Getting Started
Oracle Utilities Live Energy Connect (LEC) v8.0 is the next-generation update to the original LEC v7.1 product that is based on a microservices architecture using cloud-native tools and patterns and delivered as an on-premise solution. LEC v8.0's services run on top of a technology called Oracle Cloud Native Environment (OCNE), which is a fully integrated suite for the development and management of cloud-native applications. The LEC v8.0 installer installs OCNE v1.7 and brings up a Kubernetes (k8s) cluster on one or more Oracle Linux hosts. The installer then deploys and configures LEC V8.0's resources and services on this Kubernetes cluster. LEC V8.0's installer supports various OCNE Kubernetes cluster topologies (for example, a single-node compact cluster, a three-node compact cluster, or a cluster with three or more control nodes and two or more worker nodes).
Note: The term "node" in this document refers to a host being used in a Kubernetes cluster as a Kubernetes node. For more information about OCNE and Kubernetes terminology, refer to OCNE's "Concepts" document here: https://docs.oracle.com/en/operating-systems/olcne/1.7/concepts/.
The Oracle Utilities Live Energy Connect v8.0 installer is distributed as a self-extracting TAR archive that will install product components (for example, configuration files, container images, Helm charts, and so on) to the target hosts. Oracle Utilities Live Energy Connect v8.0 must be installed on a host or hosts running Oracle Linux 8 (OL8) or Oracle Linux 9 (OL9). The Oracle Utilities Live Energy Connect v8.0 installation process requires access to certain DNF repos from the Oracle Yum server and certain container images from the Oracle Container Registry. It is recommended that during installation and any patching the target host systems are configured to use a customer-managed, mirrored Yum server that can serve the required software packages and a mirrored container registry that can serve the required OCNE images. These mirrored yum servers should be provisioned from the Oracle Linux Yum server at https://yum.oracle.com and the Oracle Container Registry at https://container-registry.oracle.com/v2/. Note that where direct access to these repositories is allowed, mirroring is not required.
