Scaling Out an Oracle SOA Cloud Service Cluster

You can scale out an Oracle SOA Cloud Service cluster to add one node to the cluster. When you scale out, Oracle SOA Cloud Service creates a new VM running an Oracle WebLogic Server managed server instance.

1. Navigate to the Topology page:
   1. Click the name of the service instance with the cluster that you want to scale out.
      The Oracle SOA Cloud Service Instance page is displayed with the Overview tile in focus, displaying detailed information about the service instance.
   2. Click the Topology tile.
      The Topology page is displayed.
2. Click Add Node.
   The Add Node dialog box is displayed.
3. To confirm you want to scale out the cluster, click Add Node.
4. After a few moments, click the (Refresh) icon to update the page.
   You might need to click the icon more than once to see any change to the page.

After a few moments of processing, the new node appears on the Topology page. The Topology tile shows the number of nodes increased by one. For a description of the items in the node line item, see Exploring the Oracle SOA Cloud Service Instance Overview Page

At any time during the scaling process, you can check its status by opening the Activity section and clicking for the affected node. A status panel will appear.

Note:

After scale-out, you must restart the administration server and all managed servers. This applies to both SOA and OSB domain configuration types, Failure to restart servers post scale-out can impact functionality.
