[ofw] ***SPAM*** SDP and Ethernet

[Tzachi Dar]

Hi,
 
As far as I can tell from a first look, it seems that there is some
problem in the configuration that you are using.
On the first look it seems that the problem might be that you have
removed the ibsdp provider and failed to install it again.
 
You can install it again using the command: InstallSdpProvider -i
 
The main idea when running with the parameter WSA_FLAG_OVERLAPPED | 0x40
is to tell the sdp layer to use SDP, but this  parameter is later
removed by the ibsdp.dll. I believe that if you get the 10022 error this
means that the ibsdp layer is not installed.
 
Am I right in assuming that even a simple program doesn't work for you
when you are trying to use mixed SDP applications?
 
In order to work with mixed SDP applications please make sure that:
1) SDP driver is running. (net start SDP)
2) The provider is installed. (InstallSdpProvider -i)
3) Set the registry value MIXED_SDP_APPLICATIONS to 1. It is located
under:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\sdp\Parameters
4) Make sure that the SdpApplications is *NOT* set to the name of your
application.
 
Here are also a few questions in order to try and understand your
environment:
1) Is my SQL running on windows, or is it running on Linux?
2) mysql_real_connect command, what is it exactly? Is this an
executable? Is this a function/library in the same program that you are
trying to run?
 
If my advice doesn't help can you please give me a remote connection to
your system?
If giving a remote connection is not possibale can you send me the
application that you are using? I believe that you have a simpler
version of this application.
 
I can also send you a debug version that will have more prints.
 
Thanks
Tzachi

	Hello,
	 
	We are developing an application (Audio & Video Server) in
Windows XP that use a MySQL database and SDP (socket direct protocol)
to transfer files from one machine to another through an mellanox
infinihost III. For us is mandatory to use SDP (Socket Direct Protocol)
because we need the fastest speed possible to transfer big video files.
We are using MLNX_WinOF for x86 plataforms version 1.1.0 MSI. We did the
transfer using sockets in a way similar to the SDK sample application
SdpConnect. We turn on SDP following instructions given in the document
"MLNX_WinOF_Readme.txt" in the topic "9.3 Running Applications over
SDP". Our application transfer files using SDP properly. The problem is
that we need also connect to a MySQL database in the same application.
We did this using the command "mysql_real_connect", but this command
failed when SDP Layer is on. When we turn off SDP layer the command
"mysql_real_connect" is successfull. We noted that MySQL uses socket
internally. So we need SDP sockets for our transfer routines and normal
sockets for access MySQL. Then we tried to use MIXED_SDP_APPLICATIONS
following the instructions given in the topic "9.4 Running an
Application over SDP and Ethernet" but did not work. This topic tells to
use :

	WSASocket (AF_INET_FAMILY, SOCK_STREAM,
IPPROTO_TCP,0,0,WSA_FLAG_OVERLAPPED | 0x40)

	for SDP sockets. We did it, but always can not create the socket
- error 10022. Taking a looking in the definition of WSASocket we
discover that the last parameter "flags" does not have the option
"WSA_FLAG_OVERLAPPED | 0x40".  As I understand the code 0x40 tells that
this socket is SDP but we can not use it because the command WSASocket
always fail because it does not understand this last parameter.

	How to solve this problem ? We need to use MySQL and SDP in the
same application.

	Can you send me more documents describing how to run an
Application over SDP and Ethernet ?

	Why I did not get to create the socket with WSA_FLAG_OVERLAPPED
| 0x40 ? What is missing ?

	Regards,

	Carlos Cunha
