.NET Framework (current version)
Specifies the unit of measurement of a PolicyUnit instance.
Assembly: System.IO.Log (in System.IO.Log.dll)
The measurement is in containers.
The measurement is a percentage of the size of the LogStore.
// 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 //
