|Oracle Solaris Cluster Concepts Guide Oracle Solaris Cluster 4.0|
Solaris zones provide a means of creating virtualized operating system environments within an instance of the Oracle Solaris OS. Solaris zones enable one or more applications to run in isolation from other activity on your system. The Solaris zones facility is described in Part II, Oracle Solaris Zones, in Oracle Solaris Administration: Oracle Solaris Zones, Oracle Solaris 10 Zones, and Resource Management.
You can create any number of non-global zones. You can use Oracle Solaris Cluster software to manage the availability and scalability of applications that are running on non-global zones.
The Oracle Solaris Cluster HA for Solaris Zones data service manages each zone as a resource that is controlled by the RGM.
Use the Oracle Solaris Cluster HA for Solaris Zones data service if any of following criteria is met:
You require delegated root access.
The application is not supported in a cluster.
You require affinities between resource groups that are to run in different zones on the same node.
If you plan to use the Oracle Solaris Cluster HA for Solaris Zones data service for an application, ensure that the following requirements are met:
The application is supported to run on non-global zones.
The application is integrated with the Oracle Solaris OS through a script, a run-level script, or a Solaris Service Management Facility (SMF) manifest.
The additional failover time that is required to boot a zone is acceptable.
Some downtime during maintenance is acceptable.
For information about how to use the Oracle Solaris Cluster HA for Solaris Zones data service, see Oracle Solaris Cluster Data Service for Oracle Solaris Zones Guide.
