have    been    enhanced    to
facilitate   re-installation   of  the   AIX   Operating  System.
Files added by other programs can be  preserved,  backup  of user
modified    system    files  is   provided,   and   customization
information is saved when customization files are updated.
System  shutdown has   been  modified   to   allow  shutdown   to
single  user  mode for maintenance, and warning messages are sent
to all users, with a time delay to  allow  for  logging off.
Additional   configuration   aids  include   extensions   to  the
"display"  command to  control colors   and   fonts  on   locally
attached  displays, and new "ulimit"  options to control text and
data sizes of programs.
Performance Enhancements
Several  enhancements designed  to  improve  performance are   in
Version 1.1 of the AIX Operating System, including:
o Kernel buffer options to allow automatic sizing based on system
memory size, and to allow unpinning of the kernel buffers.
o File  name  and  directory  caching in memory for faster access
to data.
o Modifications to process scheduling,  semaphore operations, and
mapped file operations.

SCHEDULE
PLANNED GENERAL AVAILABILITY:  September, 1986.
TECHNICAL INFORMATION
SPECIFIED OPERATING ENVIRONMENT
HARDWARE REQUIREMENTS
The  minimum  machine requirement is an IBM with  a display (e.g.
the IBM 6150 Micro Computer Advanced Color Graphics Display,  the
IBM  Advanced Monochrome   Graphics Display, or the  IBM Personal
Computer  Display). The  IBM  PC  Network Adapter   (6450213)  is
required  by the  Base PC   Network Services   program portion of
the AIX Operating System. The   IBM  Baseband  Adapter (61X6810),
or equivalent, is required to use the TCP/IP facilities of AIX.
Optionally,  an  asynchronous modem can be installed for use with
Asynchronous     Terminal     Emulation,     UUCP,     or     the
Connect(10)   command.     Program  support   is   provided   for
asynchronous    modems     that     support     the     following
specifications:  EIA RS-232C Standard (dated  August 1969) or the
CCITT  Recommendations  V.24/V.28  as  published in the report of
the CCITT  7th  Plenary  Assembly  (Yellow  Book), Geneva,  10-21
November   1980.     Program   support    is  also  provided  for
auto-dialer modems that  conform  to  the  "AT" command set using
asynchronous protocol.

SOFTWARE REQUIREMENTS
There   are  no   software prerequisites  for  the AIX  Operating
System.
SECURITY, AUDITABILITY AND CONTROL
User  management is  responsible  for  evaluation, selection  and
implementation   of   security   features,   for   administrative
procedures,   and   for  appropriate   controls   in  application
systems.  For applications in which sensitive data  is  sent over
external communication  facilities, user  management may  wish to
pursue the application of cryptography.
The  TCP/IP support  does not  encrypt  or   decrypt  user   data
transmitted  across the  network.    The   design   of  the   IBM
Baseband   Adapter and  associated VRM  Device  Drivers allow  an
application program to  access only those  packets   addressed to
that 6150 node.  A user should assess the security of the network
and the  exposure of information assets  as  a  result  of  using
some of the features of  TCP/IP and similar network communication
protocols.
When users are added  to the system they are assigned  a  User ID
and   assigned   to  a  group.   They  may  also  be  assigned  a
password,  which is  required at  sign-on time.   Each group   is
allowed  access  to  files based on the authorization of the file
owner.
A file  may be  accessed  by   its  owner   and  by   groups  (of
users).    A group may be allowed  full access, or the access may
be limited based on the file owner's authorization.
PLANNING INFORMATION
CUSTOMER RESPONSIBILITY
The  customer is  responsible for  the installation  and use   of
those licensed programs.
Customers   who  order   the  AIX   Operating   System  are   not
required  to order  the  separately  available Virtual   Resource
Manager  Licensed Program,  since  the  Virtual Resource  Manager
function is included as part of the AIX Operating System.
To   use  shared   libraries  or   the  enhancements   to  the  C
Compiler,  including   floating  point   enhancements   and   the
global compiler optimizer, user programs must be re-compiled with
Version 1.1 of the AIX Operating System.
NATIONAL LANGUAGE SUPPORT
These   software  products  are  dependent  on national  language
character handling.  The  product should be reviewed  relative to
the  national  language  requirements  of  the  intended customer
before ordering.
User-developed    applications   that  have   been   written   to
process World Trade  data may access  characters   represented on
World Trade keyboards.
The    Telnet   protocol    treats    the    decimal  value   255
(hexadecimal  FF) as  a flag  indicating that  a  control   value
follows;   therefore   the  following   characters  will  produce
unpredictable results if entered under Telnet:
n acute (lower case)
"therefore" symbol (three dots)
The  software keyboard  mapping  table   default   is  the   U.S.
English  keyboard layout.   When a national language  keyboard is
being  installed,  one  of   the  respective  language   software
keyboard   mapping  tables   can  be  selected  from diskette  to
override  the system   default.    The   system   will  then   be
powered   up  using  the override  mapping table  for the  system
keyboard.
