Updating an OS
Sun xVM Ops Center enables you to update your managed Solaris and Linux operating systems.
To ensure that your operating systems are up to date, you need to determine which patches, updates, software, and actions to apply to your system. The System Catalogs and OS Update Reports can help you determine the software and patches installed on your systems.
You can update an OS with one of the following methods:
- Use a Profile to standardize updates across your data center
- Use a System Catalog to create a quick ad hoc job for a single patch or package
- Use a report to update your OS to match a Solaris baseline
See About Updating an OS for an overview of the update features available in Sun xVM Ops Center, including the parameters and options that enable you to customize and standardize your update jobs, how Sun xVM Ops Center updates Solaris Containers, and the additional procedures to perform when your data center is configured in disconnected mode.
Before using the update procedures described in this section, you must use Sun xVM Ops Center to discover the gear that you want to work with. Discovery is the method by which Sun xVM Ops Center becomes aware of the gear, including operating systems, that it can subsequently manage. You only need to discover a particular piece of gear once. Discovered gear appears in the All Gear tree in the Navigation panel and is available for all applicable Sun xVM Ops Center operations. See Discover Gear for information about how to discover a system and add it to the Managed Gear list.

| OS Update Profiles and Policies | Describes how to establish and use policies, profiles, baselines, white lists, black lists, and catalogs to automate and customize your OS updates. |
| Solaris Baselines | A Solaris baseline is a dated collection of patches, patch metadata, and tools. Sun releases Solaris baselines on a monthly basis. When you install the patches of a baseline on a host, that system is considered to be compliant with that baseline. |
| Methods of Updating an OS | Describes the various methods of updating your operating systems. |
| Updating Solaris Containers | Describes the concepts involved in updating global and non-global zones, and the packages and parameters that determine the patch installation. |
| Uploading Patches in Disconnected Mode | Describes how to upload software while your environment is disconnected from the Enterprise Controller. |
