TN3270 User Session Is Lost Unexpectedly (138858)
The information in this article applies to:
- Microsoft SNA Server 2.11, when used with:
- the operating system: Microsoft Windows NT
This article was previously published under Q138858 SYMPTOMS
When you use a TN3270 client program through the SNA Server 2.11 TN3270
Server service:
- A TN3270 user session may be lost unexpectedly.
- A TN3270 file transfer upload request may appear to be hung, though
the TN3270 display session may have been reset to the initial host
signon screen.
- A TN3270 client emulator may fail to get a session through the
TN3270 server.
CAUSE
The TN3270 server incorrectly requests definite response during a chain,
even though exception response was requested by the TN3270 client
application. The TN3270 server then receives the following error from the
SNA Server LUA API interface:
prim_rc=0x1400 (LUA_UNSUCCESSFUL)
sec_rc=0x00000740 (LUA_DEFINITE_RSP_NOT_ALLOWED)
This causes the session to be reset.
RESOLUTION
To correct this problem, install the fix mentioned below. When exception
response protocol is being used, the TN3270 server now properly sets the
Definite Response indicator only when the End Chain (EC) is set.
STATUS
Microsoft has confirmed this to be a problem in SNA Server for Windows NT.
This problem was corrected in the latest SNA Server for Windows NT, 2.11
U.S. Service Pack. For information on obtaining the Service Pack, query on
