  • Microsoft SNA Server for Windows NT, versions 2.0 2.1 and 2.11

SNA Server for Windows NT includes a APPC router for MS-DOS which supports the IBM PC Support/400 product. When loaded, IBM PC Support/400 users may access their AS/400 through SNA Server, using an SNA Server MS-DOS client. This article describes configuration changes to use IBM PC Support/400 through SNA Server.

MORE INFORMATION

To use IBM PC Support/400 through SNA Server, do the following:

Do the following from SNA Server Admin:

  1. Configure a connection to the AS/400 (see the SNA Server "Administration Guide" or Help for details on configuring a connection for each link service type).

  2. Add a Remote APPC LU to the connection:

    a. Highlight the connection and press Insert Select: APPC (Remote)

    b. Add Remote LU Properties LU Alias:

          Control Point Name of the AS/400 Network Name: AS/400 network name
          LU Name: same as LU Alias
          Uninterpreted LU Name: same as LU Name or blank
          Supports Parallel Sessions: Yes
          Enable Automatic Partnering: Yes/No (optional)
    

          Choose OK. (Partners will be set up later.)
    

  3. Add a Local APPC LU to the Server

    a. Highlight the Server (the computer name running SNA Server) and press

          Insert; in the New Logical Unit field, select APPC (Local).
    

    b. Add Properties:

          LU 6.2 Type: Independent
          LU Alias:  User name (or any unique LU name)
          Network Name: Same as network name on node definition for this server
    
             (usually APPN)
          LU Name: same as LU Alias
    
       c. Partners (select):
    
          Select Add and the select the correct Partner LU (created in step 2
          above) and partner with the "QPCSUPP" Mode (this is partnered by
          default), then select Close on the Partner dialog box and choose OK
          on the Properties dialog box.
    
       d. Save the new configuration and activate SNA Server and connection.
    
    
Do the following on the SNA Server client workstation:

  1. Install the SNA Server MS-DOS client software (run the SETUP program off the \\<server>\CLIENTS\MSDOS directory)

  2. Copy the SNA Server MS-DOS client ROUTER.EXE and INITRTR.EXE into your PCS directory.

  3. In the CONFIG.PCS file, change the Network.LUName on the RTLN line to match the Network.LUName configured at the server. The network name should match the network name of the server and the LUName should match the Local APPC LU name.

  4. Start SNABASE and ROUTER

Once they have started, you should be able to use IBM PC Support/400.

Also, per the SNA Server Installation Guide (p. 88), if you are running the real mode MS-DOS redirector provided with Windows for Workgroups or the Microsoft Network Client over the named pipes interface, your computer may stop responding (hang) unless you add the following entry to the [networks] section of SYSTEM.INI:

   maxcmds=10

and start the redirector using the "NET START FULL" command.

NOTE: IBM PC Support/400 runs on the SNA Server MS-DOS client. In order to use the Windows 3270 or 5250 applet included with SNA Server, you must load the SNA Server Windows client software. The SNA Server MS-DOS client software does not operate concurrently with the SNA Server Windows client software--only one can be loaded at one time.

  1. Using the Enhanced version of IBM PC Support

If you are using the Enhanced version of IBM PC Support (instead of the Basic version), the Enhanced functions will not be able to find the real- mode SNA Server MS-DOS router. To solve this, the RTRMAP.EXE utility must be downloaded from the AS/400 shared folders drive (by default, located in the I:\FL2 directory), copied to the client workstation and loaded after the ROUTER utility is loaded.

NOTE: There are known problems running the enhanced mode shared folders function over the real mode MS-DOS router. There is no solution for this problem, except to revert to the Basic version of PC Support, or to upgrade to IBM Client Access/400 and the SNA Server 2.11 Windows client software.

Please see the Microsoft SNA Server 2.1 Installation Guide, Chapter #3, pg. 82-89 for detailed instructions on installing and configuring the SNA Server MS-DOS router to support IBM PC Support, and for special considerations when running on a Windows or Windows for Workgroups client machine.
