Hello,
I am able to read from, write to and browse queues on Remote Queue Managers using RFHUtil in Client mode. However, when I attempt to do something similar using a standalone Java program, it exits with the following return code -
| Quote: |
| MQJE001: Completion Code 2, Reason 2058 |
So I assume its the queue open options that aren't working. I'm currently using -
| Code: |
| MQC.MQOO_INPUT_AS_Q_DEF + MQC.MQOO_INQUIRE |
This works well for local queues.
I want to know the default options used by RFHUtil to do a read from a remote queue so that I can use the same in the Java program. Am I on the right path?? HELP!

| What part of the description of MQRC 2058, which is MQRC_Q_MGR_NAME_ERROR makes you think it is caused by the open options? |

Technically, you cannot read (get from) a remote queue, you can connect to a remote queue manager and access a local queue on that QM.
Are you sure you have used client mode and not binding mode to connect to MQ?

This is my readqueue method
| Code: |
public void readQ() {
MQQueueManager qMgr = null;
MQQueue queue = null;
String[] splits1 = queueManager.split("/");
String hostname = splits1[2].substring(0, splits1[2].indexOf("("));
String port = splits1[2].substring(splits1[2].indexOf("(") + 1, splits1[2].indexOf(")"));
String channel = splits1[0];
try {
Hashtable properties = new Hashtable();
properties.put(MQC.HOST_NAME_PROPERTY, hostname);
properties.put(MQC.PORT_PROPERTY, Integer.parseInt(port));
properties.put(MQC.CHANNEL_PROPERTY, channel);
properties.put(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_CLIENT);
qMgr = new MQQueueManager(this.queueManager, properties);
int openOptions = MQC.MQOO_INPUT_AS_Q_DEF + MQC.MQOO_INQUIRE;
queue = qMgr.accessQueue(this.queueName, openOptions, null, null, null);
String msgText = "";
MQMessage rcvMessage = new MQMessage();
queue.get(rcvMessage);
byte[] b = new byte[rcvMessage.getMessageLength()];
rcvMessage.readFully(b);
msgText = new String(b);
writeFile(this.fileName, msgText);
} catch (MQException ex) {
if (ex.reasonCode == 2033) {
System.out.println("No message on the specified queue: " + this.queueName);
} else {
System.out.println("A WebSphere MQ Error occured : Completion Code "
+ ex.completionCode
+ " Reason Code "
+ ex.reasonCode);
}
writeFile(this.fileName, "");
} catch (IOException ex) {
System.out.println("An IOException occured while reading to the message buffer: " + ex);
writeFile(this.fileName, "");
} catch (Exception ex) {
System.out.println("Some other exception!: " + ex);
writeFile(this.fileName, "");
} finally {
try {
queue.close();
qMgr.disconnect();
} catch (Exception e) {
System.out.println("Error in finally!");
}
}
} |
I supply the queuemanager name to the program in the following format
| Quote: |
| CHANNELNAME/PORTTYPE/HOSTNAME(PORT) |
zpat, yes sorry for that. What I really meant was connecting to a remote Queue Manager and performing operations on queues residing there.
mqjeff, well RFHUtil connects well in Client mode. So I knew it had to do something with my initial connection setup.

Try putting the new MQQueueManager into a separate try/catch from the accessQueue.
Then think, and review the documentation on MQRC 2058. |

Where do you set the queue manager name value?
Not just the connection data. |

zpat, its supplied to the program as a command-line param.
