Scale Up or Down
Scale an Oracle SOA Cloud Service node up or down to change its compute shape in response to changes in workload or to add storage to a node that is running out of storage. The compute shape specifies the number of Oracle Compute Units (OCPUs) and amount of memory (RAM) that you want to allocate to the node.
Note:
A scale up or down operation requires some down time as servers on the Oracle SOA Cloud Service node are automatically restarted after the scale operation. In a multinode instance cluster, the node that is scaled is restarted, while the other nodes continue running. Before scaling, make sure that there are no active running processes on the servers of the node you are scaling up or down.|
