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.The following types of scaling operations can be performed automatically by using scaling rules:
-
Add a new node to the instance (scale out) when the average memory utilization on all nodes is greater than or equal to a specified percentage.
-
Remove a node from the instance (scale in) when the maximum amount of memory in use on all nodes is less than a specified size.
Each service instance can be associated with at most one scale-in rule and one scale-out rule.
Wait for any maintenance operations on this service instance to complete, such as backup, restoration or patching operations, before you begin.
