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.
