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 |
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 runtime. Note: When you re-run this configuration utility for another node in the cluster, ensure that you modify this address for the new node. |
After entering the information described above, click Next to save your values and to continue.
Note: ActiveVOS 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'
