Effects of State Changes to Oracle Solaris Cluster Resources for Support for Oracle RAC Database
Instances
Oracle Grid Infrastructure manages the startup and shutdown of Oracle Database instances, listeners, and other
components that are configured in the Oracle Grid Infrastructure. Oracle Grid Infrastructure is a mandatory component. Oracle Grid Infrastructure also monitors
components that are started by Oracle Grid Infrastructure and, if failures are detected, perform actions to recover from
failures.
Because Oracle Grid Infrastructure manages the startup and shutdown of Oracle database components, these
components cannot be stopped and started exclusively under the control of the Oracle Solaris Cluster
RGM. Instead, Oracle Grid Infrastructure and the RGM interoperate so that when Support for Oracle RAC database
instances are started and stopped by Oracle Grid Infrastructure, the state of the database instances is propagated to
Oracle Solaris Cluster resources.
The following table describes the state changes that occur between Oracle Solaris Cluster resources and
Oracle Grid Infrastructure resources.

The names of the states of Oracle Solaris Cluster resources and Oracle Grid Infrastructure resources are identical.
However, the meaning of each state name is different for Oracle Solaris Cluster resources and Oracle Grid Infrastructure
resources. For more information, see the following table.
Table 16 Comparisons of States for Oracle Solaris Cluster Resources and Oracle Grid Infrastructure Resources
|
|
|
Enabled
|
The resource is available to the Oracle Solaris Cluster RGM for automatic startup, failover, or
restart. A resource that is enabled can also be in either the online state or the offline
state.
|
The resource is available to run under Oracle Grid Infrastructure for automatic startup, failover, or restart. A
resource that is enabled can also be in either the online state or the offline state.
|
Disabled
|
The resource is unavailable to the Oracle Solaris Cluster RGM for automatic startup, failover,
or restart. A resource that is disabled is also offline.
|
The resource is unavailable to run under Oracle Grid Infrastructure for automatic startup, failover, or restart. A
resource that is disabled can also be in either the online state or the offline state.
|
Online
|
The resource is running and providing service.
|
The resource is running and providing service. A resource that is online must also be
enabled.
|
Offline
|
The resource is stopped and not providing service.
|
The resource is stopped and not providing service. A resource that is offline can also be in
either the disabled state or the enabled state.
