TITLE   :SLI_OPEN May Fail With LUA_STATE_CHECK/LUA_NO_SLI_SESSION
PRODUCT :Microsoft SNA Server

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft SNA Server, versions 3.0, 3.0 SP1, 3.0 SP2, 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When using the SNA Server Win32 SLI API interface, an SLI application may
receive the following SLI_OPEN error when attempting to reopen a dependent
session:

   

  primary_rc   = 0x0002     (LUA_STATE_CHECK)
  secondary_rc = 0x00000034 (LUA_NO_SLI_SESSION)

The following API and message flow summarizes the behavior that may be observed
in SNA Server API and 3270 message traces:

SLI Program  SLI API   RUI API     SNA Server /Host
===========  =======   =======     =================
        <SLI program in session>

SLI_BID ->
SLI_SEND (send host logoff) ->
             <- SLI_SEND OK
                                   <- UNBIND
             <- SLI_BID (LUA_SESSION_FAILURE)
             RUI_TERM ->
                       <- RUI_TERM OK
SLI_OPEN ->
             <- SLI_OPEN ERROR: LUA_STATE_CHECK, LUA_NO_SLI_SESSION

CAUSE
=====

The SNA Server SLI interface was incorrectly locating an SLI control block based
on the LU name, which is not always unique. Instead, SLI should have been
checking the session ID which is always unique.


STATUS
======

Microsoft has confirmed this to be a problem in SNA Server 3.0, 3.0 Service Pack
1 (SP1), 3.0 SP2, and 4.0.

This problem was corrected in the latest SNA Server versions 3.0 and 4.0 U.S.
Service Packs. For information on obtaining these Service Packs, query on the
