INTRODUCTION
This article describes how to set up the connection and the logical units (LU) for an Advanced Program-to-Program (APPC) application. This article describes how to do this when you use the &quot;IP data link connection&quot; (IP-DLC) link service in Microsoft Host Integration Server 2006 together with dependent APPC logical units.



MORE INFORMATION
Consider the following scenario:
 * You use the IP-DLC link service to create a connection.
 * To do this, you use a remote end that is configured to use a host system.
 * Then, you configure a remote logical unit for the APPC application.

In this scenario, no connections are listed in the Connections list in the Remote APPC LU Properties dialog box.

When you use the IP-DLC link service to establish a connection between an APPC application and a mainframe computer, you must have two connections if you are using dependent APPC logical units. You must have a peer-system connection and a host-system connection.

When you use the IP-DLC link service to establish a connection to a mainframe computer that uses independent APPC logical units, you must use a peer-system connection to associate the remote logical units with the independent APPC logical units. In addition, local independent APPC logical units have no association with the host-system connection or with the peer-system connection.

Note The dependent local APPC logical units have to be defined on a host-system connection. The dependent local APPC logical units cannot be defined on a peer-system connection. Peer-system connections do not represent a physical link to a remote node. The peer-system connection represents a logical connection between the PU2.1 core Microsoft Host Integration Server node and the IP-DLC link service. This logical peer-system connection is required by the LU 6.2 protocol.

Step 1: Create the peer-system connection
Use one of the following methods to create the peer-system connection.

Important You must create the peer-system connection before you create the host-system connection.

Method 1: Create the peer-system connection manually
For more information about how to create the peer-system connection manually, visit the following Microsoft Developer Network (MSDN) Web sites:  &quot;How to create a local APPC LU&quot;

Method 2: Create the peer-system connection by using the Mainframe APPC/LU6.2 Wizard

 * 1) Click Start, click All Programs, click Microsoft Host Integration Server 2006, and then click SNA Manager.
 * 2) Expand Microsoft SNA Manager, expand Servers, expand the server name, right-click SNA Service, click All Tasks, and then click Mainframe APPC/LU6.2 Wizard.
 * 3) On the Welcome page, click Next.
 * 4) Click Third-party or custom APPC application, and then click Next.
 * 5) Select the host environment type that you want to use, and then click Next.
 * 6) In the Select the SNA Service to configure list, select the server that you want to use, and then click Next.
 * 7) Select an existing connection or a new connection, and then click Next.
 * 8) On the Worksheet page, click Worksheets to view the worksheets. When you finish viewing the worksheets, click Next.
 * 9) In the Local LU name box, type the local logical unit name, and then click Next.
 * 10) On the SyncPoint Support page, click Next.
 * 11) In the Remote LU name text box, type the remote logical unit name, and then click Next.
 * 12) On the Mode page, select an existing mode or new mode, and then click Next.
 * 13) Click Finish.

Step 2: Create the host-system connection
Use one of the following methods to create the host-system connection.

Method 1: Create the host-system connection manually
For more information about how to create the host system connection manually, visit the following MSDN Web site:

http://msdn2.microsoft.com/en-us/library/aa771047.aspx

Method 2: Create the host-system connection by using the 3270 Emulation Configuration Wizard
 Click Start, click All Programs, click Microsoft Host Integration Server 2006, and then click SNA Manager. Expand Microsoft SNA Manager, expand Servers, expand the server name, right-click SNA Service, click All Tasks, and then click 3270 Wizard. On the Welcome page, click Next. Select the server that you want to use, and then click Next.</li> In the Name box, type the name of the connection, and then click Next.</li> Select the link service that the connection will use, and then click Next.</li> Type the local node ID information in the following boxes:  IDBLK</li> IDNUM</li> Network Name</li> Control Point</li></ul>

Then, click Next.</li> In the PU address (PUADDR) box, enter the physical unit (PU) address, and then click Next.</li> On the Creating LUs page, enter the logical unit information.

Note You can change default name of the base logical unit, the starting logical unit number, and the number of logical units that you want to create. Click Next when you are finished.</li> Add the users or the groups that require mainframe user rights. Add these users to the Added members list, and then click Next.</li> Click Finish to create the connection.</li></ol>
