Sebastian,
it seems like that our configurtion concept demands a chain of two
RAIDb-0-Controllers after each other. Unfortunately our tests weren't
successful because of a wrong connectionTestStatement. We tried to use
'select now()' because this one is used, when you have a nested
RAIDb-0-1 configuration. But it doesn`t seem to work with two RAIDb-0s
in a row.
Does someone have expirience with that?
You should use the same connection test statement everywhere, which is
the one that matches the underlying database.
However, startup is tricky since you must first start the subcontroller,
enable its backends and only after start the top level controller. Your
test statements might be correct but your init phase might not be correct.
Why do you need to cascade 2 RAIDb-0 controllers?
Thanks for your feedback,
Emmanuel
