Establishing an LU 6.2 connection

This section describes how to establish an LU 6.2 connection.

Local node configuration

To configure the local node, you need to:

  1. Create a line description
  2. Add a routing entry

Creating a line description

  1. If the line description has not already been created use the command CRTLINTRN.
  2. Specify values for Line description ((6)) and Resource name ((7)).

  2. Specify your value for Subsystem description ((5)), and the values shown here for Routing entry sequence number, Compare value ((8)), Starting position, Program to call, and the Library containing the program to call.
  3. Type the command STRSBS subsystem description ((5)) and press Enter.

Connection to partner node

This example is for a connection to an OS/2 system, but the steps are the same for other nodes. The steps are:

  1. Create a controller description.
  2. Create a device description.
  3. Create CPI-C side information.
  4. Add a communications entry for APPC.
  5. Add a configuration list entry.

Creating a controller description

  1. At a command line type CRTCTLAPPC and press Enter.
