Subject Re: cluster example using a datasource?
Date Mon, 14 Feb 2011 06:10:17 GMT
the example below is for a postgres database using JNDI to get the
connection in all instances ... includes the cluster config.

Note the "schemaObjectPrefix" values I'm using are bit long and in
most cases unnecessary for most definitions but the workspace - where
you must have "${wsp.name}" somewhere in the "schemaObjectPrefix"
parameter or the schemas will conflict (between "default" and
"security" for example).
