OVERVIEW DESCRIPTION
OS/2 VERSION 2.0
WORKPLACE SHELL: The OS/2 Version 2.0 Workplace Shell sets the
standard for ease-of-use in the personal computer industry. The
object-oriented approach allows users to manage many types of objects
-- programs, data files, printers, network servers and drives -- from
a single interface called the desktop. From the desktop, users can
directly manipulate objects so that printing, for example, becomes as
simple as dragging and dropping a picture (or icon) representing a
letter onto an icon representing a printer.
The Workplace Shell works the way users do, and it can look
the way users want it to look. More flexible than ever, OS/2
Version 2.0 allows users maximum freedom to customize desktops,
including colors, fonts, object locations and many other aspects of
appearance. Desktops may look very different from one user
environment to another and from one user to another.
The Workplace Shell represents the culmination of earlier
technologies, evolving over time from the command line to graphical
icons, to the current object-oriented interface technology, which
implements the workplace model defined by Common User Access (TM)
(CUA (TM)) 91. OS/2 Version 2.0 is the Systems Application
Architecture (R) (SAA) environment for the workstation. The
Workplace Shell makes OS/2 Version 2.0 an excellent desktop operating
environment for all users today and advances operating system
technology for tomorrow.

INTEGRATING PLATFORM: The OS/2 Version 2.0 desktop provides a single
environment from which a mixed set of applications -- DOS, Windows
(1), 16-bit and 32-bit OS/2 -- can be started. Users can display
most of these applications and their corresponding data
simultaneously. OS/2 Version 2.0 automatically manages system
resources such as memory, processor, hardware devices, programs and
data files on behalf of all types of applications running
concurrently on the system.
(1) Trademark of Microsoft Corporation.
CONCURRENT EXECUTION: OS/2 Version 2.0 supports the concurrent
execution of tasks, permitting users to perform other tasks while
processing one or many other tasks. This reduction in waiting time
improves user response times and efficiency. Depending on the
display adapter installed, users generally can run applications
windowed or full screen, in graphics or text modes, and in the
foreground or background. Full-screen operation in the foreground
may be required or preferred for some advanced graphical applications
where performance or timing considerations are critical.
INTERPROGRAM COMMUNICATION: "Cut and paste" can be performed easily
across all types of applications, reducing the need for manual
transfers of data and the resulting risk of errors. Dynamic Data
Exchange (DDE) is supported between Windows and OS/2 Presentation
Manager (R) applications. Object linking and embedding (OLE) is
supported between Windows applications.
(R) Registered trademark of International Business Machines
Corporation.
PRINTING: Each printer is represented on the OS/2 desktop by a print
object, enabling users to drag and drop print jobs onto any local or
remote printer on the network. This smooth, integrated operation
allows users to improve productivity by significantly decreasing the
number of steps needed to print.
NETWORK SUPPORT: OS/2 Version 2.0 meets the needs of today's users
who work in interconnected environments. OS/2 Version 2.0 provides
robust networking and client-server capabilities, underscoring the
benefits derived from IBM's unique systems know-how. Network
servers, such as the IBM LAN Server and the Novell NetWare server,
represented as objects on the OS/2 desktop, allow users easy access
to the services of local and remote servers. When access is needed,
OS/2 Version 2.0 prompts users for information, so they no longer
must remember complex commands.
In addition, users no longer need to assign drive letters or
port names to use the resources on the network. From the OS/2
Desktop, users can browse servers for shared resources; they can
browse shared disks for files and programs and they can browse shared
printers to manage print jobs.
APPLICATION AND SYSTEM PROTECTION: In addition to being the desktop
operating system of choice, OS/2 Version 2.0 is the platform ideally
suited for running mission-critical and line-of-business
applications. OS/2 Version 2.0 is a protected system and application
environment. Each application is encapsulated in its own address
space and cannot access system or other application data. DOS and
Windows sessions run in the protected mode of the 80386 processor.
If a Windows or DOS application (running in a window) attempts to
violate the integrity of the system, the application will be ended
gracefully without affecting the system and other executing
applications. And, if DOS or Windows applications fail (for example,
Unrecoverable Application Errors (UAEs)), that DOS session can be
closed and restarted easily without affecting the other applications
running on the system.
MULTIMEDIA APPLICATIONS: OS/2 Version 2.0 supports applications that
utilize OS/2 and Windows multimedia extensions, allowing users to
integrate multimedia applications into their environment. Users can
look ahead to the next generation of software programs -- exciting
multimedia solutions for entertainment and education.
