Common memory place across the cluster nodes

Question

Hi All,
I am a websphere application server v6.1 user. I am running an application that uses a HashMap to store common information in the form of key value pairs. The application works fine in a single server environment but the same application fails in a cluster environment. This happens because the HashMap information will not be available for the cluster environment nodes which were running on a different JVM�s.
Could anybody suggest a good design where in I can use a common place to store the HashMap information like queue, database or any common memory area which is available across the cluster nodes? I am not really familiar with the memory facilities offered by websphere server. (The use of a central database is the worst case I prefer as the application makes several calls to the database resulting in a deadlock and 100% CPU utilization)
And also the values to the HashMap were added dynamically so the memory place should allow me to add my values dynamically during the runtime.
Please suggest is there any other way or any links to refer to achieve the above situation.
Thanks in advance
-Sandeep

For a similar scenario we maintain a version flag in the DB based on which we would reload the hashmap.I'm too interested in finding out a design without DB.
