Hi Everyone,
I would like to know, it config and schema partitions of one server node
can be candidate for replication?
Yes.
If replication of some ApacheDS instance
will also clone its config and schema partition, we have a little problem
because of the randomly assigned OIDs to component factories. So lets say
ApacheDS1 and ApacheDS2 both have same set of interceptors, because of the
nature of OSGI those can be introduced in different order in two different
server node which results in schema partitions having different
OID assignments for same components across 2 server node.
We should not affect random OID to components. An OID should identify a
unique object, so if you have some instance of this object on many
instances of the server, then they should always have the same OID.
This is something we've postponed to discuss later, it's not a concern for
single server but in replication scenario i'd like to know how this effects
consistency between distinct server nodes. I'm not so sure what is being
replicated in our implementation, some partition or entire server with all
of its runtime components and configuration?
Depends. Replication is supposed to be configurable. You can replicate
only part of the data, it's up to the administrator to tell what should
be replicated, or not.
In the standard scenario, the configuration and schema should be
replicated, that's pretty mandatory.
Does it help ?
