Chapter 1: Overview of 3+0pen and LAN Manager Installation

This chapter provides an overview of 3+Open, 3+0pen LAN Manager, and Server-Adapted MS OS/2, including examples of network environments where you can use 3+0pen. It also provides an overview of the procedure for installing the 3+Open LAN Manager software.

3+0pen

3+Open is a family of local area network products based on the multitasking operating system, MS OS/2. Its open architecture enables you to operate a wide variety of standard MS OS/2, MS-DOS, and Macintosh computers on a network. It uses the many features of MS OS/2 while maintaining compatibility with MSDOS computers and applications.

3+Open supports several network protocols, including Xerox Network Systems (XNS), NetBIOS Protocol (NBP), and IBM Data Link Control (DLC).

3+Open provides a standardized full-screen interface. This interface is modeled on IBM's Systems Application Architecture (SAA) interface standards. The interface makes it easy to learn and use 3+Open. You can also use 3+Open with the standard MS OS/2 and MS-DOS command line interface.

Overview of 3+0pen and LAN Manager Installation

3+0pen LAN Manager

At the core of 3+Open is the 3+Open LAN Manager, the network system software. 3+Open LAN Manager has the following features:

•Security system that allows the network administrator to regulate access to network resources and to audit resource use.

•Logon scripts and user profiles that give the user automatic access to the same network resources, regardless of where the user logs on.

•Error logging and compilation of network usage statistics.

•PostScript® despooler and a facility for administering it.

•3+Open DOS Manager, which provides a window-oriented file management feature for DOS netstations and memory-saving applications for DOS computers.

•Netsetup, the program that automates installation of the LAN Manager on personal computers, sets tuning parameters to standard values, and configures printer services.

•Enhanced version of the MS OS/2 software.

3+0pen LAN Manager is described in greater detail in the 3 +Open MS OS/2 LAN Manager Administrator Guide and the 3+0pen MS OS/2 LAN Manager User Guide.

Versions of 3+0pen LAN Manager

Three versions of 3+Qoen LAN Manager software exist. They provide the same function, but differ in the number of network workstations (netstations) they support.

•3+Open LAN Manager Advanced System is licensed for installation on one server and an unlimited number of netstations.

•3+Open LAN Manager Entry System is licensed for installation on one server and up to five netstations. Only one Entry System can exist on a network.

•3+Open LAN Manager Entry System II is licensed for installation on one server and up to ten netstations. Only one Entry System II can exist on a network.

The 3+Open LAN Manager software runs on 3Com 3Server servers and mM or ffiM-compatible personal computers. This guide helps you install the software only on mM and ffiM-compatible personal computers. The 3+Open for 3Servers Installation and Setup Guide explains how to install the software on a 3Server.

3+0pen Network Environments

You can use 3+Open in a variety of network environments, including the following:

•Networks consisting of one server and multiple netstations all using the same protocol. This is the "basic" network configuration.

•Basic networks extended to support multiple protocols concurrently. In this configuration, not all netstations use the same protocol. For example, some use XNS, while others use DLC.

•Networks connected by a server bridge. The server could have multiple network adapters and, if necessary, use multiple protocols to link multiple networks.

•Concurrent communications between servers and netstations using 3+Open, 3+Share®, and 3+Share for Macintosh software.

Chapter 2: MS OS/2 Installation and Disk Cache

Before you can install the 3+Open LAN Manager software on your server, you must install OS/2 version 1.0 or 1.1 software on your server. It is recommended that you install the Server-Adapted MS OS/2 version 1.1 software that is shipped with the 3+0pen LAN Manager software. However, you can use other vendors' versions of the software.

This chapter leads you through the installation of the Server-Adapted MS OS/2 software on your server. You should install this software only on a server, not on a netstation, as per your license agreement. The chapter also includes instructions on setting up your MS OS/2 disk cache.

Server-Adapted OS/2 Software

Server-Adapted MS OS/2 software offers these benefits:

•Disk-caching to speed up perfonnance.

•Hard disk partitions of up to 4 gigabytes (GB) in size.

•Maximum file size of 2 GB.

System Requirements

To set up and use MS OS/2, your server must be a personal computer with the following features:

•An 80286 or 80386 processor.

