How to Test coherence cache configuration

Question

Hi,
I have configured coherence using the below two config xmls, I had started out by trying to configure a distributed cache scheme but I am not sure if it has come up correctly. This configuration works fine from caching point of view, it even does the clustering, but my only doubt here is that how can I test whether it is actually a distributed cache or a replicated cache?
coherence-cache-config.xml
<cache-config>
     <caching-scheme-mapping>
          <cache-mapping>
               <cache-name>dist-ABCCache</cache-name>
               <scheme-name>ABC-distributed-cache-scheme</scheme-name>
          </cache-mapping>
     </caching-scheme-mapping>
     <caching-schemes>
          <!--
Distributed caching scheme.
-->
          <distributed-scheme>
               <scheme-name>ABC-distributed-cache-scheme</scheme-name>
               <lease-granularity>member</lease-granularity>
               <backing-map-scheme>
                    <local-scheme/>
               </backing-map-scheme>
               <autostart>true</autostart>
          </distributed-scheme>
          <proxy-scheme>
               <service-name>ExtendTcpProxyService</service-name>
               <thread-count>5</thread-count>
               <acceptor-config>
                    <tcp-acceptor>
                         <local-address>
                              <address>server1</address>
                              <port>####</port>

                    </tcp-acceptor>
               </acceptor-config>

Thanks for your answer but I also wanted to know if there is anyway I can verify that by the data in the cluster? You can start up the [command line application|http://coherence.oracle.com/pages/viewpage.action?pageId=16684] or write a quick class to display the information for that particular cache.
I mean can check what all data is present in each cluster member?I would suggest taking a look via JMX. In this case, you would want to look at the ServiceMBean, CacheMBean and StorageManagerMBean MBeans (take a look at the Registry for more information).
Another reason why I am not so confident if this scheme is distributed or not is that, in my config xml I do not have any backing map scheme configured so how is coherence going to do the backups in this case?
<backing-map-scheme>
     <local-scheme/>
</backing-map-scheme>You do have a "backing map" configured, it will just use the defaults.
Coherence always manages the backups automatically, transparently and dynamically for you. When using the partitioned cache (i.e. "distributed-scheme") Coherence will place the backup in a storage enabled node on a separate physical machine as the primary.