APPLICATION COMPATIBILITY: A very broad range of the current 17,000
DOS applications, 4,900 Windows applications, and 2,500 16-bit OS/2
applications will run unchanged on OS/2 Version 2.0. This vast
assortment of applications permits users to choose the applications
that provide the most effective solutions to their needs. This means
that businesses do not need to invest in new applications and
training right away;. they can migrate to the emerging, more
powerful, 32-bit OS/2 applications as their needs grow.
IBM has subjected leading applications, based on market share
and use of specialized functions, to rigorous testing. In addition,
a large number of users have tested their applications on early
versions of the OS/2 Version 2.0 product. IBM is aware of a very
small number of applications, such as those that could compromise the
integrity of the system or those requiring extremely high interrupt
rates (typically, greater than 1,000 interrupts per second) that will
not operate properly. Other applications may run with limited
function or may require special settings. Refer to the OS/2
COMPATIBILITY INFORMATION in the OS/2 Version 2.0 package for
details.
VERSION-SPECIFIC DOS: Some applications must run on a specific
version of DOS. OS/2 Version 2.0 allows users to boot (start)
specific versions of DOS, such as Versions 3.3, 4.0 and 5.0 or DRDOS
Version 6.0 in a DOS session. This capability helps to ensure
compatibility with DOS version-specific applications and device
drivers, including block device drivers (such as LAN requesters)
needed for network support.
BOOT MANAGER: OS/2 Version 2.0 allows users to boot (start) multiple
operating systems, such as DOS Versions 3.3, 4.0 and 5.0; DRDOS
Version 6.0; and OS/2 Version 1.3, on the same hardware system on
which OS/2 Version 2.0 is installed. This ability to boot multiple
operating systems allows applications requiring a specific operating
system to run on a single hardware configuration. The boot manager
feature also allows businesses with large numbers of users migrating
from one release to another to fully test the new environment while
the old environment continues to be operational.
MEMORY EXTENDERS: OS/2 Version 2.0 provides portability for the
current set of DOS applications by adhering to current industry
standards for personal computing. The ability of OS/2 Version 2.0 to
execute DOS applications that use XMS, EMS, and DPMI (level .9)
prevents existing DOS applications from becoming obsolete due to
migration to OS/2 Version 2.0. While EMS is fully supported,
performance is optimized for XMS and DPMI.
ADOBE TYPE MANAGER (1) (ATM (1)): OS/2 Version 2.0 includes the
Adobe Type Manager, which supports industry-standard ATM fonts for
Windows and Presentation Manager applications. Support for Windows
applications requiring ATM fonts allows users to run their
applications under OS/2 Version 2.0 without purchasing and installing
the ATM for Windows. A selection of popular ATM fonts (Type 1) is
also included.
(1) Trademark of Adobe Systems, Incorporated.
INSTALLATION: Rich colors, icons, progress indicators and status
information all help to guide users easily through the new OS/2
Version 2.0 graphical installation. When installing over DOS,
Windows, or a previous version of OS/2, applications and other
environmental conditions are preserved or migrated to exploit the
OS/2 environment.
Users can choose from two preselected installations, one
optimal for most users, and another that installs the complete
system. A third installation option enables users to install only
the functions they need, reducing hard disk requirements. While a
60MB hard disk is required, actual hard disk requirements range from
15-30MB, depending on the installation options selected. OS/2
Version 2.0 also supports installation from a response file. The
response file is a very efficient way of installing the system on
many machines that need to be configured in the same way by allowing
a system administrator to pre-select the installation options. The
response file and the ability to install OS/2 Version 2.0 from any
drive, including a LAN, help to reduce user involvement in the
installation. Refer to OS/2 Version 2.0 Remote Installation and
Maintenance (Red Book) (GG24-3780).
MIGRATION: During installation, OS/2 automatically migrates existing
DOS, Windows and OS/2 environments, mapping them to the OS/2
Version 2.0 environment. In addition, OS/2 Version 2.0 contains
profiles of more than 225 of the most popular DOS and Windows
applications, which are placed in the appropriate DOS or Windows
folders on the OS/2 desktop; OS/2 Version 1.X groups are mapped to
OS/2 Version 2.0 folders on the desktop. OS/2 Version 2.0 also takes
care of the special settings required by a few of the 225 DOS and
Windows applications. This migration process also includes the
supporting DOS, Windows, and 16-bit OS/2 device drivers and printer
definitions and other applications on the hard disk. Users can
achieve the look of OS/2 Version 1.3 to help migrate to the Workplace
Shell. Refer to the WORKPLACE SHELL section of this document.
