Public Property GrowthRate As PolicyUnit

Valore della proprietà

PolicyUnit

Velocità di espansione automatica dell'istanza LogStore.

Esempio

In questo esempio viene illustrato come utilizzare la classe LogPolicy per impostare criteri per una sequenza del record del registro.

// 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
//

Commenti

Quando l'istanza LogStore risulta piena, questo valore del criterio determina la quantità di spazio che è possibile aggiungere. Lo spazio non verrà aggiunto se in conseguenza di tale aggiunta il numero di extent nell'istanza LogStore supera il valore di MaximumExtentCount.
