A resource type consists of the following elements:
A software application to be run in the cluster
Control programs that are used as callback methods by the RGM to manage the application as a cluster resource
A set of properties that form part of the static configuration of a cluster
The RGM uses resource type properties to manage resources of a particular type.
In addition to a software application, a resource type can represent other system resources, such as network addresses.
You specify the properties for the resource type and set property values in a resource type registration (RTR) file. The RTR file follows the format that is described in Setting Resource and Resource Type Properties and in the rt_reg(4) man page. See also Defining the Resource Type Registration File for a description of a sample RTR file.
Resource Type Properties provides a list of the resource type properties.
The cluster administrator installs and registers the resource type implementation and underlying application on a cluster. The registration procedure enters the information from the RTR file into the cluster configuration. The Sun Cluster Data Services Planning and Administration Guide for Solaris OS describes the procedure for registering a data service.
