No that's not supported.

But in our application, many times we need to repoint databases or change log levels. And with so many instances running its really tuff to change manually.

That's exactly why we introduced the domain management in AS7 - to avoid any manual changes to multiple systems. Take a look at the AS7 documentation https://docs.jboss.org/author/display/AS71/Documentation and read about the management APIs and the command line interface which you can use write scripts or even use the admin console to manage the domain.

With JBoss 5.1 since those configs are separate files, we used to write scripts to change the file alone and no manual work was involved. Here it seems we have to do manual work. Not that bad, but yea to some extent complicated!!

 

In AS7, we no longer recommend manually changing anything in the configuration file (standalone.xml/domain.xml). Instead we provide management operations and tools which can invoke those management operations to let you change any/all the settings and those settings will be persisted back to the configuration file. Take a look at the various chapters in the documentation I pointed you to.
