| I have two queue manager which is Q1 and Q3. Now in between this two queue manager I intend to have another queue manager called Q2. Q1 will be the sender, Q2 will be my point of presence (POP) and Q3 will be the receiver. So Q2 will function like a gateway between Q1 and Q3. Now messages have to travel through Q2. In Q2 do I define a local queue and the transmission queue whereby the local queue will receive messages from Q1 and add the messages into the transmission queue, which will then be retrieved and send to the local queue defined in Q3. Is this logic correct?. |

Please read the Intercommunication Manual, which provides a more detailed explanation than can be given on this board. The manual describes multi-hop, which is presumably what you are attempting.

Read about Qmanager alias.
On QM2 u need to define a REMOTEQ with RQM as QM3 and RQ as blank & transmission q as QM3 |

Q1
QREMOTE with RQNAME of the QLOCAL in Q3, and an RQMNAME of Q3.
XMITQ and SDR to Q2
Q2
RCVR from Q1
XMITQ and SDR to Q3, and the name of the XMITQ must be exactly the same as the Q3 queue manager name
Q3
RCVR from Q2
QLOCAL of the same name as the RQNAME specified in the QREMOTE in Q1
The above is the simplest form of multi-hop.

| Does this mean in Q2 I only define a Transmission Queue?. Why must the name of the XMITQ be exactly the same as the Q3 queue manager name? |

Because the receiving queue manager (Q2 in this case) extracts the RQMNAME from the message header, and looks for a 'reference' to that queue manager; that 'reference' matches to the XMITQ (Q3 in this case) and the message is placed on the XMITQ.

Its not must but rather advised way to do things....
u can have transmission queue a different name then the remote queue manager..... but in that case u need to specify transmission queue name in each and every remote queue definition...

In this case it is must as no QR is specified in Q2...sorry to be pedantic

You can still avoid creating a number of remote queues if you create a qmgr alias (see intercommunications manual)
