 distributed-cache-clear-enabled="false">

 <group-map group-name="org.ofbiz" datasource-name="localpostgres"/>
 <group-map group-name="org.ofbiz" datasource-name="localpostnew"/>

 </delegator>

 <delegator name="default-no-eca" entity-model-reader="main" entity-group-reader="main" entity-eca-reader="main"

 <group-map group-name="org.ofbiz" datasource-name="localpostgres"/>
 <group-map group-name="org.ofbiz" datasource-name="localpostnew"/>

 </delegator>

 <delegator name="test" entity-model-reader="main" entity-group-reader="main" entity-eca-reader="main">
 <group-map group-name="org.ofbiz" datasource-name="localpostgres"/>
