  • 1 Coherence TCMP clusters must be homogeneous with respect to the Coherence Edition. A TCMP cluster of one type (e.g. Caching Edition) may connect to a TCMP cluster of another type (e.g. Grid Edition) as a Data Client or as a Real Time Client, but this requires server-side licenses. The connection type is configurable and defaults to Real Time Client.
  • 2 Supports integration with a local MBeanServer. This, in conjunction with local JMX "agents", allows this node to provide management and monitoring features. Clustered JMX support adds the ability for this node to manage and monitor remote nodes as well.
  • 3 Coherence Editions may not be mixed within the context of a single TCMP-based cluster. Integration of different Edition types is accomplished via Coherence*Extend (with each cluster acting as either a Data Client or a Real Time Client).
  • 4 Caching Edition does not support InvocationService, which is required for an additional "sticky" load balancer optimization.
  • 5 Parallel support for InvocableMap and QueryMap will result in server-side execution whenever possible, minimizing data transfer, allowing use of indexing, and parallelizing execution across the cluster. Without parallel support, the operations will retrieve the full dataset to the client for evaluation (which may be very inefficient).
  • 6 Data Grid Edition is required for WAN deployments.
  • 7 InvocationService requests from Data Client and Real Time Client are client-only, and there are limitations in Coherence 3.2.
  • 8 Oracle's cluster-aware wire protocol (TCMP) provides detailed knowledge of the entire cluster that enables direct server access for lower latency and higher throughput, faster failover/failback/rebalancing, and the ability for any participating member to act as a service provider (e.g. data management, remote invocation, management and monitoring, etc.).
  • 9 Coherence*Extend is used to extend the core TCMP cluster to a greater ranging network, including desktops, other servers and WAN links. The Coherence*Extend protocol may be transported over TCP/IP (optimal performance) or over a pre-existing JMS provider (for compatibility with existing infrastructure).
