Best practice to configure HTTPService url

Question

I try to find the best way to set up the url attribute of a
large number of httpService in an application that use different
servlet as data provider.
My idea is to read an external XML file and use the text of
nodes to find the settings for the url attribute.
For example:
External file config.xml contains a node like this
<service1>
http://achille:8080/dbfw/DBSERVICE</service1>
In my <mx:Application> on creationComplete I read the
config.xml file and put the content in a Bindable variable that I
will refer in every component of my application by the syntax
XML(parentApplication.config).service1 and use the text value of
the node to set the url attribut of an httpService.
This is very important because when I install the application
at a customer the service1 url change and I have to set up the
application data provider through the external XML file.
Is there an esier way to do obtain a behavior like that ?
Thank you at all

Hi Louis,
you need to setup a service with clusterware. On both sides: primary and standby.
On primary you start them. On standby the services are also configured but stopped.
In case of switchover or failover, data guard will notice clusterware to bring them up.
You need to use this service name in your clients tnsnames.
Another issue are TCP timeouts, to protect against them you use
outbount_connect_timeout in your sqlnet.ora
