| We create a list of dynamic queues using Date and Business Type as part of the queue name, such as CLK.G2B.PHY.DEVL.ISS.20040216CCS* . When dynamic queues are processed, they are deleted. But if the process fail for whatever reason, how could we use the java inquire method to get a list of the names of the queues left over? it will be very helpful if some code can be providied provided. |

| Go look at SupportPac MS0B (java PCFs) and check out the sample program ListQueueNames.java. This program uses PCF messages to get a list of queue names. |

Yes, but PCF doesn't work if you need a list o queues from host.
I learned it kicking my head against the 3001 code error |

Hi,
If by "host" you mean OS/390 or z/OS then true, you cannot use PCF. You need to send "Plain Text" commands to the command server.

A snippet of code is more powerful of hundreds posts  :
[...]
int openOptions = MQC.MQOO_OUTPUT;
MQMessage message = new MQMessage();
MQQueueManager mqqm = new MQQueueManager("<YOUR_QMANAGER>");
String commandQueue = mqqm.getCommandInputQueueName();
String replyQueue = "SYSTEM.DEFAULT.LOCAL.QUEUE";
/* This is the core part of the code
| Quote: |
| You need to send "Plain Text" commands to the command server. |
*/
String command = "DISPLAY QUEUE(*) ALL";
MQQueue q = mqqm.accessQueue(commandQueue,openOptions);
message.replyToQueueName = replyQueue;
message.messageType = MQC.MQMT_REQUEST;
message.format = MQC.MQFMT_STRING;
byte[] b = command.getBytes();
message.write(b);
MQPutMessageOptions pmo = new MQPutMessageOptions();
message.messageId = MQC.MQMI_NONE;
q.put(message , pmo);
byte[] messageID = message.messageId;
q.close();
openOptions = MQC.MQOO_INPUT_AS_Q_DEF;
MQQueue rq = mqqm.accessQueue(replyQueue,openOptions);
/*
* this method retrieves response messages from reply queue,
* it uses the messageId to match the correlationId of the response
* messages
*/
ret = getCmqMessages(rq, message.messageId);
