Hi,
I would like to get list of process id's, what server connection channels they are using and from what ip they are connected to queue, by using the INQUIRE_Q_STATUS PCF command in Java.
The problem is that either the command returns single PCFMessage as answer to request, where all .getParameterValue() -method calls return null, or in some cases after few call's it returns "com.ibm.mq.MQException: MQJE001: Completion Code 2, Reason 2033" and crashes the amqpcsea process in WMQ queue manager (produces FDC file, WMQ have to be restarted after this so that it will work again).
I found similiar problem from the post "Having problems with INQUIRE_Q_STATUS using PCFMessageAgent (http://www.mqseries.net/phpBB2/viewtopic.php?t=11434)", but unfortunately that didn't solve my problem (example code in that post works OK altought).
The WMQ version is 530.10 CSD10 on Windows.
I attached the test code that I can use to re-produce the problem:
| Code: |
public static void main(String[] args) {
PCFMessageAgent agent = null;
try {
// Create INQUIRE_Q_STATUS PCF message
PCFMessage inquireQueueStatus = new PCFMessage(
CMQCFC.MQCMD_INQUIRE_Q_STATUS);
inquireQueueStatus.addParameter(CMQC.MQCA_Q_NAME, "TEST.LQ");
inquireQueueStatus.addParameter(CMQCFC.MQIACF_Q_STATUS_TYPE,
CMQCFC.MQIACF_Q_HANDLE);
// Connect to qmgr
agent = new PCFMessageAgent();
agent.connect("BROKER_QM");
// Send the INQUIRE_Q_STATUS PCF request
PCFMessage response[] = agent.send(inquireQueueStatus);
// Print the INQUIRE_Q_STATUS PCF response(s)
for (int i = 0; i < response.length; i++) {
String queueName = (String) response[i]
.getParameterValue(CMQC.MQCA_Q_NAME);
String channelName = (String) response[i]
.getParameterValue(CMQCFC.MQCACH_CHANNEL_NAME);
String connectionName = (String) response[i]
.getParameterValue(CMQCFC.MQCACH_CONNECTION_NAME);
System.out.println(queueName + ", " + channelName + ", "
+ connectionName);
}
} catch (Exception e) {
e.printStackTrace();
} finally {
if (agent != null) {
try {
agent.disconnect();
} catch (MQException ignored) {
}
}
}
} |
I appreciate your help,

| You might need APAR IY69886 qv. |

That was good tip.
Adding the QStatusAttrs -code line fixed the problem,
| Code: |
// Fixed & working code
inquireQueueStatus.addParameter(CMQC.MQCA_Q_NAME, "TEST.LQ");
inquireQueueStatus.addParameter(CMQCFC.MQIACF_Q_STATUS_TYPE,
CMQCFC.MQIACF_Q_HANDLE);
inquireQueueStatus.addParameter(CMQCFC.MQIACF_Q_ATTRS,
new int[] { CMQCFC.MQIACF_ALL }); |
It seems that also the parameter order matters, I first added the MQIACF_Q_ATTRS before the MQIACF_Q_STATUS_TYPE, and it then returned the QName, but not the ChannelName or ConnName(returned only null). After I corrected order it now returns also the ChannelName and ConnName.
Thanks Nigel for your help ! |