ONLINE HELP AND INFORMATION: The "Start Here" icon on the OS/2
desktop contains a selectable list of the tasks users perform most
frequently, such as adding and using programs, finding information,
printing and shutting down systems. Users can select the task they
need to perform and move directly to the procedure for accomplishing
it in the Master Help Index.
Online help and information is available at any time and
provides users with instant explanations of OS/2 Version 2.0
functions, eliminating the need to keep a manual nearby. The online,
interactive tutorial teaches users how to use a mouse, how to work
with objects, how to optimize the windowed environment and how to use
the online help and information.
The Master Help Index contains an alphabetic, selectable list
of topics, enabling users to quickly locate instructions for
completing any task supported by the OS/2 Version 2.0 product. Each
topic contains hypertext links, allowing users to select a topic of
choice and view related information immediately. Topics can also be
searched and printed easily.
PRODUCTIVITY AIDS AND GAMES: The productivity aids and games
(applets) included with OS/2 Version 2.0 provide a basic level of
program function intended to help users learn to use the system and
become productive immediately.
Productivity aids -- calculator, calendar, notepad, and sticky
pad help users perform and manage daily tasks. A to-do list acts as
a reminder; an alarm helps to ensure tasks are done on time. Daily
and monthly planning programs help users keep track of upcoming
events. PM Terminal opens up a new experience for users unfamiliar
with the world of online databases and bulletin boards. The Enhanced
Editor and the PM Chart programs are useful for daily tasks and
presentations. In all, 18 productivity applets are included.
Games -- Games provide entertainment and help users unfamiliar
with a mouse to practice their skills. The computer gives users a
run for their money if they try to defeat it at OS/2 Chess.
Klondike-style Solitaire is a favorite, along with Jigsaw, Scramble
and Reversi.
HARDWARE EXPLOITATION: OS/2 Version 2.0 is supported on personal
computers with an 80386SX (or compatible) or higher processor, with
at least 4MB of memory and a 60MB hard disk with 15-30 MB of free
space. Refer to the STATEMENT OF SERVICE section for additional
information.
IBM has tested key functions of the OS/2 Version 2.0 product,
based on selected model configurations provided by the manufacturer
of non-IBM hardware systems. Testing results are available on
CompuServe, NATBOARD, the National Support Center Bulletin Board
System, the OS/2 Bulletin Board System, IBM Forums (OEM and OS2ARENA)
and IBMLink (TM).
(TM) Trademark of International Business Machines Corporation.
PRINTERS
OS/2 Version 2.0 supports a broad range of printers, producing
high-quality printed output from OS/2, Windows and DOS applications.
OS/2 Version 2.0 exploits the printers customers use most, including
IBM, Hewlett-Packard, Epson, Panasonic and many others. In addition,
OS/2 Version 2.0 includes a corresponding set of the most popular
Windows printer drivers. The multitasking capabilities of OS/2
Version 2.0 allow users to save time by running DOS, Windows and OS/2
printing jobs in the background.
DISPLAY ADAPTERS
OS/2 2.0 supports a wide variety of DOS, Windows and OS/2
applications running side-by-side in windowed sessions when the
primary display adapter (including adapters that support SVGA modes)
is configured for VGA mode. OS/2 2.0 supports DOS applications
running side-by-side in windowed sessions in most SVGA modes on
certain display adapters. OS/2 2.0 also supports text-based DOS
applications running side-by-side in windowed sessions when the
display adapter is configured for XGA (TM) or 8514A modes. Broader
support for high-resolution modes (higher than 640x480x16) will be
provided over time. In addition, IBM is working with the
manufacturers of popular boards to assist them in making their
Windows and Presentation Manager drivers available. Information will
be available on CompuServe, NATBOARD, the National Support Center
Bulletin Board System, the OS/2 Bulletin Board System, IBM Forums
(OEM and OS2ARENA) and IBMLink.
(TM) Trademark of International Business Machines Corporation.
OTHER PERIPHERAL DEVICES
OS/2 Version 2.0 supports a broad range of hardware devices,
including hard disk drives, diskette drives, tape drives, CD-ROM
drives, optical disk drives, display adapters and pointing devices.
Support for devices utilizing the Small Computer System Interface
(SCSI) includes chaining of commands, significantly improving
throughput. In addition, OS/2 Version 2.0 provides a complete SCSI
solution by supporting the Micro Channel (R) and PC-bus-based
architectures.
Some FAX and sound adapters are extremely timing sensitive,
requiring more than 1,000 interrupts per second. These adapters may
not operate successfully in DOS sessions.
OS/2 Version 2.0 allows all applications to access disks
formatted with the High-Performance File System (HPFS) and enhanced
file allocation table (FAT) file system. The enhanced FAT file
system provides better performance than FAT, and the HPFS provides
extremely fast access to very large disk volumes. In addition, the
2GB limitation on the size of each disk volume has been raised.
Theoretically, the new limit is 64GB, but a practical, usable size is
5-7GB (per volume). This support for very large disk volumes
increases the productivity of network administrators, who no longer
must continually move and delete data to free disk space.
(R) Registered trademark of International Business Machines
Corporation.
SYSTEM PERFORMANCE: OS/2 Version 2.0 allows application developers
to create applications that exploit the 32-bit architecture. These
capabilities include 32-bit instructions and data addressing, a flat
memory model capable of supporting programs with address spaces as
large as 512MB, the interrupt and task switching managers needed to
accommodate 32-bit save and restore operations and an enhanced 32-bit
loader. Most 32-bit applications perform faster on OS/2 Version 2.0
than their 16-bit counterparts. Over time, as more applications are
written to take advantage of the power of 32-bit OS/2 Version 2.0,
additional performance improvements should be realized.
The ability of OS/2 Version 2.0 to run multiple tasks
concurrently helps to improve the productivity of users; tasks
previously performed end-to-end can now be run in parallel. 32-bit
OS/2 Version 2.0 was designed to run in a minimum of 4MB of memory,
and in that environment, the benefits of concurrent tasking can be
realized. However, to unleash the power of complex applications
running in multitasking environments, hardware should not be a
constraint.
Combinations of all types of applications -- DOS, Windows and
OS/2 -- running together on the system benefit from the predictable
performance of the OS/2 Version 2.0 environment. OS/2 Version 2.0
runs applications with performance equal to or better than their
native environments.
Unlike the cooperative multitasking used by Windows
applications, which depends on applications voluntarily sharing
system resources with other applications (and which must be written
specifically to share resources), the preemptive multitasking scheme
implemented by OS/2 Version 2.0, reserves control for the system
itself, balancing the performance of all the applications running on
the system.

support of database applications running on DOS, Windows and OS/2
client workstations.
o LAN Improvements
Adoption of the new LAN Adapter and Protocol Support
(LAPS) provides more efficient processing of the IEEE 802.2 and
NETBIOS protocols with increased performance in both cases across
supported LANs.
o Productivity Aids
Seven new productivity aids will be shipped with Extended
Services to supplement and enhance usability. Included are print
and file transfer utilities, a keyboard utility, a problem
determination tool, APL support and a database performance
optimization tool.
- PCPRINT -- supports printing to one or more PC printers with
a wide selection of printers, queues, drivers and fonts.
Printing may be from PC, VM or MVS/TSO files with many
pagination options.
- ALMCOPY -- supports uploading or downloading files between a
PC and a System/370 VM host. Facilities such as wild card
naming enhance performance, particularly with multiple file
transfers.
- TOGGLE -- provides additional keyboard and mouse support to
facilitate control of and navigation between 3270 sessions.
- SNAPDUMP -- is a set of tools designed to facilitate problem
determination. It collects data from multiple sources
including errors and traces, packages it for review and has
options for forwarding the data to other service points.
- APL -- provides support for host APL under a 3270 session.
APL characters may be input from the keyboard or received
from the host and displayed and printed.
- Host Printing via Printer Definition Tables -- provides
additional function and control for 3270 printing. It
enables the "rotate" facility and enhances performance for
many printers.
- EXPLAIN -- provides the database programmer with a tool to
help analyze SQL statements and optimize performance of
database applications.
A new publication is shipped with Extended Services which
describes each application.
o Extended Services Installation
It is possible to install Extended Services from a drive
other than "A". The drive can be a shared drive on an IBM LAN
Server Version 2.0 system, other network server systems, or an
alternative local drive. For example, when connected to an IBM
LAN Server Version 2.0 system a user can specify the network
drive and execute Extended Services installation with no
diskettes required. This installation is much faster and easier
across the LAN.
o NetWare Compatibility
Extended Services (Database Manager and Communications
Manager) may coexist on a network with Novell NetWare LAN
requesters and servers. In addition, NetWare LAN requesters may
be installed on the same workstation as Extended Services.
Instructions for the installation of the NetWare requester for
OS/2 are included in the NetWare Services for OS/2 product.
