Defining or Verifying the DB2 Transaction Program Name

1. Select Transaction Program in the CPI-C and APPC directory folder in the Communications Server SNA Node Configuration dialog box, and then click the Create button.

The list of defined transaction programs appears.

The default APPC transaction program for DRDA is 0x07F6C2C4 = .6DB.

Now you will define this program to your IBM Communications Server.

2. In the Basic tab, enter 076DB for the TP name.

3. Make sure that the Service TP checkbox is checked.

4. Select "Basic" for Conversation Type.

5. Select "Any" for Synchronization Type.

6. In the Advanced tab, enter 3600 in the Receive_Allocate timeout field.

7. Enter 30 in the Incoming allocate timeout field.

8. Enter 0 in the TP instance limit field.

9. Make sure the For SNA API Client use checkbox is checked.

10. Click Apply and OK.

11. From the Definition Hierarchy By Function pane, select Partner LU 6.2 LUs and click the Create button.

12. In the Basic tab, enter "APPN" and "CONNX400" in the respective Partner LU name fields.

13. Enter CONNX400 in the Partner LU alias field.

14. In the Fully qualified CP name section, select New and enter "APPN" and "CONNX400".

The MPTN mapping from TCP/IP address to an APPC netid.luname is implemented in the \winnt\system32\drivers\etc\hosts file, as follows:

012.345.678.012 connx400.appn.sna.ibm.com #Anynet

Thus, the SNA netid.luname is appn.connx400, which should match the Local Network ID and local control point name fields as displayed in the OS/400 DSPNETA command. The sna.ibm.com suffix is the default SNA domain name suffix defined by the IBM Communications Server AnyNet Gateway Scenario as shown in To set up the IBM Com Server as an MPTN Gateway. If this entry is not present in your Windows server hosts file, it must exist in a TCP/IP domain name server on your network. The dotted IP address is the address of the target OS/400 machine.
