We are using .NET library of the IBM WebSphere MQ Client, Version 5.3 to send messages to the MQ on the mainframe (IMS). We are sending over 10,000 messages and most having no problems but only a few messages got additional white spaces added at the end. The only pattern we can see is that these messages are longer (296 characters) then the typical messages. Do you have any ideas?
| Code: |
protected void SendMQMessage(string messageText, string queueName,
string queueMgrName, string channelName, int port, string mqServerName)
{
MQQueueManager queueManager = null;
MQQueue queue = null;
try
{
MQEnvironment.Channel = channelName;
MQEnvironment.Port = port;
MQEnvironment.Hostname = mqServerName;
queueManager = new MQQueueManager(queueMgrName);
MQMessage message = new MQMessage();
MQPutMessageOptions pmo = new MQPutMessageOptions();
pmo.Options = MQC.MQPMO_NONE;
message.Format = MQC.MQFMT_STRING;
message.WriteString(messageText);
queue = queueManager.AccessQueue(queueName, MQC.MQOO_OUTPUT);
queue.Put(message, pmo);
}
catch(Exception ex)
{
Log.Error("MQQueueManager::Put failed", ex);
throw ex;
}
finally
{
if (queueManager != null)
{
queueManager.Disconnect();
queueManager = null;
}
}

MQ won't do this.
Where are you seeing the additional data. I'd take a look at the application that "thinks" there is.
Cheers,

I used the message browser and I see the data length is not what I expected. I tested using MQ on Windows and I also see this. |

Which message browser?
amqsbcg?
How are you sure that the extra characters are not in the "messageText" variable that you are writing to the message?

Originally, I thought this is a mainframe issue, so I decided to try and send a message to another windows box and I get the same problem.
I check the message length (295) before I send and I see the data length on the queue to be 590, which is double the actual message. I also tried to send the message like "abc" and the datalength is 6.
If you are on windows, then you click on the queue name then you can browse the message and that is what I mean message browser. |

OH.
So you mean you're sending Unicode text, and expecting it to be ASCII.

You are sending Unicode.
You are then looking at it as if it was ASCII, and being surprised that you are seeing double byte characters.

You are right I see the character set id is 1200, which unicode.
I need to set it to 437 instead and it fixes the problem.
Thank you for your help |