Users will find additional information in the OS/2 LAN Server and
NetWare from IBM Coexistence Guide, and should refer to the
COEXIST.TXT FILE in the NetWare Requester before installing the
requester with either Extended Services or the LAN
Server/Requester.

COMMUNICATIONS MANAGER (CM)
The Communications Manager component of Extended Services provides
extensive support for terminal emulation, diverse connectivities
using several different protocols, traditional and peer networking
and gateways within a single offering, tailored to individual user
requirements. By utilizing the advanced capabilities of OS/2, the
functions of Communications Manager can be run simultaneously as a
reliable service to the users. In addition, Communications Manager
has powerful support for application developers, system and network
administrators.
o End User Support
CM provides 3270, 5250 and ASCII terminal emulation, each
containing or having access to associated file transfers.
Multiple windowed sessions may be run simultaneously to help
boost the productivity of the user. Broad connectivity support
allows applications (such as database or user developed) to
access data locally on the workstation, across the LAN or across
a WAN to remote hosts or services.
o Application Development Support
A very broad range of Application Programming Interfaces
(APIs) is available serving the LAN, WAN, Emulator, Distributed
Application, Services and Systems Management environments.
Applications may be developed as 16- or 32-bit, the latter using
the IBM C Set/2 compiler, which supports the following APIs:
CPI-C, APPC, Common Services, System Management, EHLLAPI,
NETBIOS, and IEEE 802.2
For development error correction CM has traces and error
logs. In addition, CM provides the associated underlying code to
help the communications links function correctly and
simultaneously. The application developer concentrates on the
application, confident that the communications support will work
correctly and efficiently.
o Systems and Network Management Support
For installation, CM has several alternative configuration
options ranging from simple to comprehensive, and from manual to
programmed. The incorporation of Advanced Peer-to-Peer
Networking (APPN) from the previous NS/2 product greatly
simplifies the setup and modification of these types of networks.
Remote Operations support in conjunction with 370 NetView (R)
gives centralized workstation administration and control. The
use of First Failure Support Technology (TM) (FFST (TM)/2) for
the automatic logging of LAN errors as they occur is a powerful
new tool just beginning to be used with CM. Finally, the
availability of the SNAPDUMP productivity aid provides another
powerful tool for tracking errors should they occur.
o Other Features
SNA gateway support now allows the simultaneous use of up
to 254 workstations through the Communications Manager's SNA
Gateway attached via a single or multiple adapters. Successful
operation in a given environment may depend on other factors,
such as application load and/or line speed, so the ability to
exploit a full complement of 254 workstations should not be
assumed for all cases. Note that the total number of LU sessions
(254) per gateway, an SNA limit per PU, is not increased. The
maximum number of workstations in any configuration utilizing a
single gateway is 254 with a single LU for each. If performance
is perceived to be unsatisfactory, the use of a more powerful
gateway computer could be considered.
3174 Peer Communications enabling (together with
associated support at the controller) allows coax-attached
workstations to enjoy many of the benefits of Token-Ring LAN
membership, including the ability to use APPC applications.
CM supports the Network Device Interface Specification
(NDIS). Existing and future adapters conforming to NDIS may be
used and exploited in support of Extended Services. Information
about the support of NDIS Media Access Control (MAC) device
drivers and the availability of independent testing can be
obtained by writing Personal Systems Programming at the following
address. Customers who have already requested and received an
IBM OS/2 NDIS Driver Implementation Package will receive new
information automatically.

o Migration
All previous versions of CM applications written to
published APIs are upwardly compatible with Extended Services.
Any level of CM may use any level of the SNA gateway, providing
maximum flexibility in the migration process.

DATABASE MANAGER
The Extended Services Database Manager is an integrated host and
desktop relational database providing consistency with IBM's
SAA-related family of database products. Two versions of Extended
Services are offered. The Extended Services for OS/2 is a single
user package that provides native database capabilities to either a
stand-alone or LAN-attached workstation. This version can also be
configured as a client to a remote database server installed on the
LAN or to the host. Extended Services with Database Server for OS/2
is the server version of the product providing database support to
DOS, Windows or OS/2 client workstations through its client enabler
Distributed Feature. Access to host databases is possible for either
version when IBM SAA Distributed Database Connection Services/2
(DDCS/2) is also installed.
o Flexibility
In addition to the APIs supported by earlier versions, the
Database Manager's menu of programming interfaces is supplemented
with a SQLEKILL interface. This interface permits a database
administrator to force users off without bringing the database
down so that functions like backup and restore can be performed.

FAX (512) 838-0050
o Connectivity
In addition to access across supported LANs, the Database
Manager with the Communications Manager component and the
Distributed Database Connection Services/2 (DDCS/2) software
product, provides transparent access from the Database Manager to
IBM's DRDA host relational databases, requiring no separate host
access code. Access can be from a single workstation with DDCS/2
installed or from DOS, Windows or OS/2 client workstations
through a comparably equipped database server.
o Price/Performance
Using OS/2 Version 2.0 increased memory capabilities,
Database Manager can support additional database clients,
additional concurrent databases and enhanced performance tuning.
Extended Services is repackaged to provide a single user
version and a low-cost client/server solution. Extended Services
database servers support older Extended Edition Version 1.2 or
1.3 APPC or SQLLOO clients. These clients and Extended Services
database clients can access shared databases on a LAN or at a
host. The maximum number of configurable applications is
increased to 252. However, successful operation in this
environment is dependent on factors such as application load and
available memory.
o Ease-of-Use
Database Manager's ease-of-use is improved for system
administrators through the addition of APPN and NETBIOS support.
Both support methods provide simplified configuration processes
when compared to earlier releases. For experienced SQL users, a
command line interface is provided for quick entry to database
functions. Access to both LAN and host databases is supported
from the OS/2 command line.
o Reliability and Integrity
Database Manager provides an outstanding platform for
mission critical applications through its support of roll-forward
recovery, transaction management, concurrency, declarative
referential integrity and backup functions to user-specified
devices (for example, tape, disk, LAN server, host and optical
disk).
First Failure Systems Technology/2 (FFST/2 (TM)) and
expanded trace facilities allow users and systems administrators
to easily diagnose and solve problems. Logging of errors and
other pertinent trace information occurs at the time of failure,
eliminating the need to recreate the error scenario.
o Investment Protection
Databases created under earlier versions of the Extended
Edition's Database Manager can be easily migrated for use with
Extended Services. This migration is automatic when using Query
Manager the first time a connection is made to the database. The
MIGRATE1 command can be issued from the OS/2 command line.
Extended Edition databases backed up and later restored using
Extended Services can be migrated automatically. Application
programs can migrate databases using the "SQLEMIGD" API.
Using IBM's C SET/2 compiler, 16-bit applications can
exploit the OS/2 Version 2.0 32-bit operating system for
increased performance and portability.
Existing Extended Edition Version 1.2 and 1.3 DOS clients
and Extended Services clients can coexist and access the same
Extended Services database concurrently. While Extended Services
database servers will support Extended Edition clients, Extended
Services clients are unable to access the earlier Extended
Edition database servers.
o Productivity and System Management
A set of graphical DBA tools assist in database
administration, catalog management, configuration, archiving and
backup of data.
To assist in performance tuning, an "EXPLAIN" tool is
packaged as a productivity aid in Extended Services. EXPLAIN
provides and obtains access path selection information about an
SQL statement to be executed and can be used to determine if
performance tuning or resource management changes should be
considered or if RE-ORG or RUN-STATS on a table would be
beneficial. This "as-is" product, previously available through
OS2Tools and ESDTools, is provided in direct response to customer
requests.
(TM) Trademark of International Business Machines Corporation.
DDCS/2
IBM's SAA Distributed Database Connection Services/2 product
is a separately packaged product that, when installed with Extended
Services, provides transparent access to IBM's relational database
family of products. Read/write connection is provided to the
appropriate version of DB2 (R), SQL/DS (TM) or OS/400 host databases.
DDCS/2 comes in either a single user or multi-user version.
The single user version can be installed on either version of
Extended Services for host access by that workstation. The
multi-user version can be installed only on the Extended Services
with Database Server for OS/2 product and provides host access for
DOS, Windows or OS/2 clients.

PLANNING INFORMATION
MEMORY AND HARD FILE ESTIMATING WORKSHEETS: The following worksheets
may be used to help determine hardware capacity requirements for OS/2
configurations. To estimate requirements, add the recommended memory
or hard-file size for the base operating system and the Extended
Services functions and components desired. These totals plus
sufficient buffer must be added to the capacity in megabytes required
for other user applications and the requirements for user data.
The numbers shown in the worksheets give the recommended
memory size in megabytes for concurrent operation of the functions
listed and not the total size of all the code and data areas that
comprise the functions. The quantities shown assume an acceptable
degree of swapping. Refer to the Memory Management Techniques in the
Extended Services Information and Planning Guide for a description of
the method used to develop these quantities as well as for more
detail and reference scenarios.
