I am so sorry for I have so many questions. I have read another topic about this, but I need more help.
I have some general idea.
1.Define a transfer queue with trigger.
2.Open trigger, Set type to every,depth to 1.
That is all I know.
Should I define a service for trigger?
Help me please. |

On the definition of your XMITQ ensure that you have:
TRIGGER +
TRIGTYPE(FIRST) +
INITQ('SYSTEM.CHANNEL.INITQ') +
TRIGDATA('<CHANNEL NAME>')
Take the time to read the manuals regarding triggering channels.

Thank you very much first of all!
If I dont want to use SYSTEM.CHANNEL.INITQ, how can I define a customer INITQ? |

Any (local) queue will do as long as you run a channel initiator against it.
 the intercommunications manual will give you all the clues

Why would you not want to use the 'default' initiation queue? Why add in complexity?

I have a MQ server which needs to send message to handred client, so I have the same number remote queue and XMITQ. Should I use SYSTEM.CHANNEL.INITQ support so many XMITQ?

I defined a local queue named CLInitQ, then change the defination of XMITQ, typing INITQ with 'CLInitQ' instead of SYSTEM.CHANNEL.INITQ. When I send a message with a remote queue through XMITQ, channel
was not auto started at all.
Do I miss something? |

You missed a lot of things.
- an initq queue can start multiple channels
- to start any channels you need to run a channel initiator. The qmgr does that at startup for the SYSTEM.CHANNEL.INITQ
- you have successfully created an alternate channel initq but you did not specify that you ever started a channel initiator against it. So why should it work?
- the default number of channel initiators a qmgr will accept is limited at 3
- the main reason to deviate from the default is to run the channel initiator under a non mqm id.
- The second reason to run an additional channel initiator is to load balance the start of channels across multiple initiators on a very busy qmgr with a very short chl idle before shutdown time. I would expect to see this kind of need only in a very unstable network environment

Have fun
