Communications Setup and Scenarios for 3-Tier Communications Server

  Setting up the IBM Com Server as an MPTN Gateway
  Defining the Mode Name for DRDA Connections = IBMRDB
  Defining or Verifying the DB2 Transaction Program Name
  Setting up the IBM Communications Server in an IEEE 802.2 DLC Scenario

Setting up the IBM Com Server as an MPTN Gateway
1. Start the IBM Communications Server SNA Node Configuration application.
2. Select Scenarios on the menu bar, and then select AnyNet SNA over TCP/IP Gateway.
3. The left pane of this scenario window lists the steps. Double-click Step 1.
The Define the Node dialog box appears.
4. On the Basic tab, type the fully qualified CP name and the CP alias under Control Point. Accept the defaults for Block ID and Physical Unit ID.
5. Under Node Type, select Network Node.
The Advanced and DLU Requester tabs can be left with their current default values for this application.
6. Click the OK button to return to the Communications Server SNA Node Configuration dialog box.
The node setup appears in the right pane.
7. Double-click Step 2 - Configure SNA/IP gateway device.
The AnyNet SNA/IP device is auto-configured when the AnyNet gateway scenario is selected.
8. Double-click on the ANYNET device name in the right pane to show its properties
The Define an AnyNet SNA over TCP/IP Device dialog box appears.
9. Select the Basic tab to view the port name and the default SNA domain name suffix.
10. Verify that Gateway node is selected under AnyNet SNA over TCP/IP node type.
11. The SNA domain name suffix is concatenated onto the target luname.netid to map the dotted TCP/IP address to a netid.luname = APPN.CONNXDB2. To implement this mapping, add the following entries in the Windows server winnt\system32\drivers\etc\hosts file:
012.345.678.901 connxdb2 #=localhost
012.345.678.901 connxdb2.appn.sna.ibm.com #=localhost
where 012.345.678.901 is an example dotted IP address for the server machine. This entry is not needed in the hosts file if a symbolic entry is defined in your network domain name server.
12. Click the OK button to return to the Communications Server SNA Node Configuration dialog box.
