Assigning Specific LUs to TN3270 Users Doesn't Work Reliably

• Microsoft SNA Server, version 2.11 SP1
  on the following platforms: NT

SYMPTOMS

The SNA Server 2.11 Service Pack 1 (SP1) TN3270 Server service supports the TN3270E specification, which allows a specific LU to be requested by the TN3270E emulator.

In the TN3270 Administrator program, it is also possible to assign a specific LUA LU to a specific client TCP/IP address. However, if the TN3270E emulator does not request this specific LUA LU name, the user may receive another available LUA LU (if an LU is assigned to any IP address, or to the subnet mask of the user) and not the specific LU.

CAUSE

The SNA Server 2.11 SP1 TN3270E service was not designed to support LU-to-IP address assignment if the TN3270E emulator does not request this specific LU. Instead, this configuration would cause the TN3270E server to prevent other TN users from accessing this specific LU.

RESOLUTION

Reliable LU-to-IP address assignment has been added to the SNA Server 2.11 SP1 TN3270E server through an update available from Microsoft Product Support, for either TN3270 or TN3270E clients. This feature is also supported in SNA Server 3.0.

STATUS

This feature has been added to 2.11 and is available from Microsoft. Contact Microsoft Product Support Services for more information.
