NAME

property_attributes– resource property attributes

DESCRIPTION

The list below describes the resource property attributes that can be used to change system-defined properties or create extension properties.

You cannot specify NULL or the empty string ("") as the default value for boolean, enum, or int types.

Property

The name of the resource property.

Extension

If used, indicates that the RTR file entry declares an extension property defined by the resource type implementation. Otherwise, the entry is a system-defined property.

Description

A string annotation intended to be a brief description of the property. The description attribute cannot be set in the RTR file for system-defined properties.

Property Type

Allowable types are: string, boolean, int, enum, and stringarray. You cannot set the type attribute in an RTR file entry for system-defined properties. The type determines acceptable property values and the type-specific attributes that are allowed in the RTR file entry. An enum type is a set of string values.

Default

Indicates a default value for the property.

Tunable

Indicates when the cluster administrator can set the value of this property in a resource. Can be set to None or False to prevent the administrator from setting the property. Values that allow administrator tuning are: True or Anytime (at any time), At_creation (only when the resource is created), or When_disabled (when the resource is offline).

The default is True (Anytime).

Enumlist

For an enum type, a set of string values permitted for the property.

Min

For an int type, the minimal value permitted for the property. Note that you cannot specify Min=0 for a method timeout.

Max

For an int type, the maximum value permitted for the property. Note that you cannot specify a maximum value for a method timeout.

Minlength

For string and stringarray types, the minimum string length permitted.

Maxlength

For string and stringarray types, the maximum string length permitted.

Array_minsize

For stringarray type, the minimum number of array elements permitted.

Array_maxsize

For stringarray type, the maximum number of array elements permitted.

EXAMPLES

Example 1 An `int` Type Definition

An int type definition might look like this:

{
         PROPERTY = Probe_timeout;
         EXTENSION;
         INT;
         DEFAULT = 30;
         TUNABLE = ANYTIME;
         DESCRIPTION = "Time out value for the probe (seconds)"; 
}
