# Appendix E. Sample VTAM Configurations

## Introduction

This appendix provides sample environments showing how BEA eLink for Mainframe SNA software can be configured for use with an Ethernet LAN and an APPN system 390. Considerations for token ring and subarea-style configurations are included. It is assumed that hardware and operating system installation have been completed.

An environment properly configured for the BEA eLink for Mainframe SNA system involves two general components, a local environment and a remote environment.

### Local Environment

A local environment is a UNIX-based machine running eLink SNA software. BEA eLink for Mainframe SNA is a fully bi-directional program, supporting the local system as either a client or server. This environment consists of the following components:

- Hardware: any workstation and network interface supported by the required software.

- Platform operating systems with protocol stacks (PU servers): refer to "Supported TUXEDO/WLE Platforms," in "Introducing the BEA eLink SNA System."

### Remote Environment

A remote environment is an IBM mainframe that may or may not be on the same local network. As in the local environment, BEA eLink for Mainframe SNA is a fully bi-directional program, supporting the remote system as either a client or server. This environment consists of the following components:

- Hardware: any workstation and network interface supported by the required software.

- Software: refer to "Supported Host Platforms," in "Introducing the BEA eLink SNA System."

## Sample Environments

Samples of each environment are provided to illustrate a starting point when first configuring your system. These samples are not intended to be used without modifications. Any similarity between them and any actual system is coincidental.

### Machine Attributes (LAN Descriptions)

The attributes of the sample environment machines are listed below for reference. The sample configurations refer to these attributes as required.

10BaseT carrying SNA/DLC (IEEE 802.3) and TCP/IP (DIX) traffic.

### Local Environment Configuration

HPSNAPlus2 configurations are usually setup using the HP xSnapAdmin utility, resulting in the configuration text file `/etc/opt/sna/sna_node.cfg`. This file can be manually created and/or maintained using a text editor, however, using the HP xSnapAdmin utility is recommended. The example below is the `sna_node.cfg` file for the sample environment.

### Remote Environment Configurations

You must involve your mainframe system support personnel early in the process. In a large shop there will most likely be separate individuals responsible for MVS, VTAM, and CICS. Make sure everyone is involved. Hopefully most of the configuration for your mainframe has already been done.

These samples are provided for illustration. Mainframe technical support is not trivial, and this is not intended to train you in all of the possible configurations. These samples represent one way a P390 can be configured to work in an APPN LAN environment.

#### ATCSTRxx VTAM Start List

The example below is the VTAM start list for the BEAVS P390 machine. It supports both the subarea and APPN environments.

#### XCA Major Node Defines the LAN Adapter for SYS1

This definition is set up for use with a 3172 (emulated) for connecting an APPN network node to another APPN node. Note that it is for an Ethernet LAN and the SAPADDR specified must be the same as the LSap specified for the local link station.

#### Switched Network (SWNET) Definitions

The three switched network definition examples in this section specify the VTAM PU, representing the local link stations that expect to connect with the host machine. The 10BLK and IDNUM definitions are provided to support 3270 traffic and must be unique, as well as match the values specified in the local link definition.

#### VTAM Application Major Nodes for CICS Regions

These examples represent the partner LU definitions to be accessed from the local environment. The APPL names must match those specified in the partner LU definitions on the local machine.

#### CICS Resource Definition Entries (RDO)

CICS connection and session definitions map the VTAM path definitions for the CICS application. Each connection represents one local LU definition in the local SNA configuration, therefore, the names must match.

CICS session definitions associate a VTAM mode with the LU specified in the connection. The mode names and session count characteristics must match those specified in the mode definitions for the local SNA configuration. Note that these definitions set `AUTOCONNECT` to "YES," allowing automatic session acquisition for a CICS client application.

#### Microsoft SNA Cross-Platform Definitions

It is important to communicate with the administrator of the CICS/ESA remote domain to obtain key parameters in the VTAM definition that must be included in the Microsoft SNA Server configuration, as well as in other configuration files in the eLink SNA local domain.

Before installing eLink SNA software, please examine the following general procedure for configuring the Microsoft SNA Server. Use the Microsoft SNA Server Manager GUI. Consult with the VTAM system administrator to obtain the proper values.

1. Start Microsoft SNA Server Manager.

2. Under Servers, define a server (NTSVR1):

   In the server Properties, define Server Configuration

   Server: NTSVR1

   Subdomain: NTSVR1

   Server Role: Primary

   Network Transports: TCP/IP

3. Under Link Services, define a link service (SNADLC1)

   In the link service Properties, define DLC 802.2 Link Service Configuration:

   Title: DLC 802.2 Link Service #1

   Adapter: <your ethernet adapter>

   Local Service Access Point (SAP): 0x4

   Use Fixed SAP

4. Under SNA Service, Connections, define a connection (MVSNT1.).

   In the MVSNT1 Properties, define:

   General

   Name: MVSNT1

   Link Service: SnaDlc1

   Peer System

   Both Directions

   Supports Dynamic Remote APPC LU Definition

   Address

   Remote Network Address: <host MAC address>

   Remote SAP Address: <host SAP address>

   System Identification

   Local Node Name

   Network Name: <mynetwork>

   Control Point Name: MVSNT1

   Local Node ID: <xxx nnnn> XID Type: Format 3

   Remote Node Name

   Network Name: <hostnetwork>

   Control Point Name: <vtamcpname>

   Remote Node ID: Peer DLC Role: Negotiable

   802.2 DLC

   Take Defaults

5. Under Local APPC LUs, define a local lu (LUNT1A) in the LUNT1A Properties, define:

   General

   LU Alias: LUNT1A

   Network Name: <mynetwork>

   LU Name: LUNT1A

   Advanced

   Take Defaults

6. Under Remote APPC LUs, define a remote lu (CICS1) in the CICS1 Properties, define:

   General

   Connection: MVSNT1

   LU Alias: CICS1

   Network Name: <hostnetwork>

   LU Name: CICS1

   Uninterpreted Name: CICS1

   Options

   Take Defaults

7. Under APPC Modes, define a mode (SMSNA100) in the SMSNA100 Properties, define:

   General

   Mode Name: SMSNA100

   Limits

   Parallel Session Limit: <max sessions>

   Minimum Winner Contention Limit: <min winners>

   Partner Min Winner Contention Limit: <max sessions - min winners>

   Automatic Activation Limit: 0

   Characteristics
