Anyway, we have reached a point when we can say there is a timeout, so we can tell the customer a value for "latency", am I right ?

The server defines a single lease period for all state held by a NFS
client. If the client does not renew its lease within the defined
period, ... |
Again, there is no "unique" value, but it has to be configured in NFS.
Have a nice day !

Also, there's nothing particular that actually *prevents* you from running more than one MI standby qmgr.
It's just not recommended and you won't really have any control over which one gets the file lock first (who's got the button?) |
And if you run more than one stand by instance, remember to check your licensing model with your IBM Rep.
Have fun

Yes.
In the same way there's a certain amount of latency before HACMP / Veritas / SCS / ... detects there's an issue and fails over in this Active / Passive model.
If you want to avoid this, you need an Active / Active model. Which comes with both advantages and disadvantages, just like Active / Passive.
