Resources

A resource inherits the properties and values of its resource type. In addition, you can declare resource properties in the RTR file. Resource Properties contains a list of resource properties.

The cluster administrator can change the values of particular properties depending on how the properties are specified in the RTR file. For example, property definitions can specify a range of allowable values. Property definitions can also specify when the property is tunable: never, any time, at creation (when the resource is added to the cluster), or when the resource is disabled. Within these specifications, the cluster administrator can make changes to properties by using administration commands.

The cluster administrator can create many resources of the same type, with each resource having its own name and set of property values, so that more than one instance of the underlying application can run in the cluster. Each instantiation requires a unique name within the cluster.
