Scaling an Oracle SOA Cloud Service Node

You can scale an Oracle SOA Cloud Service node to change its compute shape in response to changes in workload or to add storage to a node that is running out of storage. However, you cannot remove block storage from a node.

To scale an Oracle SOA Cloud Service node:

Navigate to the Topology page.
1. 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.
2. Click the Topology tile.
  The Topology page is displayed.
From the menu for the node, choose Scale Up/Down.
The Scale Up/Down Server dialog box opens.

In the Scale Up/Down Server dialog box, specify the new compute shape of the node, how much storage to add to the node, and where to add the storage, and then click Yes, Scale Up/Down Server.

Option	Description
New Compute Shape	From the drop-down list, select the new compute shape for the node. To scale up the node, choose a larger compute shape than the current compute shape. To scale down the node, choose a smaller compute shape than the current compute shape.
Additional Storage (GB)	Enter a whole number in the range 1-1,000 to specify the number of Gbytes of block storage you want to add, if any.
Add Storage to	If you are adding block storage, from the drop-down list, select one of the following storage volumes to which the storage will be added: Create New Storage Volume Extend Backup Storage Volume Extend Domain Home Storage Volume Extend Middleware Home Storage Volume

Description

New Compute Shape

From the drop-down list, select the new compute shape for the node.

To scale up the node, choose a larger compute shape than the current compute shape.
To scale down the node, choose a smaller compute shape than the current compute shape.

Additional Storage (GB)

Enter a whole number in the range 1-1,000 to specify the number of Gbytes of block storage you want to add, if any.

Add Storage to

If you are adding block storage, from the drop-down list, select one of the following storage volumes to which the storage will be added:

Create New Storage Volume
Extend Backup Storage Volume
Extend Domain Home Storage Volume
Extend Middleware Home Storage Volume

While Oracle SOA Cloud service is applying your changes, it puts the service instance into Maintenance mode, changes the state of the node to Configuring, and stops any servers running on the node. After applying your changes, Oracle SOA Cloud service starts any servers that should run on the node.

Note:

If you scale out a cluster in a service instance after scaling any of its nodes, the new node has the compute shape and the amount of storage with which the service instance was originally created. To ensure that all nodes in your cluster are equivalent, you must scale the new node to match the other nodes in your cluster.
