Hi,
I am facing a problem with the client error code 2010.
OS: windows 2000 server with service pack 4
MQ : version 5.2.1
I am using same m/c as MQ server and client. Client code in C/C++ . I have declared MQMD and MQPMO option is default. I am Using server connection channel and its maxmsgl attribute values is 50MB. Both Queue and QueueManager maxmsgl is 80MB. I am trying to put 20 MB file size data. Getting client error code 2010 and error in server log is AMQ 9208.
There is no problem of transferring 4MB data.
I am not using MQSERVER environment variable.
Can anybody please help to solve this problem.
Thanks in Advance.

It looks like channel message size problem. Double check that you are using the right message channel.
May be you have multiple definitions in a channel table ?
Check what CCSID you use (Unicode maybe ?). Try increasing to maximum 100 MB size.

Hi,
Server connection channel name is correct. (using default. SYSTEM.DEF.SVRCONN). Channel size is 50 MB which is more than enough for transfer 20 MB data.
Thing is I have changed the MAXMSGL attribut eto 50 MB from 4MB. Will it create multiple definition in CHLTAB?. In that case how to trace or to specify to take latest definition?.
I haven't specified anything in CCSID field. But while 2010 problem, the CCSID field in MQMD seems to tbe the value '0'. What correct value and where I have to specify for this?.
The last thing, I have tried from java program. It is working perfectly. Only thing is i have given the option java -Xms to 200MB. And also i have increased the MQ primary and secondary log file size to enough.
In java i am using the same Channel (SYSTEM.DEF.SVRCONN).(client mode connection).
-----------------------------------------------------------------
The following code i am using in my C/C++
MQMD md = {MQMD_DEFAULT}; // Message Descriptor
MQPMO pmo = {MQPMO_DEFAULT}; // put message options
MQLONG CompCode; // completion code
MQLONG Reason; // reason code
MQLONG BCompCode;
MQLONG BReason;
MQLONG messlen = len; // message length
PMQVOID mqpv=NULL;
mqpv=chpmsg;
//md.Version = MQMD_VERSION_2;
try
{
if (len >0)
{
//pmo.Options = MQPMO_SYNCPOINT | MQPMO_FAIL_IF_QUIESCING | MQPMO_NEW_MSG_ID ; // Put Message Option
pmo.Options =MQPMO_FAIL_IF_QUIESCING ;
// character string format
//memcpy(md.Format, MQFMT_STRING, ((size_t)MQ_FORMAT_LENGTH));
MQPUT(_hcon, // connection handle
m_Putobj, // object handle
&md, // message descriptor
&pmo, // default options (datagram)
messlen, // message length
mqpv,// unsigned char pointer message buffer
&CompCode, // completion code
&Reason); // reason code
-----------------------------------------------------------------
My doubt is I am using VC++ compiler for running this pgm. Any memory restriction is there for unsigned char * variable?. Because in my above code, unsigned char pointter variable is holding data.
Even If I am tring to put 4MB+1 byte data, it is failing with the error code 2010.
Error from server log is
-------------------------------------------------------
AMQ9208: Error on receive from host satyamqp (172.24.8.45).
EXPLANATION:
An error occurred receiving data from pandianhost (172.24.8.45) over TCP/IP. This
may be due to a communications failure.
ACTION:
The return code from the TCP/IP (recv) call was 10054 (X'2746'). Record these
values and tell the systems administrator.
---------------------------------------------------------------
Thanks for any reply.

Havent come accross this earlier, but here's what is in than manuals.
2010 X'07DA' MQRC_DATA_LENGTH_ERROR
The DataLength parameter is not valid. Either the parameter pointer is not valid, or it points to read-only storage. (It is not always possible to detect parameter pointers that are not valid; if not detected, unpredictable results occur.)
This reason can also be returned to an MQ client program on the MQGET , MQPUT , or MQPUT1 call, if the BufferLength parameter exceeds the maximum message size that was negotiated for the client channel.
Corrective action: Correct the parameter.
If the error occurs for a WebSphere MQ client program, also check that the maximum message size for the channel is big enough to accommodate the message being sent; if it is not big enough, increase the maximum message size for the channel.
Might help track the problem.
By the way, can you post your java app code here as well. Just was curious to see if there were any differences.
But it sure sounds like the size did upset the channel.
Cheers

Hi Kumrar,
Thanks for reply. But already I saw error description from ibm docs. Afterthat only I have changed channel maxmsgl attribute.
And also error description 'DataLength parameter is not valid...Either the parameter pointer is not valid......' , I couldn't understand this one. If pointer is invalid means, it should throw error while transfer < 4MB data . But there is no problem of transferring <= 4MB data. But problem arise evern if i transfer 4MB+1 byte data. So any special configuration or special option to be set in program for C/C++ code?.

Well, since you "say" that it works using Java app and fails with C++ apps, i wouldnt really go into the configuration part, at least initially. And would compare the 2 sources instead and figure out whats different. Thats the very reason i asked you to post your java code as well.
Cheers

Once again I am remainding that no problem still putting <=4mB data. |

Hi,
for your C/C++ programs you have do define a client-connection channel with the same name as your server-connection channel and set the appropriate max message length.
The client-connection channel definition is written to the AMQCLCHL.TAB file not the server-connection channel.
As an alternative you can use a MQCONNX call in your c-code
to define your client-connection channel at runtime like the java programs do.

Hi,
I am getting totally confused . If you see my C++ code, already i am using MQCONNX mode.
My client program & server program is running in the same m/c.
Clear my following doubts.
1. Is it must to define client connection channel for c++ code?.
2. Any special option to be set in MQCONNX call?. if so, what it is?.
In that case , why it is not throwing error while transfering <=4MB data.

A connection in CONNX mode does nothing special unless you are supplying an MQCD. If you are supplying an MQCD (clientconnoffset/clinetconnptr), then you need to increase the MQCD.MaxMsgLength field prior to the connect.
Changing the svrconn is also required, but I believe this value is negotiated, and the MQCD default is 4mb - ie if one side (svrconn) says 50mb but the clientconn (MQCD) says 4mb, we only allow 4mb). |
