Environment: Solaris 10 with MQ client libraries

Iâ€™ve got no access to runmqsc as we only have a client installation. Does anyone know whether itâ€™s possible to write C++ code linked with the MQ client libraries which can list all queues in a queue manager?

Regards

Check out the manuals there is something about PCF (Programmable Command Format) messages...

You can also use MO72 support pack (client form of mqsc)...

Enjoy

Thanks for pointing me in the right direction. The MQ sample program amqsailq.c lists all queues and queue depths. Ideally I want a C++ API rather than a C API but it looks like Iâ€™ve got a potential solution.

The C++ code fragment that gives the queue depth of a named queue is as follows. You wouldnâ€™t know whether there is a C++ API for listing all queues in a queue manager do you?

x-------------------------------------------------x
ImqQueueManager manager;
manager.setName(queueMgr.data());
if ( manager.connect() ) {
ImqString strQueueManagerName(manager.name());
cout << "Connected successfully to queue manager: <"
<< strQueueManagerName << ">" << endl;
ImqQueue *pqueue = new ImqQueue;
pqueue->setConnectionReference(manager);
pqueue->setName(queue.data());
MQLONG qdepth;
pqueue->currentDepth(qdepth);
if (qdepth < 0 ) {
cerr << prog << ": Fatal error. Please specify a valid queue"
<< endl;
returnCode = -1;
}
cout << "Depth of MQ queue: <" << pqueue->name() << "> is <"
<< qdepth << ">" << endl;
} else {
cerr << prog
<< ": ** Fatal. Connection failure to specified queue manager**"
<< endl;
cerr << "** ImqQueueManager::connect failed with reason code:" << manag
er.reasonCode() << endl;
returnCode = (int)manager.reasonCode();

}
}
catch ( std::string& error )
{
cerr << endl
<< "ERROR :: "
x-------------------------------------------------x

ebizqdepth $MQ_QUEUE_MANAGER $MQ_INBOUND_Q
Connected successfully to queue manager: <XXX.YYY.EBIZ.DEV>
Depth of MQ queue: <MA3.SR.CPY.OF.SWIFT.INBOUND> is <0>
