    Database performance in clustered environment

    Vinay Kumar Newbie

      Hello,

      In clustering documentation, nothing is described for database usage.
      Is there any recommendation for a production environment.
      - Every Cluster Node with (JBoss & Database)
      - Every Cluster with JBoss & all of them using a shared Database.

      With EJB3 mechanism, which scenario is suitable for production environment.

      Please suggest.

      Vinay

          Your second configuration ( Every Cluster with JBoss & all of them using a shared Database) is the recommended one - this is the only way that each of the app servers has access to the same data. On a very large system, you might also have to use database mechanisms to "cluster" the database (such as Oracle RAC), but from the app servers' points of view, it is still a single database.
