A resource inherits the properties and values of its resource type. In addition, a developer can declare resource properties in the resource type registration file. See Table A–2 for a list of resource properties.
The cluster administrator can change the values of certain properties depending on how they were specified in the resource type registration (RTR) file. For example, property definitions can specify a range of allowable values and specify when the property is tunable, for example, at creation, anytime, or never. Within these specifications, the cluster administrator can make changes to properties using administration commands.
The cluster administrator can create many resources of the same type, each resource having its own name and set of property values, so that more than one instance of the underlying application can run on the cluster. Each instantiation requires a unique name within the cluster.
