hi,
i'm writing a C# application which sends a PCF message to a command input queue and the response is directed to a named local queue of a queue manager. When I send the command, the queue manager is successfully processing it and putting the response in the ReplyToQ as expected.
how do I read this PCF response message in an understandable manner?
Does any one have a code example for it?
websphere mq v7.0.1.3
windows 2003
i tried searching first in this forum, but did not find any post related to it.
if this is a duplicate, i apologize and request any one to reply with a link.

Hi,
You should read the WMQ Programmable Command Formats and Administration Interface manual for information on how to handle PCF reply messages. To my knowledge, IBM has not created a PCFMessage class in C#.

hi Roger,
thanks for your response. We do have PCFMessage class in c# (amqmdnet.dll).
Let me check out the document you refered. Thanks again!

PCF classes in MQ .NET are undocumented. However people still use them.
Here is one sample I wrote.
try
{
PCFMessageAgent agent;
MQQueueManager qm = new MQQueueManager("MQQM");
agent = new PCFMessageAgent(qm);
PCFMessage request = new PCFMessage(CMQCFC.MQCMD_INQUIRE_Q);
request.AddParameter(MQC.MQCA_Q_NAME, "TESTQ");
request.AddParameter(CMQCFC.MQIACF_Q_ATTRS, new int[]{MQC.MQCA_Q_NAME, MQC.MQIA_Q_TYPE, MQC.MQCA_Q_DESC}); ;
PCFMessage[] responses = agent.Send(request);
for (int i = 0; i < responses.Length; i++)
{
PCFMessage response = responses[i];
PCFParameter[] param = response.GetParameters();
foreach (PCFParameter p in param)
{
Console.WriteLine(p.Parameter);
Console.WriteLine(p.GetValue());
}
}
}
catch (MQException mqe)
{
Console.Write(mqe);
} |

hi shashi,
thanks for your response. my bad and am sorry that I did not post my question properly. I'm rephrasing it here again.
I have created a MQ command message using the MQMessage class. I do not want to use the PCFMessage class to read the response message. I want to read it using the normal MQMessage class. In this MQMessage message properties, I've set the reply to queue name.
When I send this message to the command queue, the command server is successfully processing this message and also putting the response to the specified reply to queue.
Now, I want to read this response message, which is in the specified reply to queue. I know that the message is in PCF format in the queue, but I'm not sure how to read this message 
Thanks,
Manoj |
