この例では、LogPolicy クラスおよび PolicyUnit 構造体を使用してログのレコード シーケンスのポリシーを設定する方法を示します。This example shows how to use the LogPolicy class and PolicyUnit structure to set policy for a log record sequence.

// SET LOG POLICY

LogPolicy policy = sequence.LogStore.Policy;

// Set AutoGrow policy. This enables the log to automatically grow
// when the existing extents are full. New extents are added until
// we reach the MaximumExtentCount extents.
// AutoGrow policy is supported only in Windows Vista and not available in R2.

//policy.AutoGrow = true;

// Set the Growth Rate in terms of extents. This policy specifies
// "how much" the log should grow. 
policy.GrowthRate = new PolicyUnit(2, PolicyUnitType.Extents);

// Set the AutoShrink policy. This enables the log to automatically
// shrink if the available free space exceeds the shrink percentage. 
// AutoGrow/shrink policy is supported only in Windows Vista and not available in R2.

//policy.AutoShrinkPercentage = new PolicyUnit(30, PolicyUnitType.Percentage);

// Set the PinnedTailThreshold policy.
// A tail pinned event is triggered when there is no
// log space available and log space may be freed by advancing the base.
// The user must handle the tail pinned event by advancing the base of the log. 
// If the user is not able to move the base of the log, the user should report with exception in
// the tail pinned handler.
// PinnedTailThreashold policy dictates the amount of space that the TailPinned event requests 
// for advancing the base of the log. The amount of space can be in percentage or in terms of bytes 
// which is rounded off to the nearest containers in CLFS. The default is 35 percent.


policy.PinnedTailThreshold = new PolicyUnit(10, PolicyUnitType.Percentage);

// Set the maximum extents the log can have.
policy.MaximumExtentCount = 6;

// Set the minimum extents the log can have.
policy.MinimumExtentCount = 2;

// Set the prefix for new containers that are added. 
// when AutoGrow is enabled.
//policy.NewExtentPrefix = "MyLogPrefix";

// Set the suffix number for new containers that are added.
// when AutoGrow is enabled. 
policy.NextExtentSuffix = 3;

// Commit the log policy.
policy.Commit();

// Refresh updates the IO.Log policy properties with current log policy 
// set in the log. 
policy.Refresh();

// LOG POLICY END
//

注釈

PolicyUnit 構造体は、ログ ストア ポリシーでのサイズ測定値を表します。The PolicyUnit structure represents a size measurement in a log store policy. PolicyUnitType 列挙体には、表すことができる単位がリストされます。The PolicyUnitType enumeration lists the units of measurement that can be represented.

測定値のサイズを確認するには、Value プロパティを使用します。You can use the Value property to determine the size of the measurement. 単位を確認するには、Type プロパティを使用します。To determine the unit of measurement, use the Type property. PolicyUnit メソッドおよび Percentage メソッドを使用して、他のデータ型を Extents に変換できます。You can convert other data types to a PolicyUnit by using the Percentage and Extents methods.

コンストラクター
