The best practice for clustering or any multiple server (machine) environment is the manage everything with one QMC. A single QMC will manage both your QVS server cluster and your QDS (Publisher). Why do you see the necessity for three QMCs?
The architecture was choosen like this to provide high availability of all platform objects. so, for exemple, if one of the two QVS machines is down, its QMC will not be accessible and we must use the other QMC of the other qvs machine. but, currently, when we create tasks via the QMC1 these tasks don't appear in QMC2.
That's why I'm looking for a manner to configure the QV management services to have the identic QMCs and to have synchronised QMCs.
I don't know if I can share the same repository (QVPR folder) for the three QMCs as well as it contains all tasks informations and history of scheduled tasks, etc...?
if it is, is it possible to use simultanusly two QMCs that share the same QVPR folder (repository)?.
