Planning an Ops Center Installation

Installing Ops Center in your environment takes some planning. There are several planning decisions that you need to make before you can kick off the installation and configuration.

The first decision is whether or not you want to set up High Availability for your Enterprise Controller. You can set up Ops Center with a single Enterprise Controller, or you can use Oracle Clusterware to set up multiple ECs in a cluster. Having multiple ECs uses more systems, but it also makes your environment much more resistant to system failures; EC failover is much quicker than restoring a single EC from a backup file.

Figuring out where you want to put the product database is your next step. You can use a co-located database, which Ops Center can install on the Enterprise Controller system. However, if you're using EC HA, or if you want to have more control over the database, you can use an existing Oracle Database 11g.

Finally, before you begin the installation, you should decide how many Proxy Controllers you want to use. Proxy Controllers work with the Enterprise Controller to execute jobs. One Proxy Controller can generally handle about a thousand managed systems. If you have fewer than that, you can enable the co-located Proxy Controller on the Enterprise Controller system, but if you have more you're liable to want multiple Proxy Controllers on separate systems. Also, if you plan on performing OS provisioning, you'll want to have Proxy Controllers on the networks of the OSP target systems.

Planning an Ops Center installation is a complex process, and this post is just an overview. The Oracle Solaris Installation Guide and the Linux Installation Guide go into much greater detail. If you have specific questions about planning an installation, let me know.

New OCDoctor released

There's a new version of the OCDoctor available - 4.26. It makes the connectivity check option a bit clearer, and checks for several new issues in troubleshooting.

You can get the new version at https://updates.oracle.com/OCDoctor/OCDoctor-latest.zip. If you have an Ops Center installation in connected mode, an automated job will get the new version for you.

Using Connected Mode

When you get started using Ops Center, you choose a connection mode. You can use Disconnected Mode, which works for sites without internet access; Connected Mode, which uses an internet connection; or you can set up the connection mode later.

Using Ops Center in Connected Mode can make your life easier in many ways. It lets you download packages and updates, get automatic firmware updates, download the latest OCDoctor utility and Ops Center updates, and file service requests. However, if you're currently using Disconnected Mode or if you didn't pick one during config, there are a couple of things you need to do in order to start using Connected Mode.

First, you need to register your Enterprise Controller.

Next, supply your MOS credentials in the Authentications. These MOS credentials are used to access the Oracle Knowledge Base.

Once you've taken these steps, you can switch to Connected Mode.

What would you like to see here?

When I'm writing for this blog, I try to focus on issues and questions that actual Ops Center users are dealing with. As a reader, though, I know that you might have issues or topics that you'd like to see me discuss.

So, I'd like to invite you to let me know if there's any topic that you'd like to discuss. You can leave a comment here, or you can tweet your ideas to our twitter account, @oracleopscenter. Either way, let me know what you'd like to see.
