Cluster instance recover data cache (singleton) from another instance

Question

Greetings,
          I've created a cache object in a Singleton in my EJB for storing data
          about result requests made for database simple query. I used this
          technique because was not acceptable using entity beans due the
          extremely large information and since that database is accessed by
          multiple interfaces.
          Question:
          - every time I reloaded a server instance, the cache is cleaned. Since
          the performance result depends on this cache element, I would like to
          answer about ways of getting the cache information from other running
          instances.
          Thanks,
          Pedro Salazar.
          

Answer 1

getting the cache from other running instances would probably incur the same
          cost as that is when you retrieve from a database. May be you can do this by
          using a startup class which populates the cache.
