You can scale in an Oracle SOA Cloud Service cluster to remove a selected node from the cluster. When you scale in, Oracle SOA Cloud Service removes the selected Oracle WebLogic Server managed server instance and the VM that it is running on.
To scale in an Oracle SOA Cloud Service cluster:
- Navigate to the Topology page.
- Click the name of the service instance with the cluster that you want to scale in.
The Oracle SOA Cloud Service Instance page appears, with the Overview tile in focus, displaying detailed information about the service instance.
- Click the Topology tile.
The Topology page is displayed.
- From the
menu for the node you want to remove, choose Remove Node.
The Remove Node dialog box is displayed.
- In the Remove Node dialog box, confirm how you want to scale in.
- 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 node is removed from the
Topology page. The
Topology tile shows the number of nodes decreased by one..
Note:
At any time during the scaling process, you can check its status by opening the Activity section and clicking
![Node icon Node icon](img/GUID-74757DDB-3874-40A9-9944-C988BA29EFB7-default.gif)
for the affected node. A status panel will appear.
Note:
After scale-in, you must restart the administration server and all managed servers. This applies to both Oracle SOA and Oracle Service Bus domain configuration types, Failure to restart servers post scale-in can impact functionality.
