Brownfield Support for OVMSS

The area of virtualization saw quite a few enhancements with version 12.2. There's one particular virtualization enhancement that can make a big difference for a lot of people: support for brownfield Oracle VM Servers for SPARC.

Brownfield refers to Oracle VM Servers for SPARC that were created outside of Ops Center. In older versions of Ops Center, you couldn't really do anything with them - Ops Center could only manage OVM Servers that it created. If you had OVM Servers outside of Ops Center, you'd have to recreate them if you wanted to manage them.

In 12.2, though, this problem is cleared up. You can discover and manage OVM Servers for SPARC that you created outside of Ops Center, so long as the LDom Manager is running. When you discover the control domain, all of the logical domains are automatically discovered and managed and appear under the control domain in the Asset tree.

If you want to use server pools and migrate the logical domains to a different Oracle VM Server for SPARC system, you'll need to move the metadata to a shared library and use shared Fibre Channel or iSCSI LUNs for the guest domain storage and add the server to a server pool.

See the Oracle VM Server for SPARC chapter for more information.

Help in the UI

One of the things that we expanded in Ops Center 12.2 was the UI help. There are a few ways that you can get help in the UI now.

The first is the help link in the masthead. This provides you with links to the documentation, both to the doc site in general and to specific chapters in the Feature Reference Guide and the Administration Guide:


There's also a help tab in all of the wizards. It gives you some contextual information and assistance with the specific step of the wizard that you're looking at:


Finally, there are a few wizards that we've made videos for, such as the Creating a Server Pool video. Wizards that have video help have a video icon that links to the video:


We tried to make it so that some help is available, no matter where you are in the UI. Hopefully, this walkthrough has been helpful too.

Expanded Workflows

Along with the new and expanded content for 12.2, we added quite a few new workflows. I thought I'd talk a bit about the philosophy behind these docs and show you how they work.

A workflow is a document that explains how to perform a broad task by linking together multiple how-tos. It explains the task and the prerequisites, and shows you which how-tos you'll need to follow (in what order) based on your environment and the result that you're shooting for.

As an example, we'll look at the Deploy Storage Libraries workflow. It's centered on this image:

The left side shows the prerequisites. The right side presents a set of choices (indicated in white), then directs you to the necessary how-tos (the blue boxes) based on your responses. On the Deploy and Operate how-to tabs, each Workflow has its component how-tos listed immediately beneath it, like this:

Take a look at those two tabs (Deploy and Operate) to start using these workflows.

CLI Enhancements

Ops Center's Command Line Interface saw a few improvements in 12.2. If you haven't used it, by the way, Ops Center's CLI is a handy tool if you prefer CLI interactions over the UI or if you want to create your own scripts for automation.

The biggest improvement was in the area of certificates. When you connect to your Enterprise Controller from a remote system, you must accept the server's certificates. Once accepted, these certificates are stored in a local trust store and don't need to be accepted each time. You can also use the -a | --accept-all-certificates option to automatically accept these certificates, and use the new certificates mode to view and manage the list of trusted certificates for remote ECs.

There's also a new option, -C <channel>,  that you can use in the Update Mode to specify a channel name when you're creating an OS update profile or working with OS update content.

For more information about the CLI, you should take a look at the Command Line Interface Guide.

New Documents in the 12.2 Library

In addition to the new features introduced in 12.2, we've also added some new books to the documentation to make the product easier to use. Here's a rundown of the new books:

  • Upgrade Guide: This book contains all of the information you need to upgrade your environment to version 12.2. Each chapter focuses on a specific environment and upgrade process, so you can focus on the information that's relevant to you.

  • Ports and Protocols Guide: This book lists the ports and protocols that Ops Center uses and the websites that it accesses when in Connected Mode. This is particularly handy if you're setting up a new installation.

  • Feature Reference Appendix Guide: This book includes several appendixes that we've moved out of the Feature Reference guide in order to streamline it. It includes the Asset Attributes tables, and the Expression Query Language, Library Incidents, and API appendixes.

  • Oracle Enterprise Manager Ops Center Command Line Interface Guide: This guide explains how to use the Ops Center CLI, and includes the CLI man pages.

  • How Tos and workflows: We've added quite a few How-tos and workflows in 12.2. How-tos are short documents that walk you through a specific procedure, and workflows string these how-tos together to complete larger tasks. These docs are collected in the Deploy and Operate libraries.

These new books, as well as the rest of the documentation, are all available in the documentation library.
