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.

Optimizing OS performance

With the right information, there's a lot that you can do to improve the performance of an operating system. However, it can be time-consuming to gather that information in a large environment with hundreds or thousands of operating systems, Oracle Solaris Zones, or Oracle VM Servers.

Ops Center's OS Analytics tools can help you gather the information that you need to tune your operating systems. For operating systems managed by Ops Center, you can view OS performance info like CPU and memory utilization, process details, and virtualization capacity. For Oracle Solaris systems, you can also view the status and details of SMF services.

We put together a how-to that walks you through the process of viewing all of this information.

How To: Access the Ops Center Database

Ops Center uses an Oracle Database to store product data. Normally you'll use the Ops Center UI and won't access the database directly, but it can occasionally be useful to see the database contents directly.

We've put together a How-To that explains how to view the database directly. You can make this connection either using Oracle SQL Developer, or from the command line using SQL*Plus. The How-To walks you through both procedures.

How To: Discover an Oracle SPARC T5 Server

When you're deploying new hardware, it's helpful to have as specific a plan as possible. For instance, it's good to know how to run a discovery in Ops Center, but if you have a guide that specifically explains how to discover the type of hardware that you're installing, that makes your job even simpler.

With that in mind, we put together a How-To that explains how to discover new Oracle SPARC T5 servers. It walks you through creating IPMI and SSH credentials, creating a discovery profile, and running it to discover the new system or systems. It also gives you pointers to the asset management and hardware management chapters in the feature guide, which provide a broader range of information about discovering and managing hardware.

How To: Migrating Virtual Machines

One of the big advantages of using Oracle VM Server for x86 or SPARC is the ability to migrate virtual machines. If two Oracle VM Servers are grouped together in a server pool under one Oracle VM Manager, you can perform a live migration to move an Oracle VM to a new server without shutting it down. This can be handy if you need to perform maintenance on one of the Oracle VM Servers but want to minimize the impact.

We've put together a How-To that walks you through a live migration of an Oracle VM and explains the prerequisites and roles required. It also gives you a pointer to some additional resources - the Feature Reference Guide has chapters about Oracle VM Servers for x86 and Server Pools, and the How-To library has a few other How-Tos that relate to VM management.

How To: Enable Single Root I/O Virtualization in Exalogic Elastic Cloud

The Oracle Exalogic Elastic Cloud X2-2 solution includes a set of compute nodes connected through QDR InfiniBand IO Fabric. In order to virtualize the I/O for these nodes, the Single Root Input Output Virtualization (SR-IOV) has to be turned on. However, ILOM and BIOS updates will reset the settings, which prevents virtualization, and causes some headaches if you're trying to get that virtualization working quickly.

So, we put together a How-To that explains how to enable SR-IOV. You can do it through the Ops Center UI or from the command line; the how-to walks you through both ways of doing it, and gives you a pointer over to the Exalogic section of the Feature Reference guide for more info.

How To: Use Monitoring Rules and Policies

One of Ops Center's most useful features is its asset monitoring capability. When you discover an asset - an operating system, say, or a server - a default monitoring policy is applied to it, based on the asset type. This policy contains rules that specify what properties are monitored and what thresholds are considered significant. Ops Center will send a notification if a monitored asset passes one of the specified thresholds.

But sometimes you want different assets to be monitored in different ways. For example, you might have a group of mission-critical systems, for which you want to be notified immediately if their file system usage rises above a specific threshold. You can do so by creating a new monitoring policy and applying it to the group. You can also apply monitoring policies to individual assets, and edit them to meet the requirements of your environment.

The Tuning Monitoring Rules and Policies How-To walks you through all of these procedures.

How To: Create Oracle Solaris Zones

Oracle Solaris Zones are a versatile technology. You can use them to create virtualized Oracle Solaris 10 or 11 operating systems which can independently run a variety of applications. You can also use Ops Center to set up server pools for your zones, which lets you move zones and allocate resources quickly.

Before you can do any of this, though, you need to create zones. In Ops Center, this is a two-step process:

First, you create a profile and a plan. The profile specifies the naming convention and zone details such as the CPU and memory attributes, and the plan specifies how to deploy the profile. You can use the same profile and plan to create zones on multiple systems.

Once you've created a profile and a plan, you run the plan to create zones on the targeted systems, and provide some zone-specific information.

We've created two How To guides that walk you through the whole process of creating Oracle Solaris 10 and Oracle Solaris 11 zones. These How Tos are part of the How To library within the docs site. There's also an article over on the OTN about creating Oracle Solaris 11 zones.

How To: Configure a Virtual Datacenter

Virtualization is a versatile tool. By creating virtual systems and configuring them to share resources, you can adapt your environment quickly to meet changing needs.

Setting up a Virtual Datacenter (vDC) in Ops Center is one way to make effective use of virtualized systems. A vDC lets you discover and pool multiple Oracle VM servers or zones and to make a resource for cloud users.

The How To walks you through discovering the components, setting up the network resources, creating the vDC, and creating accounts to give users access to resources.
