Hi,
I have a MDB needed to send a message to a Queue Manager other than the MDB listenning to. However, I got 2103 error. Does that means the MDB onMessage() will open a connection to the QMGR it listens to until the method finished.
My scenario is that:
QMGR1
Q1_in <--- MDB_1 listen to
|
-- got msg1, then sent msg11 to Q3
Q1_out
QMGR3
Q3
|--- got msg11, reply to Q2_in (msg11Rply)
QMGR2
Q2_in <---- MDB_2 listen to
|
-- got msg11Rply, then send msg22 to Q1_out
For the first MDB_1, it works fine. However, when the MDB_2 got that message msg11Rply and got error 2103 while sending to Q1_out.
The strange thing is, if I run a single test case which is put a message into Q3 and test MDB_2 directly. I can got correct process.
BTW, I am using the same program for sending message. It's a java client sending method.
I really need to solve this problem and continue on test.
Thanks in advanced. |

| How are your QCF's defined? Are you using a bindings or a client transport? I'm guessing that it is bindings, and I believe that you have to use client in order to connect to the 2nd qmgr from inside the MDB. |

You cannot use 2 connections in the same thread.
If you want to do this you need 2 threads with different client(!) connections.

Thanks all,
You are right, before, I set up to Bind model before.
However, right now, I change to use client model and put the sending message process in a seperate thread. I got a nullpoint exception while construction MQQueueManager.
| Code: |
java.lang.NullPointerException
at com.ibm.mq.ClientConnectionRequestInfo.equals(ClientConnectionRequestInfo.java:239)
at com.ibm.mq.ManagedConnectionStore$Tuple.equals(ManagedConnectionStore.java:148)
at java.util.Hashtable.get(Hashtable.java:318)
at com.ibm.mq.ManagedConnectionStore.chooseOne(ManagedConnectionStore.java:110)
at com.ibm.mq.MQSimpleConnectionManager.allocateConnection(MQSimpleConnectionManager.java:124)
at com.ibm.mq.MQQueueManager.obtainBaseMQQueueManager(MQQueueManager.java:682)
at com.ibm.mq.MQQueueManager.construct(MQQueueManager.java:620)
at com.ibm.mq.MQQueueManager.<init>(MQQueueManager.java:393) |
Any idea on that? |

| You need to post the code snippet where you are creating the QMGR onject. |
