Establishing an LU 6.2 connection

This section describes how to establish an LU 6.2 connection using Communications Manager/2 Version 1.11. You may use any of the supported LU 6.2 products for this platform. The panels would look different from those shown but most of their content would be similar.

Defining local node characteristics

To set up the local node you need to perform these tasks:

1. Configure a DLC.
2. Configure the local node.
3. Add a local LU.
4. Add a transaction program definition.
5. Configure a mode.

To define the local node characteristics:

1. Start the Communications Manager/2 Installation and Setup program by typing CMSETUP on an OS/2 command line, and pressing Enter.

   
   
   
   

2. Press OK to continue.
3. Press Setup to create or modify a configuration.
4. Specify a name (up to 8-characters) for a new configuration file (1), or select the one that you wish to update. The following examples guide you through the creation of a new configuration file. Treat them as a guide if you are modifying an existing configuration.

   
   
   
   

5. Press Yes.

   
   
   
   

6. Press Yes.

   In this example we set up connections using APPC over Token-ring. The following screen appears in two stages. When you first see it, highlight the line:

   APPC APIs through Token-ring
   

   The complete screen appears as shown below.

7. Press Configure....

Configuring a DLC

1. 1. On the APPC APIs through Token ring panel, complete the values for Network ID ((2)) and Local node name ((3)).

   2. Select End node - no network node server.
   3. Click on Advanced.
   4. Select DLC - Token-ring or other LAN types and press Configure....
   5. Enter the value for C&SM LAN ID. This should be the same value as the Network ID entered earlier ((2)).
   6. Leave the remaining default values and press OK.

Configuring the local node

1. Select SNA local node characteristics and press Configure....
2. Complete the value for Local node ID (hex) ((4)) using the values in your configuration worksheet.
3. Press Options...
4. Complete the value for Local node alias name ((5)) and press OK.
5. Press OK.
6. Select SNA features and press Configure....

Adding a local LU

1. Select Local LUs and press Create....
2. Complete the fields LU name ((6)) and Alias ((7)).
3. Press OK.

Adding a transaction program definition

1. Select Transaction program definitions and press Create....
2. Complete the values for Transaction program (TP) name ((8)) and OS/2 program path and file name ((9)). If you are going to use Attach Manager to start the listener program, specify the Program parameter string, for example -m OS2 -n MQSERIES.
3. Press Continue....
4. Specify that the program is to be run in the Background and that it is to be Non-queued, Attach Manager started.
5. Press OK.

Configuring a mode

1. Select Modes and #INTER and press Change....
2. Ensure that the default values match those shown above and press Cancel.
3. Press Close to close the SNA Features List window.

Local configuration is complete.

The following sections describe how to create connections to other nodes.

Connecting to a peer system

To set up a connection to a peer system the steps are:

1. Adding a peer connection
2. Defining a partner LU

Start from the Communications Manager Profile List panel.

Select SNA connections and press Configure....

Adding a peer connection

1. Select To peer node and press Create....
2. Select Token-ring or other LAN types and press Continue....
3. Specify a Link name ((11)) and check Activate at startup.
4. Complete the fields LAN destination address (hex) ((12)), Partner network ID ((13)), and Partner node name ((14)).
5. Press Define Partner LUs....

Defining a partner LU

1. Complete the fields Network ID ((13)), LU name ((15)), and Alias ((16)).
2. Press Add.
3. Press OK.
4. Press OK.
5. Press Close.

If you have connections to make to other platforms repeat this section as appropriate.

If you have made all the connections you require proceed to Verifying the configuration to complete Communications Manager/2 configuration.

Connecting to a host system

To set up a connection to a host system, for example z/OS or VSE/ESA, the steps are:

1. Adding a host connection
2. Defining a partner LU

Start from the Communications Manager Profile List panel.

Select SNA connections and press Configure....

Adding a host connection

1. Select To host and press Create....
2. Select Token-ring or other LAN types and press Continue....
3. Specify a Link name ((11)) and check Activate at startup.
4. Complete the fields LAN destination address (hex) ((12)), Partner network ID ((13)), and Partner node name ((14)).
5. Press Define Partner LUs....

Defining a partner LU

1. Complete the fields Network ID ((13)), LU name ((15)), and Alias ((16)).
2. Press Add
3. Press OK.
4. Press OK.
5. Press Close.

If you have connections to make to other platforms, proceed to the appropriate section.

If you have made all the connections you require proceed to Verifying the configuration to complete Communications Manager/2 configuration.

Verifying the configuration

1. Press Close to close the Communications Manager Profile List panel.
2. Press Close.
3. Press Yes.
4. Press OK.
5. Press Close.

What next?

The LU 6.2 connection is now established. You are ready to complete the configuration. Go to MQSeries for OS/2 Warp configuration.
