This code reproduces the issue:
| Code: |
#include <iostream>
#include <xms.hpp>
int main()
{
try
{
xms::ConnectionFactory factory;
factory.setIntProperty(XMSC_CONNECTION_TYPE, XMSC_CT_WMQ);
factory.setIntProperty(XMSC_WMQ_CONNECTION_MODE, XMSC_WMQ_CM_CLIENT);
factory.setStringProperty(XMSC_WMQ_QUEUE_MANAGER, "devpmmq.queue.manager");
factory.setStringProperty(XMSC_WMQ_HOST_NAME, "devpmmq");
factory.setStringProperty(XMSC_WMQ_CHANNEL, "SYSTEM.DEF.SVRCONN");
factory.setIntProperty(XMSC_WMQ_PORT, 1414);
std::cout << "Is Factory Null? => " << factory.isNull() << std::endl;
xms::Connection conn = factory.createConnection(); //THIS THROWS EXCEPTION
std::cout << "Is Factory Null? => " << factory.isNull() << std::endl;
}
catch(xms::Exception const & e)
{
e.dump(std::cout);
}
}
|
It throws exception, dumping the following message:
| Quote: |
Is Factory Null? => 0
Exception:
ErrorData =
ErrorCode = 26 (XMS_E_CONNECT_FAILED)
JMS Type = 1 (XMS_X_GENERAL_EXCEPTION)
Linked Exception:
ErrorData = libmqic_r.so
ErrorCode = 0 (XMS_E_NONE)
JMS Type = 1 (XMS_X_GENERAL_EXCEPTION) |
Any idea what is wrong with the code?
Note that `devpmmq` is just an alias to the actual IP address (host). If I put *any* random/nonsense value for it, I get the same error, which is bad because the API should have given a better error message such as *"host not found"* or something alone that line. Is there any way to enable *more* verbose diagnostics?

May i ask if you are trying the connection from a unix 64 bit operating system ?
In this case probably you don't have the correct libraries with the 64 bit
support on your mq installation ,so xms throw the exception ... |

Did you install the MQ client libraries on that server?

3 comments:
- Do not hard-code connection information in your application
- IBM's MQ Best Practices is to use uppercase for MQ object names (queue manager, queues, channels, etc.)
- Do NOT use SYSTEM objects like SYSTEM.DEF.SVRCONN channel.
