Hi,
I am new to MQSeries So please bear with me.I am trying to communicate with a queue manager outside the cluster, one or more queue managers inside the cluster must act as a gateway.I am having QM1 in m/c1 and QM2,QM3 in m/c2.All Qmgrs comes under cluster and here QM1 and QM2 are Repoistary Qmgrs and QM3 is a gateway Qmgr.I am having CLUSQ1 in both QM1 and QM2 and through gateway qmgr i am able to put messages in the CLUSQ1.Here i am able to achieve load balancing.
Now i have created QM4 in m/c1 and it's not in cluster and qremote definiton for CLUSQ1 was created using cmd:
DEFINE QREMOTE(CLUSQ1) RNAME(CLUSQ1) RQMNAME(QM2) XMITQ(QM3)
and also i have created sender/receiver channel in QM4 to communicate with QM3.
When an application at QM4 issues an MQPUT call to put a message to CLUSQ1 the below exception occurs.
<<MQException thrown is : com.ibm.mq.MQException: MQJE001: Completion Code 2, Reason 2196>>
I have set only MQC.MQOO_OUTPUT in open options.
Please any one help me to solve this problem. |

For clarification, the sender/receiver in QM4 that points to QM3 is servicing the xmitq QM3 isn't it? I ask as reason code 2196 = MQRC_UNKNOWN_XMIT_Q and you don't refer to it.

As well as defining the sender/receiver channels, have you defined an xmitq called QM3?
If you still couldn't able to understand, please post the definitions of the sender and receiver channels in QM4 that communicate with QM3

On QM4 I have created the following sender/reciever channel.
DEFINE CHANNEL(QM4.SDR) CHLTYPE(SDR) XMITQ(TRANQ3) CONNAME('<ip(port)>') DESCR('Sender channel for queue manager QM4')
DEFINE CHANNEL(QM4.RCVR) CHLTYPE(RCVR) DESCR('Receiver channel for queue manager QM4')
DEFINE QLOCAL(TRANQ3) USAGE(XMITQ)
So i have to put TRANQ3 in the XMITQ of QREMOTE defintion .Am i right?
DEFINE QREMOTE(CLUSQ1) RNAME(CLUSQ1) RQMNAME(QM2) XMITQ(QM3) |

Also for this kind of clustering do not give RQMNAME.
DEFINE QREMOTE(CLUSQ1) RNAME(CLUSQ1) XMITQ(TRANQ3) |

I don't see what you mean by "I have put TRANQ3 in the XMITQ of QREMOTE definition". I think this is where your "unknown xmitq error is coming from"....

Thanz all...
Now the 2196 error has solved.
When an application at QM4 issues an MQPUT call to put a message to CLUSQ1,all the messages were got stored in TRANQ3.It's not get routed to QM1 or QM2 through Gateway Qmgr.Actually i want to achieve load balancing
What could be the problem?
Please any one help me to solve this problem |

If all the messages are sitting in the xmitq, the channel's gone funny IMHO... 
Have you changed the remote queue definition as vennela suggested?

The thing is if I create QRemote with RQMNAME(QM1) then all the messages are routed to QM1 alone.(No load balancing occurs)
DEFINE QREMOTE(CLUSQ1) RNAME(CLUSQ1) RQMNAME(QM1) XMITQ(TRANQ3)
If I create QRemote with RQNAME(QM3)(ie Gateway Qmgr) then message are not ruouted to QM1 or QM2 but channel is up and running.
DEFINE QREMOTE(CLUSQ1) RNAME(CLUSQ1) RQMNAME(QM3) XMITQ(TRANQ3)
If I create QRemote with out RQNAME() then it's throwing Exception
<<MQJE001: Completion Code 2, Reason 2087>> |

So in this situation your messages sit on the xmitq and are not transmitted, are not placed on any dead letter queues, just sit there unmoving even though the channel is up and running?

I have one suggestion
Why not name the XMITQ same as the REMOTE QMGR
On QM4 create a XMITQ called QM3
Alter the channel to use the new XMITQ |

If you are moving messages from a non clustered qmgr to a cluster gateway qmgr and want load balancing, set up a cluster alias on the gateway. This should do it.
Enjoy
