예외

InvalidOperationException

로그에 설치된 정책 집합이 잘못된 경우

또는

로그의 정책에 따라 이 작업이 완료되지 못한 경우

IOException

예기치 못한 I/O 예외 때문에 요청을 수행할 수 없는 경우

NotSupportedException

현재 플랫폼에서 이 정책을 설정할 수 없는 경우

ObjectDisposedException

시퀀스가 삭제된 후 메서드가 호출된 경우

OutOfMemoryException

메모리가 부족하여 프로그램을 계속 실행할 수 없는 경우

PathTooLongException

새 범위 접두사가 잘못되었거나 너무 긴 경우. 유효한 접두사를 제공해야 합니다.

SequenceFullException

레코드 시퀀스가 꽉 찼습니다.

UnauthorizedAccessException

지정된 로그 저장소에 대한 액세스가 운영 체제에서 거부된 경우

예제

이 예제에서는 LogPolicy 클래스를 사용하여 로그 레코드 시퀀스에 대한 정책을 설정하는 방법을 보여 줍니다.

// 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.
