Hi listers,
we have the need to run 12cR2 database services as singleton services on a RAC
(that's a hard fact, please take that as given).
According to the documentation, a singleton service will not return to its
original location, when a node stops/restarts. That means in a 2-node-RAC, that
booting a node will concentrate all load on one server, and I have to
redistribute them manually again after we have the second node online again.
In admin managed databases/services I could set a preferred node, and the
service would always return to this node, as soon as it is available again. In
12.2 with a policy managed database, I can't have an admin managed service for
this DB. I can even understand why, but what I am missing now is an option to
rubber-wire a DB service to a node / instance.
The logic of server pools also prevents me from having a node joining a pool
only if the second node is away, at least as far as I came with my tests.
I appreciate any idea, as long as I don't have to start the same service name
on more than one node at the same time.
Thank you very much in advance!
