Coherence provides replicated and distributed data management and caching services that you can use to reliably make an application's objects and data available to all servers in a Coherence cluster. To do this, WebLogic Server retains configuration information used to locate and communicate with a Coherence cluster.
This page displays the Coherence cluster configurations that have been created in this domain.
You can show fewer or additional data points on this page by expanding Customize this table and modifying the Column Display list. Each data point displays in its own table column.
The following table lists all of the data points that you can display in columns on this page.
Name Description Name
Name of this Coherence cluster configuration.
Custom Configuration File
The name of a custom Coherence operational configuration override file.
Specifies a clustering mode of either Unicast or Multicast. If multicast is undesirable or unavailable in an environment, or when an environment is not properly configured to support multicast, then setting up the Well Known Addresses (WKA) feature is required. All cluster multicast communication is disabled if WKA is enabled.
Specify the underlying transport protocol to use for cluster communication.
Security Framework Enabled
Check if security framework is enabled
Unicast Listen Port
The port for the cluster unicast listener. A value of 0 indicates that the unicast listener port value will be derived from the server listen port. This value or the derived value will be used only if the CoherenceMemberConfigMBean unicast listen port is 0.
Unicast Port Auto Adjust
Specifies whether the unicast port will be automatically incremented if the port cannot be bound because it is already in use.
Multicast Listen Address
The IP address for the cluster multicast listener.
Multicast Listen Port
The port for the cluster multicast listener.
Time To Live
Sets the time-to-live (TTL) setting for the multicast message. The TTL setting designates how far multicast UDP/IP packets can travel on a network. The TTL is expressed in terms of how many hops a packet survives; each network interface, router, and managed switch is considered one hop. The TTL value should be set to the lowest integer value that works. Setting the value too high can use unnecessary bandwidth on other LAN segments and can even cause the operating system or network devices to disable multicast traffic.
Typically, setting the TTL value to 1 works on a simple switched backbone. A value of 2 or more may be required on an advanced backbone with intelligent switching. A value of 0 is used for single server clusters that are used for development and testing.
Specifies whether custom Coherence logging is enabled.
