I am sending a message to a CICS bridge from a C# program. The CICS program receives the message correctly and then sends a response back to me. When I do a MQGET from my .NET assembly, I get a 2110 error. Here is a snippet of the function that is doing the get. Does anyone have any ideas on what I am doing wrong?
private string getMessage(string replyQueueManager, string replyQueueName)
{
MQQueueManager mqQManagerReply = null;
MQQueue mqQueueReply = null;
try
{
// Getting the Response
mqQManagerReply = new MQQueueManager(replyQueueManager, ConnectOptions);
mqQueueReply = mqQManagerReply.AccessQueue(replyQueueName,MQC.MQOO_INPUT_SHARED|MQC.MQOO_BROWSE);
MQGetMessageOptions mqGMO = new MQGetMessageOptions();
mqGMO.Version = MQC.MQGMO_VERSION_3;
mqGMO.MatchOptions = MQC.MQMO_MATCH_MSG_ID; //needs to revisit as Message ID is for MQMD only
mqGMO.Options = MQC.MQGMO_WAIT | MQC.MQGMO_NO_SYNCPOINT | MQC.MQGMO_CONVERT;
mqGMO.WaitInterval = Convert.ToInt32(waitInterval); // needs to get from Configuration
MQMessage mqMessageReply = new MQMessage();
mqMessageReply.MessageId = messageIDPut;
mqMessageReply.CharacterSet = int.Parse(charSet); string replyMessage = null;
while (true)
{
mqQueueReply.Get(mqMessageReply, mqGMO);
replyMessage += mqMessageReply.ReadString(mqMessageReply.DataLength);
string endIndicator = EbcdicToAscii(mqMessageReply.CorrelationId);
endIndicator = endIndicator.Substring(1,4);
if(endIndicator != "MORE" || (mqMessageReply.CompletionCode!= 0 & mqMessageReply.CompletionCode!= 1 & mqMessageReply.ReasonCode != 2080))
{
break;
}
}
if (mqQueueReply !=null && mqQueueReply.IsOpen)
mqQueueReply.Close();
if (mqQManagerReply !=null && mqQManagerReply.IsConnected)
mqQManagerReply.Disconnect();
return replyMessage; |

Do you know if the CICS program is setting the mqmd.Format to "MQSTR"?

I hope it's setting it to "MQSTR<space>". Or really to MQFMT_STRING.

| I do not know. I will ask my mainframe developer. |

Are you using the MQ-CICS bridge supplying an MQCIH on input (and expecting one on return)?
If so you need to specify the Convert=yes attribute on the channel definition for the channel from the mainframe to your box.
The reason is that the format conversion routines for the CIH only exist on the mainframe and a windows queue manager does not recognise the format.

| I am supplying an MQCIH on input and expecting one back. Our environment is a little different. We are not allowed to make client connections with the mainframe. We are forced to send the message through a UNIX server and then to the mainframe. When the CICS program returns the response is passed from the mainframe back through the UNIX box to our Windows server. |

You cannot do an MQGET with CONVERT on a msg with Format MQCICS, you will get the 2110 (MQRC_FORMAT_ERROR) returned to the MQGET.
The MQCICS format is not recognised (for conversion) on distributed platforms, only on host systems. This is documented in the APR, Appendix D, Data Conversion.
