RUI_WRITE Is Rejected with Sense Code 0X'200D'

Article ID: 163021

Article Last Modified on 11/4/2003

APPLIES TO

This article was previously published under Q163021

SYMPTOMS

When an LUA application sends data while a BID response is pending, the RUI_WRITE request is rejected with Sense Code 0X'200D'

CAUSE

The LUA application is trying to send data while a BID response has not processed. This causes a race condition, and the RUI_WRITE is rejected.

RESOLUTION

A fix is available to correct this problem.

STATUS

Microsoft has confirmed this to be a problem in Microsoft SNA Server versions 2.11 Service Pack 1 and 3.0. 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 and 3.0 U.S. Service Packs.

MORE INFORMATION

The application is trying to send data immediately after a BID request has come in. The SNA Server service processed the data sent by the application instead of sending the BID response for the pending BID request. This causes a race condition in the SNA Server service, and the RUI_WRITE is rejected with the following Sense Code: 
   0X'200D' Response Owed Before Sending Request: An attempt has been made
            in half-duplex (flip-flop or contention) send/receive mode to
            send a normal-flow request when a response to a previously
            received request has not yet been sent.
With the SNA Application LUA API trace enabled, you may see the following:
