9.3 ORACLE ENTERPRISE MANAGER OPS CENTER using barcode printing for software control to generate, create barcode standards 128 image in software applications. Recommended GS1 barcodes for mobile apps Wizards greatly simpli Code 128A for None fy Ops Center tasks, especially OS provisioning. These wizards hide the implementation details of those different installation tools. Provisioning quality is strengthened by the use of a software dependency engine to avoid errors and omission of OS components.

Provisioning is also simpli ed by the use of a library of OS pro les and images. An image is a copy of an installable OS distribution. In addition to vendorsupplied images (which are often distributed as ISO les on DVDs), you can create your own images for example, a Solaris Flash Archive (FLAR).

Pro les specify particular con gurations of an OS, starting with an OS image. For instance, you might de ne a web server pro le using an image of a particular Solaris 10 update and specifying a list of OS packages to be installed. An OS pro le library includes multiple pro les.

In addition to using images that include all of the OS packages, your library might include an image precon gured to be a database server. With that pro le in your OS library, provisioning a new DB server is as simple as identifying the target system and the pro le, and letting Ops Center do all of the work. Ops Center delivers the image and updates its repository of system information and a new system is soon waiting for SQL commands.

3 Provisioning L ogical Domains Ops Center has special features for SPARC CMT systems and Logical Domains. Every CMT system has the ability to host Logical Domains. If a CMT system will include guest domains, it must rst have a special-purpose domain called the control domain.

You use the control domain to create and otherwise manage other domains, including service domains and I/O domains. See 3, Oracle VM Server for SPARC, for more information about SPARC CMT systems and Logical Domains. You can use Ops Center to install a control domain on a CMT system, an action that also installs a VC on the control domain to create and manage other domains.

Ops Center also automatically uses the control domain as the service and I/O domains. After the control domain has been installed, Ops Center can install guest domains. Although a primary goal of Ops Center is the simpli cation of one operation being performed on many systems in a data center, it provides additional functionality.

For example, a virtual pool is a set of domains con gured to run on a set of SPARC CMT systems. Using this feature, you can enable Ops Center to automatically load-balance the domains across the systems. Whenever a domain in the virtual pool boots, it will boot on the most lightly loaded system in the pool.

You can also con gure a domain to automatically restart on a running system in the pool if the system it was running on suddenly halts. Because all of the domains in one VP use shared storage, they can easily be moved from one CMT system to another to balance the load on the computers..

4 Provisioning O Code 128B for None racle Solaris Containers You can also provision, update, manage, and monitor Containers with Ops Center on both x86 and SPARC systems. A BUI wizard guides you through the process of con guring the Container, include choosing a computer for it, assigning network connections and le system access, and setting resource controls. Ops Center installs a VC in that computer s global zone.

Figure 9.5 shows the wizard that simpli es the process of creating a Container..

Figure 9.5 Oracle Solaris Container Con guration Wizard 9.3.6 Updating Assets Ops Center 2.5 can upd ate rmware for Sun systems, whether they are based on x86 or on SPARC CPUs. Updating the rmware on a CMT system also updates the Logical Domains hypervisor rmware.

Ops Center also updates Oracle Solaris, popular Linux distributions, and Microsoft Windows. Table 9.1 lists the speci c versions that are supported.

A software agent deployed on each OS instance performs these updates. In addition to replacing or patching live OS packages, the agent for Solaris 10 can discover and update the Alternate Boot Environment (ABE), which is the basis of the Live Upgrade feature. The use of Live Upgrade signi cantly reduces the service outage, if any, needed when patching the OS.
