		<summary type="html">&lt;p&gt;Created page with &amp;quot;When running a number of Load Balanced Registries, it is recommended that a single Registry is the primary server and the rest are secondary servers.    When a Registry is run...&amp;quot;&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;When running a number of Load Balanced Registries, it is recommended that a single Registry is the primary server and the rest are secondary servers.  &lt;br /&gt;
&lt;br /&gt;
When a Registry is running in &amp;quot;Secondary Server&amp;quot; mode, certain tasks are not performed. In particular when using Fusion Portal to perform CRON jobs, &amp;quot;secondary server&amp;quot; Registries do not perform the CRON jobs of obtaining structures and data. This prevents unnecessary synchronization tasks being performed. &lt;br /&gt;
&lt;br /&gt;
By way of example: if there are 3 Registries, one of which is primary, and the other two are secondary, when the primary performs a CRON job to get data from an external server, the primary Registry obtains the data, loads it into its store then the other 2 Registries (via the load-balance mechanism) notice that there is a change and so automatically obtain the data.  If none were secondary servers, all 3 Registries would request the data from the external store and then persist it to their own stores. Each Registry would then signal a change and more work is required to sync the Registries with each other.&lt;br /&gt;
&lt;br /&gt;
To set a Registry into &amp;quot;secondary server&amp;quot; mode, the JVM running it should be supplied with the system property:&lt;br /&gt;
  -Dserver.secondary=true&lt;br /&gt;
&lt;br /&gt;
