1 Coherence TCMP clusters must be homogeneous with respect to the Coherence Edition. A TCMP cluster of one type (e.g. Standard 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 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).

5 Grid Edition is required for WAN and other deployments that implement cluster-to-cluster interconnects, including any deployment where responsibility for data and/or processing spans more than one data center and activities are coordinated between those data centers using any form of Coherence-provided messaging or connectivity, such as deployments that feature two or more TCMP clusters interconnected by Coherence*Extend.

6 InvocationService requests from clients connected via Coherence*Extend are processed by the instance of Grid Edition or Enterprise Edition to which the client is connected.

7 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.).

8 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).

9 Data Client may be used with all Coherence Server Editions.

10 Real Time Client may only be used with Grid Edition.

11 Extend-TCP is an abbreviation for Coherence*Extend configured for transport over TCP/IP.
