Data Pre Load

Question

Hi,
I have two servers with Server 1 and Server 2(I mean two different machine) and both the servers are configured with Distributed cache. For example Server 1 have a cache name "ABC" and Server 2 have a cache name "XYZ".
I want to pre load the same data to both the servers with different cache names and my JOB java class is pointing to tangosol override file for Server 1.
How can I load the data to server 2 with server 1 tangosol override file?
I dont want to use push replication patteren.
Thanks,
Raj.

Hi Raj
You cannot get the storage enabled members from an Extend client as the cache service will be a RemoteCacheService or more likely a SafeCacheService wrapping a RemoteCacheService.
I am not sure I follow exactly what you are trying to achieve from your posts above.
Why do you want to get the storage enabled members - is is so that you can make the same call invocationService.execute(task,Collections.singleton(members.toArray()[0]), null); to cluster two from cluster one?
If you want to do this then you need two invocable, one is LoaderInvocable class you mention above and the other looks like this:
public class RemoteLoaderInvocable extends AbstractInvocable {
    private String cacheName;
    private String springBeanId;
    public RemoteLoaderInvocable() {
    public RemoteLoaderInvocable(String cacheName, String springBeanId) {
        this.cacheName = cacheName;
        this.springBeanId = springBeanId;
    @Override
    public void run() {
        NamedCache cache = CacheFactory.getCache(cacheName);
        Set<Member> memberSet = ((PartitionedService) cache.getCacheService()).getOwnershipEnabledMembers();
        Member[] members = memberSet.toArray(new Member[memberSet.size()]);
        LoaderInvocable task = new LoaderInvocable(cacheName,springBeanId);
        getService().query(task, members);
}You would need to make the above class properly implement POF of whatever you are using for serialization.
You then declare a remote invocation scheme like you have for the remote cache scheme in cluster 1
<remote-invocation-scheme>
    <scheme-name>tier-2-proxy-invocation-scheme</scheme-name>
    <service-name>ExtendTcpProxyInvocationService</service-name>
    <initiator-config>
        <tcp-initiator>
            <remote-addresses>
                <socket-address>
                    <address>localhost</address>
                    <port>6005</port>
                </socket-address>
            </remote-addresses>
            <connect-timeout>20s</connect-timeout>
        </tcp-initiator>
        <outgoing-message-handler>
            <request-timeout>20s</request-timeout>
        </outgoing-message-handler>
    </initiator-config>
</remote-invocation-scheme>Then in cluster1 you can do...
InvocationService cluster2Service = CacheFactory.getService("ExtendTcpProxyInvocationService");
service.query(new RemoteLoaderInvocable(cacheName, springBeanId), null);That will allow you to execute your LoaderInvocable from cluster 1 against storage enabled members in cluster 2, but as I said, I don't see what you are really trying to do.
