We have MQ 5.3 Client Version installed on Solaris 8 and trying to verify the client installation using the C executable - amqsputc. The program starts up and just hangs. Verified that the MQSERVER has been set.
:/opt/mqm/samp/bin > ./amqsputc Q1 QMgr
Sample AMQSPUT0 start
:/opt/mqm/samp/bin
We are refering to this document - http://publibfp.boulder.ibm.com/epubs/pdf/amqdac04.pdfChapter 6. Verifying the client installation - Testing communication between the workstations.
We tested the connection from Java and it was fine. We were able to even push and pull messages. However, we need to have the C connection working.
Is there anything that we are missing ?
Thanks |

It's waiting for you to give it input... 
Type something, and hit enter. This will become the message.
Then hit enter again, to put in a blank line, and it should exit.

Jeff,
We have tried to enter messages and there has no response.
/opt/mqm/samp/bin )% ./amqsputc Q1 QMgr1
Sample AMQSPUT0 start
Testing1
^C
^C
/opt/mqm/samp/bin )%
Debugged the code and it just hangs on the MQCONN portion of the code.
QMName[0] = 0; /* default */
if (argc > 2)
strcpy(QMName, argv[2]);
MQCONN(QMName, /* queue manager */
&Hcon, /* connection handle */
&CompCode, /* completion code */
&CReason); /* reason code */
/* report reason and stop if it failed */
if (CompCode == MQCC_FAILED)
{
printf("MQCONN ended with reason code %d\n", CReason);
exit( (int)CReason );
}
Any ideas why it would fail at the MQCONN?
Thanks |

Ah, yes.
It should show you "target queue Q1"...
What did you set MQSERVER environment variable to, before running amqsputc?
Should be something vaguely like "export MQSERVER=MY.CHANNEL.NAME/TCP/MY.QMGR.HOSTNAME(MY.QMGR.PORT#)"

Yes. Thats what we set the MQSERVER as.
Do you think there are any other variables that needs to be set up or any libraries that are required that we are missing ?
I appreciate your help. |

It doesn't appear to be failing at the MQConn? Just ... waiting...?
It could be an issue either trying to look up the hostname given, or trying to look up the user you're running amqsputc as (at the remote side).

This piece of code is not consistent... Either QMName is variable or it is an array. But I don't see *QMName[0] or &QMName[0] as referring to the first byte in the string? (c is not my forte)...
As well you MAY NOT WANT to use strcpy because the QMName HAS to have a fixed length (48?) and I am not sure that a strcpy will preserve that...
Check out the Application Programing Guide and reference.
There should be examples there on how to correctly populate the qmgr's name with a string less than the max length...
And BTW my understanding is that the default is not a null string but spaces...
Enjoy

| Is a listener running on the MQ server? Can you successfully IP ping the server hostname or ipaddress? Can you telnet to the port? |
