Scale an Oracle Java Cloud Service Node
Scaling an Oracle Java Cloud Service node allows you 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.

Scale a Node
To respond to changes in workload requirements in an Oracle Java Cloud Service instance, you can scale up a node to a larger compute shape with more Oracle Compute Units (OCPUs) and memory, or scale down a node to a smaller compute shape.
Note:
The Bring Your Own License (BYOL) option enables you to bring your on-premises Oracle WebLogic Server licenses to Oracle Cloud. BYOL instances are billed at a lower rate than other instances. See Frequently Asked Questions: Oracle BYOL to PaaS. Before you scale up or scale out a BYOL instance, you must have enough WebLogic Server licenses for the additional OCPUs that will be allocated to the instance after it is scaled.You must scale each node individually. To optimize performance, Oracle recommends that you scale all nodes within a cluster to the same specifications.
The applications that are running on the node will be temporarily unavailable while the scaling operation is in progress.
Wait for any maintenance operations on this service instance to complete, such as backup, restoration or patching operations, before you begin.
Note:
You can use these instructions to scale a compute shape of a JCS node while it is running. If the node is in the shutdown state, use the Resize REST API. See Resize a Service Instance.Add Storage to a Node
Note:
Do not use Oracle Cloud Infrastructure Compute to attach custom storage volumes to a service instance's nodes. Any custom storage volumes that you attach will be detached if the service instance is restarted.You must update the storage configuration of each node individually. You cannot remove unused storage from a node.
You cannot perform any other management operations on the service instance while the storage operation is in progress. The applications that are running on the node will be temporarily unavailable.
You cannot add storage to a node while the service instance is under maintenance, such as during a patching or backup operation.
