How-To: Migrating Logical Domains

Using Ops Center, you can create Server Pools to allow for failover and migration of virtual systems such as Logical Domains. In some cases, you'll want to migrate systems manually, either to balance the load or to perform hardware maintenance.

There's a how-to in our library that walks you through the whole procedure, and explains what prerequisites and roles are required. It also gives you a pointer to some additional resources - the Feature Reference Guide has chapters about Oracle VM Servers for SPARC and Server Pools.

Database Failover Questions

In the post about installing Ops Center, one of the steps is setting up the database that Ops Center will use. You can use a co-located database on the EC system, or you can set up your own database and configure Ops Center to use it.

On that second option, I saw a couple of questions:

Can Ops Center be installed using a Data Guard customer managed database?

Data Guard is an Oracle tool for providing high availability and disaster recovery for an Oracle database. It can be used with Ops Center. The only thing to keep in mind is that, if your database fails over to a system with different connection parameters, you need to direct Ops Center to use the new system using the Changing the Customer-Managed Database Location procedure.

Can the RemoteDBProps.txt contain entries for both the active and standby databases?

No. The RemoteDBProps.txt file is used for the initial configuration. If you have a standby database in a separate location, you have to switch using the procedure described above.

Notifications

Notifications are one of the tools you can use to keep track of your systems. They are automatic messages that are sent to specific users when their conditions are met - such as when a critical incident occurs.

Each user has their own notification profile, which specifies what level of notifications are sent - whether it's everything that happens to an asset, all incidents, or just critical incidents. It also specifies where these notifications are sent - the user interface, a specified email address, or a specified pager. You can set different levels for each destination, so that critical incidents go to the pager but less crucial issues go to the email address. If you have the user admin role you can configure a notification profile using this procedure.

The Command Line Interface for Ops Center lets you view and delete notifications as well, although configuring a notification profile can only be done through the UI.

Installing and Configuring Ops Center

Our previous post was about planning an Ops Center installation. Once you've done the planning, you're ready to install and configure the software.

The initial installation is done from the command line. You put the correct bundle on the EC and PC systems, unpack it, and install it. Depending on your planning choices you'll use a few different options with the install commands.

Once the install tells you that it's done, your final step is to log in to the UI and configure the Enterprise Controller. During the config process you will choose a connection mode (disconnected mode for dark sites or connected mode if the EC has internet access), set up the libraries for Linux, Oracle Solaris 8-10, and Oracle Solaris 11 content, and set up DHCP for OS provisioning if you need it.

Installing Ops Center is a complex process, and this post is just an overview and not a quick-start. The Oracle Solaris Installation Guide and the Linux Installation Guide go into much greater detail. If you have specific questions about installing Ops Center, let me know.
