Setting Standard Properties

You can specify standard cluster, resource type, resource, and resource group properties when configuring data services. Resource property attributes are also available to change system-defined properties and create extension properties.

Cluster Properties

Cluster properties are used to manage data services. For information about cluster properties, see the cluster(1CL) man page.

Resource Type Properties

Resource type properties cannot be updated by administrative utilities with the exception of Installed_nodes and RT_system. Installed_nodes cannot be declared in the RTR file and can only be set by the cluster administrator. RT_system can be assigned an initial value in the RTR file, and can also be set by the cluster administrator.

For information about each resource type property that is defined by Oracle Solaris Cluster software, see the rt_properties(5) man page.

Resource Properties

For information about each resource property that is defined by Oracle Solaris Cluster software, see the r_properties(5) man page.

Resource Group Properties

For information about each resource group property that is defined by Oracle Solaris Cluster software, see the rg_properties(5) man page.

Resource Property Attributes

You can use resource property attributes to change system-defined properties or to create extension properties. For information about each property, see the property_attributes(5) man page.
