Hi All,
I have a doubt, can you please clarify here.
For example
1.If we have two full repositories(FR) say QM1 and QM2. two partial repositories QM3, QM4.
2.Channels from QM3 and QM4 are defined to QM1 only.
3.QM3 is sender and QM4 is receiver. Messages sent by QM3 are reaching QM4 through full repository QM1.
In this scenario if full repository QM1 is down then will messages from QM3 to QM4 flow? if yes how messages flow from QM3 to QM4 though QM3 has only connection to QM1.
Thanks In Advance |

This is not how MQ clustering works.
The app messages flow directly from QM3 to QM4 in your example. Automatic Cluster channels are created between QMs in the cluster as needed by the cluster.

ok you mean to say messages uses CLUSDRA channel is it?
if messages can flow through CLUSDRA, then is there any time period to pass cluster information or does it works normal? |

There is plenty of information on this in the documentation.
It is of value to you personally to struggle with the documentation.
It is of value to you personally to struggle to set up a test environment and do your own experiments. |

Define "cluster information". Communication between the FR & PR (QM3 & QM1) will resume when it's back.
