Need Help regarding initial configuration for distributed cache

Question

Hi ,
I am new to tangosol and trying to setup a basic partitioned distributed cache ,But I am not being able to do so
Here is my Scenario,
My Application DataServer create the instance of Tangosolcache .
I have this config.xml set in my machine where my application start.
<?xml version="1.0"?>
<!DOCTYPE cache-config SYSTEM "cache-config.dtd">
<cache-config>
<caching-scheme-mapping>
<!--
Caches with any name will be created as default near.
-->
<cache-mapping>
<cache-name>*</cache-name>
<scheme-name>default-distributed</scheme-name>
</cache-mapping>
</caching-scheme-mapping>
<caching-schemes>
<!--
Default Distributed caching scheme.
-->
<distributed-scheme>
<scheme-name>default-distributed</scheme-name>
<service-name>DistributedCache</service-name>
<backing-map-scheme>
<class-scheme>
<scheme-ref>default-backing-map</scheme-ref>
</class-scheme>
</backing-map-scheme>
<autostart>true</autostart>
</distributed-scheme>
<!--
Default backing map scheme definition used by all the caches that do
not require any eviction policies
-->
<class-scheme>
<scheme-name>default-backing-map</scheme-name>
<class-name>com.tangosol.util.SafeHashMap</class-name>
<init-params></init-params>
</class-scheme>
</caching-schemes>
</cache-config>
Now on the same machine I start a different client using the command
java -Dtangosol.coherence.distributed.localstorage=false -Dtangosol.coherence.cacheconfig=near-cache-config.xml -classpath
"C:/calypso/software/release/build" -jar ../lib/coherence.jar
The problem I am facing is
1)If I do not start the client even then my application server cache the data .Ideally my config.xml setting is set to
distributed so under no case it should cache the data in its local ...
2)I want to bind my differet cache on different process on different machine .
say
for e.g
machine1 should cache cache1 object
machine2 should cache cache2 object
and so on .......but i could not find any documentation which explain how to do this setting .Can some one give me example of
how to do it ....
3)I want to know the details of cache stored in any particular node how do I know say for e.g machine1 contains so and so
cache and it corresponding object values ... etc .....
Regards
Mahesh

Hi Thanks for answer.
After digging into the wiki lot i found out something related to KeyAssociation I think what I need is something like implementation of KeyAssociation and that
store the particular cache type object on particular node or group of node
Say for e,g I want to have this kind of setup
Cache1-->node1,node2 as I forecast this would take lot of memory (So i assign this jvms like 10 G)
Cache2-->node3 to assign small memory (like 2G)
and so on ...
From the wiki documentation i see
Key Association
By default the specific set of entries assigned to each partition is transparent to the application. In some cases it may be advantageous to keep certain related entries within the same cluster node. A key-associator may be used to indicate related entries, the partitioned cache service will ensure that associated entries reside on the same partition, and thus on the same cluster node. Alternatively, key association may be specified from within the application code by using keys which implement the com.tangosol.net.cache.KeyAssociation interface.
Do someone have any example of explaining how this is done in the simplest way ..
