I have a cluster (TEST) which has 3 QMgrs QMA,QMB,QMC.
QMB is the full repository and i have a local Q L1 on QMC that is shared in the cluster
Now, logically my java application should be able to put a message to L1 by connecting to QMA even though L1 physically resides on QMC.
However, while running the java application ( ie connecting it to QMA and putting to L1 ),I get a 2085 error. i.e Object unknown.
The java code is as below
| Code: |
import java.util.*;
import java.io.*;
import com.ibm.mq.*;
public class MQSeriesClientput {
static String HostName = "x.x.x.x";
private static String qmanager = "QMA";
private static String qchannel = "SYSTEM.DEF.SVRCONN";
private static String qname = "L1";
public static void main(String[] args){
//Step 1. Connect Application to the Queue Manager
try {
MQEnvironment env = new MQEnvironment();
env.hostname = HostName; // Could have put the hostname & channel
env.channel = qchannel; // string directly here!
env.port = 1000;
MQQueueManager qmgr = new MQQueueManager(qmanager);
int openOptions = MQC.MQOO_OUTPUT |MQC.MQOO_BIND_ON_OPEN ;
//Step 2. Open a Queue for output
MQQueue myq = qmgr.accessQueue( qname,
openOptions,
qmanager,
null,
null );
//Step 3. Put message into the queue
MQMessage mymsg = new MQMessage();
mymsg.messageId = null;
mymsg.correlationId = null;
mymsg.format = MQC.MQFMT_STRING;
String sendToMQ = "Test Message!";
mymsg.writeString( sendToMQ );
myq.put(mymsg);
System.out.println("Your job has been submitted ..."+"\n");
//Step 4. Close the Queue
myq.close();
//Step 5. Disconnect the Queue
qmgr.disconnect();
} catch(MQException mx) {
System.out.println( mx);
mx.printStackTrace();}
catch(IOException Ix) {
System.out.println( Ix);
Ix.printStackTrace();}
}
}

More so , when i use amqsput to write messages using the following command, it works, although i am connecting to QMA where L1 does not reside physically.
The output from the amqusput is
| Quote: |
C:\Program Files\MQSeries\tools\c\samples\bin>amqsput L1 QMA
Sample AMQSPUT0 start
target queue is L1
test
Sample AMQSPUT0 end
|
Now, if i alter the accessqueue function as below
| Code: |
MQQueue myq = qmgr.accessQueue( qname,
openOptions,
"QMC",
null,
null );
|
That is, specify the name of the residing queuemanager while accessing the queue, i am successfully able to put the message to the cluster Q L1 although my application connected to QMA .
I do not understand why the code in the first case does not work.
I am wondering why put from amqsput is successful and it is not successful using the java code i specified in the first case.
Am i missing somethinng ?
Can anyone help me understand wht is the reason for this discrepancy
Thanks |

if you do the open with qname and lokal qmgrname, mq looks for a local defined queue, it does not check the cluster. use a blank queuemanagername when opening the queue and it will work.

chapter 8 of the application programming guide goes into
how MQOPEN works in detail.
Also look at MQOO_BIND_NOT_FIXED and MQ_OO_BIND_ON_OPEN
you might want to look at local alias queues to the remote Q |

Why. This is using a Cluster.
