Regarding Coherence Replication... Please help

Question

Hi,
Please go through the following scenario which need to implement and suggest me accordingly.
Scenario:
There is a service ABC (say). Our java application will receive an XML file from ABC for every 3 minutes. When we receive the first XML file, We have to store that XML data in Coherence cache and should replicate it to other instances. When we receive the next xml file (for the 3rd minute) , we should overwrite the data in the cache with this new data. Like this we should keep on overwriting the data for every 3 minutes. When some invokes our application, then we should retrieve the XML data from cache and should provide it.
Can anyone please explain me how to implement it using coherence.
Thanks a ton,
Sri

Hi Sri,

NamedCache cache = CacheFactory.getCache(<CACHE_NAME>);
cache.put(key, XML);
and should replicate it to other instances.If you truly want the XML replicated to each cluster node configure the <CACHE_NAME> to map to a replicated-scheme in your cache configuration file. If you want the XML objects to be partitioned across the cluster, thus allowing for linear increase of cache capacity as you add JVMs to the cluster, you should configure the <CACHE_NAME> to map to a distributed-scheme in your cache configuration file. I would highly recommend that latter.
When we receive the next xml file (for the 3rd minute) , we should overwrite the data in the cache with this new data. Like this we should keep on overwriting the data for every 3 minutes.
cache.put(key, XML);
When some invokes our application, then we should retrieve the XML data from cache and should provide it.Then all your application needs to do is:
NamedCache cache = CacheFactory.getCache(<CACHE_NAME>);
XML = cache.get(key);Rob
