this doesn't replicate by default bu tif your databases are replicated
it would work

hmmm okay. can/should tomee/openejb 'dynamic datasources' be used to
replicate data across all databases via some custom JPA persist method that
I would code in routed datasource?
i'm asking this question after yesterday's review of the (tomee and
openejb) dynamic datasources documentation and
can - yes (just return a datasource proxy which does the same on all
datasources for each invocation)
should - no (databases have hard times implementing it so just use
it, it will be better regarding all aspects - excepted $$ maybe)

First of all, thanks Romain for recommending the following, and for that I
will gladly start a new thread. :)
TomEE/OpenEJB and failover of datasources[1]
which references
[OpenEJB] Dynamic Datasource[2]
but I found the following TomEE example:
[TomEE] Dynamic Datasource Routing[3]
So,
Hi
Failover is native but to customiee the algo you can code anything you want
Tomee.xml is openejb.xml
Service-jar.xml is today useless (see my post)

So, the following replaces service-jar.xml (as per your post)?
Resource id=jdbc/ds type=DataSource provider=RoutedDataSource
router = failover-router
/Resource
and if I wanted to use the 'strategy' parameter, I would add to Resource as
demonstrated below?
Resource id=jdbc/ds type=DataSource
okay, i set it up as your post demonstrated, I tested already, and I see no
issues. it's time to test this in production. :)
thanks romain! like i said in the other thread, I wish I knew about this
earlier.

That's great but I'm pretty sure, you know much more than a lot of people.

FYI, I just stopped my local tomee, and recognized that my @Application
@PreDestroy has my code that stops Apache Derby prior to main and fallback
datasources are closed.
is this okay?

i guess my question really is... since I stop derby before main fallback
datasources are closed, is it likely that this might interrupt data
integrity? is it possible that I will lose data since my app stops derby
prior to tomee/openejb failover stops datasources...at tomee shutdown/stop?

it can still be enhanced a lot

Interesting. thanks Jean-Louis. Let me share some things.
When I saw Romain's response on the other thread that informed me about
tomee/openejb failover via dynamic datasource(s), I saw his post/blog
mention load-balancing, and that is what attracted me the most to this
feature.
So, after I
interesting. I can definitely use this as a reference if (ever) necessary,
thanks.
which brings me to my next question,

// take care next strategies can break multiple calls on the facade
// it is only intended to be used for connection selection

Failover is a facase over normal resources. Only these resource can/should
be pooled