Some users may begin to tax the capacity of available
workstations and servers as function is increased. In some
situations it may be desirable to move to faster and higher capacity
hardware to maintain desired performance.

- Online publications and graphical aids provide on-screen
information
- Redesigned, customer-oriented library structure makes
information more accessible
o The new OS/2 LAN Server Version 2.0 meets customers' needs for
advanced function, performance, reliability, integrity and
ease-of-use by exploiting OS/2 advanced capabilities.
- LAN Server 2.0 -- Entry offers improved performance, compared
to LAN Server 1.3, at a very attractive price.
- LAN Server Version 2.0 -- Advanced offers the same faster LAN
transport as the Entry package and provides a 386
high-performance file system. The Advanced server performs
1.1 to 2.5 times improved performance to the requester over
OS/2 LAN Server Version 1.3.1 and is 2.0 to 5.0 times more
efficient (CPU utilization) than LAN Server Version 1.30.1.
The superior performance of the Advanced package is
particularly evident in heavy workload environments such as
the remote IPL of OS/2 Requesters.
- LAN Server Version 2.0 -- Entry is recommended for a LAN
environment with the following characteristics:
-- New LANs with up to 18 concurrent remote IPL requesters.
-- New LANs with up to 32 active users. Fewer users are
recommended for heavy activity such as concurrent
transferring of data to/from the server and more users
may be supported for medium activity such as reading a
file from the server, manipulating it at the requester,
then storing it at the server. Additional users can be
logged on, but not active.
- LAN Server Version 2.0 -- Entry running on OS/2 Version 2.0
is recommended for 32-bit server application development in
the LAN environment described above.
- LAN Server Version 2.0 -- Advanced is recommended for a LAN
environment with any one of the following characteristics :
-- Workloads greater than recommended for LAN Server
Version 2.0 -- Entry
-- Fault tolerance is required
-- Local security is required
-- Optimum performance is desired

diskette may also be used in the OS/2 2.0 remote install
procedure.
MEMORY AND DASD
MEMORY AND FIXED-DISK ESTIMATING WORKSHEETS: Use the following
worksheets as guidelines in determining the memory and fixed-disk
requirements for each server or requester workstation on your
network. Add the size required for the server or requester product
to the size required for the operating system (the OS/2 program for
OS/2 LAN Server and OS/2 LAN Requester; DOS for DOS LAN Requester)
and the size required for each application. Include an allowance for
user application data. Refer to "Hardware, Memory, and Fixed-Disk
Requirements" in the LAN Server Network Administrator Reference
Volume 2 for considerations regarding memory and fixed-disk size.
Fixed-disk requirements for workstations on your network are
changed if you follow the advanced installation path during
installation or if you provide users of workstations with custom
installation diskettes. In both cases, more efficient use can be
made of the available fixed-disk space, because only the code
relevant to the components or functions specified is installed.
Note, however, that the advanced path also allows installation of
more functions, which may cause a workstation to require more
fixed-disk space. In the following worksheets, requirements for OS/2
LAN Server and OS/2 LAN Requester are given for each installable
function, to easily determine required memory or fixed-disk space.
The memory requirement is less if the user does not run all
installed functions and applications concurrently. System memory
requirements are based only on applications and functions that run
concurrently. Note also that memory requirements vary from
application to application and depend on the conditions under which
each application is used.
Using less than the recommended memory may increase the time
required to switch from one function or application to another,
reduce keystroke responsiveness, or reduce throughput. For the
impact of caching, buffers and tuning, refer to "Performance Tuning"
is the LAN Server Network Administrator Reference Volume 2.
With one fixed disk on a workstation, the LAN Services
installation/configuration program allows a user to select the fixed
disk on which to install LAN Services. Note, however, that User
Profile Management, LAN Adapter and Protocol Support, and First
Failure Support Technology/2 are always installed on the boot drive.
NOTE: Determine and install the proper memory and disk capacities and
select the programs to achieve intended results. The customer is
responsible for the installation of, use of, and results obtained
from the machines and programs.
IBM does not warrant or otherwise guarantee any performance or
usability results implied by this data. Ensure that adequate
hardware configuration flexibility exists to accommodate possible
changes, such as future enhancements, new customer applications and
increased user data requirements.

representative or, if eligible, obtain installation and usage
assistance through IBMLink. Customers who purchase through an IBM
Authorized Dealer should seek support through the dealer channel
unless qualified for support from some other direct channel, such as
IBMLink.
