Configure failover/round-robin with the Java Web ADF

Edit the application's facesconfig.xml file to allow connection to multiple SOMs in a failover or round-robin fashion. This is done by adding more hosts to the managed-property 'hosts' and adding a new managed-property called 'clusterType'. For example, add the following to the facesconfig.xml file:

<!—- Edit the hosts managed-property values -->
<managed-property>
<property-name>hosts</property-name>
<list-entries>
<!—- Add values for your SOM servers -->
<value>arcgis1.esri.com</value>
<value>arcgis2.esri.com</value>
</list-entries>
</managed-property>
<!—- Add a new clusterType managed-property -->
<managed-property>
<property-name>clusterType</property-name>
<value>roundrobin</value>
</managed-property>

a) Using ArcGIS Server Manager, go to the ‘Services’ tab and select ‘Configure Services Handler’.

b) Select the ‘Export’ tab.

c) Under ‘Export Web Services’, select the type of service to export (REST or Web).

d) Fill in the appropriate GIS Server credentials to connect to.

e) Select the ‘Yes’ radio button under ‘Do you have additional GIS Servers in your site that you would like to use for a failover or round-robin configuration?’ and add the appropriate GIS Servers.



f) Once complete, export the application and deploy it to a supported application server.

Note:
The username and password used must be able to connect to all the GIS Servers in the cluster for both application types.
