Clustering Configuration

ActiveVOS Server can be deployed to a cluster. The following information is required to ensure communication between all the clustered nodes.

Parameter	Default Value	Description
Enable Clustering	(not enabled) false	This option enables or disables cluster mode.
Cluster Multicast Address	228.1.221.1	The multicast address that the membership will broadcast its presence and listen for other heartbeats on. You must use an address within this range: 224.0.1.0 through 239.255.255.255.
Cluster Multicast Port	45566	The multicast port. The multicast port, in conjunction with the address, is what creates a cluster group.
Cluster Binding Address	(none)	(Optional). Use this attribute if you wish to bind your multicast traffic to a specific network interface. You can leave this address blank, and it will be filled in with the default network adapter's IP address at run time. When you re-run this configuration utility for another node in the cluster, ensure that you modify this address for the new node.

ActiveVOS Server creates default engine instance names based on the host name and main connector port. If desired, when you start Tomcat, you can specify your own logical name for each node. To specify your own names, set a

JAVA_OPTS

variable before running your

startup.bat

(or

startup.sh

) file.

The

JAVA_OPTS

setting should look like the following example:

In Windows:

SET JAVA_OPTS='-Dae.engine.name=engineOne'

In Linux:

export JAVA_OPTS='-Dae.engine.name=engineOne'

After entering the information described above, click Next
to save your values and to continue.