Extended Services and LAN Server customers may choose to
service their software through IBM's SystemXtra for Personal Systems.
Refer to the SYSTEMXTRA section for details.
For further details, refer to Extended Services Programming
Announcement 291-599, and/or LAN Server Programming Announcement
291-630, dated October 22, 1991.
OS/2 VERSION 2.0 TOOLS FOR APPLICATION DEVELOPMENT
IBM OS/2 Version 2.0 tools for application development provide
a complete 32-bit C-language application development environment.
With these tools, the developer can take full advantage of the rich
programming interface in OS/2 Version 2.0. The tools are packaged to
allow the application developer to start up on OS/2 Version 2.0 with
a small investment and continue to use their own favorite tools.
Productivity and technological gains may be made by moving all
development work to OS/2 Version 2.0 and moving up to 32-bit
object-based application development for OS/2 Version 2.0.
THE DEVELOPMENT PLATFORM OF CHOICE
The power and performance of preemptive multitasking coupled with
application protection make OS/2 Version 2.0 the right system for
application development. In a multitasking system with the developer
managing a number of projects, some of which are being debugged and
experiencing failures, it is essential that system integrity be
maintained. OS/2 Version 2.0 provides the power and integrity to
handle this environment. Development for 32-bit OS/2, for 16-bit
OS/2, and for DOS/Windows can co-exist on OS/2 Version 2.0. IBM
WorkFrame/2 makes the job easier by organizing the developer's
projects and integrating preferred tools into a single, easy-to-use,
graphical environment.
POWERFUL 32-BIT APPLICATION PROGRAMMING INTERFACE
OS/2 Version 2.0 has a rich and powerful programming interface
designed to take application development into the future. The System
Object Model (SOM), used to build the Workplace Shell, enables
developers to fully integrate applications into the Workplace Shell
using object-oriented technology. Via Workplace Shell APIs, the
application's objects derive all the benefits of the Workplace
functions such as drag and drop. Using the SOM Compiler, the
C-language programmer can extend this function and define new class
libraries. The IBM OS/2 Version 2.0 Application Design Guide
explains how to build OS/2 Workplace Shell and SOM enabled
applications while maximizing performance with 32-bit memory
management, multithreading, interprocess communications, preemptive
multitasking and other features of OS/2 Version 2.0.
The IBM Developer's Toolkit for OS/2 Version 2.0 and the IBM
OS/2 Version 2.0 Technical Library enable the application developer
to take full advantage of the OS/2 Version 2.0 programming interface.
The Toolkit provides essential tools such as the PM Resource
Compiler, the IPF Compiler, and the SOM Compiler. The Toolkit also
includes the API Reference in online form, sample programs that
demonstrate the use of the new APIs, the required header and .LIB
files, and kernel debug support. The Technical Library supplements
the Toolkit with programming guides, API references in printed form,
and additional information about REXX, CUA, and device driver
development. All of these books, including the Application Design
Guide, may be purchased as a group in the Library or individually; an
order form is provided in the Toolkit.
APPLICATION PERFORMANCE AND PROGRAMMER PRODUCTIVITY
High performance code optimization in the IBM C Set/2 C compiler
provides the opportunity to produce some of the highest-performing
OS/2 based applications possible. Extensive runtime library support,
online hypertext reference information, conformance to ANSI and SAA
standards, and a fully graphical, full-function, source-level PM
debugger all make C Set/2 an excellent choice for developing 32-bit
OS/2 Version 2.0 applications. Organizing C Set/2 projects in
WorkFrame/2 further enhances programmer productivity.
PROTECTING INVESTMENT IN 16-BIT CODE
Mixed-mode programming techniques supported by OS/2 Version 2.0 and C
Set/2 enable the integration of 16-bit code into 32-bit programs.
For example, the user may continue to develop panels using Dialog
Manager, a 16-bit Presentation Manager interface previously provided
in the IBM OS/2 Programming Tools and Information Version 1.3; this
code can be incorporated into a 32-bit executable that takes
advantage of the 32-bit interface provided by OS/2 Version 2.0. Both
the 32-bit development environment (C Set/2 with tools) and the
16-bit development environment (a 16-bit compiler with tools) can be
installed in WorkFrame/2 to enhance productivity in the mixed-mode
environment.
SUPPLEMENTAL INFORMATION
Minor modifications to the product names of the Toolkit and Workbench
were made after the announcement dated October 22, 1991. The correct
product names are:
o IBM Developers Toolkit for OS/2 Version 2.0
o IBM Developers Workbench for OS/2 Version 2.0.
