Hi
One particular local queue is supposed to be connected with an application .
And that application is supposed to be MQ receiver channel but it is not getting connected. How can we ensure that this queue is always connected to that channel? Previous qs results are listed below.
dis qs(TRAFFIC_VIOLATIONS_RPLY_TEMP) type(handle) all
1 : dis qs(TRAFFIC_VIOLATIONS_RPLY_TEMP) type(handle) all
AMQ8450: Display queue status details.
QUEUE(TRAFFIC_VIOLATIONS_RPLY_TEMP) TYPE(HANDLE)
APPLDESC(WebSphere MQ Channel) APPLTAG(amqrmppa)
APPLTYPE(SYSTEM) BROWSE(NO)
CHANNEL(MIP2.EGP1XC13) CONNAME(192.168.1.22)
ASTATE(NONE) HSTATE(INACTIVE)
INPUT(NO) INQUIRE(NO)
OUTPUT(YES) PID(753830)
QMURID(0.0) SET(NO)
TID(1840582)
URID(XA_FORMATID[00000000] XA_GTRID[] XA_BQUAL[])
URTYPE(QMGR)
Now there is no connection
dis qs(TRAFFIC_VIOLATIONS_RPLY_TEMP) type(handle) all
1 : dis qs(TRAFFIC_VIOLATIONS_RPLY_TEMP) type(handle) all
AMQ8565: Queue Status not found.
I can see that particular channel is running.
Thanks,
Praveen. |

So the channel is running, so what? When do you expect a channel agent to open a queue for output?

Yup the channel is running. But the channel agent is not getting connected to the queue..
Whenever messages passes it should connect? but still messages pass both ways but the agent is not getting connected to it. |

A channel agent is an application. When do applications connect to queues?

Yeah But i am still seeing messages passed through this channel but its not getting connected. Applications are connected to queues always. |

OK, you obviously need spoon-feeding - applications connect to queues when they need to, so when do you think your channel will open the queue?

| Channel will open the queue when there's a message in the queue. |

The mca may not keep a persistent handle on any queues that it is DELIVERING to.
I.e. it may be doing MQPUT1s. This means the queue is open only long enough for the message to be delivered. |

More accurately, "...Channel will open the queue when there's a message for the queue..."

If there is such a way, and it is intended for general use and does not cause an unacceptable performance loss or impact on the queue manager, then it will be publicly documented.
My point here is that you're going about this the wrong way. You should NOT be looking at "how do I change the channel to behave in a way that makes my monitoring easy", you should be looking at "what are the proper and correct things that I should be monitoring for, and what are the proper and correct things that I should be documenting instead". |
