The RGM controls data services (applications) as resources, which are managed by resource type implementations. These implementations are either supplied by Oracle or created by a developer with a generic data service template, the Data Service Development Library API (DSDL API), or the Resource Management API (RMAPI). The cluster administrator creates and manages resources in containers called resource groups. The RGM stops and starts resource groups on selected nodes in response to cluster membership changes.
The RGM acts on resources and resource groups. RGM actions cause resources and resource groups to move between online and offline states. A complete description of the states and settings that can be applied to resources and resource groups is located in Resource and Resource Group States and Settings.
Refer to Data Service Project Configuration for information about how to launch Oracle Solaris projects under RGM control.
