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.

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.

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).

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.

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.

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.

EXTENDED SERVICES

Extended Services, together with the companion product SAA Distributed Database Connection Services/2 (TM) (DDCS/2), meets the needs of OS/2 users who require access from intelligent workstations to relational databases and other communications services located locally on the workstation, across a LAN, on a remote system or host platform. Extended Services is comprised of three components:

Communications Manager, Database Manager and Query Manager. DDCS/2 is a separate product. Advantages common to the Extended Services components include: o  Multi-vendor Platform Extended Services is capable of running on a much broader hardware and software base than its Extended Edition predecessor. Database and communications functions may be used not only on IBM personal computers with OS/2 Version 2.0, but also on OS/2 Version 1.3 (refresh level 1.30.1 or later) and on selected non-IBM compatible hardware platforms and selected non-IBM OS/2 operating systems. Extended Services will support both 16- and 32-bit applications. o  National Language Support Extended Services provides multi-national solutions for customer's expanding global business needs with eleven single-byte versions including U.S. and U.K. English. o  Reliable Base Extended Services will exploit the OS/2 attributes of              preemptive multi-tasking, performance and integrity. This will allow the use of simultaneous diverse communications connectivities and protocols and simultaneous multiple database transactions in a protected environment. o  Architected Design Extended Services uses IBM's Systems Applications Architecture (SAA) including the Common User Access to enable a              consistent application appearance. Communications Manager uses Common Communications and the Common Programming Interface -- Communications (CPI-C). These facilitate the development of              distributed applications and allow their portability across the SAA family of products. Database Manager supports the portability of applications across IBM relational database platforms via the following architectures; IBM SAA SQL Level 1, Multi-vendor Integration Architecture (MIA), Distributed Relational Database Architecture (TM) (DRDA (TM)), and implements the client/server model for 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. IBM Corporation Dept.

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. To obtain a copy of these documents send a written request to              Personal Systems Programming at the following address. IBM Corporation Database Manager Products Dept. A04, Bldg. 901 11501 Burnet Road East Austin, TX 78758 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.

EXTENDED SERVICES SUPPLEMENTAL INFORMATION -- PUBLICATIONS Extended Services publications, announced as available from IBM, may be ordered at availability. PUBLICATIONS ADDED TO THE SOFTWARE SHIPMENT GROUP: o  Product Supplemental Information Document (G04G-1009) o  Communications Manager Additional Function Installation Guide (S96F-8312) o  Productivity Aids (S96F-8313) o  Communications Manager keyboard templates are added to the basic shipment group. SPECIFIED OPERATING ENVIRONMENT -- MODEMS Modem support under the Communications Manager is clarified as          follows: The following asynchronous modems are supported: COMMAND DEVICE                                                  SET Hayes Smartmodem 1200 and                               Attention IBM Series 2400                                         (Hayes) Hayes Smartmodem 2400                                   Attention Hayes V-Series Modem Enhancer 1200                      Attention Hayes V-Series Modem Enhancer 2400                      Attention IBM PC Series 1200                                      Attention ROLMphone 244PC                                         Attention MicroCom AX/2400C                                       Attention Racal-Vadic VI2422S                                     V.25bis Other modems that comply to the Hayes Attention Command Set or          to the V.25bis standard are, with some limitations, also supported by           the Extended Services Communications Manager. For example, the IBM 7855 Modem is supported in a Hayes-compatible mode; however, the full V.32 function set is not available under Extended Services. Synchronous Modem Support -- Communications Manager supports IBM modems conforming to the CCITT V.25/V.28 (EIARS232D) interface standards, and also IBM-compatible vendor modems conform to the same standards. 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. .-.            |   Memory Estimating Worksheets for Extended Services            | |---++|            |                                   |   Recommended      | User   | |Functions                         |   Memory (MB)      | Config.| |---++|            |Operating System:                  |Standard            |        | |                                  |Edition     OS/2    |        | |                                  |V1.3        V2.0    |        | |---++|            |Base                               | 1.5         2.5    |        | | DOS Compatibility                | 0.5 (1)     0.5 (2)|        | | Windows Compatibility            | N/A         1.0 (2)|        | | High-Performance File System     | 0.3         0.5    |        | | Active Spooling (while printing) | 0.3         0.5    |        | | Systems Performance Buffer (3)   | 0.5         0.5    |        | |Communications Manager            |                    |        | | Base (required for               |                    |        |             |  communications)                  |        0.2         |        | | 3270 Terminal Emulation (4)      |        0.4         |        | | 3270 Host Print                  |        0.3         |        | | SNA Gateway (5)                  |        0.1         |        | | 5250 Workstation Feature (5)     |        0.2         |        | | ASCII Terminal Emulation         |        0.3         |        | | APPC/APPN                        |        0.4         |        | | LUA (5)                          |        0.2         |        | | File Transfer (6)                |        0.3         |        | |Database Manager                  |                    |        | | Database Services (stand-alone)  |        1.4         |        | | Database Client (7)              |        0.5         |        | | Database Server (8)              |        2.6         |        | | Each Additional concurrent       |                    |        | |   process                        |        0.2         |        | | Query Manager                    |        1.6         |        | |Dist.

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. .-.            |   Memory Estimating Worksheet for OS/2 LAN Server Workstations  | |+|            | Components                                     |   Memory (MB)  | |+|            | Base operating system                          |                | |  Base (OS/2 SE 1.3)                           |       1.5      | |  DOS Compatibility                            |       0.5      | |  High Performance File System (HPFS)          |       0.3      | |  Active Spooling (while printing)             |       0.3      | |  System Performance Buffer (1)                |       0.5      | | LAN Server 2.0:                               |                | |  Server (required):                           |                | |    Domain controller                          |                | |      Entry Package (2)                        |       3.5      | |      Advanced Package (3)                     |      10.0      | |    Additional server                          |                | |      Entry Package (2)                        |       2.5      | |      Advanced Package (3)                     |       9.0      | | User Profile Management (4, 5) (required)     |       ___      | | LAN Adapter and Protocol Support (4, 5)       |       ___      | |  (required if the loop back                   |                |             |   driver is not installed)                     |                | | First Failure Support Technology/2 (4, 5)     |       ___      | |  (required)                                   |                | | DOS LAN Requester Download service (6)        |       ___      | | DOS Remote IPL service                        |       0.6      | | OS/2 Remote IPL service                       |       1.1      | | Loop Back Driver                              |       0.1      | |  (required if LAN Adapter and Protocol        |                |             |   support is not installed)                    |                | | Uninterruptible Power Supply Support          |       0.2      | | Generic Alerter service                       |       0.1      | | OS/2 LAN API Structures (6)                   |       ___      | | Migration Import Utility (7)                  |       ___      | | LAN Services installation/configuration       |       0.6      | |  program (for server, when in use)            |                | | OS/2 LAN Online Reference and Help panels (6) |       ___      | | OS/2 LAN Command Reference (6)                |       ___      | | DOS LAN Requester Online Reference (6)        |       ___      | | 386 HPFS (5, 8)                               |       ___      | | Fault Tolerance for Fixed Disk (8)            |       0.1      | | Local Security for the 386 HPFS (8)           |       0.2      | | Applications (9)                              |       ___      | | Applications data (10)                        |       ___      | |+|            | 1.This additional system memory allows better performance for   | |  for transient conditions such as program loading, program     | |  termination, and print spooling. |            | 2.Includes default cache disk size of 512KB, which allows good  | |  good performance with less RAM cost. |            | 3.Includes a cache size of 6MB recommended for best performance | |  with the Advanced package. |            | 4.This component is common to LAN Server 2.0 and the IBM        | |  Extended Services program. |            | 5.The memory required for this component is included in the     | |  the Server number. |            | 6.No memory required;

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:
 * IBM Developers Toolkit for OS/2 Version 2.0
 * IBM Developers Workbench for OS/2 Version 2.0.

OS/2 2.0 DEVELOPERS TOOLS SERVICE AND SUPPORT

All service channels and enhanced support offerings as described in OS/2 Service and Support except OS/2 Support Line are available to users of OS/2 Version 2.0 Developers Tools. Refer to OS/2 VERSION 2.0 SERVICE AND SUPPORT for details.
