A local cluster is a simple, single-node cluster that you can start on the Secure Agent machine. You can use a local cluster to quickly onboard projects for advanced use cases. A local cluster can only run mappings in advanced mode.
A local cluster can run on-premises or in the following cloud environments:
Oracle Cloud Infrastructure
You can set up a local cluster on a virtual machine with minimal permissions and resource requirements.
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.
The local cluster has a single node with processing capacity that depends on the local machine. The cluster can access staging and log locations on the cloud or in local storage that is attached to the cluster node. The local cluster times out after five minutes if there are no jobs running on the cluster.
Before you run mappings in advanced mode on a local cluster, make sure that the agent has enough resources so that it can create a cluster and run jobs successfully, especially if the agent is already running other jobs. If the agent doesn’t have enough resources, the jobs that are already running on the 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 agent machine.
