Sun Cluster: Guía del desarrollador de los servicios de datos del sistema operativo Solaris

Propiedades definidas por el sistema en el archivo RTR

La siguiente lista muestra las propiedades definidas por el sistema en el archivo RTR de ejemplo.

# 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 = Stop_timeout; 
   MIN=60; 
   DEFAULT=300;
}
{
   PROPERTY = Validate_timeout;
   MIN=60;
   DEFAULT=300;
}
{
   PROPERTY = Update_timeout;
   MIN=60;
   DEFAULT=300;
}
{
   PROPERTY = Monitor_Start_timeout;
   MIN=60;
   DEFAULT=300;
}
{
   PROPERTY = Monitor_Stop_timeout;
   MIN=60;
   DEFAULT=300;
}
{
   PROPERTY = Thorough_Probe_Interval;
   MIN=1;
   MAX=3600;
   DEFAULT=60;
   TUNABLE = ANYTIME;
}

# The number of retries to be done within a certain period before concluding 
# that the application cannot be successfully started on this node.
{
   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).
{
   PROPERTY = Retry_interval;
   MIN=60;
   MAX=3600;
   DEFAULT=300;
   TUNABLE = ANYTIME;
}

{
   PROPERTY = Network_resources_used;
   TUNABLE = AT_CREATION;
   DEFAULT = ““;
}

Aunque el software de Sun Cluster proporciona las propiedades definidas por el sistema, puede establecer diferentes valores predeterminados mediante el uso de los atributos de propiedades del recurso. Consulte Atributos de las propiedades de recursos para obtener una lista completa de los atributos disponibles que se pueden aplicar a las propiedades del recurso.

Tenga en cuenta los siguientes puntos sobre las propiedades de recursos definidas por el sistema en el archivo RTR de ejemplo:
