Resource Type Properties in the Sample RTR File

The sample RTR file begins with comments followed by resource type properties that define the HA-DNS configuration, as shown in the following listing.

Property names for resource groups, resources, and resource types are not case sensitive. You can use any combination of uppercase and lowercase letters when you specify property names.

Resource_type = “sample”;
Vendor_id = SUNW;
RT_description = “Domain Name Service on Sun Cluster”;

RT_version =”1.0”; 
API_version = 2;    
Failover = TRUE;

RT_basedir=/opt/SUNWsample/bin;
Pkglist = SUNWsample;

Start         =   dns_svc_start;
Stop          =   dns_svc_stop;

Validate      =   dns_validate;
Update        =   dns_update;

Monitor_start =   dns_monitor_start;
Monitor_stop  =   dns_monitor_stop;
Monitor_check =   dns_monitor_check;

You must declare the Resource_type property as the first entry in the RTR file. Otherwise, registration of the resource type fails.

The following information describes these properties:

• You can specify the resource type name by the Resource_type property alone (sample) or by using the vendor-id as a prefix, followed by a period (.), followed by the resource type property (SUNW.sample).

  If you specify vendor-id, use the stock exchange symbol of the company that is defining the resource type. The resource type name must be unique in the cluster.

• The RT_version property identifies the version of the sample data service as specified by the vendor.

• The API_version property identifies the Sun Cluster version. For example, API_version = 2 indicates that the data service can run on any version of Sun Cluster starting with Sun Cluster 3.0. API_version = 7 indicates that the data service can be installed on any version of Sun Cluster starting with 3.2. However, API_version = 7 also indicates that the data service cannot be installed on any version of Sun Cluster that was released before 3.2. This property is described in more detail under the entry for API_version in Resource Type Properties.

• Failover = TRUE indicates that the data service cannot run in a resource group that can be online on multiple nodes at the same time.

• RT_basedir points to /opt/SUNWsample/bin as the directory path to complete relative paths, such as callback method paths.

• Start, Stop, and Validate provide the paths to the respective callback method programs that are run by the RGM. These paths are relative to the directory that is specified by RT_basedir.

• Pkglist identifies SUNWsample as the package that contains the sample data service installation.

Resource type properties that are not specified in this RTR file, such as Single_instance, Init_nodes, and Installed_nodes, are set to their default values. Resource Type Properties contains a complete list of the resource type properties, including their default values.

The cluster administrator cannot change the values for resource type properties in the RTR file.
