Beispiele

Dieses Beispiel veranschaulicht die Verwendung der LogPolicy-Klasse und der PolicyUnit-Struktur, um die Richtlinie für eine Protokolldatensatzsequenz festzulegen.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
//

Hinweise

Die PolicyUnit-Struktur stellt eine Größenmessung in einer Protokollspeicherrichtlinie dar.The PolicyUnit structure represents a size measurement in a log store policy. Die PolicyUnitType-Enumeration listet die darstellbaren Maßeinheiten auf.The PolicyUnitType enumeration lists the units of measurement that can be represented.

Sie können die Value-Eigenschaft verwenden, um die Größe der Messung zu bestimmen.You can use the Value property to determine the size of the measurement. Verwenden Sie zum Bestimmen der Maßeinheit die Type-Eigenschaft.To determine the unit of measurement, use the Type property. Sie können andere Datentypen in eine PolicyUnit konvertieren, indem Sie die Percentage-Methode und die Extents-Methode verwenden.You can convert other data types to a PolicyUnit by using the Percentage and Extents methods.
