OS Management Hub Glossary

Review essential terms to help understand key concepts of OS Management Hub.

ENTITLEMENTS
Oracle Linux credentials that give you access to restricted software content.

See Managing Entitlements.

FILTER

A way of creating a derivative or a subset of existing software content.

See Editing Filters for a Custom Software Source.

GROUP

A collection of instances that's managed together for standard tasks.

See Understanding Groups.

INSTANCE

An OS installation that has registered with the service. An instance can be a virtual machine, a baremetal server, third-party cloud instance, or OCI compute instance.

Note

The terms instance, virtual machine, and system are used interchangeably in the OS Management Hub documentation.

See Understanding Instances.

JOB

An action that the service takes against one or more instances, such as installing updates or attaching software sources to an instance or group. A job can be run immediately or scheduled for a future date and time. Some jobs, such as update jobs, can also be scheduled as a recurring event. When a job runs, it dispatches work to the instance.

See Understanding Jobs.

LIFECYCLE ENVIRONMENT

A user-defined pipeline to deliver versioned content in stages.

LIFECYCLE STAGE

An individual segment of a lifecycle environment. You assign a versioned custom software source and instances to a lifecycle stage.

PROMOTION
A job that moves content into and through the stages of a lifecycle environment.

See Understanding Lifecycle Environments.

MANAGEMENT AGENT

For on-premises or third-party cloud instances, OS Management Hub provides an agent plugin to the Management Agent, which is a component of the Management Agent Cloud Service (MACS). The Management Agent provides an inventory of content from the instance to the OS Management Hub service. The OS Management Hub agent plugin interacts with the Oracle Linux content on a managed instance as directed by the service and reports data and results back to the service.

See Management Agent.

MANAGEMENT STATION

An instance assigned the role of management station mirrors and distributes software sources to instances on premises or in supported third-party clouds. A management station also acts as network proxy for on premises or third-party cloud instances to communicate with OS Management Hub in Oracle Cloud Infrastructure.

Important

Management stations aren't used by OCI instances.

The following concepts are essential to working with management stations:

PROXY
Network intermediary role of the management station that connects on-premises or third-party cloud instances to OS Management Hub in Oracle Cloud Infrastructure.
YUM MIRROR
Standard yum mirror that represents the software source content selected by the customer and used by the management station.

See Understanding Management Stations.

MONITORED RESOURCE

A resource that's monitored by the Resource Discovery and Monitoring service.

ORACLE CLOUD AGENT

For OCI instances, OS Management Hub uses an Oracle Cloud Agent plugin. The agent interacts with the instance as directed by the service and reports data and results back to the service.

See Oracle Cloud Agent.

OS MANAGEMENT HUB AGENT PLUGIN

The service plugin for either the Oracle Cloud Agent (for OCI instances) or the Management Agent (for on-premises or third-party cloud instances).

See Understanding the Agent.

PROFILE
A profile defines the default software sources for an instance, the lifecycle environment reflected on the instance, or the group to assign to the instance.

See Understanding Profiles.

REGISTRATION

The initial onboarding of an instance into the service.

See Registering an Instance.

SOFTWARE SOURCE
A software repository. The service uses software sources to provide packages and module streams to instances, lifecycle environments, and groups.

The following types of software sources are available for managing instances, lifecycles, and groups:

VENDOR SOFTWARE SOURCE
A software repository with content provided by the OS vendor.
CUSTOM SOFTWARE SOURCE
A user-defined software repository derived from vendor software sources.
VERSIONED CUSTOM SOFTWARE SOURCE
A immutable software repository derived from vendor software sources that's assigned a version designator. Versioned software sources are used for managing content in lifecycle environments.

See Understanding Software Sources.

VENDOR

An organization that provides OS distributions.
