Overview of OS Management Hub

Oracle OS Management Hub is the next-generation management solution for Oracle Linux. Use OS Management Hub to manage and monitor updates and patches for Oracle Linux environments in private data centers using a centralized management console.

OS Management Hub initially targets Oracle Linux instances in private data centers and is included with all Oracle Linux Basic and Premier Support subscriptions at no additional cost.

Note

You must have a valid Oracle Linux subscription to use the OS Management Hub service.

OS Management Hub provides:

  • Tools for tracking and resolving critical issues across an environment of Oracle Linux instances.
  • Methods for grouping systems and monitoring updates.
  • Capabilities to deliver staged rollouts of security errata and other content, with control points from development through production.
  • Integration with mission critical Oracle Linux features, such as Oracle Ksplice for zero-downtime security updates.

Resource Identifiers

Most types of Oracle Cloud Infrastructure resources have a unique, Oracle-assigned identifier called an Oracle Cloud ID (OCID). For information about the OCID format and other ways to identify your resources, see Resource Identifiers.

Retention Policy

OS Management Hub monitors your tenancy and removes job history older than 90 days.

Authorization and Authentication

Each service in Oracle Cloud Infrastructure integrates with IAM for authentication and authorization, for all interfaces (the Console, SDK or CLI, and REST API).

An administrator in your organization needs to set up compartments, user groups, dynamic groups, and policies in Identity and Access Management (IAM) that control which users can access which services, which resources, and the type of access. For example, the policies control who can create new users, create and manage the cloud network, create instances, create buckets, download objects, and so on. For more information, see Getting Started with Policies.

If you’re a regular user (not an administrator) who needs to use the Oracle Cloud Infrastructure resources that your company owns, contact your administrator to set up a user ID for you. The administrator can confirm which compartment or compartments you are permitted to use.

Tagging Resources

You can apply tags to your resources to help you organize them according to your business needs. You can apply tags at the time you create a resource, or you can update the resource later with the wanted tags. For general information about applying tags, see Resource Tags.

If you have permissions to create a resource, then you also have permissions to apply free-form tags to that resource. To apply a defined tag, you must have permissions to use the tag namespace. For more information about tagging, see Resource Tags. If you're not sure whether to apply tags, ask an administrator or skip this option. You can apply tags later.

OS Management Hub has default service limits on the maximum number of resources allowed per region.

Ways to Access Oracle Cloud Infrastructure

Learn the different ways you can access Oracle Cloud Infrastructure.

You can access Oracle Cloud Infrastructure using the Console (a browser-based interface) or the REST API. Instructions for the Console and API are included in topics throughout this guide. For a list of available SDKs, see Software Development Kits and Command Line Interface.

To access the Console, you must use a supported browser. To go to the Console sign-in page, open the navigation menu at the top of this page and click Infrastructure Console. You are prompted to enter your cloud tenant, your username, and your password.

For general information about using the API, see REST APIs.
