I want to pick messages from a local QM and copy them to a remote QM and so far I have had no luck.
My syntax seems to be off and I have had a tough time understanding how to use the various options in the README file. I don't know how to mix the two types of connections.
| Code: |
./q -m QM1 -i Q1 -m QM2 -o Q2\
...
Connecting ...connected to 'QM1'.
Connecting ...failed.
MQCONN on object 'QM2' returned 2058 QMgr name error..

Try this...
./q -m QM1 -i Q1 -o QM2/Q2 |

also, you might need
export MQSERVER=<whatever for QM2> |

Or, if the queue managers are interconnected, define a QREMOTE in QM1 and use that...

Tried it; no luck.
| Code: |
:
MQSERVER=QM2.CLNTCONN/TCP/xx.xx.xx(12345)
:
$./q -m QM1 -i Q1 -o QM2/Q2
Connecting ...connected to 'QM1'.
MQOPEN on object 'Q2' returned 2087 Unknown remote QMgr..

You can't do that in a single command unless you have a xmit queue called QM2 defined on QM1.
You can then do it that way, or use a remote queue definition. That remote queue definition will then refer to the queue on QM2
Either way the messages will travel over a standard sender channel from QM1 to QM2 (this needs to be defined as well).
OR you can save messages to a file with MA01 and run the command again to upload the file to a different QM (although qload is better for that).
To use MQ client mode in MA01 you need to code an option to do so. You can't use bindings and client mode at the same time. You could use client mode for both QM1 and QM2 with a CCDT.
However the easy answer is to understand how to send messages from one QM to another using a xmit queue and sender/receiver channel.

Yes you can. Q will let you connect to two Queue Managers either locally or over a client. So, you can indeed move message between Queue Managers without requiring other channels or transmission queues or anything. However, it is worth pointing out that it does it single phase, it won't use a global transaction etc.
Essentially you need to provide multiple -m parameters to identify the Queue Managers and you need to use parameter -xb. -xb signifies shared handles since, by default, MQ does not allow you to connect to two different Queue Managers on the same thread.
So, to copy messages from one QM to the other you could say something like...
q -m QM1 -iQ1 -m QM2 -oQ3 -xb
This will copy all the messages from QM1 queue Q1 to QM2 Q3
If you want to connect over a client for, say QM2, you would say
q -m QM1 -iQ1 -m QM2 -lmqic32 -oQ3 -xb
The parameters are relative to the last -m flag.
Hope this helps,
Paul.

Would need a CCDT for the second option.
But useful to know yet another way to use MA01!

Well, you don't *need* a CCDT - normal client rules apply. So, if you are use MQSERVER or ActiveDirectory or a PreConnect exit etc then you wouldn't need one but clearly the CCDT offers the easiest flexibility.

How can you client connect to two different QMs at the same time without a CCDT?
MQSERVER can only refer to one QM surely?

The second option was showing how you can connect to a local QM (QM1) and a client QM (QM2).
If you wanted both to be connected as clients then you would need something like......
q -m QM1 -lmqic32 -iQ1 -m QM2 -lmqic32 -oQ3 -xb
Note that we have now said -lmqic32 for both Queue Managers.
In this case, as you say, you couldn't use MQSERVER but the other mechanisms would work.

Thanks all, I went the XMITQ route and that worked!
I am going to try it the way Paul mentioned. This is what I initially set out to do.
I am trying to use ma01 as a splitter. I may end up with one cron job to move messages from one IN Q over to two OUT Qs and then using the second cron job to to clear the IN Q.
Is there an *elegant* solution to achieve the same ? |

You could use the 'native' pub/sub capability of WMQ to 'split' the messages, then it's just a case of clearing the IN queue...

There is a free open source message splitter (multiplexer) utility here

The MMX tool works out great!
I am using channel triggering with it and everything seems to be in a happy state.
Thanks all! |
