we have three Queue managers(QA,QB,QC).
we want to send messages to LQ3 of QC through QB and reply back to LQ1 on LQA using reply-to-queue.
| Code: |
On QMA
we defined below queues
DEF QR(QMC) RQMNAME(' ') RNAME(' ') XMITQ(QMB)
DEF QR(QC) RQMNAME('QMC') RNAME(' ') XMITQ('QMC')
DEF QL(QMB) USAGE(XMITQ) TRIGTYPE(FIRST) TRIGGER
on QMB
DEF QL(QMC) USAGE(XMITQ) TRIGTYPE(FIRST) TRIGGER
on QMC
DEF QL(QC)
|
how do i setup for response back on LQ1 on QA using reply-toQueue mentioned in request message.
please provide some information to achieve this.... |

I'm not sure I understand your question. Why could the application not just add the transmission queue definitions for the way back like this ?....
on QMB
DEF QL(QMA) USAGE(XMITQ) TRIGTYPE(FIRST) TRIGGER
on QMC
DEF QL(QMB) USAGE(XMITQ) TRIGTYPE(FIRST) TRIGGER
DEF QR(QMA) RQMNAME(' ') RNAME(' ') XMITQ(QMB)
Then the application can specify whatever reply queue it likes on QMA and get the responses back.
Cheers,
Paul.

And now, anyone connected to QMC has full access to the command server on QMA. |

That's a bit like saying that anyone who is connected to QMA has full access to the command server.
Are you implying that if you connect to a queue manager that you then have no control over security? Clearly that statement would be ridiculous.
There are, no doubt, security implications whenever one machine is connected to another. I didn't get the feeling that the question was about security though, but more about routing.
Cheers,
Paul.

I agree the question is not about security.
My point is that the route you have described does exactly what you have said it does. It allows any application connected to QMC to send a message to any queue on QMA.
Perhaps it's unnecessary for me to state that this also includes the command server queue. But I thought it might be helpful to do so.
Perhaps it's pessimistic of me to expect that the channel to QMA does nothing to provide any security measures. But I don't believe it's *unrealistic* to think that. |

I think we all agree that securing your channels and your queues is a good thing. However, in the original question there were these definitions.
| Quote: |
On QMA
we defined below queues
DEF QR(QMC) RQMNAME(' ') RNAME(' ') XMITQ(QMB)
DEF QR(QC) RQMNAME('QMC') RNAME(' ') XMITQ('QMC')
DEF QL(QMB) USAGE(XMITQ) TRIGTYPE(FIRST) TRIGGER
on QMB
DEF QL(QMC) USAGE(XMITQ) TRIGTYPE(FIRST) TRIGGER
on QMC
DEF QL(QC)
|
This allows anyone on QMA to target any queue on QMB or QMC and anyone on QMB to target queues on QMC. All I did was point out that the mirror set of definitions would get the response back again.
I fail to see how the mirror set of definitions is more innately insecure than anything else. Why is the direction of QMC to QMA your only cause for concern ? As I said, securing channels and queues is another topic albeit an important one.

I agree!
I merely thought it would be helpful to mention the security aspects here. |

Like, you need to inject the msg with an authorized ID in the MQMD for the command server to do what you ask it to do. Not to mention you had to inject a command msg.
Pessimistic? You Jeff? No way...  |

Should have been defined as:
| Code: |
| DEF QR(QMC) RQMNAME('QMC ') RNAME(' ') XMITQ(QMB) |
Have fun
