About Branded Zones

By default, a non-global zone on a system runs the same operating system software as the global zone. The branded zone (BrandZ) facility in the Oracle Solaris operating system is a simple extension of Oracle Solaris Zones. The BrandZ framework is used to create non-global branded zones that contain operating environments that are different from that of the global zone. Branded zones are used on the Oracle Solaris operating system to run applications. The BrandZ framework extends the Oracle Solaris Zones infrastructure in a variety of ways. These extensions can be complex, such as providing the capability to run different operating system environments within the zone, or simple, such as enhancing the base zone commands to provide new capabilities. For example, the Oracle Solaris 10 Container is a branded non-global zone that can emulate the Oracle Solaris 10 operating system. Even default zones that share the same operating system as the global zone are configured with a brand.

The brand defines the operating environment that can be installed in the zone, and determines how the system will behave within the zone so that the software installed in the zone functions correctly. In addition, a zone's brand is used to identify the correct application type at application launch time. All branded zone management is performed through extensions to the standard zones structure. Most administration procedures are identical for all zones.

The resources included in the configuration by default, such as defined file systems and privileges, are covered in the documentation for the brand.

BrandZ extends the zones tools in the following ways:

Although you can configure and install branded zones on an Oracle Solaris Trusted Extensions system that has labels enabled, you cannot boot branded zones on this system configuration, unless the brand being booted is the labeled brand on a certified system configuration.

You can change the brand of a zone in the configured state. Once a branded zone has been installed, the brand cannot be changed or removed.


Caution - If you plan to migrate your existing Oracle Solaris 10 system into a solaris10 branded zone on a system running the Oracle Solaris 11 Express release, you must migrate any existing zones to the target system first. Because zones do not nest, the system migration process renders any existing zones unusable. See Part III, Oracle Solaris 10 Zones for more information.

Processes Running in a Branded Zone

Branded zones provide a set of interposition points in the kernel that are only applied to processes executing in a branded zone.

A brand can also provide a plug-in library for librtld_db. The plug-in library allows Oracle Solaris tools such as the debugger, described in mdb(1), and DTrace, described in dtrace(1M), to access the symbol information of processes running inside a branded zone.

Branded Zones Available in this Release

In addition to the default ipkg brand, Oracle Solaris 10 Zones (solaris10 branded zones) is included in this release. For more information, see Part III, Oracle Solaris 10 Zones.
