NOVELL MAKES NO EXPLICIT OR IMPLIED CLAIMS TO THE VALIDITY OF THIS INFORMATION. ------------------------------------------------------------------ ISSUE Overview of NetWare for LAT NetWare for LAT is Novell's networking product for bidirectional connection of users and resources in the Digital Equipment Corporation (Digital*) Local Area Transport (LAT) environment and the NetWare environment. The product works with NetWare 3.11, 3.12, 4.01, or later. Terminal emulation applications running on desktop workstations connect to the NetWare for LAT server over any local area network (LAN) supported by NetWare-Token Ring, Ethernet, or ARCnet*- by means of IPX/SPX, TCP/IP, or AppleTalk* protocols. NetWare for LAT NetWare Loadable Module (NLM) applications connect to the DEC* host over an Ethernet connection by means of the LAT protocol. NetWare for LAT also supports other NLM applications that work with NetWare for LAT to integrate the NetWare and Digital environments. These third-party NLMs include products that provide bidirectional print integration, E-mail integration, and file transfer. NetWare for LAT provides you with the following capabilities: Bidirectional Connectivity. Users of either NetWare or LAT have access to the resources on the other side of the NetWare for LAT server. These resources are made available through third-party software described in this booklet. Multiprotocol Support. Connecting through NetWare provides access to LAT resources over such other protocols as IPX/SPX, AppleTalk, and TCP/IP. Examples using AppleTalk and TCP/IP are shown in the README.TXT file on the distribution diskette. NetWare Integration. You can use NetWare security, administration, and status-monitoring tools within NetWare for LAT. NetWare for LAT Server Hardware Recommendations The hardware necessary to run a NetWare for LAT server depends on the number of users that it must support and the other NLMs that are running on the server. All versions require approximately 10 MB of hard disk space. Table 1 lists the minimum CPU capacity recommended and amount of RAM required on your computer for each port configuration version of NetWare for LAT. The required minimum memory is based on the number of users. Table 1 Server Hardware Recommendations and Memory Requirements Users CPU (Recommended) RAM (Required Minimum) 16 386DX-33 MHz 8 MB 32 486DX-25 MHz 12 MB 64 486DX-33 MHz 16 MB 128 486DX2-66 MHz 20 MB Note: The data in this table assumes four sessions per user. Less memory may be required if fewer than four sessions per user are run. You can use any manufacturer's product that has Novell certification. Call Novell Labs at 1-800-NETWARE or 1-801-429-5544 to determine if the platform you are interested in has Novell certification. Third-Party Emulator Software Supporting NetWare for LAT The emulator software handles the interface logic between the workstation running the emulator and the server running NetWare for LAT. As a result, NetWare for LAT is transparent to NetWare users, enabling them to operate as if they were working at a Digital terminal directly connected to the LAT network. Table 2 lists companies announcing terminal emulation software that will be compatible with NetWare for LAT. Contact the manufacturer listed in the table for information on and availability of a particular product.

For more information on this file, see the NetWare system administration guide for the version of NetWare that you have installed. Novell recommends that you set the protocol stack SPX parameters in the NET.CFG file as follows: For OS/2* For DOS and MS Windows protocol stack spx abort timeout 60000 listen timeout 12000 retry count 40 verify timeout 6000 protocol stack spx abort timeout 1080 listen timeout 216 retry count 40 verify timeout 108 WAN Server Parameters Similarly, you can modify the server parameters for operation in a WAN environment by using the SPXCONFG utility. You can invoke SPXCONFG as a console command, or by inserting it into an .NCF file. The following line illustrates the user of SPXCONFG: LOAD [path] SPXCONFG [option[=value]] [option[=value]] Novell recommends that you set the SPXCONFG parameters to the following values: LOAD [path] SPXCONFG A=1080 V=108 W=216 R=20 The letters have the following meanings: A = SPX Watchdog Abort timeout (in ticks) V = SPX Watchdog Verify timeout (in ticks) W = SPX Ack Wait timeout (in ticks) R = SPX Default Retry Count Operating System Parameters If you are running NetWare for LAT on a NetWare 3.11 server or if you are running 64 or more users on a NetWare 3.12 server, you must set the maximum allocation of short term memory. You do not need to set this parameter for NetWare 4.x or if you are running fewer than 64 users on NetWare 3.12. Set the short-term memory as follows: SET MAXIMUM ALLOC SHORT TERM MEMORY=number Replace number with the number of bytes of memory appropriate for your number of users: Number of Users number 16 4000000 32 8000000 64 12000000 128 16000000 When running NetWare for LAT on a NetWare 4.01 server, you need to upgrade the priority of threads for proper operation when a server is especially busy. In NetWare 3.x, the threads are already high priority and need not be changed. To upgrade the threads, enter the following command line at the NetWare for LAT server console or place this line in the AUTOEXEC.NCF file: SET UPGRADE LOW PRIORITY THREADS=ON Running NetWare for LAT and NetWare for SAA* on One Server You must have NetWare for SAA 1.3B to run NetWare for SAA and NetWare for LAT on the same server. If you have a DEC host system and an IBM* mainframe or AS/400*, you may want to install NetWare for LAT and NetWare for SAA on the same server. Use the procedure outlined here to install NetWare for LAT. If NetWare for SAA Is Already Installed If NetWare for SAA 1.3B or later is already installed on the server and you want to install NetWare for LAT, follow these steps. You may have to refer to the administration guide for your version of NetWare for SAA for details on these steps. 1. Unload NetWare for SAA and the Communication Executive. 2. Install the Communication Executive that is included with the NetWare for LAT product. 3. Install NetWare for LAT and any other files that may be necessary. You can now run NetWare for SAA and NetWare for LAT from this server. If NetWare for LAT Is Already Installed If you have already installed NetWare for LAT and want to install NetWare for SAA, do not install the Communication Executive that comes with NetWare for SAA; use the Communication Executive version that is shipped with NetWare for LAT. Audit Trail Display With both NetWare for LAT and NetWare for SAA installed, the audit trail information is displayed with common column headings. The NetWare for SAA column headings now read as follows: LU is shown as P/S. Appl_ID is shown as Service. Setting Up AppleTalk or TCP/IP on a NetWare for LAT Server If you are using third-party terminal emulation software that supports the AppleTalk protocol or TCP/IP, follow the instructions contained in the README.TXT file on the distribution diskette to enable these protocols. Using Multiple Network Adapter Cards NetWare allows you bind more than one protocol to a single network adapter card (NIC). If you have already loaded a driver for the Ethernet_II frame type, you need not load that driver again. You cannot load the same frame type for more than one protocol on a single card. For optimal performance, or if you are using the same frame type for more than one protocol, use one network adapter card to connect to the LAT network and a second to connect to the NetWare network. You can then give each card a unique name for binding purposes. Novell, Inc. has attempted to supply trademark information about company names, products, and services mentioned in this document.
