TP_STARTED Stops Responding if NT App Opens More Than 256 TP (170776)
The information in this article applies to:
- Microsoft SNA Server 2.11
- Microsoft SNA Server 3.0
This article was previously published under Q170776 SYMPTOMS
After opening more than 256 transaction programs from a single Windows NT
application, a TP_STARTED request may stop responding.
CAUSE
The internal APPC callback function for the get_server_list and
get_default_lu's remote procedure calls (RPCs) assume that SNADMOD will
return only an eight-bit TP control block index. However, if the
application has already opened more than 256 transaction programs, the
SNADMOD could return a larger value, causing the APPC interface to fail to
respond to the TP_STARTED request.
STATUS
Microsoft has confirmed this to be a problem in SNA Server versions 2.11
and 3.0. This problem was corrected in the latest SNA Server version 3.0
U.S. Service Pack. For information on obtaining this Service Pack, query
