In order to have fail-over work with Oracle RAC, i guess i have to use FCF (fast connection failover mechanism).

This essentially involves including ons.jar, and setting properties on your datasource.

I believe Tomcat datasource there are specific params you can set, like as follows:

<Resource ....

...

ONSConfiguration="nodes=rac1:6200,rac2:6200"

fastConnectionFailoverEnabled="true"

implicitCachingEnabled="true"

..

/>

I am not able to find any example or documentation on how to do the equivalent thing for JBoss Datasource.

Any advice?