•At least 4 megabytes (MB) of random-access memory. If you have added extra memory to your computer, make sure the memory is extended memory, not expanded memory.

•At least 8.2 MB of space available on drive C.

•One high-density floppy disk drive.

Installing MS OS/2

Before you begin installing MS OS/2, make sure you have the following five diskettes handy:

•OS/2 Server Adaptation Installation Disk

•OS/2 Server Adaptation Disk #1

•OS/2 Server Adaptation Disk #2

•OS/2 Server Adaptation Disk #3

•OS/2 Server Adaptation Disk #4

To install the OS/2 software, follow these steps:

1.Insert the IAN Manager OS/2 Server Adaptation Installation Disk into your floppy disk drive.

2.Start your server. If your server is already running, press [Ctrl]+[Alt]+[Del].

The installation program displays a welcome screen, explaining that the program will lead you through the installation of the MS OS/2 software, and prompting you to insert the other installation disks when needed.

The remainder of this section contains additional information that you might need while installing the MS OS/2 software.

Formatting the Hard Disk Before Installation

One of the first questions that the installation pro~am asks you is whether or not you want to use the FDISK utility to create, modIfy, or resize partitions on your server's hard disk. You must run this utility for a new server and for servers that have been running an operating system other than MS-DOS or MS OS/2. Refer to the MS OS/2 User's Guide for information on how to use the FDISK utility.

NOTE: Before you run the FDISK utility on a server that has been running an operating system other than MS-DOS or MS OS/2, you must do a low-level format of the server's hard disk. Refer to the manufacturer's documentation for instructions.

The recommended range for the MS OS/2 partition size is from 16 to 127 MB. Although the FDISK utility accepts other values, partitions that are larger or smaller than the recommended sizes make less efficient use of the hard disk.

CAUTION: Back up your hard disk before adding, deleting, or changing partitions with the FDISK utility; modifying partitions erases data from the hard disk.

2-5

Choosing an MS OS/2 Environment

The installation program prompts you to choose one of three MS OS/2 environments:

•Presentation Manager, a graphics-based screen environment with windows and menus. In this environment, you can run several screen groups simultaneously, each in its own window, with a different program in each.

•Program Selector, a command-line environment that supports multiple screen groups. This environment uses 1 MB less memory than Presentation Manager. It is also the mode you must choose if you are going to use the server as a dedicated server (a server that is only a server, not a server and a netstation).

•Minimum Shell, a command-line environment that supports only one screen group. The single screen group restriction is for security; unauthorized users cannot start a new screen group in order to circumvent security.

2-6

MS OS/2 Installation

and Disk Cache

MS OS/2 Disk Cache

A disk cache improves server perfonnance by using memory to temporarily store data that is moving between programs and the hard disk. There are two types of disk caching: read caching and write caching, also known as lazy write.

With read caching, blocks of data are read from the disk into a program and into the cache. If the same data is requested again, it is instantly available from the cache.

With write caching, data destined for the hard disk is temporarily stored in the cache until the server can write it to the disk without taking processing time away from other activities. Write caching can also save writes to the disk by updating data while it is still in the cache.

CAUTION: With write caching, data in the cache is lost if you turn your server off without fIrst clearing the cache, or if power to your server is interrupted. To avoid data loss, perfonn one of the following steps:

•Press [Ctrl]+[Alt]+[Del] to restart the server.

•Stop the cache with the command:

cache /stop

•Stop write caching with the command: cache /lazy:*:off

For more infonnation about the CACHE command, refer to "CACHE Command" later in this chapter.

2-7

Setting Default Cache Size

The default cache size at installation is 512 KB. The minimum allowable cache size is 64K, and the maximum allowable cache size is 7.2 MB. To change the default cache size, edit the diskcache= entry in the CONFIG.SYS file. To set the default size to 1 MB (1024K), for example, change the diskcache= entry to:

diskcache=1024

There are no rules for cache size other than the minimum and maximum sizes stated earlier. However, the larger your cache, the better it works. For example, it is a good idea to set your default cache size to 1 MB or more if you can spare the memory. Use the CACHE command to change the cache size as you work, if necessary.

CACHE Command

The CACHE command lets you view or change the configuration of your disk cache. The syntax for the command is as follows:

cache options

The options for the CACHE command are listed and explained in Table 2-1.
