27.5.2. Configure Multiple Site Masters (Remote Client-Server Mode)

Procedure 27.4. Set Multiple Site Masters in Remote Client-Server Mode

1. Locate the Target Configuration

   Locate the target site's configuration in the clustered-xsite.xml example configuration file. The sample configuration looks like the following example:

   <relay site="LON">
   	<remote-site name="NYC" stack="tcp" cluster="global"/>
   	<remote-site name="SFO" stack="tcp" cluster="global"/>
   	<property name="relay_multicasts">false</property>
   </relay>

2. Configure Maximum Sites

   Use the max_site_masters property to determine the maximum number of master nodes within the site. Set this value to the number of nodes in the site to make every node a master.

   <relay site="LON">
   	<remote-site name="NYC" stack="tcp" cluster="global"/>
   	<remote-site name="SFO" stack="tcp" cluster="global"/>
   	<property name="relay_multicasts">false</property>
   	<property name="max_site_masters">16</property>
   </relay>

3. Configure Site Master

   Use the can_become_site_master property to allow the node to become the site master. This flag is set to true as a default. Setting this flag to false prevents the node from becoming a site master. This is required in situations where the node does not have a network interface connected to the external network.

   <relay site="LON">
   	<remote-site name="NYC" stack="tcp" cluster="global"/>
   	<remote-site name="SFO" stack="tcp" cluster="global"/>
   	<property name="relay_multicasts">false</property>
   	<property name="max_site_masters">16</property>
   	<property name="can_become_site_master">true</property>
   </relay>
