Controlling the Message Distribution Service Load Balancing

The default load balancing for Information Console are set to when you install it. To change the default settings, you modify the values of the MDS_ENABLED and MDS_REFRESH_FREQUENCY_SECONDS configuration parameters.

If you are using third-party load balancing, you will need to refer to their documentation to configure load balancing. See Understanding Actuate Information Console load balancing.

How to enable the Message Distribution Service

The Message Distribution Service (MDS) is enabled by default. This procedure assumes it has been disabled.

1	Using a UTF-8 compliant code editor, open the web.xml configuration file.

2	Navigate to the lines that define MDS_ENABLED, similar to the following code:

<param-name>MDS_ENABLED</param-name>

<param-value>false</param-value>

Change the current value, if it is false, to true.

3	Navigate to the lines that define MDS_REFRESH_FREQUENCY_SECONDS, similar to the following code:

<param-name>MDS_REFRESH_FREQUENCY_SECONDS</param-name>

<param-value>0</param-value>

Change the current refresh frequency in seconds, 0 in the above example, to the desired number of seconds so that MDS will attempt to discover new nodes added to the cluster or remove nodes dropped from the cluster.

4	Save web.xml.

5	Restart the application server or servlet engine that runs Information Console.
