Dynamically Defined Dependent LU Support for LUA LUs

ID: Q164592

The information in this article applies to:

Microsoft SNA Server, versions 2.11, 2.11 SP1, 3.0

SYMPTOMS

Microsoft SNA Server versions 2.11 and later provide support for Dynamically Defined Dependent LUs (DDDLU) for 3270 LUs. However, DDDLU support for LUA LUs is not provided in SNA Server.

For additional information on support for DDDLUs in Microsoft SNA Server, please see the following article in the Microsoft Knowledge Base:

Q161492 LU Session Activation Using Dynamically Defined Dependent LUs

CAUSE

When DDDLU support was originally added to SNA Server, DDDLU support was only implemented for 3270 LUs.

RESOLUTION

An update to SNA Server 3.0 is available. It provides DDDLU support for LUA LUs. By default, DDDLU support for LUA LUs is disabled. To enable this support, the following registry entry must be set to specify the Model Number to be requested by SNA Server when an LUA LU is dynamically activated.


   HKEY_LOCAL_MACHINE
      \SYSTEM
         \CurrentControlSet
            \Services
               \SnaServr
                  \Parameters
                     \LUADDDLUModel:REGDWORD: <Model Number>

Model Number can be 1 through 5 to correspond to supported 3270 Model Numbers.

The following files were updated to add this support:

<snaroot>\system\snaservr.exe
<snaroot>\system\trcservr.exe (used for debugging purposes only)

STATUS

Microsoft has confirmed this to be a problem in SNA Server versions 2.11, 2.11 SP1, and 3.0. This problem was corrected in the latest Microsoft SNA Server 3.0 U.S. Service Pack.
