------------------------------------
>Thanks for investigating this Narayanan. Just to be sure: does
>this mean that all operations are logged if we turn the
>DERBY-239 mechanism on?
I guess you mean if we do the same thing being done in
DERBY-239 would it log all operations. Seems like it at first
look. I however will dig deeper here and revert back.

> It would be nice to have replication functionality to Derby; many potential
> Derby users seem to want this. The attached functional specification lists
> some initial thoughts for how this feature may work.
> Dag Wanvik had a look at this functionality some months ago. He wrote a proof
> of concept patch that enables replication by copying (using file system copy)
> and redoing the existing Derby transaction log to the slave (unfortunately, I
> can not find the mail thread now).
> DERBY-2852 contains a patch that enables replication by sending dedicated
> logical log records to the slave through a network connection and redoing
> these.
> Replication has been requested and discussed previously in multiple threads,
> including these:
