When deploying Coherence on Windows please be aware of the following:

Performance Tuning

Out of the box Windows is not optimized for background processes and heavy network loads. This may be addressed by running the optimize.reg script included in the Coherence installation's bin directory. See the Performance Tuning guide for details on the optimizations which will be performed.

Personal Firewalls

If running a firewall on a machine you may have difficulties in forming a cluster consisting of multiple computers. This can be resolved by either:

• Disable the firewall, though this is generally not recommended.
• Grant full network access to the Java executable which will run Coherence.
• Open up individual address and ports for Coherence.
  • By default Coherence will use TCP and UDP ports starting at 8088, subsequent nodes on the same machine will use increasing port numbers. Coherence may also communicate over multicast, the default address and port will differ with based on the release. See unicast-listener and multicast-listener for details on address and port configuration.
