Hi,
Can some one give answers for this.
Thanks,
Robert
An existing cluster has two queue managers, LONDON and NEW_YORK. Only LONDON has a full repository. A queue manager,
PARIS, is being added to the cluster. It needs to send messages to the INVENTQ queue hosted by queue manager NEW_YORK and to
the PAYROLL queue hosted by queue manager LONDON. Network connectivity exists between all three locations. How many
additional definitions are required at queue managers LONDON and NEW_YORK to add queue manager PARIS to the cluster?
A. 0
B. 2
C. 4
D. It varies based on platform
There are two channels to send messages from queue manager QM1 to queue manager QM2. Channel C1 uses transmission queue
QM1.QM2 and channel C2 uses transmission queue QM2. QM1 has a remote queue definition, Q2, which specifies QM1.QM2 as the
transmission queue to reach QM2. An application connected to QM1 performs an MQPUT1 specifying both an object queue name Q2
and an object queue manager name QM2. Which of the following channel(s) will be used to transmit the message?
A. C1
B. C2
C. C1 or C2 will be selected
D. No transmission will occur |

Well I can answer the second it will be channel C2
The reason for this is when the MQPUT1 is done the queue manager specified is QM2 and MQSeries will search for a queue with this name and it will place the message in that queue.
I can take a somewhat good guess at the first one, and pick 2
you need to define a cluster sender and cluster reciever channel to the
repository queue manager and that should be it.

Answer to the first one:
A
why ??
How many

When dealing with clusters, only full repos. qmgrs have to be connected using defined channels (by hand).
When you add a qmgr to a cluster you'll define a cluster receiver channel (TO.PARIS) and a cluster sender channel (TO.LONDON) and that's all.
If the queuemanagers in the cluster finds out they needs more channels, they just define them.
I did a small writing piece (on security) a while ago:

I hope it can inspire ....

How can the PARIS Queue manager be added without creating any channels ???? It needs to know where the repository is located

When PARIS queue manager is added to the cluster. we need to establish a communication between the PARIS queue manager and one of the queue managers holding full repository(In our case we have only one full repository queue manager).
SO we need to define two channels (To.Paris) and (To.London).
the answer is B
For the first question can you give the exact scenario. This is what i understood.
At QM1
QM1.QM2 - transmission queue
Q2 - remote queue definition of a queue(say Q2 @ QM2)
At QM2
QM2.QM1 is the transmission queue
Q2 local queue
C1 : uses QM1.QM2
C2: uses QM2.QM1
if this is the scenario, when an application issues an MQPUT1 call channel C1 will be used.
If i am wrong please correct me.
Thank you,
Paruvan |

Jeff, Peruvan,
Read the question carafully. Joergen is right. At queue managers LONDON and NEW_YORK there's no need to define any channels. You define 2 channels only at PARIS

And now you'll see why it's VERY important to have a good understanding on how WMQ-clustering works and how the security works on the Cluster channels on the full-repos qmgrs.
The only place where you can keep a joining qmgr away is by protecting the cluster receiver channel of the full-repos qmgrs.
I did a test on a live system, and it took me about half an hour to get in the cluster. There was no security exits and no SSL specs there, en by guessing a little bit... my pirate qmgr started to receive messages.... Hopefully it was on a testing system.
just my $0.02

Just to get it straight, please...
And those 2 channels at PARIS would be TO.LONDON (CLUSSDR) and TO.PARIS(CLUSRCVR)??
The LONDON queue manager creates TO.PARIS (CLUSSDR) based on the TO.PARIS (CLUSRCVR) definition?
Thanks

You got it right Gina.
The channels at PARIS are manually defined, the ones at London are defined automagically by MQ clustering.
