RTR ファイルのシステム定義プロパティー

次のリストは、サンプル RTR ファイルのシステム定義プロパティーを示しています。

# 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;

{
   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).

Sun Cluster ソフトウェアはシステム定義プロパティーを提供しますが、リソースプロパティー属性を使用すると、異なるデフォルト値を設定できます。リソースプロパティーに適用するために利用できる属性の完全なリストについては、「リソースプロパティーの属性」を参照してください。
