Consider the following rules and guidelines when you create a local cluster:
When you install the Secure Agent on Oracle Cloud Infrastructure, you can create local clusters but you can't create any other types of advanced clusters.
Before you run mappings in advanced mode on a local cluster, make sure that the Secure Agent has enough resources so that it can create a cluster and run jobs successfully, especially if the Secure Agent is already running other jobs. If the Secure Agent doesn’t have enough resources, the jobs that are already running on the Secure Agent and the mappings in advanced mode will fail. It’s recommended to have at least 8 cores and 32 GB of memory on the Secure Agent machine.
Local clusters can't run mappings that connect to Hive.
