Systemdefinierte Eigenschaften in der RTR-Datei

Die folgende Auflistung zeigt die systemdefinierten Eigenschaften in einer RTR-Beispieldatei. 

# A list of bracketed resource property declarations follows the
# resource type declarations. The property-name declaration must be
# the first attribute after the open curly bracket of each entry.

# The <method>_timeout properties set the value in seconds after which
# the RGM concludes invocation of the method has failed.

# The MIN value for all method timeouts is set to 60 seconds. This
# prevents administrators from setting shorter timeouts, which do not
# improve switchover/failover performance, and can lead to undesired
# RGM actions (false failovers, node reboot, or moving the resource group
# to ERROR_STOP_FAILED state, requiring operator intervention). Setting
# too-short method timeouts leads to a *decrease* in overall availability
# of the data service.

   PROPERTY = Start_timeout; 
   MIN=60; 
   DEFAULT=300;

{
   PROPERTY = Retry_count;
   MIN=0;
   MAX=10;
   DEFAULT=2;
   TUNABLE = ANYTIME; 
}

# Set Retry_interval as a multiple of 60 since it is converted from seconds
# to minutes, rounding up. For example, a value of 50 (seconds)
# is converted to 1 minute. Use this property to time the number of 
# retries (Retry_count).

Obwohl die Sun Cluster-Software die systemdefinierten Eigenschaften liefert, können Sie mithilfe von Ressourceneigenschaftsattributen verschiedene Standardwerte festlegen. Eine vollständige Liste mit Attributen, die Ihnen zum Anwenden auf Ressourceneigenschaften zur Verfügung stehen, finden Sie im Abschnitt Ressourceneigenschaftsattribute.

Beachten Sie die folgenden Punkte zu den systemdefinierten Ressourceneigenschaften in der RTR-Beispieldatei:
